a flame detector controls a relay through an amplifier, the relay having at least one pair of contacts controlling a solid state switch which unshunts an impedance in series with the relay coil on operation of the relay to reduce the power dissipation. Power is supplied to a boiler control ...
slow gas molecules condensing at the liquid surface and fast liquid molecules escaping into the gas. Anequilibriumstate is reached in any closed system, so that the number of exchanges in either direction is the same. Because the kinetic energy of particles in the liquid state can be defined ...
Solid-state chemistry is the study of the preparation, structure and properties of solid materials. Latest Research and Reviews Integration of ordered porous materials for targeted three-component gas separation Separation of multi-component mixtures is an extremely difficult task. Pore integration strategy...

Single-crystal to single-crystal solid/gas reactivity and catalysis starting from the precursor sigma-alkane complex [Rh(Cy2PCH2CH2PCy2)(η2η2-NBA)][BArF4] (NBA = norbornane; ArF = 3,5-(CF3)2C6H3) is reported. By adding ethene, propene and 1-butene to this precursor in solid/...
We have developed an all-solid-state 5-kHz Ti:sapphire laser system, which produces 22-fs, 0.2-TW pulses. An average power of 22.2 W is the highest ever obtained in ultrashort laser sources. The serious thermal lensing due to high power pumping in a small area of the Ti:sapphire cryst...
