Galactic Open Clusters [PDF]

open access: yes, 2005
The study of open clusters has a classic feel to it since the subject predates anyone alive today. Despite the age of this topic, I show via an ADS search that its relevance and importance in astronomy has grown faster in the last few decades than ...

Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications

open access: yesAdvanced Materials, EarlyView.
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Long‐Range Spin Transport in Chiral Gold

open access: yesAdvanced Materials, EarlyView.
It is demonstrated that in chiral gold film, spin information can be transferred to distances of several microns at room temperature. The conduction of spins is accompanied by the Hall effect that exists without applying an external magnetic field. The spin diffusion length is consistent with the frequency‐dependent Hall effect which indicates spin ...

Highly Efficient Platinum‐Free Photocatalytic Hydrogen Evolution From Low‐cost Conjugated Polymer Nanoparticles

open access: yesAdvanced Materials, EarlyView.
Platinum‐free hydrogen photocatalysis is achieved using dibenzothiophene‐S,S‐sulfoxide‐based conjugated polymers, self‐assembled into nanoparticles via nanoprecipitation. Through side chain engineering and donor–acceptor design, these materials reach a hydrogen evolution rate of 209 mmol g⁻¹ h⁻¹. The structure–function insights presented here establish
