Electrochemical study on microbiology-related corrosion of metallic dental materials.
Microbiology-related corrosion has been noted in industry for many years. It is widely recognized that microorganisms affect the corrosion of metal and alloys immersed in aqueous environments. Under similar conditions, the effect of bacteria in the oral environment on the corrosion of dental metallic materials remains…
Scaling laws for the resistivity increase of sub-100 nm interconnects
A physically based model is used to describe the resistivity increase of sub-100 nm copper interconnect structures. The main factors determining the increase are additional scattering of electrons at the surface as well as at the grain boundaries of the conductor. The model has been applied to several sets of experime…
Date palm fibre reinforced composite as a new insulating material
Several panels of date palm leave (DPL) reinforced composites were fabricated using either autoclaving technique with vacuum bagging or press moulds with controlled temperature. Several fibre orientation and dimensions were tested. Two types of resins were selected. The first was a high temperature curing Phenolic (ph…
Storage and Release of Soluble Hexavalent Chromium from Chromate Conversion Coatings on Al Alloys: Kinetics of Release
The release of chromate ions from chromate conversion coatings (CCCs) on Al alloys was studied, and the effect of aging of CCCs on the chromate release kinetics was investigated. Chromate release from CCCs into aqueous solutions was monitored by measuring the change in the chromate concentration in solution using UV-v…
Scale-Resolved Electrochemical Surface Structuring of Titanium for Biological Applications
Scale-resolved electrochemical surface structuring of titanium leads to well-defined topographies at the micrometer and nanometer scales, which are of interest for biomedical applications. Electrochemical procedures are described that lead to improved reproducibility and more precise shape control in through-mask elec…
Modeling of 3D Angle Interlock Woven Fabric Composites
A three dimensional micromechanical modeling approach was previously developed for predicting elastic constants of 2D woven fabric composites [Sheng, S.Z. and Hoa, S.V. (2001). Three dimensional micromechanical modeling of woven fabric composites. Journal of Composite Materials, 35(19): 1701-1729.]. In this paper, the…
Highly effective ferric hydroxide supported gold catalyst for selective oxidation of CO in the presence of H2This work was financially supported by The National Natural Science Foundation of China (No. 20173068).
Ferric hydroxide supported Au prepared with co-precipitation without heat treatment could be a very effective catalyst for selective CO oxidation in the presence of H2 at lower temperatures.
Plasticizer Effect on Grease Barrier and Color Properties of Whey‐protein Coatings on Paperboard
ABSTRACT Whey protein concentrates with ˜80% protein (WPC‐80) plasticized with 0.64 M glycerol or sucrose, or with 0.34 or 0.64 M sorbitol or polyethylene glycol (PEG) 200, produced flexible films. WPC‐80 with hydrolyzed lactose required addition of less sucrose to produce flexible films. WPC‐80 films formed as coatin…
A novel approach to preparing nano-size Co3O4-coated Ni powder by the Pechini method for MCFC cathodes
The dissolution of nickel oxide cathodes in the electrolyte is one of the major technical obstacles to the commercialization of molten carbonate fuel cells (MCFC). A novel alternative cathode material for MCFC was synthesized, which was made of nano-size Co3O4 coated on the surface of Ni powder using a polymeric precu…
A CuII Chain Compound Showing a Ferromagnetic Coupling through Triple N1,N2‐1,2,4‐Triazole Bridges
Abstract [Cu(hyetrz) 3 ](CF 3 SO 3 ) 2 ·H 2 O [hyetrz = 4‐(2′‐hydroxyethyl)‐1,2,4‐triazole] represents the first structurally characterised ferromagnetically coupled Cu II chain compound containing triple N 1 , N 2 ‐1,2,4‐triazole bridges. catena ‐ [μ‐Tris{4‐(2′‐hydroxyethyl)‐1,2,4‐triazole‐ N 1 , N 2 }copper( II )] b…
Macro-cellular silica foams: synthesis during the natural creaming process of an oil-in-water emulsion
The room-temperature synthesis of a macro-mesoporous silica material during the natural creaming process of an oil-in-water emulsion is reported. The material has 3-dimensional interconnected macropores with a strut-like structure similar to meso-cellular silica foams with mesoporous walls of worm-hole structure. The…
Intercalation of poly(propyleneoxide) amines (Jeffamines) in synthetic layered silicas derived from ilerite, magadiite, and kenyaite
The synthetic layered silicates Na+-ilerite (Na2Si8O17·nH2O), Na+-magadiite (Na2Si14O29·nH2O), and K+-kenyaite (K2Si20O41·nH2O) were converted to the corresponding layered silicic acids (silicas) through the stoichiometric replacement of the gallery alkali metal ions with protons. The protonated derivatives were subse…

Static electromigration analysis for on-chip signal interconnects
With the increase in current densities, electromigration has become a critical concern in high-performance designs. Typically, electromigration has involved the process of time-domain simulation of drivers and interconnect to obtain average, root mean square (r.m.s.), and peak current values for each wire segment. How…
Theory and simulation of biaxial nematic and orthogonal smectic phases formed by mixtures of board-like molecules
Variational cluster calculations and Monte Carlo simulations are applied to hard-body board-like models of biaxial molecules forming liquid crystalline phases. The molecular long axes are assumed for simplicity to be fully oriented. Depending on the extent of transverse anisometry in the molecular shape, these systems…
