Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.

High energy gamma ray astronomy [PDF]

High energy gamma ray astronomy has evolved with the space age. Nonexistent twenty-five years ago, there is now a general sketch of the gamma ray sky which should develop into a detailed picture with the results expected to be forthcoming over the next ...

Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...

Spectroscopic Investigations on Polyvinylidene Fluoride Nanofibers

Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.
The fabrication of Polyvinylidene fluoride nanofibers from solution by force‐spinning is reported. Polymer mats were obtained at spinning rates ranging from 4000 to 10 000 rotations per minute. Raman and X‐ray data confirm the dominant α phase with a small admixture of β. The β‐phase content increases from 15% to over 70% as the spinning rate increases.

TeV Analysis of a Source-rich Region with the HAWC Observatory: Is HESS J1809-193 a Potential Hadronic PeVatron?

The Astrophysical Journal
HESS J1809-193 is an unidentified TeV source, first detected by the High Energy Stereoscopic System (H.E.S.S.) collaboration. The emission originates in a source-rich region that includes several supernova remnants (SNRs) and pulsars including SNR G11.1 ...

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...
