High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Normalized melt curves showing methylation status of promoters P1 and P3 in UKF-NB-4 and IMR-32 before and after using AZA and in combination with VPA.

, 2016
Western blot is showing the effect of 1mM VPA and AZA on CD133 expression in methylated cell lines. (A) Treatment with AZA decreased the methylation of both promoters P1 and P3 in UKF-NB-4 and IMR-32.

Nb-based MXenes for efficient electrochemical sensing of small biomolecules in the anodic potential

, 2020
In this work, we study the electrochemical performance of Nb2CTx and Nb4C3Tx MXenes in the aqueous media and their application as a sensing platform for small biomolecules. Both Nb2CTx and Nb4C3Tx are electrochemically stable up to an anodic potential of

Phenolic acid phenethylesters and their corresponding ketones: Inhibition of 5‐lipoxygenase and stability in human blood and HepaRG cells

Pharmacology Research & Perspectives, 2019
5‐lipoxygenase (5‐LO) catalyzes the biosynthesis of leukotrienes, potent lipid mediators involved in inflammatory diseases, and both 5‐LO and the leukotrienes are validated therapeutic targets.

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.

Effects of Nb addition on glass-forming ability and magnetization behaviors of nanocomposite Nd-Fe-B-Nb strip flakes

, 2014
The influences of Niobium doping on the glass-forming ability (GFA) and magnetization properties of Nd-Fe-B-Nb alloys were investigated. It is found that the GFA of Nd-Fe-B-Nb alloys are improved by the Nb addition.

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.

a critical review of the phenomenon of bond-stretch and distortional isomerism in oxo and sulphido complexes of transition metals [PDF]

, 1993
This thesis describes studies directed towards the preparation of oxo compounds of the early transition metals with a view to assessing their potentials for exhibiting distortional and bond-stretch isomerism.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

Advanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...
