Silver nanoparticles (AgNPs) loaded on the cotton fiber can endow with good antibacterial activity, but AgNPs surface of will leach out increase washing times, which not only greatly reduce properties fiber, also cause pollution to environment. In this paper, carboxyl groups were introduced into by three methods, namely selective oxidation, butane tetracarboxylic acid (BTCA) grafting and polyac...

In view of the challenges posed by nature expansive soil to structural stability which makes it necessary in some cases improve soils before structures can be placed on them, there is a need investigate modern trends ground improvement techniques order determine their reliability. This study thus aimed at using reliability based approach analyze use polyvinyl alcohol (PVA) combination with 1,2,...

Two new diastereomeric chiral stationary phases (CSPs) based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid as a chiral tethering group and a Π-basic chiral unit such as (R)-1-(1-naphthyl)ethylamine (CSP 1) or (S)-1-(1-naphthyl)ethylamine (CSP 2) were prepared. The two CSPs were applied to the enantiomeric separation of N-(3,5-dinitrobenzoyl)-1-phenylalkylamines and N-(3,5-dinitrobenzoyl)-α...

Uniform and crystalline nanofibers of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA), an insoluble organic semiconducting molecule, have been achieved by self-assembling the molecules using chemical reaction mediated conversion of an appropriately designed soluble precursor, perylene tetracarboxylic acid (PTCA) using carbodiimide chemistry.

The solid-state emission properties of bifluorene–tetracarboxylic acid were reported and rationalised on the basis fluorene torsional dynamics by SC-XRD DFT calculations.

Experimental Section Solvents and reagents were purchased from Merck and used as received. 1,6,7,12Tetrachloroperylene-3,4:9,10-tetracarboxylic acid bisanhydride was obtained from BASF. N,N'-Didodecylperylene-3,4:9,10-tetracarboxylic acid bisimide 2 was synthesized according to the literature. NMR spectra were recorded on a Bruker DRX 400 spectrometer using the proton signal of TMS as internal ...
