Plasma-boundaries floating in an ionized gas are usually negatively charged. They accumulate electrons more efficiently than ions which leads to the formation of a quasi-stationary electron film at the boundaries. We propose a physisorption-inspired quantum-kinetic description of the build-up of surface charges at inert plasma boundaries, where other surface modifications, in particular, implan...

Engineering flow systems operating under low pressures and/or at the micro/nano scale generally include a physically adsorbed gas layer next to surface. In this paper, we develop scattering kernel that accounts for effect of adsorption, arising from van der Waals interactions, on dynamics molecules impinging solid smooth surfaces. limit bulk density, surface adsorption becomes negligible and re...

Using Molecular Mechanics and Molecular Dynamics methods, we investigated at the atomistic level the topography effects both on physisorption on different crystalline planes of TiO2 anatase and on the competitive adsorption when three different crystallographic faces were simultaneously present in an idealized nanosized crystal interacting with a simple heteroaromatic molecule experimentally us...

Arsenic exposure results in several human cancers, including those of the skin, lung, and bladder. As skin cancers are the most common form, epidermal keratinocytes (KC) are the main target of arsenic exposure. The mechanisms by which arsenic induces carcinogenesis remains unclear, but aberrant cell proliferation and dysregulated energy homeostasis play a significant role. Protein glycosylation...

Carbon nanotube sponges show effective filtration for nanoparticles and dye molecules with different sizes and concentrations from water. The three-dimensional interconnected porous structure formed by entangled nanotubes can trap nanoparticles and molecules by physisorption without the need for chemical functionalization. The sponge filters are potential environmental materials for water treat...
