Transmission Geometry

An inexpensive capillary furnace has been developed for variable-temperature X-ray diffraction in transmission geometry of air-stable liquid crystals and other materials. It offers temperature control with fluctuations of less than ±1 K in the range of interest for these samples, from room temperature to near 573 K. Phases can be accessed through heating or cooling with no significant overshooting of the target temperature. The furnace is designed to fit on a classical goniometer, and can be controlled by any standard temperature controller. The simple design of this furnace means that it is both inexpensive to build and easy to operate.

Heating Energy Consumption

With the improvement of peoples living standard, decreasing of heating energy consumption is significant for building energy saving. The practice of household heat metering system can accelerate the promotion process of household metering, regulation and control. This can improve the indoor thermal comfort of residential building and energy saving awareness, so that it will promote the development of building energy saving and emission reduction. In this paper, room temperature control and household heat metering system are optimally designed, and intelligent on-off valve regulation is developed to control room temperature. The results show that heat waste is greatly reduced by using household heat metering system and a better thermal comfort is obtained.

Solvent Free Synthesis

An enantioselective 1,4-conjugate addition of nitromethane to β-silyl α,β-unsaturated carbonyl compounds catalyzed by bifunctional squaramide catalysts has been developed. This methodology offers both enantiomers of β-silyl nitroalkanes in good to excellent yields (up to 92%) and enantioselectivities (up to 97.5% ee) under solvent-free conditions at room temperature. Control experiments reveal that the presence of a β-silyl group in the enones is crucial for high reactivity under the optimized reaction conditions.
