Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

open access: yesAdvanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Ab initio density functional investigation of B_24 cluster: Rings, Tubes, Planes, and Cages [PDF]

open access: yes, 2003
We investigate the equilibrium geometries and the systematics of bonding in various isomers of a 24-atom boron cluster using Born-Oppenheimer molecular dynamics within the framework of density functional theory.

Characterization of Macro/Microstructure and Corrosion Resistance of Austenitic Gas Tungsten Arc Welding Cladding

open access: yesAdvanced Engineering Materials, EarlyView.
Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Transient interactions of boron carbide with molten uranium oxide

open access: yesNuclear Materials and Energy, 2021
Thermodynamic equilibrium calculations have shown that, at the elevated temperatures anticipated during severe accidents, uranium oxide-boron carbide interactions are likely to result in significant boron volatilization and the formation of uranium ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Triarylborane-“Click” Fluorescent Tag for Orthogonal Amino Acid Labelling, Interactions with DNA, Protein, and Cyclodextrins

open access: yesPharmaceuticals, 2023
The innovative design of a triarylborane (TB)-dye with one NMe2-alkylated (propargylated) group and one NMe2 group yielded a system that is both an NMe2 π-donor and an inductive NMe2-alkyl cationic acceptor.

THE REACTION OF TETRAMETHYLSILANE WITH BORON TRIBROMIDE [PDF]

open access: yes, 2001
The reaction of tetramethylsilane with boron tribromide in deuterochloroform in ambient temperature or at 40°C led to bromotrimethylsilane (3) and to dibromomethylborane (4). Identity of products was confirmed by NMR spectroscopy.
