Non-fullerene-based organic solar cells (OSCs) have recently proven to perform with efficiencies above 18%. This is an important milestone for one of the most promising technologies in fields flexible and transparent/semitransparent photovoltaics. However, stability OSCs still a challenging issue meet industry requirements. Herein, several devices IT-4F:PM6 as active layer without 1,8-Diiodooct...

Combination therapy of antibiotics and nanoparticles can be used against multi drug resistant microorganisms. Nanoparticles (NPs) have been reported to show antimicrobial activity. The antimicrobial activities of doped ZnO nanoparticles (ZnO NPs) were studied against fungi, gram-positive and gram-negative bacteria using the standard microdilution method. The interaction between the nanoparticle...

nowadays, doping is an intricate dilemma for athletes. wrestling is the domestic, national and popular sport in iran. meanwhile, the prevalence of drug abuse in wrestling is high due to its power-demanding nature. so, we decided to evaluate the knowledge of club wrestlers of tehran about doping and their estimates of current prevalence in the country. in a cross sectional study, 426 wrestlers w...

Recently, TiO2 has been widely used as a photocatalyst for degradation of environmental pollutants. In the present study, the advantage of metal doping onto TiO2 for enhanced photocatalitic activity has been investigated. Copper-Titanium dioxide nanocomposites were prepared by the sol-gel method in the presence of Carboxy Methyl Cellulose (CMC), Pectin, and Poly Ethylene Glycol (PEG) as additiv...

introduction: today sport is one of the important social criterion and athletes are trying to be a champion. therefore, there is an increase in misuse of doping agents especially anabolic-androgenic steroid. this study was carried out to determine the prevalence of the doping agents' abuse among male bodybuilders' and to access their knowledge about their side effects in kermanshah gymnasiums i...

[Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)] (PEDOT:PSS, Baytron P) composite films were prepared under various conditions and their conductivities were studied by the current-sensing atomic force microscopy (CS-AFM) technique. Topographic and current images of pristine and additive-treated PEDOT:PSS as well as electrochemically synthesized PEDOT films were obtained in nanoscale us...

FeCo nanoparticles (4 ± 1 nm), encapsulated by SiO2, were synthesized with and without a 2% (atomic ratio) vanadium doping. The impact from the presence of vanadium, an additive often used in the bulk to alter both physical and mechanical properties, on the nanomagnetism was probed by element-specific X-ray spectroscopy and magnetometry techniques. While the nanostructure was unaffected by the ...
