The volatile gas isoprene is emitted in teragrams per annum quantities from the terrestrial biosphere and exerts a large effect on atmospheric chemistry. Isoprene is made primarily from recently fixed photosynthate; however, alternate carbon sources play an important role, particularly when photosynthate is limiting. We examined the relative contribution of these alternate carbon sources under ...
The energetic materials have different military and civilian usages and development of new materials with higher efficiency is of interest. Because of hazards related to the synthesis of the energetic materials and to reduce laboratory related expenses, nowadays, using computational methods to evaluate the properties of the energetic compounds such as heat of formation, density, pressure ...
Co-utilization of carbon sources in microbes is an important topic in metabolic engineering research. It is not only a way to reduce microbial production costs but also an attempt for either improving the yields of target products or decreasing the formation of byproducts. However, there are barriers in co-utilization of carbon sources in microbes, such as carbon catabolite repression. To overc...
plackett-burman design was used for selection of important media components such as carbon and nitrogen sources and minerals which affect poly(hydroxybutyrate) production and cell growth of methylobacterium extorquens dsmz 1340. among the studied variables, nitrogen and phosphorus sources, mgso4 and most of the trace elements were found to be significant variables for phb production from methan...
Duplication-containing cells are selected when growth of Salmonella typhimurium is limited by the availability of any one of several carbon and energy sources. Under conditions of extreme starvation, growth occurs almost exclusively in the duplication-containing fraction of the population. Cells with duplications of one large segment of the chromosome are repeatedly selected regardless of which...

The explosion material due to inner pressure have structural instability and this subject special in case of compounds contain nitrate, nitro, di-azo, and azide agents, …,while show in higher temperature than normal media will be greater. thus, the compound is added as a stabilizer to the materials that are capable of reacting with the products of decomposition of the propellant and stable th...
Widespread use of ionizing radiation in medicine, industry, agriculture, education and research, the increasing production of nuclear waste and nuclear incidents, has exposed humans and organisms to this radiation. Despite the benefits of ionizing radiation, these beams can cause serious damage to living systems. Hence, the need for radiation protection actions requires accurate, fast, inexpens...
The preparation of (hetero)arylamines has been significantly advanced by developments in transition metal-catalyzed Csp2–N coupling (e.g., Buchwald–Hartwig, Chan–Lam, and Ullmann couplings). As a complement to these strategies, our group recently demonstrated the reductive arylboronic acids nitro compounds, initially nitro(hetero)arenes more nitromethane, an organophosphorus-catalyzed method op...
