Chemical agglomeration can reduce the particulates (including PM2.5) concentration emitted from fly ash particulates and the wet flue gas desulfurization (WFGD) system. However, the calcium-based slurries affect the regulation of agglomeration compared to water, in particular, the wettability of the particulates and the viscosity of the calciumbased slurry. The wettability and the viscosity are...

In recent years, metal nano particles such as silver, copper and zinc have developed in textilefinishing. Copper nano particles are used in wound dressings and socks to give them antibacterialproperties. In the present paper, cotton fabrics were treated with different concentrations of Cu nanoparticles colloidal solution. For investigation of the durability of nano particles on cotton fabric,la...

When a nonequilibrium growing interface in the presence of a wall is considered a nonequilibrium wetting transition may take place. This transition can be studied trough Langevin equations or discrete growth models. In the first case, the Kardar-Parisi-Zhang equation, which defines a very robust universality class for nonequilibrium moving interfaces, with a soft-wall potential is considered. W...

The aim of this study was to evaluate the influence of disintegration mechanism of various types of disintegrants on the absorption ratio (AR), wetting time (WT), and disintegration time (DT) of orodispersible tablets (ODTs). ODTs were prepared by direct compression using mannitol as filler and disintegrants selected from a range of swellable, osmotic, and porous disintegrants. Tablets formed w...

We have investigated the quantum dot (QD) carrier capture mechanism using continuous wave photoluminescence as a function of the optical excitation intensity using a sample with a QD density gradient across its surface ranging from 0 to 1.8 £ 10 cm. Modelling of the carrier kinetics has been described by a set of three coupled rate equations associated with the carrier population in the GaAs ba...

Controlling the microscopic wetting state of a liquid in contact with a structured surface is the basis for the design of liquid repellent as well as anti-fogging coatings by preventing or enabling a given liquid to infiltrate the surface structures. Similarly, a liquid can be confined to designated surface areas by locally controlling the wetting state, with applications ranging from liquid tr...
