با افزایش مشکلات ناشی از مصرف غذاهای پرچرب، مصرف کنندگان تمایل به مصرف مواد غذایی کم چرب پیدا کرده اند. هدف از این پژوهش، بررسی امکان استفاده از نشاسته ذرت مومی به عنوان جایگزین چربی در خامه صبحانه جهت پیشگیری از بیماریهای قلبی می باشد. در این مطالعه از نشاسته ذرت مومی به میزان 1، 2 و 3% به دو شکل خام و اصلاح شده (سدیم اکتنیل سوکسینات) در خامه استفاده شد و میزان چربی خامه از 30% به 15% کاهش یاف...
Narrow bandgap PbS nanoparticles, which may expand the light absorption range to the near-infrared region, were deposited on TiO2 nanorod arrays by successive ionic layer adsorption and reaction method to make a photoanode for quantum dot-sensitized solar cells (QDSCs). The thicknesses of PbS nanoparticles were optimized to enhance the photovoltaic performance of PbS QDSCs. A uniform CdS layer ...
Quantum Confinement Effect and Photoenhancement of Photoluminescence of PbS and PbS/MnS Quantum Dots
We develop a composite photoanode by sensitizing TiO2 nanorod arrays with PbS quantum dots (QDs) and CdS QDs. Benefitted from additional introduced PbS QDs and CdS QDs onto TiO2, the absorption of the composite photoanodes are broaden from UV to visible region. The experimental results showed that the PbS sandwiched between TiO2 and CdS cannot only broad the absorption properties but also impro...
Using molecular modeling and known spatial structure of proteins, we have derived a universal 3D model of the orange carotenoid protein (OCP) and phycobilisome (PBS) interaction in the process of non-photochemical PBS quenching. The characteristic tip of the phycobilin domain of the core-membrane linker polypeptide (LCM) forms the attachment site on the PBS core surface for interaction with the...
Theoretical calculations based on density functional theory have found (PbS)(32) to be the smallest cubic cluster for which its inner (PbS)(4) core enjoys bulk-like coordination. Cubic (PbS)(32) is thus a "baby crystal," i.e., the smallest cluster, exhibiting sixfold coordination, that can be replicated to obtain the bulk crystal. The calculated dimensions of the (PbS)(32) cluster further provi...
