Wetting of solids by aqueous surfactant is important for many commercialapplications such as coatings, detergency, and printing. The surface tension of solution is usually considered as a main factor in wetting, whereas ...

Carboxymethyl chitin (CM-chitin), chitosan, and the blend films of both polymers with polyvinylalcohol (PVA) and polyvinylpyrrolidone (PVP) were prepared by solution casting technique. Glutaraldehyde was used as a crosslinking ...

One of the major air pollutants is volatile organic compounds (VOCs). A number of techniques for removing air pollutants are available such as adsorption, biofiltration and incineration. However, these techniques require ...

Very fine polyvinylalcohol/silatrane composite fibres were successfully prepared using an electrospinning process. These fine composite fibres were converted to silica fibres, with the aim of producing silica fibres having ...

The valuable chemical synthesis of shape selective zeolites is an industrial importance. Para-xylene has been synthesized over pore size regulated zeolites by toluene disproportionation reaction. Effects of catalytic ...

Chitosan with a degree of deacetylation of 94.41% and molecular weight of 4.25 X 105 was wet-spun through a 50-hole (0.1-mm diameter) spinneret using a solution of 7% (w/v) chitosan in 4% (v/v) aqueous acetic acid. A sodium ...

Recently, the normal paraffins market has been growing steadily every year as C10-C14 normal paraffins are used as a feedstock for the production of surfactants such as linear alkyl benzene (LAB). One way to obtain this ...

Transient deformation and breakup of viscoelastic polystyrene (PS) droplets dispersed in an viscoelastic high density polethylene (HDPE) matrix were observed under a simple steady state shearing flow between two transparent ...

In order to reduce the production cost of the modified silica, mixed surfactants of cationic and nonionic surfactants, cetyltrimethyl ammonium bromide (CTAB) and Triton X-100, were employed in the admicellar polymerization ...

The most attractive industrial technique for the separation of p-xylene is selective adsorption with zeolites. An understanding of parameters that influence the effectiveness of the separation is needed in order to achieve ...
