Now, a team of biologists including Raymond Surzycki and Jean-David Rochaix from the University of Geneva, and Laurent Cournac and Gilles Peltier, both from the Atomic Energy Commission, the National Center for Scientific Research, and the Mediterranean University, have demonstrated a new method for hydrogen production by algae. In a recent issue of PNAS, the team presented a method using copper to block oxygen generation in the cells of Chlamydomonas reinhardtii that could lead to a consistent cycle of hydrogen production.In order to induce hydrogen production in the algae, cells must be placed in an environment without oxygen but with access to light. To completely deplete the algae’s oxygen supply, the researchers turned off part of a chloroplast gene required for oxygen evolution by adding copper to the cells in an enclosed chamber. Specifically, the addition of copper turned off the Cyc6 promoter, which drives the Nac2 gene, which is required for photosystem II (PSII) synthesis. PSII generates oxygen.Within about three hours, nearly all the oxygen was consumed by respiration, and the algae reached an anaerobic state. Without oxygen, the algae began to synthesize hydrogenase and then produce hydrogen.“Hydrogenase is an enzyme that produces hydrogen by combining electrons derived from the photosynthetic electron transport chain with protons,” Rochaix explained to “It is only produced under anaerobic conditions because the photosynthetically produced oxygen is highly toxic to the hydrogenases.”One of the most significant differences between this method and earlier methods is using copper addition rather than sulfur depletion to repress photosynthetic activity. In past experiments, when the cells’ sulfur was depleted, the cells stopped growing and died after a few days. However, when adding copper, the biologists observed that the cells remained healthy. The rate of hydrogen production in the plants with copper was slightly lower than that of sulfur-depleted plants, but comparable.The scientists also observed that, in healthy cells, the Cyc6 promoter doesn’t stay repressed for long due to “anaerobiosis”—the ability of the cells to survive (and repair) with lack of oxygen. Subsequently, PSII activity is restored, and the cell returns to producing oxygen. What happens when you explode a chemical bond?

Universal transistor serves as a basis to perform any logic function

first_img The researchers who designed the transistor, led by Walter M. Weber at Namlab gGmbH in Dresden, Germany, have published the new concept in a recent issue of Nano Letters.“Synthetic nanowires are used to realize the proof-of-principle,” Weber told “However, the concept is fully transferable to state-of-the-art CMOS silicon technology and can make use of self-aligned processes.”The new transistor’s core consists of a single nanowire made of a metal-semiconductor-metal structure, which is embedded in a silicon dioxide shell. Electrons or holes flow from the source at one end of the nanowire through two gates to the drain at the other end of the nanowire. The two gates control the flow of electrons or holes in different ways. One gate selects the transistor type by choosing to use either electrons or holes, while the other gate controls the electrons or holes by tuning the nanowire’s conductance.Using a gate to select p- or n-type configuration is quite different from conventional transistors. In conventional transistors, p- or n-type operation results from doping that occurs during the fabrication process, and cannot be changed once the transistor is made. In contrast, the reconfigurable transistor doesn’t use any doping. Instead, an external voltage applied to one gate can reconfigure the transistor type even during operation. The voltage causes the Schottky junction near the gate to block either electrons or holes from flowing through the device. So if electrons are blocked, holes can flow and the transistor is p-type. By applying a slightly different voltage, the reconfiguration can be switched again, without interfering with the flow.The scientists explain that the key to making this reconfiguration work is the ability to tune the electronic transport across each of the two junctions (one per gate) separately. Their simulations showed that the current is dominated by tunneling, suggesting that the nanowire geometry plays an important role in the ability for independent junction control. Because the reconfigurable transistor can perform the logic functions of both p- and n-type FETs, a single transistor could replace both a p- and n-type FET in a circuit, which would significantly reduce the size of the circuit without reducing functionality. Even at this early stage, the reconfigurable transistor shows very good electrical characteristics, including a record on/off ratio and reduced leakage current compared to conventional nanowire FETs. In the future, the researchers plan to further improve the transistor’s performance.“We are varying the material combinations to further boost device performance,” Weber said. “Further on, first circuits implementing these devices are being built. … The biggest challenge will be to incorporate the extra gate signals in the cell layout allowing flexible interconnection to the other transistors.” The reconfigurable transistor’s core consists of a nanowire structure embedded in a silicon dioxide shell. Electrons or holes flow from the source at one end of the nanowire through two gates to the drain at the other end of the nanowire. One gate is used to program the p- or n-polarity, whereas the other gate tunes the conductance through the nanowire. Image credit: ©Namlab gGmbH ( — Most of today’s electronics devices contain two different types of field-effect transistors (FETs): n-type (which use electrons as the charge carrier) and p-type (which use holes). Generally, a transistor can only be one type or the other, but not both. Now in a new study, researchers have designed a transistor that can reconfigure itself as either n-type or p-type when programmed by an electric signal. A set of these “universal transistors” can, in principle, perform any Boolean logic operation, meaning circuits could perform the same number of logic functions with fewer transistors. This advantage could lead to more compact hardware and novel circuit designs.

We describe here new experiments revealing that slip events in cohesive powders also produce electrical signals, and remarkably these signals can appear significantly in advance of slip events. We have confirmed this effect in two different experimental systems and using two common powdered materials, and in a third experiment we have demonstrated that similar voltage signals are produced by crack-like defects in several powdered materials.

Towards a global quantum network Photoelectron trapping in double quantum dots

More information: Nondestructive Real-Time Measurement of Charge and Spin Dynamics of Photoelectrons in a Double Quantum Dot, Physical Review Letters 110, 266803 (2013), doi:10.1103/PhysRevLett.110.266803 Researchers entangle a single electron spin to a single photon in a quantum dot Explore further (color online). (a) A scanning electron micrograph of the typical lateral DQD device. The surface gates for dot formation have Tið10 nmÞ=Auð20 nmÞ metal thickness. A 60 nm thick Al2O3 insulating layer was formed on top of them by atomic layer deposition.

The excitation laser energy is tuned just above the GaAs band gap. The excited electron-hole pair is separated due to the intrinsic electric field. Copyright © doi:10.1103/PhysRevLett.110.266803 To successfully address these challenges, Fujita explains, the scientists relied on a small number of key insights and innovations. “A significant innovation was to introduce an additional infrared laser beam so that persistent photoconductivity would be erased. This was an innovative scheme because it made it possible to continuously experiment with photon irradiation single-shot single photon detection and obtain series of data.” Another technique, he continues, was to form different kinds of charge sensors to improve the signals in DC measurements.Several other interesting results were achieved in this study, one being that the researchers’ approach offers a novel method to study the multielectron dynamics which are strongly affected by the Coulomb interaction in a multidot system. “Photoexcitation can create multiple electrons within the pulse duration, and the excited spins depend thoroughly upon the incident polarization,” Fujita points out. “This allows initialization of multiple spins and multiple coupled dot experiments.”The demonstrated results can also be regarded as excited state spectroscopy, in that they correspond to a spin excitation over the ground state of the dot, which is an excited state. “Excited states reflect the configuration of the quantum dot which could be modified by tuning the gate voltages,” Fujita notes. “Using our scheme we can investigate energy and spin correlations of excited states using photoelectrons through interdot interactions.”The paper also reports that fast initialization of the excited states can be realized by controlling the incident photon number, energy, and polarization. “Photon number could be tuned with the laser power, energy with the wavelength, and spin polarization with the photon polarization,” Fujita explains. “The photon configurations are tuned in the optics and excitation could be realized fast within the laser pulse width. If we compare this with electrical initialization by tunneling from the leads, the initialization time is limited by the tunneling rate and exact spins are currently difficult to inject.”Using the resonant interdot tunneling in the DQDs, the researchers’ technique would also open a way to high fidelity photon counting. “Our technique to keep the photoelectrons from escaping is an advantage for counting multiple photoelectrons,” Fujita says. “We’ve shown that tunneling rates could be properly tuned in a desired range. This enables us to tune the tunneling of each electron number to a good tunneling rate so that every electron tunneling could be resolved and give us a higher fidelity.”Fujita also comments on the relationship between their findings and the no-cloning theorem, which he points out holds that quantum communication becomes perfectly safe – but on the other hand, there’s also no way to amplify a quantum state to extend the communication length. This therefore restricts the length of quantum information transfer with a single photon. “Quantum repeaters would shorten each photon propagation,” Fujita notes, “thus making it possible to connect between more distant places – and we’ve demonstrated a scheme that brings us closer to the realization of a quantum repeater.”More specifically, in the current study a quantum repeater is shown as a solution for extending the quantum communication length. “We think our demonstrated nondestructive single-shot single photon detection in lateral quantum dots is a good candidate for one of the ingredients of this repeater,” Fujita tells “In the future it could realize determination and storage of the arrived photons to immediately create entanglement at its convenience to raise the entanglement creation rate. Further integration of quantum operations in our quantum dot would possibly move the establishment of information network forward, and thereby impact the establishment of a global quantum information network.””We’ve demonstrated the detection of photoelectron spin configuration using two electron spin correlation, namely the spin blockade, so next we’ll detect single photoelectron spin by correctly initializing the prepared spin.” Fujita adds. “Our next step is to combine our photoelectron spin detection scheme with heavy hole excitations to verify angular momentum transfer,” In terms their continued research, Fujita says that the researchers would like to verify the angular momentum transfer to the electron spins. “This requires selective excitation of electron hole spin states, so a wavelength-tunable single shot irradiation setup is needed. Another development,” he continues, “would be to increase the photon absorption rate at a scale that would permit realizing sufficient entanglement between photons and electron spins.” The scientists are also thinking of embedding Bragg reflectors inside the wafer.Over the next decade, Fujita continues, their research would lead to the entanglement between distant solid state qubits by trapping entangled photon pairs. “After the verification of coherent angular momentum transfer, experiments on trapping entangled photon pairs will be demonstrated to verify the entanglement between photons and electron spins. The advantage of our lateral quantum dot is that 2-spin qubit operations could be done,” Fujita concludes. “This will be then demonstrated in two trapped photons to create entanglement between distant entangled photon pairs.” Recently, however, scientists at The University of Tokyo, Princeton University, Ruhr-Universität Bochum, and RIKEN found that nondestructive measurement is feasible using gallium arsenide double quantum dots (DQDs), thereby taking a significant step towards long distance entanglement distribution. Moreover, the importance of using a lateral dot is that these have a possibility to store and manipulate the photoelectrons – and while previous studies show detection of photocurrents or photoelectron signals, the scientists state that to their knowledge, none of them performed experiments demonstrating the possibility of further photoelectron storage or manipulation. Lastly, although the researchers have not yet demonstrated the spin manipulation of photoelectrons, their double dot structure shows repetitive tunneling of single photoelectrons, and so satisfies the photoelectron spin manipulation condition.Researcher Takafumi Fujita discussed the research he, Prof. Seigo Tarucha, and their colleagues conducted with “The main challenge in demonstrating the trapping of single photons and interdot tunneling of the photogenerated electrons in a nondestructive manner using double quantum dots was to stabilize our quantum dot while performing single-shot single photon detection experiments,” Fujita tells “Conventional lateral quantum dot devices can change their condition upon irradiation. We had to fine-tune and maintain the resonant interdot tunneling condition while performing irradiation experiments. The photon responses do not recover immediately so repetition of the irradiation sequence also had to be tuned to wait for photoconductivity to relax.”Regarding the use of resonant tunneling, Fujita explains, the idea of using a double dot was to use spin blockade, but the researchers also had to clearly distinguish photoelectron trapping signals from the noise. Rather than using a single-step signal – which can be difficult to distinguish in photon irradiation measurements – they decided to use iterative bi-stable charge tunneling signals in the double dot to clearly discriminate single photoelectron trapping events from noise. “With iterative bi-stable charge tunneling to determine the number of trapped photoelectrons,” Fujita adds, “we had to wait in order to be certain that there were no other electrons left in the dot. However, we found that the resonant interdot tunneling would give us an immediate response of the last remaining electron.” In addition, says Fujita, to infer photoelectron spin states, the scientists thought that they needed a large number of data samples – but once again, interdot resonance proved to be an advantage. ( —While the journey from today’s fledgling quantum computers to a global quantum information network may seem daunting, researchers are continually, and at an accelerating pace, making progress towards that goal. One key element essential to that progress is the transfer of quantum information between single photons and solid-state quanta – and the properties of semiconductor quantum dots (QDs) make them excellent candidates for photon-electron quantum coupling. One historical stumbling block has been that although quantum circuits require nondestructive transfer between separate dots, using single QDs usually fails due to destructive transfer in which photoelectrons are immediately lost upon measurement.

Astronomers discover an unusual nuclear transient

first_img Although an increasing number of transient astronomical events in the centers of galaxies are being discovered by surveys like the Optical Gravitational Lensing Experiment (OGLE), such phenomena are challenging to detect and study. Given that transients could be explained by various violent deep-sky events, including supernovae, gamma-ray bursts, or tidal disruption events (TDEs), finding new ones is important to better understand their origin.In a recently published paper, astronomers led by Mariusz Gromadzki of Warsaw University Astronomical Observatory in Warsaw, Poland, reports the finding of a peculiar nuclear transient event in the nucleus of the galaxy GALEXASC J015624.70-710415.8, some 680 light years away from the center of the host. OGLE17aaj was detected by the OGLE-IV Transient Detection System in January 2017 and follow-up observations of this transient were performed subsequently using various ground-based and space telescopes.”We report on the discovery and follow-up of a peculiar transient, OGLE17aaj, which occurred in the nucleus of a weakly active galaxy,” the paper reads.The researchers revealed that OGLE17aaj was detected at a host-subtracted I-band magnitude of about 21.0 and reached an I-band maximum magnitude of 20.0 in about 60 days. Afterward, the transient declined for about 200 days and appears to have reached a plateau. The estimated peak absolute magnitude of OGLE17aaj in the I-band was found to be 18.8.Results from ultraviolet measurements of OGLE17aaj follow the trend seen in optical observations. The astronomers noted that at maximum, the transient reached a magnitude of 19.06, and 18.52 on galaxy-subtracted images from NASA’s Swift space telescope.Moreover, the scientists calculated the lower limit on the total energy emitted by OGLE17aaj until now. This value is at a level of approximately 7.0 sexdecillion ergs, what corresponds to a lower limit of the accreted mass of about 0.04 solar masses.The authors of the paper suppose that OGLE17aaj may be a TDE, taking into account its properties, such as: a long rise time, lack of color-temperature evolution, and high black-body temperature. In general, TDEs occur when a star passes fatally close to a supermassive black hole, and is pulled apart by the black hole’s tidal forces.However, narrow emission lines and slow post-peak evolution of the transient, disfavor this hypothesis.”We investigated it as a potential TDE candidate based on its high black-body temperature and on the similarity of its spectrum to that of the recently reported nuclear event in F01004-2237, which was interpreted as a TDE. (…) OGLE17aaj showed a well-covered 60-day-long rise and a slow 200-day decline, followed by a plateau until day 300. This is unlike any TDE reported so far,” the astronomers concluded.

AstroSAT observations reveal quasiperiodic oscillations in the Xray binary GX 51

first_img More information: Yashpal Bhulla et al. AstroSat observation of GX 5-1: Spectral and timing evolution. arXiv:1903.11986 [astro-ph.HE]. X-ray binaries consist of a normal star or a white dwarf transferring mass onto a compact a neutron star or a black hole. Based on the mass of the companion star, astronomers divide them into low-mass X-ray binaries (LMXB) and high-mass X-ray binaries (HMXB). When X-ray light from these objects flickers about certain frequencies, such behavior is known as quasi-periodic oscillations (QPOs). Although many questions about the phenomenon of QPOs remain unanswered, it is believed that they occur when X-rays are emitted near the inner edge of an accretion disk in which gas swirls onto a compact object, for instance, a neutron star or a black hole. Astronomers hope that these oscillations could advance our knowledge the innermost regions of accretion disks.Located near the center of the Milky Way galaxy, some 29,300 light years away from the Earth, GX 5-1 is the second brightest persistent LMXB harboring a neutron star. In February 2017, the binary was observed by the AstroSAT spacecraft – India’s first dedicated multi-wavelength observatory.These observations, using AstroSAT’s Large Area X-ray Proportional Counters (LAXPC) and Soft X-ray imaging Telescope (SXT), allowed a group of astronomers led by Yashpal Bhulla of Pacific Academy of Higher Education and Research University in Udaipur, India, to detect QPOs in GX 5-1 and to collect important data regarding this object.”We present the analysis of an AstroSAT observation of the Z-track source GX 5-1. We used the strictly simultaneous SXT and LAXPC data to track the spectrum of a neutron star source as it moves along its Hardness intensity diagram (HID) and at the same time quantify the rapid temporal variability of the source,” the astronomers wrote in the paper.The observations found that the power spectra of GX 5-1 show a strong QPO whose frequency changes from around 30 to 50 Hz. It was also found that time-lags between high and low energy photons are less than a few milliseconds, and that the QPO frequency increases, while its root mean square (r.m.s) decreases with disk flux ratio.According to the study, these results suggests that the detected QPO originates in the thermal Comptonized component and it weakens when the component is less dominant.”The results suggest that the spectral properties of the source are characterized by the disk flux ratio and that the QPO has its origin in the corona producing the thermal Comptonized component,” the paper reads.The researchers concluded that more studies of GX 5-1, especially a detailed radiative modeling of its energy could be much helpful providing more details about the origin of QPOs in this system. Using the AstroSAT spacecraft, Indian astronomers have observed the low-mass X-ray binary designated GX 5-1. The observations were published March 28 on the arXiv pre-print repository.

Ebola waned but so did human bonds

first_imgHow would you assess the impact of Ebola in the entire African region, particularly the 3 most affected countries?Ebola outbreak was declared in March 2014, but Indian media did not do much at the time, although I tried to reach out. Media around the world put my country or our  three countries in the spotlight. Anyway now everyone knows what’s happening in my country. In fact Ebola fever epidemic killed nearly more than 5,000 and infected close to 10,000 in the the countries- Guinea, Sierra Leone and Liberia. And all those three countries are located in the West African region, so that deadly fever has affected the human relationship, and it has affected the country, the trade, it has affected all the activities in the country. Also Read – FM favours cess over additional tax for compensating statesIn West Africa, we belong to the community called Economic Community of West African States (ECOWAS) where there is no requirement of a visa, if you want to travel from one country to another. Therefore, there is free movement of people and free movement of goods as well. So those three countries are neighboring countries and can see how people are willing to move freely from one country to another. We used to do that, it is more or less the same, just that people have been divided into three territories. It is not easy to control the border. Ebola’s impact has been on every single aspect of human life in the country. It has changed even the way people are behaving. For instance in our country we greet people by a handshake. And today due to the Ebola scare, people are not shaking hands, even blood relations. Also Read – Indian eves lose to NZ in four-nation series openerThis disease has changed the way of life in these three countries. Thanks to the international communities including India, I feel that now it is under control and I was reading a report that said that from next week some vaccines will be available and they will start experimenting. We were supposed to organise the African Cup of Nations. A big soccer event that periodically takes place in Africa. Morocco was supposed to host the event but now the soccer authorities in the country are looking for other countries to host the event for Africa. Similarly, many international conferences that were supposed to take place in Africa have been postponed. Even here in India we were supposed to have the third edition of the African India Forum Summit but it has been cancelled due to the breakout of Ebola. So basically this is my assessment, not only it has affected the three countries but the whole sub region as a whole.  Tell us about its impact on your country?As far as my country is concerned, the latest statistics which came out yesterday,  show that 1,659 people have been infected and 966 have died. The rate of mortality is nearly 58.2 per cent including medical personnel. 94 of the medical staff have been infected and 43 have died. So the rate is nearly 46.23 per cent- which is a lot!What are the steps the government or people are taking to control the disease?Lack of awareness is the main issue. We have to convince the population as a whole that this disease is curable although there is no vaccine yet, to cure. The main steps we have taken is the awareness campaign and which involves all the leadership, all political and religious leaders, the civil servants and the national bodies are involved in the fight. So today, according to statistics, the scope is now decreasing and is stablising. There are no more new infections. This happened because  of what the leadership did in the country. They increased the awareness campaign and told people what to do, what not to do, why to wash hands and what to do incase someone is affected- quickly to be taken to a treatment centre. And whoever that person has contact with has to be followed too, medically speaking. So that’s what the country has been doing, and we have received a lot of support from WHO, from France, from USA, from China, from India, from Canada and from so many countries around the world. So in the near future, before the end of the year, we are hoping to receive a good signal from my country. You see for instance, I was reading from the newspaper that Liberia has waved the state of emergency for medical reasons. That state of emergency has been waved to allow people to move freely because they have assessed that the infection rate is stable and people more and more are understanding that yes the disease is curable – if you go early to the treatment centre, but if you stay home, you wont be cured and you will infect the people surrounding you as well. So that is what we have been doing, I feel that the campaign has been successful.You mentioned that your country has received tremendous response from countries all over the world. Please elaborate.Yes. From Asia: China, India and Malaysia ahve contributed trmemdously. India contributed up to 12.5 million USD to WHO and  which has directly affected countries. And China did a lot as well- they sent logistics, money and even sent personnel. But even while we are talking about some countries making contribution I can’t call it absolute, it is just an overview. From west, France is on the front line. France is even establishing a hospital in one of the affected areas and the French foreign minister is in Guinea since yesterday as we speak. USA has done a lot, they have sent 3,000 trucks to Monrovia in Liberia. United Kingdom, Germany, Netherlands have sent money. Its a concern for everybody in the world as we have seen some cases in USA and also in Spain. People are travelling. People make contact and we cannot stop that. This deadly disease has to be fought strongly. Developing countries are suffering because the health infrastructure is too poor as compared to the developed countries you. So it is a huge cause for every one. And I really appreciate the contribution made by the whole world to fight the disease. And I am sure that in the near future, we will find the appropriate drug to eradicate it completely.Can you please share with me, how do India and Guinea engage with each other. What kind of relationship do they have with each other?I think that should have been the first question. Of course, India and Guinea are friendly countries. They share lot of things in common. Because they are all independent states and they belong to so many international organisations for instance United Nations, Non Aligned Movement and other organisations around the world, so the relationship has enough strategy and history behind it too. India was the first country to open its diplomatic mission in Guinea. Until 1988, India had  an embassy in Conakry but for some reason it was closed down and currently your embassy in Cote D’Ivore, is taking care of Guinea.As far as development is concerned, India has been funding so many projects in Guinea, in the sector of power (energy). India has been providing funding  for the transportation sector. We have more than 100 buses from TATA. Since I am here, we will be working together. India will be funding up to $35 million in the sector of strengthening our health system and nearly $60 million in the sector of agriculture. Some projects are on in the sector of food processing, in providing fertilisers for agriculture, in providing machines for agriculture. In the sector of education we have some students here. When it comes to international affairs and international issues, we support each other. So far we have upto 12-15 students studying in universities and high schools in India. And the number will be increasing as India is allocating every year, scholarship platforms for students from the 8th to the 12th standard. Although as countries, we use different languages, it is not a barrier. I feel that basically as a developing country, India,  being one of the largest democracies in the world has inspired so many countries in Africa including Guinea.last_img read more
