We present a systematic study of the Lehmann rotation of cholesteric droplets subjected to a temperature gradient when the concentration of chiral molecules is changed. The liquid crystal chosen is an eutectic mixture of 8CB and 8OCB doped with a small amount of the chiral molecule R811. The angular velocity of the droplets strongly depend on their size and on the concentration of chiral molecu...

Directional solidification of metal-gas eutectic (Gasar) is a novel process for making regular porous metals. This process is based on a solid-gas eutectic reaction involving a gaseous medium and a metal or a ceramic phase, and allows an easy control of the porosity, such as its pore size, pore orientation and morphology in a wide range by properly adjusting its melting and solidification condi...

Today`s telecommunications/datacom industry is coping with its own technical challenges in processing capabilities as it juggles demands for greater electrical performance and reduced sizes. Particularly hot in technical slate are automatic eutectic attachment techniques, which are desirable for high-performance and high-capacity die attach applications. Actually, the eutectic die attach techni...
