Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing

open access: yesLaser &Photonics Reviews, EarlyView.
Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

Influence of Viscosity Ratio on the Mechanical, Morphological, and Rheological Properties of Thermoplastic Dynamic Vulcanizates from Devulcanized Tire Rubber and Polypropylene

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study explores how polypropylene viscosity influences the structure and performance of thermoplastic dynamic vulcanizates made with devulcanized tire rubber. Higher matrix viscosity results in better dispersion of the rubber phase, forming smaller domains and enhancing mechanical properties. The findings support more efficient recycling strategies

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

open access: yesMass 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).
