A novel synthesis method of partially crosslinking a polymer solution prior to casting, has been successfully developed for the preparation solvent-tolerant nanofiltration (STNF) membranes. STNF merges solvent resistant (SRNF) with aqueous nanofiltration. The feed consists mixture solvent(s) and water, requiring membrane both high water permeability stability. In this work, epoxy resins are pro...

The selective oxidation of alcohols with molecular oxygen was efficiently completed in high conversion and selectivity using copper-bisisoquinoline-based catalysts under mild reaction condition. The effects of various parameters such as reaction temperature, reaction time, oxidant, ligands, etc, were studied. Solvent effect has been as well studied in ionic liquids [bmim]PF6, [omim]BF4 and [hmi...

Electrochemically mediated atom transfer radical polymerization (eATRP) of styrene was studied in detail by using CuBr2/TPMA (TPMA = tris(2-pyridylmethyl)amine) as a catalyst. Redox properties various Cu(II) species were investigated CH3CN, dimethylformamide (DMF), and dimethyl sulfoxide (DMSO) both the absence presence 50% (v/v) styrene. This investigation together with preliminary eATRP exper...

Biocatalytic syntheses often require unfavorable conditions, which can adversely affect enzyme stability. Consequently, improving the stability of biocatalysts is needed, and this achieved by immobilization. In study, we aimed to compare soluble immobilized transaminases from different species. A cysteine in a consensus sequence was converted single aldehyde formylglycine-generating for directe...

Herein we reveal a straightforward supramolecular design for the H-bonding driven J-aggregation of an amine-substituted cNDI in aliphatic hydrocarbons. Transient absorption spectroscopy reveals sub-ps intramolecular electron transfer in isolated NDI molecules in a THF solution followed by a fast recombination process, while a remarkable extension of the excited state lifetime by more than one o...

In vitro drug metabolism studies during the early drug discovery stage are becoming increasingly important. With the increasing demand for high throughput and quick turnaround time for in vitro metabolism studies, however, careful examination of the results and proper design of the experiments are still crucial. In this communication, we report the identification and mechanism of formation of a...

In pursuit of designing novel chemical entities with antitumor and antimicrobial activities, 2-[(5-methyl-1,3-benzoxazol-2-yl)sulfanyl]acetohydrazidederivatives have been synthesized as a scaffold series amine derivatives, these analogs were on reductive amination solvent free condition. All the compounds assessed for antibacterial, antifungal, activities against standard strains. The 3a, 3b 3g...
