Analytical separations using molecular micelles in open-tubular capillary electrochromatography
(2002)Open-tubular capillary electrochromatography (OT-CEC) is an alternative approach to conventional CEC. The primary advantage of OT-CEC is the elimination of problems associated with frits and silica particles in conventional ...

Chiral Separations Using Polymeric Surfactants and Polyelectrolyte Multilayers in Open-Tubular Capillary Electrochromatography
(2003)In this study, fused-silica capillaries are modified using a polyelectrolyte multilayer (PEM) coating procedure in open-tubular capillary electrochromatography. The PEM coating was constructed in situ with alternating ...

Large positive magnetoresistance in nonstoichiometric NiMnSb thin films on silicon
(2004)The transport properties of pulsed-laser-deposited NiMnSb films on silicon as a function of film thickness were discussed. It was found that a low-temperature upturn was observed in the resistivity for film thicknesses of ...

Mechanical and tribological properties of hard aluminium-carbon multilayer films prepared by the Laser-Arc technique
(1998)The method of laser-induced vacuum arc (Laser-Arc) combines the good controllability of pulsed laser deposition with the high efficiency of a vacuum arc technique. One advantage of this technique is the reduction of droplets, ...

Article
Multilayer composite ceramic-metal-DLC coatings for sliding wear applications
(1996)The design of anti-friction coatings able to perform well in different wear conditions without lubricants requires a combination of adequate hardness and toughness, good adhesion, a low friction coefficient and a low wear ...

Studies of the tribological and mechanical properties of laminated CrC-SiC coatings produced by r.f. and d.c. sputtering
(1997)Multilayer CrC-SiC coatings were produced by both direct current and radio frequency sputtering of Cr and Si targets in an Ar-C2H2 atmosphere. Coatings of constant thickness of about 4 μm, but with the number of layers ...
