Hafnium carbide (HfC) is a promising materials for high-temperature heat exchangers due to its high melting point (4170 K). Nevertheless, its fast oxidation into fragile hafnia prevents it from being used for open-air solar receivers. The incorporati

Two solar missions are designed to plunge into the solar corona, and respectively get as close as 8.5 and 3 Rs (solar radii) from the Sun’s surface. Heat shields will protect the payloads within their umbra from the thermal radiation and solar wind

Experience with polarized targets and achieving of very low temperatures gave rise to the idea of using a new technique based on dissolving 3He in 4He to create a frozen spin polarized target. The short history of the development of such proton and d
