Credit: Photo by Robert Thompson, ALPHA-2 member, University of Calgary Scientists of the international ALPHA Collaboration have once again pushed the boundaries of antimatter research with their latest breakthrough studying the properties of antihydrogen. Published today in the prestigious journal Nature, the collaboration's result improved the measurement of the charge of antihydrogen, essentially zero, by a factor of 20. Their work is the latest contribution in the quest to chase down the answer to the basic antimatter question, "If matter and antimatter were created in equal amounts during the Big Bang, where did all the antimatter go?" "That means the electrical charge of antihydrogen - the antimatter analogue of hydrogen - can be ruled out as the answer to the antimatter question," says York University Professor Scott Menary, an ALPHA member. "The point of the experiment was to search for a clue as to how or where our predictions of nature are wrong," continues Menary. "Something is missing in our understanding otherwise the matter and antimatter at the Big Bang would have annihilated each other and there would be no universe today. The interactions of matter and antimatter must somehow be different." Physics dictates that for every particle of matter there is an oppositely charged antiparticle with an equal mass. An antihydrogen atom should have the exact same charge as hydrogen (zero). That's because the antiproton and antielectron (positron), which make up antihydrogen, should have the exact opposite charge of the proton and electron that make up hydrogen. Dr. Andrea Capra, a former PhD student of Menary's (now at TRIUMF) who played a major role in the analysis behind this result, says, "We take the charge of matter and antimatter for granted, however, you cannot analyze data or make an experiment assuming it's true." This result showed that antihydrogen and hydrogen are indeed both electrically neutral at a level 20 times more precise than before. Since the antiproton charge is also known to a similar precision, the collaboration also has improved the previous best precision on the positron charge by a factor of 25. While both results uphold the Standard Model, they have constrained what possible extensions to it could be. Capra points out that this work addresses one piece of a larger puzzle. When comparing normal matter to antimatter, he says that "there is the piece comparing their charges, the piece comparing their light spectrums, and the piece comparing how they respond to gravity." The latter piece will be investigated by a dedicated experiment, ALPHA-g, spearheaded by the University of Calgary and including the Canadian members of the collaboration. The experiment was the first using the upgraded "ALPHA-2" system which began operation last year. The largest component, the cooling cryostat, was designed and built at TRIUMF and the University of Calgary by a team led by Mechanical Research Engineer Cam Marshall and Research Scientist (now Emeritus) Art Olin. Scientists at Simon Fraser University and the University of British Columbia also contributed to the construction and assembly of the ALPHA-2 apparatus, including the cryostat. Marshall explained that "the cryostat houses a unique octopole magnet with the antimatter trap, into which was fed the laser spectroscopy system, microwave system, liquid helium cooling, super-conducting current leads, diagnostic wiring, and thermal shielding. A lot going on in a small space!" According to Olin, the experiment's success was "facilitated by the stable cryogenic environment and higher trapping rate of this new atom trap." The experiment was tricky because the team had to isolate the antihydrogen within a sophisticated "magnetic bottle" without it coming into contact with matter as it would then annihilate and disappear. Having passed the first test of their upgraded apparatus with flying colours, the ALPHA Collobration is anxious to attack the other even more exciting pieces of the antimatter puzzle in the coming years. "We will now look at the other pieces of the puzzle, such as the colour of the light emitted by antihydrogen, and test whether hydrogen and antihydrogen emit light in the same way," says Capra. "We are also working on measuring the gravitational acceleration of antihydrogen and determining whether matter and antimatter have the same gravitational behaviour. The next several years are going to be very exciting." Explore further: How things break (and why scientists want to know) More information: M. Ahmadi et al.

« U Toronto study measures GDI emissions in urban near-road environment | Main | German team reconfigures Li-S battery for improved performance; new porous conductive separator coating » Researchers at HRL Laboratories, LLC, have achieved the first demonstration of gallium nitride (GaN) complementary metal-oxide-semiconductor (CMOS) field-effect-transistor (FET) technology. In doing so they have established that the semiconductor’s superior transistor performance can be harnessed in an integrated circuit. This breakthrough paves the way for GaN to become the technology of choice for power conversion circuits that are made in silicon today. According to HRL Senior Staff Research Engineer and Principal Investigator Dr. Rongming Chu, GaN transistors have long excelled in both power switching and microwave/millimeter wave applications, but their potential for integrated power conversion has been unrealized. “Unless the fast-switching GaN power transistor is intentionally slowed down in power circuits, chip-to-chip parasitic inductance causes voltage instabilities,” he said. Chu and his colleagues in HRL’s Microelectronics Laboratory have overcome that limitation, developing a GaN CMOS technology that integrates enhancement-mode GaN NMOS and PMOS on the same wafer. Today, GaN transistors are being designed into radar systems, cellular base stations, and power converters such as those found in computer notebook power adaptors. In the near term, GaN CMOS IC applications could include power integrated circuits that manage electricity more efficiently while having a significantly smaller form factor and lower cost, and integrated circuits that can operate in harsh environments, Chu said. In the long term, GaN CMOS has the potential to replace silicon CMOS in a wide range of products, he added. The HRL research team’s demonstration was published in IEEE Electron Device Letters. HRL Laboratories, LLC is a corporate R&D laboratory owned by The Boeing Company and General Motors specializing in research into sensors and materials, information and systems sciences, applied electromagnetics, and microelectronics.

During a planetary entry, the decomposition of the thermal protection system material resin by the pyrolysis process produces strong blowing gases that are injected into the boundary layer. Induced by the blowing gas, the blockage phenomenon has a strong effect on the level of heat-fluxes. For some entries, such as Earth super-orbital re-entries characteristic of sample return missions, blockage is one of the key issues that have to be addressed. Additionally, this phenomenon is strongly linked to turbulence and to the porous aspects of the ablative material. Here, experimental, numerical and flight data available for different missions, involving high level of heat-.uxes, are gathered and discussed. The models for convective blockage found in the literature have been reviewed in order to select a generic way to estimate this phenomenon. It appears from this study that the convective blockage is still not fully understood and that there is no established approach for its accurate modelling since most of the existing correlations possess a high degree of empiricism. & 2012 Elsevier Ltd.

There is an increasing amount of sustainably generated electricity in the form of wind and solar power, but it is not available whenever we want it. Large-scale electricity storage facilities are therefore needed, both for short-term (day and night) and long-term (weekly or seasonal) storage. Batteries are best for short-term storage, whereas artificially produced fuels such as hydrogen are most suitable for long-term energy storage. 'Electricity and hydrogen have always been regarded as two separate, even competing, solutions for energy storage,' said Mulder. 'With the battolyser we have the first integrated battery electrolysis system, which can store and supply electricity very efficiently as a battery, and when the battery is full, it automatically starts splitting water into hydrogen and oxygen using electrolysis. By combining battery technology with electrolysis, we achieve an outstanding overall efficiency of up to 90 percent. The battolyser has also been found to be stable, both in battery and electrolysis mode, even under long, intensive charging, discharging and hydrogen production.' How does it work? he battolyser is based on the 'nickel-iron battery', a type promoted in the twentieth century particularly by Thomas Edison. Mulder commented, 'It's a very robust battery. Original examples are still working. Also, the raw materials are cheap and obtainable anywhere.' While the battery is charging, the electrodes produce two materials (NiOOH and reduced Fe), which are familiar in the world of electrolysis as a catalyst for the chemical reaction that produces hydrogen and oxygen. Thus, the electrodes, in their charged state, enable water to be electrolysed. The fact that nickel-iron batteries also produce hydrogen gas while charging was always regarded as a drawback, explained Mulder, and that was one of the reasons why other types of battery were ultimately more successful. 'With the battery world and the hydrogen world (solar fuels) in competition and not learning much from each other, no-one has ever tried to combine the two and see whether it would be worthwhile – despite the fact that we need both battery storage and fuels.' Mulder therefore built an initial brick-sized prototype with Bernhard Weninger, a student of his. 'It worked straight away. As soon as the battery approached full charge, it started producing hydrogen,' said Mulder. 'In simple terms we are taking advantage of what nature does automatically. We're making smart use of the materials' natural properties without fighting against them.' The unique feature of the nickel-iron system is that the electricity storage and the hydrogen production are both very efficient, so the system is a good way of handling the variability in power availability and prices. Mulder commented, 'If there's plenty of power and the price is low, we store it; if there's even more cheap power, we make hydrogen. And if there's not enough power, making the price high, we feed power back.' Thus the battolyser is effectively in service the whole time, supplying two functions for the price of one. The hydrogen gas produced can subsequently be used as fuel for fuel cells or gas-fired power stations or as a raw material for the chemical industry, for example for the production of ammonia. The next steps involve research into further improvements in efficiency and scaling up what we already have. The Technology Foundation STW has awarded funding for the research programme, and various companies are investing in the research. As John Nijenhuis, TU Delft's Technology Transfer Officer, pointed out, 'The battolyser needs to be scaled up to the size of a shipping container to prove that the technology is also suitable at the scale of the power produced by a large wind turbine.' The aim is to have the large battolyser ready and tested within eighteen months. Research Engineer Yasmina Bennani of Proton Ventures, an engineering consultancy specialising in ammonia production, storage and transport added, 'Hydrogen is our raw material, so we are very interested in ways of producing green hydrogen. The battolyser is unique in that it is also a battery – a good combination, which is particularly efficient for us.' Technology Coordinator Geert Laagland of the electricity utility Nuon envisages using the ammonia produced from sustainable hydrogen as the future fuel for the modern Magnum power station at Eemshaven. 'If there is not enough wind and solar power, we can use the ammonia to supply clean power on a large scale immediately. Nuon is a member of the STW user group. We're very curious about cost price, of course, but also flexibility. How quickly can you switch over?' Large-scale consumption of green electricity will only increase 'What a lot of people don't realise is that we're not only switching to green electricity but we're also going to use far more of it,' stressed Mulder. ''Households are switching away from gas, cars are becoming electric, and by 2050 industry will be carbon neutral. Lots of processes are far more efficient when electrically powered. Electric cars and heating, for instance, could use as much as 80 percent less kWh of energy compared with petrol and gas. On top of this, more and more sustainable energy sources are electrical. We shall therefore be using three to five times more electricity than at present,' estimated Mulder, and at the same time we shall be saving energy (currently only 13 percent of all energy is used in the form of electricity). To achieve this sustainability and improvement in efficiency, however, power needs to be available throughout the year. 'The battolyser provides us with an efficient, cheap, large-scale, robust way of storing electricity that can be switched back and forth between electricity and hydrogen as often as is needed. Thus, the battolyser is the first to bring together naturally the electricity storage infrastructure and the hydrogen gas production infrastructure.' More information: F. M. Mulder et al.
