This study was conducted to evaluate the effect of titanium dioxide and titanium oxide foliar application during two growing stage on growth and forage production of maize during 2012 growing season in the research farm of Islamic Azad University of Varamin-Pishva Branch. The experimental design was randomized complete blocks arranged in factorial with four replications. The factors were includ...

A lithium carbonate-based bi-layered electron injection layer was introduced into inverted organic light-emitting diodes (OLEDs) to reduce operation voltages and achieve carrier balance. Ultraviolet photoemission spectroscopy was used to confirm the existence of an interfacial dipole between the organic and lithium carbonate layers, which is a dominating factor related to the device performance...

A semiclassical Monte Carlo technique is employed to simulate the steady-state electron transport in silicon dioxide at intermediate and high electric fields. The electronic structure is modelled by a single parabolic, by a single nonparabolic as well as an isotropic four-band model. We find that the electronic behavior of silicon dioxide is mainly influenced by a single nonparabolic conduction...

This study evaluates the effectiveness of vapour-phase deposition for creating sub-monolayer coverage of aminopropyl triethoxysilane (APTES) on silicon in order to exert control over subsequent gold nanoparticle deposition. Surface coverage was evaluated indirectly by observing the extent to which gold nanoparticles (AuNPs) deposited onto the modified silicon surface. By varying the distance of...

The biocompatibility and biofouling of the microfabrication materials for a MEMS drug delivery device have been evaluated. The in vivo inflammatory and wound healing response of MEMS drug delivery component materials, metallic gold, silicon nitride, silicon dioxide, silicon, and SU-8(TM) photoresist, were evaluated using the cage implant system. Materials, placed into stainless-steel cages, wer...

rapid thermal processing (rtp) has become a key technology for semiconductor device manufacturing in a variety of applications, such as thermal oxidation, annealing, and thin-film growth. hence, understanding the radiative properties of silicon and other relevant materials is essential for the analysis of the thermal transport processes. we have analyzed and calculated the spectral, directional...

Abstract This work aimed to investigate the interaction between salt stress and application of silicon dioxide-nanoparticles. In this study, gerbera plants grown in soilless culture were supplied with nutrient solutions different NaCl concentrations (0, 5, 10, 20 30 mM) combination SiO 2 -NPs spray 25 50 mg · L −1 ). Exposure salinity increased sodium concentration but decreased potassium calci...

Recent evidence suggests silicon dioxide micro- and nanoparticles induce cytotoxic effects on lung cells. Thus, there is an increasing concern regarding their potential health hazard. Nevertheless, the putative toxicity of nanoparticles in mammalian cells has not yet been systematically investigated. We previously noted that several metallic oxide nanoparticles exert differential cytotoxic effe...

We use single nanoparticle luminescence microscopy to determine a distribution of individual chromophores present in porous Si nanoparticles. From these distributions, we determine the average number of emitting chromophores in each nanoparticle and the fluorescence emission count rate of a single chromophore within the porous silicon nanoparticle. We also show that the same size nanoparticles ...
