In this research, Quantum-mechanical calculations were performed at the HF method with the 6-31+G*basis set and at the B3LYP method with the 6-31+G* basis set in the gas phase and five solvents such as water, DMSO, methanol, ethanol and dichloromethane at six temperatures. According to these theoretical results of IR, we extracted thermo chemical parameters such as enthalpy (∆H Kcal/mol), Gibbs...

We present the case of a 40-year-old woman exposed for 4 h and 30 min to chlorine gas generated by mixing detergents containing hydrochloric acid hypochlorous commit suicide in bathroom. Acute respiratory failure, chemical burns all over face corneal erosion occurred. Despite skin have not been reported after exposure gas, this report suggests that may occur due prolonged even at relatively low...

Agriculture has a key role in greenhouse gas emissions.  As such, the present study aimed to evaluate the greenhouse gas emissions from wheat production in irrigated and rain-fed systems. The primary data were collected from 116 wheat farmers. The results showed that the total greenhouse gas emissions from wheat production in irrigated and rain-fed systems were 637.8 and 65.12 kgCO2eq, respecti...

Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...

carbon nanotubes (cnts), nowadays, are one of the important nanomaterials that can be produce with different methods such as chemical vapor deposition (cvd). growing of cnts via cvd method can be influenced by several operating parameters that can affect their quality and quantity. in this article, the effects of inlet gas mixture temperature on cnt’s local growth rate, total production, and le...

The trend towards decentralization of electricity production, the rising share of stochastic generators and more stringent consumer needs govern the planning of future networks. A widely discussed concept is that of integrated planning of chemical and electrical power systems. The “vision of future energy networks” project goes one step further and proposes a common infrastructure for both gas ...
