elastomer compound based on nr/br was prepared using different kinds of nano-zno and zno. the effect of zinc oxide as an activator of sulfur cure on the mechanical and morphological properties of the compound was studied. the result of the mechanical properties showed that the tensile strength, elongation-at-break, resilience, and abrasion resistance of the compound prepared by zno (4 phr) are ...
In the emerging issue of increased multi-resistant properties in food borne pathogens, zinc oxide (ZnO) and nano-particle zinc oxide (nano-ZnO) are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of nano-ZnO towards pathogens microbes Bacillus subtilus NRRL B-543, Bacillus megaterium ATCC 25848, Staph...
In this report, we describe the synthesis and characterization of 1,3-bis(hexyloxy)propan-2-yl nitrate (NDHP), a novel organic mono nitrate. Using purified xanthine oxidoreductase (XOR), chemiluminescence and electron paramagnetic resonance (EPR) spectroscopy, we found that XOR catalyzes nitric oxide (NO) generation from NDHP under anaerobic conditions, and that thiols are not involved or requi...
The objective of this study was to quantify the influence of zinc oxide nanoparticles (nanoZnO) on the water repellency and dimensional stability of beech wood. Beech wood blocks were treated with a nano-ZnO solution at four treatment levels (0, 10,000, 20,000, and 40,000 ppm) using a modified dip method. Also, a thermal treatment was performed at 60 and 120°C. After conditioning the samples, w...
Metallic molybdenum (Mo(o)) wires with diameters ranging from 15 nanometers to 1.0 micrometers and lengths of up to 500 micrometers (0.5 millimeters) were prepared in a two-step procedure. Molybdenum oxide wires were electrodeposited selectively at step edges and then reduced in hydrogen gas at 500 degrees C to yield Mo(o). The hemicylindrical wires prepared by this technique were self-uniform,...
Alkalinity of the soil is one of the main problems in some soils of Iran, which reduces the solubility and reduces the absorption of essential nutrients, including the iron element for the plant. Iron deficiency in plants reduces photosynthesis and reduces production. The present experiment, as a factorial, was conducted in the form of a statistical design of complete randomized blocks and in 3...
A novel multilayer material system consisting of lanthanum and molybdenum nano-layers for both broadband and highly reflecting multilayer mirrors in the energy range between 80 and 130 eV is presented. The simulation and design of these multilayers were based on an improved set of optical constants, which were recorded by extreme ultraviolet (XUV)/soft-x-ray absorption measurements on freestand...
