Diffusion towards a fractal adsorber is a well-researched problem with many applications. While the steady-state flux towards such adsorbers is known to be characterized by the fractal dimension (D{F}) of the surface, the more general problem of time-dependent adsorption kinetics of fractal surfaces remains poorly understood. In this Letter, we show that the time-dependent flux to fractal adsor...

INTRODUCTION Francisella tularensis, a facultative intracellular Gram-negative bacterium, has rarely been reported as an agent of pericarditis, generally described as a complication of tularemia sepsis. F. tularensis is a fastidious organism that grows poorly on standard culture media and diagnosis is usually based on serological tests. However, cross-reactions may occur. Western blotting allow...

A new material TH-Ge 0.5 Si C 2 -zz has been discovered, which a direct bandgap and broad application prospect in photoelectric devices. The effect of H/F atom adsorption on the structural parameters electrical properties was studied this paper. In nutshell,bandgap can be notable increased by H adsorption, work function electron affinity energy are decreased. While cannot opened full F atom.

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

Zeolites with the faujasite structure (FAU) are extensively used as catalysts and in gas separation. A detailed knowledge of their structure, particularly the positions of extra−framework cations in the case of gas adsorption, is therefore central to understanding their performance. Typically zeolites X (Si/Al ~.1.1−1.5) and Y (Si/Al ~5−11) are used. A common assertion of structural determinati...

A systematic study on the influence of functionality on adsorption of benzoate and phthalate at -alumina–water interface was investigated. Kinetics of adsorption of benzoate and phthalate on -alumina surfaces were performed at constant ionic strength, I= 5× 10−4 mol dm−3 and pH 5 at 25, 30 and 40 ◦C. Kinetics results show that the rate of adsorption of phthalate is ≈2 times more than that of be...

Gas insulated switchgear (GIS) plays an important role in the transmission and distribution of electric energy. Detecting and analyzing the decomposed components of SF₆ is one of the important methods to realize the on-line monitoring of GIS equipment. In this paper, considering the performance limits of intrinsic TiO₂ nanotube gas sensor, the adsorption process of H₂S, SO₂, SOF₂ and SO₂F₂ on f...

The sorption efficiencies of graphene oxide (GO) and functionalized multi-walled carbon nanotubes (f-MWCNTs) were investigated and elucidated to study their potential in treating acid mine drainage (AMD) containing Cu2+, Mn2+, Zn2+, Pb2+, Fe3+ and Cd2+ metal ions. Several layered GO nanosheets and f-MWCNTs were formed via the modified Hummers’ method and the acid treatment of the MWCNTs, respec...

Introduction Adsorption of proteins at a solid-liquid interface is an important phenomenon in biology and highly relevant for the design of biocompatible materials. It is well-known that protein adsorption is one of the first events which take place when a foreign material comes into contact with a living body and is believed to be a key factor in controlling subsequent cellular adhesion. In th...
