A controllable regioselective approach to achieve dipolar functionalization at the active sites (1,3-positions) and K-region (5,9-positions) of pyrene is demonstrated. Following this strategy, a set of dipolar 1,3-diphenyl-5,9-di(4-R-phenylethynyl)pyrenes were synthesized and systematically investig...

Abstract The adsorption properties of different Carbon allotropes (i.e., graphene, γ -graphyne, Mobius graphene, and R-graphyne) and their corresponding Boron (N) and Nitrogen (N) incorporated BCN nanostructures toward carbon monoxide (CO) gas are studied via density functional theory calculation. A...

Pepsin is a proteolytic enzyme used in the treatment of digestive disorders. In this study, we investigated the physicochemical properties of the tetradecyltrimethylammonium bromide (TTAB) and pepsin protein mixture in various sodium salt media within a temperature range of 300.55-320.55 K with 5 K ...

The syntheses of syn ‐[2. n ]metacyclophan‐1‐enes ( n = 5, 6, 8) in good yields using the McMurry cyclization of 1, n ‐bis(3‐formyl‐4‐methoxyphenyl)alkanes are reported. Conversion of syn ‐[2.6]‐ and [2.8]metacyclophan‐1‐enes to the corresponding highly strained syn ‐type [2.6]‐ and [2.8]metacycloph...

The Jashore district in Bangladesh is a major hub for vegetable cultivation and export. This study assesses the quality of vegetables from the region by determining concentrations of heavy metals (Fe, Zn, Cu, Pb, Cr, As, Cd) using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). I...

The chemoselective reduction is based on the reaction between Al either as powder or from the alloy and water which generates in situ hydrogen to effect the reduction of the targeted functional groups. Raney Ni-Al alloy with Al powder can reduce phenylacetylenes to the corresponding ethylbenzene (3)...
