Six derivatives of novel triazoles were produced from some substituted benzoic acid with thiocarbazide via method grinding. The Chemicals described 1HNMR, IR, and 13CNMR spectra examinations. Produced C2H3N3 examined assessed as reducing corrosion in 0.5 M HCl for low-C steel utilizing procedure losing weight. It was noticed that such chemicals had an encouraging act reducer counter to mild sol...
abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
Ethylammonium Propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1HNMR and IR. This ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °C. This IonicLiquid is able to dissolve most of organic solvents due to the hydrogen interaction between IonicLiquid and th...
Treatment of 7-chloro-1-phenylpyrimido[4,5-e][1,3,4]thiadiazines with hydrazine in boiling ethanol gave corresponding7-hydrazinyl derivatives. Diazotization of the latter compounds acheived a mixture of 5H-tetrazolo[1',5':1,2]pyrimido[4,5-e][1,3,4]thiadiazine and 9H-tetrazolo[5',1':2,3]pyrimido[4,5-e][1,3,4]thiadiazines. Ratio of these two group of products determined by 1HNMR studies and no si...
In this work, novel mitochondrial and CD44 receptor dual-targeting redox-sensitive multifunctional nanoparticles (micelles) based on oligomeric hyaluronic acid (oHA) were proposed. The amphiphilic nanocarrier was prepared by (5-carboxypentyl)triphenylphosphonium bromide (TPP), oligomeric hyaluronic acid (oHA), disulfide bond, and curcumin (Cur), named as TPP-oHA-S-S-Cur. The TPP targeted the mi...
A novel dendritic star-copolymer, generation 3 poly(propylene thiophenoimine) (G3PPT)-co-poly(3-hexylthiophene) (P3HT) star co-polymer on gold electrode (i.e., Au|G3PPT-co-P3HT) was used as a sensor system for the determination of phenanthrene (PHE). The G3PPT-co-P3HT star co-polymer was synthesized via in situ electrochemical co-polymerization of generation 3 poly (propylene thiophenoimine) an...
The rapid and continuous progress in trace analysis of metals is associated with development of several new techniques such as spectrophotometry. Thiosemicarbazones have been used as chromogenic reagents in spectrophotometric determination of metals. In this study the synthesis and characterization of pyridoxal thiosemicarbazone (PDT) and 2-acetyl pyridine thiosemicarbazone (2-APT) using IR, MS...
Larson-Meyer, D. Enette, Bradley R. Newcomer, and Gary R. Hunter. Influence of endurance running and recovery diet on intramyocellular lipid content in women: a 1HNMR study. Am J Physiol Endocrinol Metab 282: E95–E106, 2002.—Using a randomly assigned crossover design, we evaluated the change in intramyocellular lipid stores (IMCL) from baseline after a 2-h treadmill run [67% of maximal oxygen u...
