4-Amino-5-(1-hydroxy-ethyl)-2,4-dihydro-[1,2,4]triazole-3-thione was synthesized and characterized by single crystal x-ray analysis. Thermodynamic calculations at B3LYP/6-31+G(d,p) level of theory proved that 4-Amino-5-(1-hydroxy-ethyl)-2,4-dihydro-[1,2,4]triazole-3-thione is the most stable tau...

The amino-modified covalent organic framework (NH2@COF) was synthesized via the thiol-ene click reaction of vinyl covalent organic framework (COF) with 4-aminobenzenethiol. The introduction of amino groups can interact with the anionic headgroup of carboxylic acid pesticides. Moreover, ample hyd...

Peroxisome proliferators are generally known as activators of fatty acid β-oxidation which is one of degradation pathways. However, since it is unknown whether peroxisome proliferators have an effect on biosynthesis of fatty acid or not, we commenced to study if acetyl-CoA carboxylase, the rate...

The purpose of our research was to obtain and characterize Cu(II), Co(II) and Ni(II) complexes with herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA). The structural characterization of compounds in their powder form was based on various laboratory as well as synchrotron X-ray spectroscopic m...

A multi-walled carbon nanotube (MWCNT) paste electrode modified with zinc layered hydroxide-2(3-chlorophenoxy)propionate (ZLH-CPPA) was evaluated for the voltammetric determination of Cu(II). The optimum conditions were obtained at 2.5% (w/w) ZLH-CPPA: MWCNT, 4 × 10−3 M CH3COONa, pH 2.5 (with a...
