فعالیت کاتالیستی و انتخاب پذیری هیدروژن در کاتالیست های مس بنیان که توسط اکسیدهای فلزی ZnO، 2CeO و 3O2Al بهبود یافته اند، برای تولید گزینشی هیدروژن در فرایند ریفورمینگ متانول با بخارآبمورد ارزیابی قرار گرفته است. نانوکاتالیست های 2CuO-ZnO-CeO و 3O2-Al 2CuO-ZnO-CeO به روش احتراقی (اوره به عنوان سوخت سنتز احتراقی)...
Overdoped Tl 2Ba 2CuO 61d exhibits persistent photoconductivity at low temperatures. This effect has been observed before only in underdoped RBa 2Cu 3O 72d (R5rare earth or yttrium!. Contrary to RBa 2Cu 3O 72d , Tl 2Ba 2CuO 61d shows either a persistent increase or decrease of the carrier density with illumination, depending on doping and wavelength of the incident light. Thus it is possible to...
Microsomal glutathione transferase 1 (MGST1) is an antioxidant enzyme located predominantly in the mitochondrial outer membrane and endoplasmic reticulum and has been shown to protect cells from lipid peroxidation induced by a variety of cytostatic drugs and pro-oxidant stimuli. We hypothesized that MGST1 may also protect against nanomaterial-induced cytotoxicity through a specific effect on li...
Based on previously published hydroponic plant, planktonic bacterial, and soil microbial community research, manufactured nanomaterial (MNM) environmental buildup could profoundly alter soil-based food crop quality and yield. However, thus far, no single study has at once examined the full implications, as no studies have involved growing plants to full maturity in MNM-contaminated field soil. ...
Semiconducting-ionic conductors have been recently described as excellent electrolyte membranes for low-temperature operation solid oxide fuel cells (LT-SOFCs). In the present work, two new functional materials based on zinc oxide (ZnO)-a legacy material in semiconductors but exceptionally novel to solid state ionics-are developed as membranes in SOFCs for the first time. The proposed ZnO and Z...
Abstract Ethanol steam reforming was studied over Ni supported catalysts. The effects of support (Al 2 O 3 , Al –ZnO, and –CeO ), metal loading, catalyst activation method, steam-to-ethanol molar feed ratio were investigated. properties catalysts by N physisorption, TPD-CO X-ray diffraction, temperature programmed reduction. After activity tests, the analyzed TOC analysis. catalytic measurement...
Predictions of environmental concentrations of engineered nanomaterials (ENM) are needed for their environmental risk assessment. Because analytical data on ENM-concentrations in the environment are not yet available, exposure modeling represents the only source of information on ENM exposure in the environment. This work provides material flow data and environmental concentrations of nine ENM ...
in this experiment two hundreds one day old broiler chicks (ross 308) in 5 treatments and 4 replicates were used based a completely randomized design. experimental treatments were: control treatment (basal diet), clove essential oil (ceo) at different levels (100, 300 and 500 mg/kg + basal diet) and 600 mg/kg flavophospholipol antibiotics (fpa) + basal diet. results showed that feed intake was ...
