Vacancy or not: An insight on the intrinsic vacancies in rocksalt-structured GeSbTe alloys from ab initio calculations
(EPL-EUROPHYS LETT, 2011-07)Rocksalt-structured GeSbTe (GST) phase-change materials contain significant amounts of intrinsic vacancies at one sublattice. On the basis of ab initio total energy calculations, we have shown that the so-called intrinsic ... -
Versatile fabrication of arbitrarily shaped multi-membrane hydrogels suitable for biomedical applications
(Royal Society of Chemistry, 2013-01-28)In this work, arbitrarily shaped multi-membrane hydrogels were successfully fabricated from gel-core templates using the layer-by-layer (LbL) method. Namely, the first gel membrane layer was formed around a gel-core template ... -
Vibrationally resolved molecular-frame angular distribution of O 1s photoelectrons from CO2 molecules
(2005)Vibrationally resolved O 1s photoelectron angular distributions from CO2 molecules, aligned parallel and perpendicular to the electric vector of the incident light, have been measured in the 5 sigma(g)(*) shape resonance ... -
Viscoelastic properties and bioactivity of sol-gel derived gelatin-silicate composites: Effects of the incorporated Ca2+ ions
(2001-05)Several gelatin-silicate composites, with or without incorporation of Ca2+ ions, were synthesized through set-gel processing starting from gelatin and 3- (glycidoxypropyl) trimethoxysilane. The structure around the Si atoms ... -
Visible-light-driven photogenerated cathodic protection of stainless steel by liquid-phase-deposited TiO2 films
(PERGAMON-ELSEVIER SCIENCE LTD, 2012-04-30)The liquid-phase-deposition (LPD) method was developed to prepare N-F-codoped TiO2 films that served as photoanodes for the cathodic protection of SUS304 stainless steel (304SS). The as-prepared LPD-TiO2 films were ... -
Waist cross-linked micelles synthesized via self-assembly guiding radical polymerization
(2009)Amphiphilic micelles with waist cross-linked structure exhibit both core-shell reversing behavior and thermal sensitivity. -
What makes spider silk fibers so strong? From molecular-crystallite network to hierarchical network structures
(ROYAL SOC CHEMISTRY, 2014)A Hierarchical Network (HN) model of soft matter was put forward to explain the mechanical properties of animal silk fibers. At the nano-micro level, the silk fibers consist of a bundle of twisted nano-fibrils with strong ... -
White spot syndrome virus VP24 interacts with VP28 and is involved in virus infection
(J GEN VIROL, 2006-07)White spot syndrome virus (WSSV) is one of the most virulent pathogens causing high mortality in shrimp. Herein, the characterization of VP24, a major structural protein of WSSV, is described. When purified virions were ... -
Wireless passive polymer-derived SiCN ceramic sensor with integrated resonator/antenna

Working Pressure Induced Microstructure and Stress Evolution of Sputtered ZrN Coatings
(2012-02)The influence of working pressure on microstructure and residual stress evolution of magnetron sputtered ZrN coatings were systemically investigated. XPS and XRD results reveal that all as-deposited coatings at varying ... -
X-ray diffraction and X-ray photoelectron spectra of Fe-Cr-N films deposited by DC reactive sputtering
(1999)The effects of nitrogen flow ratio, target area ratio of Cr, and substrate temperature on the structure of DC reactive sputtered Fe-Cr-N ternary films have been studied. X-ray diffraction measurements show that Fe-Cr-N ... -
