A novel atomic layer deposition process for the preparation of fluoride thin films in a temperature range of 225 degrees C-400 degrees C is introduced. The crystallinity, morphology, composition, thicknesses, refractive indices, and transmittance of the films are analyzed. Low impurity levels are obtained at 350 degrees C-400 degrees C with good stoichiometry. Refractive indices of 1.34-1.42 fo...

The production of 1,3-butadiene from ethanol was carried out using ash as a catalyst in combination with Zr and Mg. catalytic experiments were at 350–400 °C different weight hourly space velocity (WHSV). catalysts that used combined follows: Ash, Ash:MgO (weight ratio 1:1), (1:2), (1:3), Ash: MgO/ZrO2 (1:1:1). characterization the BET, SEM, XRD, TGA, XPS, respectively. yield bare 65% 400 2.5 h−...

BACKGROUND/AIMS The objective of this study was to compare the degree of hepatic enhancement and image quality using contrast media of different iodine concentrations with the same iodine dose. METHODS From July 2011 to June 2013, 50 patients with chronic liver disease who underwent baseline and follow-up 128-slice multidetector computed tomography(MDCT) using contrast media with 350 mg I/mL ...

The conversion of used lubricating oil towards fuel by catalytic is a suitable way to recycle waste oil. Catalyst has key role in conversion. Therefore this research was study the cracking oil, and thus its properties as an alternative for over aluminum fosfate. experiments were carried out batch microreactor at temperature 350-400 oC, atmospheric initial air pressure, 5% w/w catalyst concentra...

Using the hamster cheek pouch carcinogenesis model, we explore which fluorescence excitation wavelengths are useful for the detection of neoplasia. 42 hamsters were treated with DMBA to induce carcinogenesis, and 20 control animals were treated only with mineral oil. Fluorescence excitation emission matrices were measured from the cheek pouches of the hamsters weekly. Results showed increased f...

A conductometric H2, NO2, and hydrocarbon gas sensor based on single-crystalline zinc oxide (ZnO) nanobelts has been developed. The nanobelt sensitive layer was deposited using a radio frequency (RF) magnetron sputterer. The microcharacterization study reveals that the nanobelts have a single crystal hexagonal structure with average thickness and width of about 10 and 50 nm, respectively. The s...

With rising energy demand and depleted traditional fuels, solar cells offer a sustainable clean option. In recent years, due to its acceptable band gap, high absorption coefficient, inexpensive cost, iron pyrite (FeS2) is popular material for cells. Earth abundance nontoxicity further boost photovoltaic possibilities. The current study examined the influence of sulfurization at 350–400 °C on la...
