Synthesis of Novel Series of Coumarin Derivatives
Abstract: In a synthetic method similar to Knoevenagel reaction, 3-acetyl coumarin was prepared in the same way through a cyclization condensation reaction betweensalicylaldehyde and ethyl acetoacetate under basic condition using piperidine. Hence, 3-acetyl coumarin as a starting material was reacted with bromine in ether using a Lewis acid as a reactioncatalyst to produce the corresponding α–bromoaceyl cromen-2-one derivative. In application ofHantzsch synthesis, the reaction of α–bromoaceyl cromen-2-one with thioacetamide in ether …

Photo-degradation in Nanocrystalline Porous Silicon
Abstract: AbstractWe study the metastabilities created by light soaking (LS) in nanocrystalline porous silicon (nc-PSi), prepared by the electrochemical anodization technique. At first sight, these appear similar to the effects of LS observed in hydrogenated amorphous silicon (a-Si:H) prepared by PECVD (Plasma-enhanced chemical vapor deposition) method. In nc-PSi, the ESR (Electron Spin Resonance) and Raman results indicate the presence of a-Si:H. This suggests a-Si:H as a possible cause of photo-degradation in …
