Scientists at MIPT have found a possible explanation for the anomalously fast release of gas from nuclear fuel. Supercomputer simulations have uncovered an unexpected mechanism for accelerating the escape of gas bubbles from the uranium dioxide crystal matrix to the surface.
A team of researchers led by Aarhus University and including experts from universities and knowledge institutions in the US, Europe, Japan and Australia has published an article in the prestigious scientific journal Joule confirming that the role of solar photovoltaic installations in future green energy systems ought to be significantly upgraded.
Solar cells are superior tools for producing renewable energy by using sunlight to induce electrical current for power. From the 1980s, they have been utilized to power homes, and their production cost and performance have enhanced considerably over the years.
A new study has shown that a magnetic uranium compound can exhibit powerful thermoelectric properties, thereby producing four times the transverse voltage from heat compared to the previous record in a cobalt-manganese-gallium compound.
Perhaps the most frustrating limitation of owning an all-electric car is how long it takes to fully charge the battery. For a Tesla, for example, it takes about 40 minutes to charge it to 80% capacity using the most powerful charging station.
Researchers from China have come up with a highly reliable thermal power generator that integrates triboelectric effect and thermoacoustic effect.
The cost of the rechargeable lithium-ion batteries used for phones, laptops, and cars has fallen dramatically over the last three decades, and has been a major driver of the rapid growth of those technologies. But attempting to quantify that cost decline has produced ambiguous and conflicting results that have hampered attempts to project the technology's future or devise useful policies and research priorities.
Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions. It contains carbon fibre that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially 'massless' energy storage in vehicles and other technology.
One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers at Linköping University, Sweden, have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for hydrogen gas production. The study has been published in the journal ACS Nano.
To understand the fundamental properties of an industrial solvent, chemists with the University of Cincinnati turned to a supercomputer.
