Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Inhibition Effect of N, N'-Dimethylaminoethanol on the Corrosion of Austenitic Stainless Steel Type 304 [PDF]

, 2012
The effect of N,N'-dimethylaminoethanol on the corrosion of austenitic stainless steel type 304 in 3M H2SO4 has been studied by weight-loss method and linear polarization measurement in different concentrations of the compound.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Electrochemical Studies on the Inhibitive Action of Damssisa and Halfabar on the Alkaline Corrosion of Zinc

International Journal of Electrochemical Science, 2014
The inhibitive effect of Damssisa and Hlfabar extracts on the corrosion of zinc in aqueous solutions of 0.5 M sodium hydroxide were investigated at 30 °C by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques ...

Rank-Dependent Measures of Bi-Polarization and Marginal Tax Reforms [PDF]

In this paper, we investigate a dual class of bi-polarization indices, namely rank-dependent bipolarization indices. We show that these indices may be characterized with the generalized positional transfer sensitivity property.

Tunneling conductance in Superconductor/Ferromagnet junctions: a self consistent approach

, 2008
We evaluate the tunneling conductance of clean Ferromomagnet/Superconductor junctions via a fully self-consistent numerical solution of the microscopic Bogoliubov-DeGennes equations.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Corrosion rate determination of austenic steels in calcium hypochlorite solutions

Zaštita Materijala, 2016
This paper presents the results of testing the corrosion resistance of austenitic chromium-nickel steel X6 CrNiTi 18-10 and X6 CrNiNb 18-10 in solutions of calcium hypochlorite. For the tests were used potentiodynamic measurement methods.

Stability of vector bundles on curves and degenerations

, 2014
We observe that if we are interested primarily in degeneration arguments, there is a weaker notion of (semi)stability for vector bundles on reducible curves, which is sufficient for many applications, and does not depend on a choice of polarization.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.
