Pure and mixed ZnO-SiO2 particles were prepared by flame spray pyrolysis (FSP) of zinc acetate (ZA) and either hexamethyldisiloxane (HMDSO) or SiO2-sol dispersed in either methanol or a water-in-oil emulsion. The product particles were characterized by nitrogen adsorption, infrared absorption and X-ray diffraction. The evolution of solid or hollow particle formation along the flame axis was elu...

A 12-year-old male child presented with bilateral visual loss and short stature. He had dysmorphic faces, barrel shaped chest and short limbs with enlarged peripheral joints. In addition he had bilateral retinal detachment with secondary cataract formation. Skeletal survey revealed irregular platyspondyly, hypoplastic femoral head and enlarged epiphysis of long bones with cloud like calcificati...

A silicon oil-filled glass capillary array is proposed as an anisotropic diffusion MRI phantom. Together with a computational/theoretical pipeline these provide a gold standard for calibrating and validating high-q diffusion MRI experiments. The phantom was used to test high angular resolution diffusion imaging (HARDI) and double pulsed-field gradient (d-PFG) MRI acquisition schemes. MRI-based ...

Its empirical formula is C24H28N2O5•HCl, and its molecular weight is 460.96. Benazeprilat, the active metabolite of benazepril, is a non-sulfhydryl angiotensin-converting enzyme inhibitor. Benazepril is converted to benazeprilat by hepatic cleavage of the ester group. Lotensin is supplied as tablets containing 5 mg, 10 mg, 20 mg, and 40 mg of benazepril hydrochloride for oral administration. Th...

Photovoltaic phenomenon was first observed by E. Becquerel (Becquerel) in 1839. He observed the electric current-lit silver electrode, immersed in the electrolyte. In 1894, taking advantage of the observed photoconductivity phenomenon in amorphous selenium the semiconductor solar cell was developed. The very first silicon p-n junction solar cell was made in 1954, energy conversion efficiency of...

considering the positive effects of silicon on salinity resistance by some agricultural plants, an investigation was conducted with a completely randomized design of three replications. the main objective was to determine the effect of silicon on nutrient content and nitrate accumulation in lettuce. electrical conductivity was adjusted at 3 mmhos/cm through addition of nacl. silicon was added t...

introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...

silicon has useful effects on growth and yield of many plants. the aim of the present study is to investigate the impact of nano silicon oxide on proliferation and improvement of some growth traits of apple, cultivar gala. thus, an experiment was designed based on completely randomized design (crd) with five levels of nano silicon oxide concentrations (0, 25, 50, 100 & 200 ppm) in five replicat...

Silicon nanopillars are important building elements for innovative nanoscale systems with unique optical, wetting, and chemical separation functionalities. However, technologies for creating expansive pillars arrays on the submicron scale are often complex and with practical time, cost, and method limitations. Herein we demonstrate the rapid fabrication of nanopillar arrays using the thermal de...
