Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant [PDF]

open access: yes, 2010
We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke that the thermal radiation of this star is well described by a carbon atmosphere model and the emission comes from the ...

Emergent Spin Supersolids in Frustrated Quantum Materials

open access: yesAdvanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.

Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites

open access: yesAdvanced Materials, EarlyView.
Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

Neutron/Gamma Mixed Spectrum Radiolysis-based Aqueous Dosimetry [PDF]

open access: yes, 2007
This work develops a method to use an aqueous dosimeter in a mixed radiation field to determine separate measurements of neutron and gamma dose. Based on radiolysis of both Fricke and Methyl Viologen (MV) solutions, activation analysis and reactor ...

Delayed Thermal Relaxation of Rapid Cooling Neutron Stars: Nucleon Superfluidity and Nonnucleon Particles

open access: yesThe Astrophysical Journal
The thermal relaxation time of neutron stars, typically defined by a sudden drop in surface temperature, is usually on the order of 10–100 yr. In this study, we investigate neutron star thermal relaxation by incorporating nucleon superfluidity and ...

Effect of temperature history on swelling behavior of V-Fe binary alloy irradiated in a fast reactor Joyo

open access: yesNuclear Materials and Energy, 2020
An on-line instrumented material irradiation rig (MARICO-II) was used for investigating temperature history effect for void swelling behavior in V-Fe binary alloys irradiated at a fast rector, Joyo. Neutron irradiation were performed at 477C with 7.5 dpa

Robust Spin Splitting and Fermiology in the Layered Altermagnet CoNb4${\rm CoNb}_4$Se8${\rm Se}_8$

open access: yesAdvanced Materials, EarlyView.
The emergence of an altermagnetic phase is demonstrated in the cobalt‐intercalated superconducting 2H‐NbSe2 polymorph. A combined theoretical and experimental approach directly probes the magnetism, the altermagnetic lifting of Kramers degeneracy, and the electronic phase space, establishing CoNb4Se8 as the first g‐wave altermagnetic layered material ...

Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

open access: yesAdvanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...
