Effect of Pulse Electrodeposition Parameters on the Microstructure and Mechanical Properties of Ni–W/B Nanocomposite Coatings

Nanomaterials, 2022
In this work, Ni–W/B nanocomposite coatings were successfully fabricated on low carbon steel by using pulse current (PC) electrodeposition. The effects of the frequency and duty cycle on the microstructure, wear resistance, and microhardness of the ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Generalized Finslerian Wormhole Models in $f(\mathcal{R},\mathcal{T})$ Gravity

Particles
This article explores wormhole solutions within the framework of Finsler geometry and the modified gravity theory. Modifications in gravitational theories, such as f(R,T) gravity, propose alternatives that potentially avoid the exotic requirements.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Conditions of energy efficient behaviour - a comparative study between Sweden and the UK

, 2010
The main aim of this study is to compare how specific conditions in certain countries (in this case, the UK and Sweden) can stimulate or oblige householders to be more energy efficient, or can obstruct this.

Effect of substitution on the superconducting phase of transition metal dichalcogenide Nb(Se $$_{x}$$ x S $$_{1-x}$$ 1 - x ) $$_{2}$$ 2 van der Waals layered structure

Scientific Reports, 2021
By means of first-principles cluster expansion, anisotropic superconductivity in the transition metal dichalcogenide Nb(Se $$_{x}$$ x S $$_{1-x}$$ 1 - x ) $$_{2}$$ 2 forming a van der Waals (vdW) layered structure is observed theoretically.

Energy conditions and quantum information

Canadian Journal of Physics
The concept of energy lies at the foundation of physical science. In general relativity and quantum field theory, the positivity and conservation of energy are encapsulated by the so-called energy–momentum tensor and the energy conditions. In recent efforts to unify fundamental physics with quantum information, the energy conditions have come to play a
