The creation of ternary multi-component crystals through the introduction of 18-crown-6 to direct the hydrogen-bonding motifs of the other molecular components was investigated for 3,5-dinitrobenzoic acid (3,5-dnba) with 4-aminobenzoic acid (4-aba). The creation of a binary complex between 18-crown-6...

In this study, we synthesized a novel multifunctional benzoxazine monomer (Coumarin-COOH BZ), possessing both coumarin and COOH groups, through the reaction of 4-methyl-7-hydroxycoumarin, 4-aminobenzoic acid, and paraformaldehyde in 1,4-dioxane, with the structure confirmed using ¹H and

Correlating PSf Support Physicochemical Properties with the Formation of Piperazine-Based Polyamide and Evaluating the Resultant Nanofiltration Membrane Performance.

Polymers (Basel). 2017 Oct 13;9(10). doi: 10.3390/polym9100505.

Membrane support properties influence the performance of thin-film composite nanofiltration membranes. We fabricated several polysulfone (PSf) supports. The physicochemical properties of PSf were altered by adding polyethylene glycol (PEG) of varying molecular weights (200⁻35,000 g/mol). This alteration facilitated the...

A surface functionalized with per-(6-amino-6-deoxy)-β-cyclodextrin for potential organic pollutant removal from water.

Carbohydr Polym. 2020 Apr 01;233:115865. doi: 10.1016/j.carbpol.2020.115865. Epub 2020 Jan 13.

In this work, we present a solid silicon substrate functionalized with modified β-cyclodextrin monolayers as an optimal surface for organic contaminant uptake. The inclusion and capture of three potential pollutants, 4-chlorophenoxyacetic acid, 4-aminobenzoic acid and phenylethylamine, were studied.

Materials (Basel). 2021 Jun 10;14(12). doi: 10.3390/ma14123198.

It was shown that carbon nonwoven fabrics obtained from polyacrylonitrile fibers (PAN) by thermal conversion may be modified on the surface in order to improve their biological compatibility and cellular response, which is particularly important in the regeneration of...

Identification of a previously unreported co-crystal form of acetazolamide: a combination of multiple experimental and virtual screening methods.

Phys Chem Chem Phys. 2020 Sep 23;22(36):20867-20879. doi: 10.1039/d0cp02700f.

In the search for new co-crystal forms, many studies only consider one method of co-crystallisation which may lead to incorrect results. In this work, we demonstrate the efficiency of applying multiple experimental and virtual screening methods for a more...
