The interaction of pure graphene nano sheet and Al-doped with SO2 pollutant gas molecules was examined by density functional theory (DFT). Adsorption energies the transferred Mulliken charge were calculated. Doping Al on improved adsorption electronic properties graphene. Dos plots HOMO-LUMO band gaps showed that semiconductor materials. results revealed sensitivity graphene-based materials enh...

In the paper, Ti-18Nb-5X (X = Mo and Sn) Ti-33Nb-2X Al, Sn, Fe Mo) alloys were investigated to evaluate effects of Mo, Sn doping different heat treatments on properties microstructures Ti-Nb-based alloys. The results show that Al decreased volume ?M in water-quenched Ti-33Nb-2Al alloy promoted formation ? phase furnace-cooled alloy. Fe-doping was proven stabilize phase. Sn-doping plays a compli...

ZnO, Al-doped ZnO (AZO), and Ga-doped ZnO (GZO) semiconductor thin films were deposited on glass substrates via a sol-gel spin-coating process for application in a photoconductive ultraviolet (UV) detector. The doping concentrations of Al and Ga were 1.0 at % in the precursor solutions. In this study, the microstructural features and the optical and electrical properties of sol-gel-derived ZnO,...

The structural analysis of GaN and Al x Ga1-x N/GaN heterostructures grown by metalorganic vapor phase epitaxy in the presence of Mn reveals how Mn affects the growth process and in particular, the incorporation of Al, the morphology of the surface, and the plastic relaxation of Al x Ga1-x N on GaN. Moreover, the doping with Mn promotes the formation of layered Al x Ga1-x N/GaN superlattice-lik...

doping is the use of drug for the purpose of improving performance in general and sports performance in particular. rejection or acceptance of the use of banned substances by athletes is determined by internal factors that are subjective and external or social. against this background, the present study examined social risk factors as determinants of intention (temptation) to use banned substan...

Phase II metabolism, usually known as conjugation reactions, generate metabolites that are, in most cases, biologically inactive and subsequently excreted in bile or urine. Androgenic and estrogenic sex steroids are mainly inactivated by sulfation or glucuronidation by the enzyme families’ sulfotransferases (SULTs) or uridine diphospho glucuronosyltransferases (UGTs). Genetic variations in UGTs...

The latest generation of photovoltaic cells are perovskite-based solar that can be fabricated through a simple and affordable process using high-efficiency power. This review also present zinc oxide (ZnO) adopted as an electron transport material (ETM) layer in the planar perovskitesolar due to its shynthesis excellent electrical properties. ZnO ETM conventional perovskite. Doping Aluminium (Al...

In this paper, the electrical and optical properties of undoped and in-situ doped amorphous SiC films are presented. The films are prepared by using mixture of methane (CH4) and silane (SiH4) as C and Si sources, phosphine (PH3) and diborane (B2H6) as doping gases. The bandgap, optical constant and absorption coefficient of the films are measured and a strong dependence on the layer composition...
