Synthetic chemists could soon see a new addition to the catalysts available to them. Researchers at INAC recently showed that core-shell nanocrystals (cadmium selenide-zinc sulfide) are effective catalysts. First, they are active in water, under visible light. Even better, they can transfer several electrons at once, creating complex reactions. The researchers have successfully stabilized these […] >>

A Ph.D. candidate at Leti has developed an analog-digital converter and a signal filtering architecture that are setting new energy efficiency records. The innovation leverages 28 nm FD-SOI and a new, event-driven, signal processing mode, which means the systems are activated by the signal’s behavior—such as exceeding a given intensity threshold—rather than by a clock […] >>

UV LEDs produced using the semiconductor material aluminum gallium nitride (AlGaN) in thin layers perform poorly in the brightness and lifespan departments. Researchers on a joint INAC-CNRS team wondered what would happen if they used the material in nanowire form. And, if their early results are any indication, the use of nanowires could improve UV […] >>

A biobattery capable of producing energy from ocean and lake sediments would be a wonderful invention! But for it to become a reality, scientists first have to figure out how to extract in real time a source of energy whose characteristics vary on a scale of one to ten depending on the environment. Leti has […] >>

A 3D multicore circuit developed by two teams of researchers from Leti recently set a new global state of the art. The research and development work, conducted under a project spearheaded by IRT Nanoelec, resulted in the development of the INTACT circuit, which offers five times more processing power and double the energy efficiency of […] >>
