analyses and thermal infrared channels 4 and 5 noaa- avhrr images. this research was carried out in lut desert located in center of sub-tropical divergence dominant in' iranian plateau. the physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...
The temperature sensitivity of soil organic matter (SOM) decomposition has been a crucial topic in global change research, yet remains highly uncertain. One of the contributing factors to this uncertainty is the lack of understanding about the role of rhizosphere priming effect (RPE) in shaping the temperature sensitivity. Using a novel continuous C-labeling method, we investigated the temperat...
Cylotrimethylenetrinitramine (RDX), with the chemical formula C3H6N6O6, is an energetic organic molecule used widely in commodities of explosives. Its partial stimulation results in decomposition reaction at very high rate. Molecular dynamic technique and LAMMPS code with ReaxFF-lg were employed to simulate initiation of RDX. Potential energy variations of the system were calculated for five di...
Ammonium dinitramide (ADN) with a positive oxygen balance (25.8%) is a metal free- energetic compound, which is used in military explosives and smokeless or green solid propellants. Combustion products of solid propellants based on ADN are clean and smokeless and they do not release hydrogen chloride gas, which can be an excellent alternative compound as an oxidizer in the solid propellant form...
in this paper, we used tetranuclear copper (ii) schiff base complexes, [cu4 (μ-sal2hn) (μ-n3)2(n3)2] (1) and [cu4 (μ-salophen) (μ1, 1-n3)2(n3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of cuo nanoparticles. the crystallinity, purity and morphology of the cuo nanoparticles were characterized by fourier transform infrared (ft-ir), x-ray diffraction (xrd) and s...
