because most contaminants in water create strong interactions with hydrophobic surfaces, there are usually problems such as flux decline and pore blocking in polyethylene (pe) membranes due to irreversible adsorption of foulants on their intrinsic hydrophobic surface. therefore, in this work, attempts were made to improve the properties of pe membranes in terms of water flux and membrane foulin...
The cell surfaces of a range of variants of Streptococcus salivarius HB, altered in cell wall antigen composition, were compared with those of the parent with respect to adherence, ability to adsorb to hexadecane, morphology, and exposure of lipoteichoic acid (LTA). Adherence to host surfaces was measured by using both saliva-coated hydroxyapatite beads and tissue-cultured HeLa cells, and inter...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
The background shows a water layer on the graphene containing Stone–Wales and double vacancy defects. The structural and electronic properties of the systems have been studied by density functional tight-binding method, to understand graphene's stable electronic characteristics. Defects are inevitably present in graphene and can alter its properties and thus its applications. Interestingly, we ...
High uniformity of hydrophobic F4-TCNQ doping in the spiro-OMeTAD layer hinders dopant migration towards anode as well aggregation, leading to a T 80 shelf-lifetime >1 year.
