Abstract Glassy samples from the undoped ternary system Na 2 O–ZnO–P O 5 in combination with other same doped variable amounts of MoO 3 (0.25, 0.5, or 1 gm/batch) were successfully melted under ordinary, oxidizing, reducing conditions followed by annealing. Fourier transform infrared spectrophotometric measurements optical absorption spectra recorded before and after doping concentrations multi...

in this research, we studied the structure, properties and nmr parameters of interaction f2 gas with pristine and 3c-doped (8, 0) zigzag models of boron phosphide nanotubes (bpnts). in order to reach these aims, we considered four different configurations for adsorption of f2gas on the outer and inner surfaces of bpnts. the structures of all models were optimized by using density functional the...

Metal-ion capacitors could merit advantages from both batteries and capacitors, but they need to overcome the severe restrictions their sluggish reaction kinetics of battery type electrode low specific capacitance capacitor for high energy power density. Herein, we use Kirkendall effect first time synthesize unique tubular hierarchical molybdenum dioxide with encapsulated nitrogen-doped carbon ...

introduction: ablative and nonablative lasers have been used to treat melasma. we aimed to assess and compare the combining q-switched nd:yag laser (qsnyl) and fractional erbium:yag laser (feyl) with qsnyl alone in treatment of melasma. methods: this randomized controlled clinical trial was performed in our research center during 2013-2014. women with melasma and without a history of keloid for...

Organic light-emitting diodes (OLEDs) with a Ba-doped tris(8-quinolinolato)aluminum(III) (Alq3) layer were fabricated to reduce the barrier height for electron injection and to improve the electron conductivity. In the OLED consisting of glass/ITO/4,4',4"-tris[2-naphthylphenyl-1-phenylamino]triphenylamine (2-TNATA, 30 nm)/4,4'-bis[N-(1-napthyl)-N-phenyl-amino]-biphenyl (NPB, 18 nm)/Alq3 (42 nm)...

In previous work, we reported the growth of well-structured single-walled carbon nanotubes (SWNT) by CO disproportionation on Co:Mo/SiO2 catalysts. We have proposed that high SWNT selectivity can only be obtained when most of the Co in the sample is interacting with Mo and forming a cobalt–molybdate surface layer. In this contribution, we report further evidence to the hypothesis by an investig...

A variety of 0–20 mol% molybdenum ions (Mo3+)-doped sodium rare-earth (RE) fluoride upconversion nanowires (UCNW) were prepared by Coprecipitate–Solvothermal Ion-Exchange (CSIE) method. In this study, the Mo3+-doped hydroxide [REMo(OH)3] precursors synthesized coprecipitation–solvothermal Following, hexagonal phase (β-NaGdF4: Yb3+/Tm3+/Mo3+, abbreviated as NaREMoF4) successfully ion-exchange re...

Titanium(Ti) and zirconium(Zr) have been widely researched in the field of biomedical materials, due to their excellent mechanical properties and biocompatibility. They belong to group IVa in the periodic table, and are known to have similar chemical properties, and no toxic effects. However, they do not possess antibacterial properties. Inflammation and infection, which are usually caused by a...
