Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites
Advanced Materials Technologies, EarlyView.Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Polarized equatorial emission and hot spots around black holes with a dark matter halo
European Physical Journal C: Particles and FieldsWe study linear polarization of the accretion disks around black holes with a dark matter halo. The interaction of the black hole with the dark matter is modeled by considering an exact solution to the Einstein equations which describe a superposition of

Chiral Porphyrin Monolayers on Ferromagnetic Thin Films: Ultrafast Spectroscopy of Hybrid Interfaces
Advanced Optical Materials, EarlyView.Chiral porphyrin–oligopeptide monolayers covalently bound to Au‐capped Co/Ni multilayers form surface‐parallel J‐type aggregates and exhibit measurable singlet‐state transient absorption despite monolayer coverage. Femtosecond pump–probe spectroscopy reveals strong excited‐state quenching at the metal interface, yet no long‐lived charge‐transfer ...

C-19 and Hot, Wide Star Streams
The Astrophysical JournalThe C-19 star stream has the abundance characteristics of an unusually metal-poor globular cluster but kinematically is uncharacteristically hot and wide for a cluster stream, having a line-of-sight velocity dispersion of 7 ± 2 km s ^−1 and a 1 σ width

Cosmology: What One Needs to Know
Zygon, 2000 Cosmology, the study of the universe, has a past, which is reviewed here. The standard model—the Big Bang, or the hot, dense early universe that is still expanding—is based on observations that are basically consistent but which require additional input

Constraints on massive neutrinos as hot dark matter
Nuclear Physics B - Proceedings Supplements, 1996 This article highlights three astronomical observations that can constrain the masses of neutrinos as hot dark matter: high-redshift damped Lyα systems, the cosmic microwave background anisotropy, and gravitational lenses. Theoretical predictions and current constraints are summarized.
