4-t-Butylbenzylation of carboxylic acid for GC–MS analysis

open access: yesSN Applied Sciences, 2020
We report a 4-t-butylbenzyl derivatization for the analysis of carboxylic acids by GC–MS (EI). Carboxylic acids were analyzed as a 4-t-butylbenzyl ester after the derivatization with 4-t-butylbenzyl bromide. On the mass spectra of 4-t-butylbenzyl ester, [

Sustainable Spinning of Artificial Spider Silk Fibers with Excellent Toughness and Inherent Potential for Functionalization

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
A sustainable aqueous wet spinning method enables an efficient production of artificial spider silk fibers which show excellent extensibility and remarkable toughness. A highly specific and efficient biomolecular click reaction is employed to functionalize these fibers under mild conditions, which offers a promising method to construct multi‐functional

Edge-carboxylated Carbon Nanoflakes from Nitric Acid Oxidised Arc-discharge Material [PDF]

open access: yesarXiv, 2009
Carbon Nanoflakes (CNFs) with average diameters of about 30 nm have been prepared and isolated in bulk quantities by a single-step oxidation procedure using single-wall carbon nanotube arc-discharge material and nitric acid. The CNFs are predominately single, graphenic sheets containing a small number of internal defects.

2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration

open access: yesAdvanced Functional Materials, Volume 35, Issue 16, April 18, 2025.
Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...
