Low-energy Se ion implantation in MoS 2 monolayers

npj 2D Materials and Applications, 2022
In this work, we study ultra-low energy implantation into MoS2 monolayers to evaluate the potential of the technique in two-dimensional materials technology. We use 80Se+ ions at the energy of 20 eV and with fluences up to 5.0·1014 cm−2. Raman spectra of

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

A duo of redox-sensitive pore-loop cysteines controls the activity of the neural ion channel TRPM3

Communications Chemistry
Transient Receptor Potential Melastatin 3 (TRPM3) is a non-selective, Ca2+-permeable ion channel that plays a pivotal role in peripheral thermosensation and nociception.

Triple Junctions as Dislocation‐Like Defects: The Role of Grain Boundary Crystallography Revealed by Experiment and Atomistic Simulation

Advanced Engineering Materials, EarlyView.
Grain boundary triple junctions are an essential ingredient of the microstructure of polycrystalline materials. In this study, a triple junction is observed using atomic‐resolution scanning transmission electron microscopy and characterized. Computer simulations reveal that the junction has a dislocation character that is determined by the joining ...

Corrosion fatigue crack propagation of AISI 316L by nitrogen ion implantation in simulated body fluid

Metalurgija, 2021
A thin layer was formed on the surface of the AISI 316L substrate by the process of nitrogen ion implantation at a vacuum pressure of 10-6 torr, a current of 50 mA for 90 minutes with the implantation energy of 20, 40 and 60 keV.
