Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Reaction rates and transport in neutron stars

open access: yes, 2018
Understanding signals from neutron stars requires knowledge about the transport inside the star. We review the transport properties and the underlying reaction rates of dense hadronic and quark matter in the crust and the core of neutron stars and point ...

Delta isobars in neutron stars

open access: yesEPJ Web of Conferences, 2015
The appearance of delta isobars in beta-stable matter is regulated by the behavior of the symmetry energy at densities larger than saturation density. We show that by taking into account recent constraints on the density derivative of the symmetry energy

Chemical Doppelgangers in GALAH DR3: The Distinguishing Power of Neutron-capture Elements among Milky Way Disk Stars

open access: yesThe Astrophysical Journal
The observed chemical diversity of Milky Way stars places important constraints on Galactic chemical evolution and the mixing processes that operate within the interstellar medium. Recent works have found that the chemical diversity of disk stars is low.

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

open access: yesAdvanced Materials Interfaces, EarlyView.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...

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 ...

NEUTRON RICH NUCLEI AND NEUTRON STARS [PDF]

open access: yesFission and Properties of Neutron-Rich Nuclei, 2013
The PREX experiment at Jefferson Laboratory measures the neutron radius of 208Pb with parity violating electron scattering in a way that is free from most strong interaction uncertainties. The 208Pb radius has important implications for neutron rich matter and the structure of neutron stars.
