The present work aims to ascertain the mechanisms of surfactant (dodecylbenzene sulfonate; DBS) effects on the aggregation behaviors of TiO2 nanoparticles (TiO2-NPs) in natural water samples. Aggregation experiments were conducted at a TiO2-NPs concentration of 10mg/L in deionized water and in natural water samples via dynamic light scattering and Zeta potential determination. Average attachmen...

Application of toxic antibacterial agents is considered necessary to control prevalent fresh water microorganisms in evaporative cooling water systems, but these agents can adversely affect the environment and human health. Alternatively, natural antibacterial water chemistry has been applied in industrial cooling water systems for over 10 years with excellent results. The tower water chemistry...

evaluation of carbon sequestration ability by chlorella vulgaris in water with different salinity expanded abstractintroductionnowadays, cultivation of microalgae in order to reduce co2 has gained attention all around the world. one of the outstanding features is that photosynthetic efficiency of microalgae is greater than that of terrestrial plants. carbon dioxide (co2) has been known as one o...

Natural gas is often associated with nitrogen and heavy compounds. The Heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. Therefore, heavy components separation can be a necessity and produce useful products. Virtually, all natural gases are containing nitrogen ​​that would lower the heating value of natural ...

in order to investigate the effect of water deficit irrigation and natural products on vegetative characteristics of three varieties of chickpea, a field experiment was performed as split-split plot experiment in a randomized complete block design with three replications during 2011 growing season in shahrood (miami). the main plot was drought stress in four levels including normal irrigation (...
