Kinetics of Gas−Liquid Reaction between NO and Co(en)33+

Xiang‐li Long、Wen‐De Xiao、Weikang Yuan2005-05-13Industrial & Engineering Chemistry Research

NO can be removed from exhaust gas streams by using a basic solution of cobalt ethylenediamine (en = H 2 NCH 2 CH 2 NH 2 ). The cobalt ethylenediamine acts as a homogeneous catalyst to oxidize NO into soluble nitric dioxide and realize the oxidation and absorption of nitric oxide simultaneously. The dissolved oxygen i…

Remarkable features in lattice-parameter ratios of crystals. II. Monoclinic and triclinic crystals

R. De Gelder、A. Janner2005-05-13Acta Crystallographica Section B Structural Science

The frequency distributions of monoclinic crystals as a function of the lattice-parameter ratios resemble the corresponding ones of orthorhombic crystals: an exponential component, with more or less pronounced sharp peaks, with in general the most important peak at the ratio value 1. In addition, the distribution as a…

Feasibility evaluation of chitosan coatings on polyethylene tubing for biliary stent applications

Chih‐Hsiu Lin、Jui‐Che Lin、Chiung‐Yu Chen 等 6 位作者2005-05-13Journal of Applied Polymer Science

Abstract Endoscopic palliation for the obstructive jaundice caused by biliary or pancreatic malignant tumors is a commonly used medical treatment. However, plastic biliary stents are occluded by sludge deposition caused by bacterial adhesion in 3–5 months. Chitosan, which has both good biocompatibility and antimicrobi…

Adsorption and Interaction of Fibronectin and Human Serum Albumin at the Liquid−Liquid Interface

Sachin Vaidya、Robert Y. Ofoli2005-05-13Langmuir

The goal of this work was to investigate the dynamics of human plasma fibronectin (HFN) at the oil-water interface and to characterize its interactions with human serum albumin (HSA) by total internal reflection fluorescence microscopy (TIRFM). Among key results, we observed that fibronectin adsorption at the oil-wate…

Abstract The growth of silicon macropores under high current densities and high HF concentrations is studied. A new growth mode for porous Si has been found where pores resemble the so‐called current line oriented pores previously discovered in InP. For the achievement of that the electrolyte had to be optimized in re…

Time-domain study of microtrack structure and artifacts

Alexander M. Taratorin、K.B. Klaassen2005-05-13Journal of Applied Physics

To study the microtrack signal, noise and track “skirts” a time-domain technique [A. Taratorin, M. Xiao, and K. Klaassen, IEEE Trans. Mag. 40, 129 (2004)] was used. It shows that the standard microtrack preparation (two-sided dc erasure) suffers from demagnetization caused by the write head fringe fields. Low density…
