The mechanical properties of chemically vapor deposited SiC warrant CVD as a potential fabrication process for gas turbine applications. A look at some of the key factors involved.

In recent decades, horizontal integration by product line and productive risk diversification has been extensively employed by Western business. Those primary metals producers who also engaged in careful vertical integration experienced another type of risk dilution over the same time period. This report examines and assesses commercial strategies among aluminum producers.

Photovoltaic perovskites are very attractive candidates as absorber layers because of their very interesting properties. In the present work, we have two parts: first, we prepared powders of the perovskites MAPbBr3, MAPbI3, and MAPbCl3, with the aim of maximizing their purity, and then we deposited thin films using these powders previously prepared by the one-step spin-coating method. The anti-solvent used was under the same ambient deposition conditions. We concluded with a series of characterizations such as X-ray diffraction, scanning electron microscopy, and UV–visible absorption to better appreciate the quality of the films produced. The crystalline structures of the films, their surface morphology, and their optical properties from the characterizations show that we have succeeded in producing film samples suitable for photovoltaics.
