Abstract Photo-redox catalysis has emerged as a new generation of biochemical protocols in proximity labeling, noninvasive therapy, ultrafast activation. However, the well-developed photocatalysts cannot simultaneously p...

Regulation of hot spots exhibits excellent potential in many applications including nanolasers, energy harvesting, sensing, and subwavelength imaging. Here, hat-shaped hierarchical nanostructures with different space cur...

Abstract FLPClusters, which are structurally precise metal clusters incorporating Frustrated Lewis Pairs (FLPs), represent a promising class of FLP catalysts. Although FLPClusters have emerged only recently, their precis...

The research was aimed to use the residual asphaltic materials taken from northern refinery in the preparation of activated carbon by oxidation with V O5 in the presence of a stream of air for 3hrs at 350°C temp, .The r...

A gold nanoparticle solution was prepared by adding sodium borohydride (NaBH4), trisodium citrate dihydrate (C6H5Na3O7⋅2H2O), cetyltrimethyl ammonium bromide (CTAB,(C16H33)N(CH3)3Br), ascorbic acid (C6H8O6), and potass...

In this study, we present an effective chemo-enzymatic method for synthesizing di- and tetra-carboxyl–functionalized poly(ethylene glycol)s (PEGs) using Candida antarctica lipase B (CALB). PEG-diacid was synthesized th...

The growing demand for sustainable chemical processes has spurred interest in enzymatic synthesis, particularly for valuable compounds like ethyl lactate. Traditional chemical methods often suffer from drawbacks, highlig...

Illumination of noble metal nanostructures by electromagnetic radiation induces coherent oscillations of conductive electrons on their surfaces. These coherent oscillations of electrons, also known as localized surface p...

Abstract The Schiff’s Bases (N-arylidene benzylamines) (1-29) have been alkylated with different alkyl halides by applying solid-liquid phase-transfer catalysis system (solid K2CO3, CH3CN, TBAB). The products were iden...

Room temperature ionic liquids (RTILs) have been widely used as (co)solvents in several catalytic processes modifying, in most of the cases, the catalyst activity and/or the selectivity for the studied reactions. However...
