The poor thermal performance of prefabricated house roof in severe cold area results in the increase of heating energy consumption and uncomfortable indoor thermal environment. Roof energy-saving retrofits are necessary, and the specific retrofit measures are investigated from the perspective of...

Metal- and halide-free catalyst DABCO·HSac, i.e. the binary adduct of 1,4-diazabicyclo[2.2.2]octane (DABCO) and saccharin (HSac), in an ionic pair structure of DABCO-H⁺·Sac⁻ is shown mild and efficient in promoting the cycloaddition of CO 2 into epoxides (CCE) reactions. Under...

Cycloaddition of CO2 into epoxides (CCE) reaction was the few chemical processes viable commercially in valorizations of carbon dioxide. The produced cyclic carbonate was valuable in electrolyte of lithium batteries and so on, however, halide anion was monopoly as cocatalyst in catalytic CCE...

In this paper, CuO/MnO2 nanocomposites were successfully fabricated by simple and economical electrodeposition and successive ionic layer adsorption and reaction (SILAR) method as electrode materials for supercapacitors (SCs). Spherical and wheat-shaped CuO nanomaterials were obtained by...

We use transactions data to explore the magnet effects of price limit rules on the Shanghai Stock Exchange (SHSE). When limit hits are imminent, stock prices are found to approach the price limits at faster rates, with higher trading intensity and larger price variation, supporting the magnet...

A two stage Rankine cycle for power generation is presented in this paper. It is made of a water steam Rankine cycle and an Organic Rankine bottoming Cycle. By using an organic working fluid with higher density than water, it is possible to reduce the installation size and to use an air-cooled...
