Crack-free inverse opals exhibit a sharply defined threshold wettability for infiltration that has enabled their use as colourimetric indicators for liquid identification. Here we demonstrate direct and continuous photo-tuning of this wetting threshold in inverse opals whose surfaces are functionalized with a polymer doped with azobenzene chromophores.
Active pharmaceutical ingredients (APIs) can be assured to safe and effective with the help of stability-indicating procedures. An accurate comparison comprising utilization capillary zone electrophoresis (CZE) ultra-performance liquid chromatography (UPLC) for sensitive measurement ciprofloxacin (CPF) in presence its major photo-degradation product was conducted. The CZE UPLC working condition...
selective desulfurization of thiocarbonyls to carbonyls thioacetalization of aldehydes and ketones a useful reagent system for the dethioacetalization reactions
A NADPH substitute where the nicotinamide moiety is replaced by a chromophoric unit having much larger two-photon absorption cross-section and able to transfer electrons to flavins only upon excitation is described as an effective two-photon nanotrigger for selective photo-activation of electron transfer in bioreductive processes.
Abstract Mixed halide perovskites have attracted great interest for applications in solar cells, light emitting diodes and other optoelectronic devices due to their tunability of optical properties. However, these mixtures tend undergo de-mixing into separate phases when exposed (photo de-mixing), which compromises operational reliability devices. Several models been proposed elucidate the orig...
بهره برداری های بی رویه و چند جانبه از منابع معدنی و گیاهی و طبیعت سلسله جبال زاگرس، لطمات جبران ناپذیری به این زیستگاه ها وارد کرده است. با توجه به وجود فلور و فون غنی منطقه دنا، و توان و استعداد تخریب و فرسایش بالای این ناحیه به حفاظت و حراست از این منابع با ارزش توسط مسئولین منطقه نیاز می باشد و لازمه این حراست داشتن شناخت و اطلاعات کافی از وضعیت موجود و توان منطقه می باشد. شهرستان سمیرم واق...
