The Hydrogen Clouds in the Galactic Halo [PDF]
Symposium - International Astronomical Union, 2004 New 21cm observations with the Green Bank Telescope show that a significant fraction of the HI in the inner Galaxy's halo ~ 1 kpc from the midplane exists in the form of discrete clouds. Some look very much like a Spitzer (1968) “standard” diffuse cloud but with their HI in two phases.

Exploring Double NDR Modulation and UV‐NIR Photodetection in MoS2/Sb2Se3 Heterostructures
Advanced Optical Materials, EarlyView.In this study, a van der Waals Sb2Se3/MoS2 heterostructure exhibits dual negative differential resistance (NDR) peaks at room temperature. The first originates from band‐to‐band tunneling, while the second, triggered under laser illumination, is attributed to trap states and recombination dynamics.

Two views of globular cluster stars in the Galactic halo
EPJ Web of Conferences, 2012 In [1] we reported the discovery in the Sloan Digital Sky Survey-II/SEGUE spectroscopic database of a small subset of halo red giants, 2.5%, with CN and CH band strengths indicative of globular-cluster-like carbon and nitrogen abundances.

Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials
Advanced Optical Materials, EarlyView.Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
Advanced Optical Materials, EarlyView.A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

Advanced Optical Materials, EarlyView.A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...
