Resorcinol and 4-n-butyl resorcinol have been used to improve skin health. However, these two compounds were unstable due to the oxidation process. Lipid nanoparticle formulation strategies were reported as the solution to overcome the stability problem f... see more

Ab initio calculations have been performed in order to investigate the conformational characteristics of p-(nitro)methoxycalix[4]arene and p-(tert-butyl)methoxycalix[4]arene. The structures of four types (cone, partial cone, 1,2-alternate and 1,3-alternat... see more

Lipid nanoparticles, one of nanoparticle technology results has been developed both as a drug delivery system and as a research object. Complex lipid nanoparticle, in the drug delivery system development, has an advantage due to its less toxicity. It is i... see more

Decomposition of triphenylbismuth dicrotonate in diffused light in bensene in the presence of spin trap of C-phenyl-N-tert-butylnitrone leads to formation of phenyl radicals which are registered as the adduct PhCH(Ph)N(O•)Bu-t.Triphenylbismuth dicrotonate... see more

The synthesis of 4-tert-butylbenzoyl amoxicillin has been done by reacting amoxicillin with 4-tert-butylbenzoyl chloride. The product was characterized using proton and carbon-13 spectrometry. Antibacterial activity of 4-tert-butylbenzoyl amoxicillin agai... see more

The nucleophilic substitution reaction is one of the important and commonly studied in organic chemistry reaction. The mechanism of how the reaction actually takes place and what species play a role in the system so that the product is formed is reviewed ... see more

The paper is devoted to preparation and study of the transformations of novel multifunctional fluorinated synthetic building blocks – alkyl N-(3-nitro-1,1,1-trifluoropropan-2-yl) carbamates. In order to obtain them in high yields the aza-Henry reaction of... see more

The study on the transport behavior of Cr(III), Cd(II), Pb(II), and Ag(I) through bulk liquid membrane using p-tert-butylcalix[4]arene-tetradiethylacetamide as ions carrier has been conducted. The aims of this work are to determine the optimum condition, ... see more

The research on transport of Cr3+, Cd2+, Pb2+, and Ag+ through bulk liquid membrane using p-tert-butylcalix[4]arene-tetracarboxylic acid as ions carrier has been conducted. The aims of this research were to determine optimum condition, efficiency, and sel... see more
