Dual‐Wavelength Switchable Focusing via a Fabry‐Pérot Resonance‐Enabled Hydrogel Metalens

Advanced Physics Research, EarlyView.
A hydrogel metalens is demonstrated for dual‐wavelength switchable focusing based on Fabry‐Pérot resonance. Under the low relative humidity, the metalens exclusively focuses light with a resonance wavelength of 470 nm and directly reflects light of other wavelengths.

Light‐Responsive Carbon Dots with Photochromism and Excitation‐Dependent Room Temperature Phosphorescence

Advanced Physics Research, EarlyView.
A light‐responsive system with photochromism and excitation‐dependent phosphorescence was constructed by microwave synthesis of nitrogen‐doped carbon dots(N‐CDs), which provides insights into the design and synthesis of CDs with multifunctional optical properties, promoting the application expansion of intelligent responsive materials in the fields of ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit

Astronomische Nachrichten, EarlyView.
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...
