Digital Preservation and Astronomy: Lessons for funders and the funded
, 2011 Astronomy looks after its data better than most disciplines, and it is no coincidence that the consensus standard for the archival preservation of all types of digital assets -- the OAIS Reference Model -- emerged originally from the space science ...

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Advanced Optical Materials, EarlyView.The excitation of a transition‐metal azo Schiff‐base complex with a 1064 nm laser induces a series of nonlinear optical effects. These effects include the second harmonic generation at 532 nm and third harmonic generation at 355 nm. This process demonstrates the potential of the complex for high‐order nonlinear optical applications. Abstract This paper

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.

Advanced Optical Materials, EarlyView.Polaritons, or hybridized excitations of light and matter, have been recently discovered in high‐quality freestanding oxide membranes of perovskite oxides like SrTiO3 grown by hybrid molecular beam epitaxy. This work finds that hybridization of polaritons across membrane interfaces produces waves with simultaneously tunable positive and negative group ...
