Environmental degradation and energy shortage are the two biggest problems facing world right now. Because of limited supply non-renewable sources, production environment-friendly its storage has gained significant importance. Pseudocapacitors have lately caught interest specialists due to their greater energy/power density prolonged cycle life. In this work, binding-free SnTe/SnSe (STSS) electrodes deposited onto Ni foam (NF) as conductive substrate been developed by a facile hydrothermal...
Monoclinic bismuth oxide α-Bi2O3 nanoparticles were synthesized starting from a mixture of oxalate complexes Bi(C2O4)OH and Bi2(C2O4)3·xH2O obtained by direct solid-state reaction between nitrate salt oxalic acid. The precursors studied thermal gravimetric analysis (TGA) characterized Fourier transform infrared spectroscopy (FTIR). After heat treatment the precursors, was X-ray diffraction (XRD) transmission electron microscopy (TEM). These show low efficiency in photodegradation under UV...
The inhibition of L-Cysteine Methyl Ester Hydrochloride (L-CMEH) on the corrosion copper in 2M HNO3, was studied by gravimetric method, range temperatures from 303 to 343 K. Results obtained show that L-CMEH acts as inhibitor for HNO3 solution. efficiency found increase with concentration but decreased temperature. assumed occur via adsorption metal surface. onto surface follow Langmuir isotherm. Both kinetic parameters (activation energy, pre-exponential factor, enthalpy activation and...
The present paper illustrates the investigation of two novel ecological triazole derivative corrosion inhibitors, namely ethyl 2-(4-phenyl-1<italic>H</italic>-1,2,3-triazol-1-yl) acetate [Tria-CO<sub>2</sub>Et], and acetohydrazide [Tria-CONHNH<sub>2</sub>].
In this work, two compounds of isonicotinohydrazide organic class, namely (E)-N′-(1-(4-(dimethylamino)phenyl)ethylidene) (MAPEI) and (Z)-N′-(2-oxo-2, 3-dihydro-1H-inden-1-ylidene) (OHEI) were synthesized evaluated for corrosion protection N80 steel in a concentrated acidic medium (15 wt.% HCl) at temperature 303 K. The weight loss method (gravimetric method) electrochemical techniques, i.e., impedance spectroscopy (EIS) potentiodynamic polarization curves (PPC), used to evaluate the...
Nowadays, waste discharge and contaminants in drinking water have emerged as a significant global problem. Therefore, it is necessary to remove these pollutants from the photocatalysis best technique for this purpose. The co-precipitation was employed produce NiMn2O4 ZnMn2O4 photocatalyst containing NiMn2O4/ZnMn2O4 heterostructure nanocomposite. Various analytical techniques been ascribed examine physical, morphological optical features of fabricated catalysts. XRD diffraction peak patterns...
Nitrogen heterocyclic rings and sulfonamides have attracted attention of several researchers. A series regioselective imidazole-based mono- bis-1,4-disubstituted-1,2,3-triazole-sulfonamide conjugates 4a–f 6a–f were designed synthesized. The first step in the synthesis was a propargylation presence appropriate basic catalyst (Et3N and/or K2CO3) to afford corresponding mono-2 bis-propargylated imidazoles 5. Second, ligation terminal C≡C bond bis alkynes 5 azide building blocks sulfa drugs 3a–f...
A library of novel regioselective 1,4-di and 1,4,5-trisubstituted-1,2,3-triazole based benzothiazole-piperazine conjugates were designed synthesized using the click synthesis approach in presence absence Cu(I) catalyst. Some these 1,2,3-triazole hybrids possess their structures different heterocyclic scaffold including 1,2,4-triazole, benzothiazole, isatin and/or benzimidazole. The newly assessed for antiproliferative inhibition potency against four selected human cancer cell lines (MCF7,...
3-(4-hydroxybutyl)-1-phenethyl-1H-imidazol-3-ium chloride ([HB-Imid] Cl), and 3-(2-chlorobenzyl)-1-phenethyl-1H-imidazol-3-ium ([CB-Imid] Cl) were investigated as corrosion inhibitors for mild steel in 1.0 M hydrochloric acid solution. Electrochemical techniques (PDP EIS) performed experimental studies while DFT at B3LYP 6-311G (df,pd), molecular dynamic simulation used theoretical approach. PDP experiments revealed that the studied ionic liquids (ILs) behaved mixture type inhibitors. EIS...
Currently, the global problem of poisonous and nondegradable organic water pollutants cannot be ignored. Heterogeneous photocatalysis is an advanced oxidation process (AOP) that uses semiconducting materials as a catalyst to clean water. Nanosize semiconductor photocatalysts are well recognized for their practical cost‐effective way cleaning up environmental pollution when exposed visible light. Herein, simple hydrothermal approach used create MnS/rGO nanocomposite degradation aromatic dyes...
