Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, EarlyView.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Unexpected Sign Inversion of the Circular Dichroism and Circularly Polarized Luminescence Response of Chiral Copolymer Thin Films by Tuning the Thickness and Annealing Conditions

ChemPhotoChem, EarlyView.
Copolymer thin films with induced supramolecular chirality show promise for chiroptical optoelectronic applications. Sign changes of the strong circular dichroism and circularly polarized luminescence (CPL) of such films are demonstrated by tuning their film thickness and annealing conditions.

Modulation of Self‐Assembly and Enhanced Photocatalytic H2 Production by Porphyrin‐Dipeptide Conjugates

ChemSusChem, EarlyView.
Self‐assembled peptide–porphyrin conjugates are shown to produce green hydrogen under visible light irradiation. The morphology of the nanostructures, which can be tuned, directly influences catalytic activity. Among the architectures formed, tubular assemblies display the highest efficiency, offering a promising strategy for light‐driven hydrogen ...

Flexible Chromatic VIS‐IR Meta‐Textile for Multi‐Scenario Stealth

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A flexible chromatic meta‐textile was developed for multi‐spectral stealth across VIS‐IR bands, combining low color difference, ultralow infrared emissivity, and passive radiative cooling. The textile exhibits excellent VIS wide‐angle compatibility, optical durability, and mechanical flexibility, offering a promising solution for advanced stealth ...

Enabling flexible, wearable, and implantable electronics with radio frequency‐based wireless charging: Fundamentals, challenges, and emerging applications

FlexMat, EarlyView.
This paper presents a comprehensive review of radio frequency (RF)‐based wireless charging technologies for flexible electronics. In particular, we (i) provide an overview of wireless charging approaches, (ii) investigate the fundamental RF charging principles, covering rectenna design, impedance matching, RF‐to‐DC conversion, and power management, and
