A tool for “smart“ projection-photolithography

The NEEL Institute’s research work has created a vital need for fabrication "in house" of highly specialized microelectronics devices. These include silicon devices such as diodes, p-n and field-effect transistors, etc, for use in a wide variety of experiments. These devices are fabricated on demand by depositing different materials (e.g. metal leads, contacts, electrodes, ...) on the silicon wafer and performing oxidations and other processes, often in very complex geometric patterns.

New ceramics for domestic and cryogenic magnetic refrigeration

A continuously growing energy demand worldwide intensifies the need for development of new, high-performance energy conversion and storage technologies. A large part of energy consumption is due to cooling in the industrial sectors such as food conservation as well as air-conditioning for housing, buildings and vehicles. Hence, refrigeration appears as a major concern for the future involving both energy consumption and impact on the environment. To date, the energy for refrigeration comes primarily from fossil fuels which produce CO2, and it uses HFCs (hydrofluorocarbon type) gases for the classical gas-compression cycle. Both these gases pollute the environment. From this point of view, cooling based on using magnetocaloric ceramic oxides as the refrigerant material appears as a promising alternative. Full text.
