Introduction: Phenolic compounds and flavonoids have several biological properties, such as antioxidant properties, trapping free radicals, and anti-inflammatory properties. Different solvents have different capabilities in extracting phenolic materials and antioxidant properties. This study aimed to investigate and compare the different plants in the south of Iran regarding phenolic content an...
The aim of the study was to investigate process electrostatic fabrication cellulose acetate (CA) nanofibers containing methylene blue (MB) as a photosensitizer. electrical, physicochemical, and biocidal properties prepared material were given. CA by electrospinning method using solvent mixture acetone distilled water (9:1 vv?1) different concentrations (i.e., 10–21%). Additionally, implemented ...
Abstract In general, the electro-spinning of lignin requires it to be functionalised and/or blended with synthetic or natural polymers. This paper reports on use solvent fractionated lignin-lignin blend electro-spin BioChoice softwood Kraft lignin. The consisted acetone-soluble and ethanol-soluble in a binary acetone DMSO. Solvent fractionation was used purify where ash content reduced soluble ...
A greener solvent acetone is applied to replace DMF and NMP for depositing high-quality perovskite thin films through the formation of an acetone–MAI–PbI 2 intermediate phase.
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
The present study was carried out to investigate the association of C/T single nucleotide polymorphism(SNP)in exon 5 of stearoyl-CoA desaturase 1 (SCD1) gene and A/C SNP in the 3' untranslated region of oxidized low density lipoprotein receptor 1 (OLR1)gene with milk production traits in Iranian Holstein dairy Cattle. The blood samples of 153 (for OLR1) and 308 (for SCD1) dairy cattle from thre...
Polycyclic aromatic hydrocarbons (PAHs) are a major class of organic hydrocarbons with high molecular weight that originate from both natural and anthropogenic sources. Sixteen PAHs are included in the U.S Environmental Protection agency list of priority pollutants due to their mutagenic, carcinogenic, toxic and teratogenic properties. In this study, the development and optimization of a simpli...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
A hybrid quantum mechanical and molecular mechanical potential is used in Monte Carlo simulations to examine the solvent effects on the electronic excitation energy of the n → π(*) transition of acetone in ambient and supercritical water fluid, in which the temperature is in the range of 25-500 °C with pressures of 1-2763 atm. In the present study, the acetone molecule is described by the AM1 H...
