Interface Engineering of Porous Transport Layer‐Catalyst Layer in Proton Exchange Membrane Water Electrolyzers: A Comprehensive Review

open access: yesAdvanced Materials Interfaces, EarlyView.
The PTL–CL interface plays a decisive role in PEMWE performance by governing electron conduction, water supply, oxygen removal, catalyst utilization, and interfacial stability. This review summarizes interface‐related resistance sources, characterization methods, and engineering strategies, highlighting rational PTL–CL interface design for low‐cost ...

Advances in Halide Perovskites for Photon Radiation Detectors

open access: yesAdvanced Materials Technologies, EarlyView.
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Equilibria and oscillations of magnetised neutron stars

open access: yes, 2010
We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

The compact neutron star in 4U 1746-37 revisited: Reassessing the mass and radius

open access: yesAstronomy & Astrophysics
Context. A recent analysis of photospheric radius expansion X-ray bursts from the low-mass X-ray binary 4U 1746-37 reported unusually small mass and radius estimates for the neutron star, suggesting it could be a quark star or quark-cluster star.

Constraints on Microscopic and Phenomenological Equations of State of Dense Matter from GW170817

open access: yesUniverse, 2019
We discuss the constraints on the equation of state (EOS) of neutron star matter obtained by the data analysis of the neutron star-neutron star merger in the event GW170807.

Neutron-star matter within the energy-density functional theory and neutron-star structure

open access: yes, 2015
In this lecture, we will present some nucleonic equations of state of neutron-star matter calculated within the nuclear energy-density functional theory using generalized Skyrme functionals developed by the Brussels-Montreal collaboration.

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

open access: yesAdvanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Neutron star merger remnants [PDF]

open access: yesGeneral Relativity and Gravitation, 2020
AbstractBinary neutron star mergers observations are a unique way to constrain fundamental physics and astrophysics at the extreme. The interpretation of gravitational-wave events and their electromagnetic counterparts crucially relies on general-relativistic models of the merger remnants.
