Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

Small, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Mode and Polarization Division Multiplexing Based on Chalcogenide‐Glass‐on‐Thin‐Film Lithium Niobate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
High‐index GeSbSe chalcogenide glass loaded on thin‐film lithium niobate enables compact broadband mode‐ and polarization‐division multiplexing. Exploiting direction‐dependent birefringence of x‐cut LNOI, a four‐channel mode (de)multiplexer and asymmetric directional coupler‐based polarization splitter–rotator are demonstrated with great performance in
