Reed (1) isolated lipoic acid (LiA) from yeast and liver, and reported that this substance played an important role as one of the coenzymes in the oxidation of ƒ¿-keto acids. Sanadi (2, 3) reported that lipoamide (LiA-NH2), the amide of LiA, had greater activity than LiA as a coenzyme of ƒ¿-ketoglutraric dehy drogenase obtained from heart muscle. The authors (4) studied previously the serum lev...

Porous low-pressure membranes have been used as active in water treatment and support for thin-film composite desalination gas separation applications. In this article, microfiltration polysulfone (PSf)mixed-matrix (MMM) containing amine-functionalized graphene oxide (GO-NH2) were fabricated via a phase inversion process characterized using XPS, SEM, AFM, DMA, XRD, contact angle measurements. T...

Process intensification based on innovative coupling between membrane microfiltration and catalytic oxidation technologies has become a promising strategy for water treatment. Here, surface-nucleated metal–organic framework (MOF) was grown in situ to obtain an NH2-MIL-88B(Fe)-functionalized ceramic (NH2-MIL-88B(Fe)@CM), whose ability remove naproxen from matrices via the so-called electro-Fento...

Ammonium aminodiboranate ([NH4 ][BH3 NH2 BH3 ]) is a long-sought isomer of diammoniate of diborane ([NH3 BH2 NH3 ][BH4 ]) and ammonia borane (NH3 BH3 ) dimer. Our results show that [NH4 ][BH3 NH2 BH3 ] is stable in tetrahydrofuran at -18 °C and decomposes rapidly to NH3 BH2 NH2 BH3 and H2 at elevated temperatures. The decomposition pathway is dictated by the dihydrogen bonding between H(δ+) on ...

A number of substances affect the activity of protein kinase C. Among uncharged and zwitterionic compounds, those which activate protein kinase C also lower the bilayer to hexagonal phase transition temperature of dielaidoylphosphatidylethanolamine while substances which inhibit protein kinase C raise this transition temperature. Using this criteria, we have identified 3 beta-chloro-5-cholesten...

Bu çalışmada, organik atık kaynaklarından olan nar kabuğu, katalizör üretimi için ilk kez doğrudan destek malzemesi olarak kullanılmıştır. Amaç, yenilenebilir bir enerji kaynağı hidrojen kullanılabilecek metal içeren katalizörlerde kullanılacak maddesini kullanarak yüksek etkinliğe sahip sentezlemektir. Çalışma kapsamında toz haline getirilmiş kabuğu üzerine etanol eklenerek, daha sonra sırasıy...
