Solar panels produce renewable energy, of course. However, like any manufactured product, solar cells also produce waste. In fact, 40% of the ultra-pure silicon used to make photovoltaic cells goes to waste during the diamond-wire cutting process. Startup Rosi was created in late 2017 to reduce this massive waste. The company is combining a chemical […] >>

Germanium produced with very few impurities is thought to be compatible with ballistic (impact-free) transport of electrons or holes. In addition, theoretically, holes offer strong spin-orbit coupling. Researchers from INAC working with colleagues from the UK and the Netherlands* recently demonstrated these two theoretical properties in the lab on a quantum electronic system built specifically […] >>

Can automotive switches be controlled by MPC*-type rules despite the switches’ limited processing power? EFI Automotive and Leti recently kicked off a research project to find out. If they are successful, EFI Automotive’s future switches will deliver levels of performance never before seen on the market, whether it is in terms of speed, energy consumption, […] >>

It turns out that electrical insulator yttrium iron garnet (YIG) is also a great conductor of spin current. The material also possesses non-linear transport properties when the current exceeds a certain threshold. Researchers from INAC worked with three other teams* to demonstrate the material’s capabilities, measuring spin conductance between two platinum wires on a thin […] >>

Artificial photosynthesis systems present a major shortcoming: Their photosensitizer delivers electrons one by one while the catalyst uses them two by two. A team of researchers from Grenoble and Germany* recently found a solution to this problem. They developed a ruthenium-based photosensitizer that stores two electrons and two protons reversibly, similar to the plastoquinones in […] >>
