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...

Purpose – Prior research on underwriter reputation treats underwriters as the unit of analyzing, while the purpose of this paper is to analyze underwriter reputation effects after introducing discretion of underwriters’ employees. Specially, this paper investigates the damage on underwriter...

With the recent significant growth in the single-name credit default swap (CDS) market has come the need for accurate and computationally efficient models to value these instruments. While the model developed by Duffie, Pan, and Singleton (2000) can be used, the solution is numerical (solving a...
