Roughening

WebThe mechanical treatment of solar absorbers by rolling, surface roughening and polishing, and large scale texturing can significantly affect the absorption of solar radiation in the ultraviolet and visible range. In this study, the effect of a number of mechanical treatments was examined for a range of low cost absorber materials. WebIn general, wet etching is used for surface roughening to improve the light extraction of AlGaInP red LEDs. However, a structure fabricated by wet etching has limited height and shows a tiled cone shape after the etching process due to the AlGaInP crystal structure.

WebRoughening the surface with a sandpaper can be successfully used for many plastics, such as PEEK, nylon, polycarbonate and others. Below are the photos of PEEK coupons prepared for bonding. PEEK coupons before and after surface roughening with 60 grit sandpaper accompanied by a magnified image of the partially roughened surface. WebThe surface-enhanced Raman spectroscopy (SERS) of polypyrrole (PPy) can be obtained by roughening the Au substrate with electrochemical oxidation-reduction cycle (ORC) before PPy deposition. The optimum condition for obtaining SERS effect is based on the strongest peak of C=C backbone stretching of PPy located at ca. 1600 cm -1 shown in SERS. i can watch this movie any day https://caalmaria.com
