A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

open access: yesAPL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...

Vortex creep heating vs. dark matter heating in neutron stars

open access: yesPhysics Letters B
Dark matter particles captured in neutron stars deposit their energy as heat. This DM heating effect can be observed only if it dominates over other internal heating effects in neutron stars. In this work, as an example of such an internal heating source,

Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

open access: yesAdvanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Effect of Neutron Irradiation on Transformation Temperatures of nearly Equi-Atomic Nitinol Alloys

open access: yes, 2000
The effect of neutron irradiation on shape memory alloys has been studied using electrical resistance measurements. The martensitic transformation start temperature (Ms) and the austenite start temperature (As) decreased markedly with increasing the ...

Neutron Scattering Studies on Singlet Magnetic Ground State Systems [PDF]

open access: yes, 2005
An energy gap or "pseudogap", where there is spin pairing without phase coherence, has been observed in a number of unconventional superconductors that has been detected even above the superconducting transition.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Ethane as a Neutron Moderator at Cryogenic Temperatures

open access: yesEPJ Web of Conferences
The study’s objective is to examine the neutron temperature response, using liquid and solid ethane at various cryogenic temperatures to evaluate the effectiveness of ethane as a cold neutron moderator in compact moderator systems. The experimental measurements were carried out at temperatures of 170 K, 135 K, 100 K, 70 K, 50 K, 25 K, 15 K, and 10 K ...

Sulfide‐Based Electrolytes for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review covers the structural features and synthesis strategies of sulfide‐based solid electrolytes, as well as critical challenges related to conductivity, interfacial and moisture stability, and scaling‐up for practical application in Sodium‐based All Solid‐State Batteries.

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Modulating the Swelling Behavior of Polymer Brushes via Interfacial Chemistry

open access: yesAngewandte Chemie, EarlyView.
Modulating substrate surface chemistry of surface‐grafted polymer brushes via variation of the chemical composition of spacers that anchor initiators for surface‐initiated atom transfer polymerizations allows to tune swelling of these thin polymer films.
