Researchers at have designed and fabricated the world's smallest electro-optic modulator, which could mean major reductions in energy used by data centers and supercomputers.
Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion, according to a team of Penn State researchers.
University of Washington researchers have published the first major assessment of small hydropower dams around the world -- including their potential for growth -- and highlight the incredibly variability in how dams of varying sizes are categorized, regulated and studied.
Researchers at Berkeley Lab discovered that a form of perovskite, one of the hottest materials in solar research currently due to its high conversion efficiency, works surprisingly well as a stable and photoactive semiconductor material that can be reversibly switched between a transparent state and a non-transparent state, without degrading its electronic properties.
Rutgers scientists have found the 'Legos of life' -- four core chemical structures that can be stacked together to build the myriad proteins inside every organism -- after smashing and dissecting nearly 10,000 proteins to understand their component parts. The four building blocks make energy available for humans and all other living organisms, according to a study published online today in the Proceedings of the National Academy of Sciences.
Advancements in a fuel cell technology powered by solid carbon could make electricity generation from coal and biomass cleaner and more efficient, according to a paper published this week. Innovations in the anode, the electrolyte and the fuel allow the fuel cell to utilize more carbon, operate at lower temperatures and show higher maximum power densities than earlier direct carbon fuel cells (DCFCs). The results appear in this week's edition of Advanced Materials.
A team of scientists from Siberian Federal University (SFU) and their colleagues from Novosibirsk and the Netherlands modeled the process of coal burning in HPP boilers and found out which type of fuel produced less harmful emissions. The study was published in Fuel journal.
Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.
Plastics are often derived from petroleum, contributing to reliance on fossil fuels and driving harmful greenhouse gas emissions. To change that, Great Lakes Bioenergy Research Center (GLBRC) scientists are trying to take the pliable nature of plastic in another direction, developing new and renewable ways of creating plastics from biomass.
The nominal cell operating life of perovskite solar cells is strongly influenced by their inner architecture.This was shown by two scientists at the Helmholtz-Zentrum Berlin and the Technical University of Munich. They combined experiments with numerical simulations in order to explain this observation.
