Boron-doped ZnO (BZO) films deposited by metal organic chemical vapor deposition (MOCVD) generally act as transparent conductive oxide films in hydrogenated amorphous silicon (a-Si:H) solar cells and exhibit a high external quantum efficiency (EQE) performance in the short-wavelength region....

As urban construction has been developing rapidly in China, urban heating load has been increasing continually. Heating capacity of the existed primary heating network (PHN) cannot meet district heating requirements of most metropolises in northern China. A new type of ejector heat exchanger...

In this work, an Al2O3-coated SiC foam monolith was used as the support of a Ni-based catalyst, which was applied for coupling partial oxidation and steaming reforming of methane to produce syngas or hydrogen. This monolithic catalyst showed excellent structural stability in a 900h endurance...
