A research has been carried out to simulate an atom transfer radical copolymerization (ATRcP) system of styrene and n-butyl acrylate using the stochastic Monte Carlo method and to investigate the variation of reactant concentration, average molecular weight and molecular weight distribution, average sequence length and sequence length distribution, different dyad fractions and copolymer composition as a function of styrene feed fraction. To this end, a finely tuned program was written in C++ language ...

Excessive application of pesticides to control pests and weeds leads to contaminating bodies of water and health problems for consumers. The present study was designed to investigate the concentration of pesticides in raw water originated from the Marun River as well as the treated water of the drinking water treatment plant in Behbahan City. The efficiency of each treatment process was evaluated. Moreover, the health risks caused by detectable pesticides for consumers of treated water were assessed. ...

Abstract Microorganisms overcome the considerable hurdle of respiring extracellular solid substrates by deploying large multiheme cytochrome complexes that form 20 nanometer conduits to traffic electrons through the periplasm and across the cellular outer membrane. Here we report the first kinetic Monte Carlo simulations and single‐molecule scanning tunneling microscopy (STM) measurements of the Shewanella oneidensis MR‐1 outer membrane decaheme cytochrome MtrF, which can perform the final electron ...

This study evaluated toxic metal concentration in raw milk and related potential health risks. 100 raw milk samples and 30 water samples consumed by cows were gathered from 10 dairy farms in Behbahan county, and Pb and Cd were analyzed by Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). In raw milk samples, mean Pb and Cd levels were 0.55 ± 0.09 and 0.0031 ± 0.0004 mg/l, respectively. Concentrations of Pb and Cd in cows' drinking water were 0.0035 ± 0.0007 and 0.0022 ± 0.0001 mg/l, respectively. ...

Metal-reducing bacteria, such as Shewanella oneidensis MR-1, have evolved extracellular electron transfer (EET) mechanisms to external surfaces, allowing them to use abundant minerals as respiratory electron acceptors, instead of oxygen or other soluble oxidants that would normally diffuse inside cells. By performing EET at electrodes, such microbes can serve as biocatalysts for converting the energy stored in fuels to electricity, or vice versa, in renewable energy technologies. Furthermore, a biophysical ...
