Cadmium sulphide (CdS) thin films were deposited onto glass substrates by chemical bath deposition (CBD) from a bath containing cadmium acetate, ammonium acetate, thiourea and ammonium hydroxide. The CdS films were annealed in air at various temperatures (350, 400 and 450 °C) for 60 minutes, and times (5, 15, 30, 45 and 60 minutes) at constant temperature (400 °C) in order to investigate the in...
Novel bichromophoric fluorescent photolabile protecting group, (5-dansyloxy-3-hydroxynaphthalen-2-yl)methyl (DNS-NQMP), allows for the independent photochemical release and fluorescent imaging of caged substrates. Irradiation of DNS-NQMP-caged alcohols and carboxylic acids with 300 or 350 nm light results in fast (k(release) ~ 10(5) s(-1)), efficient (Φ = 0.2), and quantitative release of the s...
The hydrogen production from ammonia decomposition on commercial 5 wt.% Ru/C (C: activated carbon) catalyst with different cesium (Cs) loadings at lower temperatures of 325–400 °C in the fixed-bed reactor was experimentally investigated. Based parameters used this work, results showed that conversion 350 is increased increasing Cs/Ru molar ratio, and it reaches its maximum value ratio 4.5. Afte...
Columnar thin films of undoped ceria were grown by metal-organic chemical vapor deposition. The films, deposited on Pt-coated MgO(100) substrates, display a columnar microstructure with nanometer scale grain size and ~30% overall porosity. Through-plane (thickness mode) electrical conductivity was measured by AC impedance spectroscopy. Proton conduction is observed below 350-400 °C, with a magn...
: In this study, direct-current magnetron sputtering was used to fabricate Ti-doped indium tin oxide (ITO) thin films. The sputtering power during the 350-nm-thick thin-film production process was fixed at 100 W with substrate temperatures increasing from room temperature to 500 °C. The Ti-doped ITO thin films exhibited superior thin-film resistivity (1.5 × 10-⁴ Ω/cm), carrier concentration (4....
Building cost-effective models is of academic and practical value for fast measurement of soil properties, especially at a farm-scale. The aim of this study is to build quantitative models for soil total nitrogen (TN) and total carbon (TC) using visible and near infrared (VIS-NIR) spectroscopy. Dried samples (n=122) collected from an experimental farm, at Silsoe, Bedfordshire, United Kingdom, w...
Carbon ion radiotherapy at HIMAC started in 1994 using two horizontal and two vertical beam ports with broad beam method. The maximum beam energy extracted from accelerators was 400 MeV/n for the horizontal beam port, and 350 MeV/n for the vertical one. In recent years, the scope of diseases that can be treated by the carbon ion radiotherapy has widened and their tumor targets have varied in di...
به منظور بررسی امکان کشت پاییزه عدس در شرایط دیم و مقایسه آن با کشت معمول (بهاره) و نیز تعیین تراکم بذر مناسب در هر یک از فصلهای کاشت، این پژوهش در سال زراعی 88-1387 در شهرستان خرمآباد اجرا گردید. آزمایش دارای دو عامل فصل کاشت (پاییزه و بهاره) و تراکم بذر (در پنج سطح 200، 250، 300، 350 و 400 بذر در مترمربع) بود که به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در چهار تکرار بررسی شد. نتایج ...
