A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.

Here, the possibility of existence nitro-graphene derivatives with undisturbed graphene backbone is considered. Based on first-principles calculation, it shown that while NO $$_2$$ unable to form a covalent bond bare graphene, becomes possible in some structures hydrogenated graphane, fluorographene, and oxide. This paper presents, among others, an analysis surrounding influence C-NO strength. ...

The present study describes the effect of NCO/OH and triol/diol ratios on the mechanical properties of Nitro functionalized Hydroxyl-terminated polybutadiene (Nitro-HTPB) elastomers. The progress of the cure reaction of Nitro-HTPB and toluene diisocyanate (TDI) is evaluated by following up the variations in the IR absorption bands of the NCO stretching and the CO ...

Abstract In this work, we used the design strategy “doped nonpolar polymers” and synthesized polyurethane elastomers (PUEs) by doping with highly polar aromatic molecules such as benzoic acid (BA), 4(para)-nitro-benzoic (PNBA), 3, 5-di-nitro-benzoic (3, 5-DNBA) using solution casting method. The effect of each molecule in three different weight percentages 2%, 4%, 6% on electrical thermo-mechan...

Nitro compounds are an important class of organic molecules with broad application in synthesis, medicinal chemistry, and materials science. Among the variety methodologies available for their direct oxidation primary amines represents attractive alternative route. Efforts towards development oxidative procedures synthesis nitro derivatives have spanned over past decades, leading to a wide prot...

Background & Aims of the Study: One of the most carcinogenic and toxic pollutants is p-Nitro Cresol. In this study, the degradation and mineralization of p-Nitro Cresol in aqueous solution were investigated by Fenton process in a batch reactor. Materials & Methods: This study is an experimental research on a laboratory scale. The study executed on synthetic wastewater hav...

A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...

A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...
