Full‐Spectrum Solar Harvesting and Desalination Enabled by Supra‐Nano Amorphous Ruthenium Dioxide – Mineral Composites

open access: yesAdvanced Functional Materials, EarlyView.
A mineral‐based supra‐nano amorphous ruthenium dioxide composite (a‐Ru0.5‐AM) was designed, achieving 97% broadband solar absorption. Under one sun, it reaches 87.91 ± 0.32 °C with a distinct thermal buffering effect that favors thermal confinement.

Ultra‐Sensitive Short‐Wave Infrared Organic Photodetectors Enabled by a π‐Conjugation Extended Proquinoid Electron Acceptor

open access: yesAdvanced Functional Materials, EarlyView.
A novel proquinoid‐type electron acceptor, TQC‐4Cl, with an ultra‐narrow bandgap of 1.01 eV and spectral response beyond 1200 nm enables organic SWIR photodetectors. The optimized devices show a high EQE of 13.66% and high specific detectivity over 1012 Jones at 1200 nm under −0.5 V reverse bias with outstanding thermal stability, highlighting their ...

Advances in Stimuli‐Responsive Organic Materials and Polymers toward Intelligent CO2 Capture

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of the relationship between different stimuli and stimuli‐responsive organic materials and polymers for carbon dioxide (CO2) capture. Main stimuli include redox, pH, magnetism, temperature, light, and pressure. Furthermore, multi‐responsive materials, due to their high adaptability and scalability in complex environments, are ...

Mapping the Dense Molecular Gas toward 13 Supernova Remnants

open access: yesThe Astrophysical Journal
Supernova remnants (SNRs) can exert strong influence on molecular clouds (MCs) through interaction by shock wave and cosmic rays. In this paper, we present our mapping observation of HCO ^+ and $\mathrm{HCN}$ 1–0 lines toward 13 SNRs interacting with MCs,

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

open access: yesAdvanced Functional Materials, EarlyView.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Novel Bioconjugate Materials: Synthesis, Characterization and Medical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses the bioconjugation of novel materials grouped under “biological”, “hybrid” and “synthetic” categories. Medical applications ranging from cancer therapy and diagnostics to optogenetics and tissue engineering are explored, and conjugation trends are highlighted as a general guide. The review concludes with a comparison of techniques

Tidal Disruption of “Snow Clouds” by Unassociated Stars

open access: yesThe Astrophysical Journal
It has been suggested that star-forming galaxies may host a substantial, dark reservoir of gas in the form of planetary-mass molecular clouds that are so cold that H _2 can condense.
