Tin‐based perovskite light‐emitting diodes: Progress and perspective

open access: yesInfoScience, EarlyView.
This review assesses tin‐based perovskite light‐emitting diodes (PeLEDs), focusing on the limitations of Sn2+ oxidation–induced defects and uncontrolled crystallization. By evaluating advanced device engineering and structural innovations, this article highlights their viability in narrowband pure‐red displays and near‐infrared optical communication ...

Preparation of cu/fes nanoparticles by mechanochemical reduction of copper sulphide

open access: yes, 2002
The mechanochemical reduction of copper sulphide with elemental iron was studied. The methods of XPS, SEM, EDX, and low temperature nitrogen sorption were used to analyse the surface composition and the composite particles formed from elemental copper ...

Ultrasound‐Assisted Epoxy Resin Curing Monitored by Impedance Spectroscopy

open access: yesPolymer Engineering &Science, EarlyView.
Ultrasound enhances epoxy cure rates via localized heating without altering cure kinetics. Impedance spectroscopy provides a direct, non‐destructive measure of cure progression, enabling accurate mapping of degree of cure in real time. ABSTRACT Epoxy resins are widely used in aerospace and automotive manufacturing as structural adhesives and matrices ...

Improved Stability in LiX‐NbCl5 (X = Cl, Br) Glass‐Ceramic Electrolytes Through Anion Mixing for Solid‐State Batteries

open access: yesSmall, EarlyView.
Chlorine gas evolves at the end of charge in solid‐state batteries with LiNbCl5X (X = Cl−, Br−) catholytes. This can be mitigated to some extent by introducing bromine and has a positive effect on electrochemical stability but does not impair ionic conductivity.

Predicting the Regioselectivity of Mechanochemical Bond Scission in Complex Molecules

open access: yesTransformative Chemistry, EarlyView.
Covalent‐bond peak force network (CBPFNet), a physics‐informed graph attention framework, predicts mechanochemical bond scission regioselectivity directly from equilibrium structures with DFT‐level accuracy. By uncovering the ‘stiffness mismatch’ mechanism, this work enables the rational design of programmable mechanical fuses for next‐generation ...

Wavelength–angle characterization of high‐energy X‐ray beams from lapped Si(111) double‐crystal monochromators using rocking‐curve tomography

open access: yesJournal of Synchrotron Radiation, EarlyView.
A computed‐tomography method using full‐rotation rocking curves is developed to characterize 100 keV X‐ray beams from lapped Si(111) crystals, revealing systematic wavelength broadening while maintaining constant angular divergence in DuMond space.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator (DCM) has recently been shown ...

Fish welfare in a changing world: New developments and current challenges

open access: yesJournal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia
