Recent Advances in PVA‐Based Humidity Sensors: Materials Design and Future Prospects

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Polyvinyl alcohol‐based humidity sensing materials, highlighting pristine PVA, polymer blends, and organic/inorganic composites for enhanced sensing performance. ABSTRACT Polyvinyl alcohol (PVA) and its derivatives have gained considerable attention for humidity‐sensing applications due to their hydrophilic nature, excellent film‐forming ability, and ...

Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

Carbon and Hydrogen, Volume 28, Issue 2, Page 196-208, June 2026.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Biconical antennas with elliptical cross-sections

Electronics Letters, 2000
The methods of coordinate transformation and conformal mapping are applied to study the problem of radiation from a biconical antenna with elliptic cross section. The infinite elliptic cone geometry can be transformed into the two-dimensional plane under the assumption of pure TEM spherical waves.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, Volume 36, Issue 42, 26 May 2026.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Single and Multiple Scattering in UWB Bicone Arrays

International Journal of Antennas and Propagation, 2008
An analysis of interactions between radiators in a UWB biconical array, drawing attention to single and multiple scatterings, is carried out. The complementarity between electrical coupling and radiation scattering is argued.

A High‐Resolution Transcriptomic Atlas of Cell Types in the Ventral Visual Thalamus

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Visual information from the eyes travels from retinal ganglion cells (RGCs) to reach the brain through several relay centers. One of these centers, the ventral lateral geniculate nucleus (vLGN), is much less understood than others. In this study, we created the first detailed map of the different cell types found in the mouse vLGN.

Drelów, the 13th and latest meteorite fall in Poland—A typical L6 chondrite with shock veins

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 466-486, March 2026.
Abstract On Tuesday, February 18, 2025, at 18:04:14 local time, residents of Poland observed a bright fireball registered by many Polish fireball stations belonging to the Skytinel Network established a few months before by Mateusz Żmija. Thus, the meteoroid's orbit, atmospheric trajectory, and the strewn field were calculated, and over 70 fragments ...

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, Volume 36, Issue 15, 19 February 2026.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Kindberg, the fifth meteorite fall in Austria: A weakly shocked L6 chondrite breccia with high‐pressure phases

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 17-38, January 2026.
Abstract A bright fireball was seen at 4:46 a.m. CET on November 19, 2020, over Austria, and also eye witnessed in Italy and Germany. The resulting Kindberg meteorite was the fifth well‐approved meteorite fall in Austria, and all rocks represent ordinary chondrites.
