Generalized Helical Hypersurface with Space-like Axis in Minkowski 5-Space

Universe, 2023
We introduce the generalized helical hypersurface having a space-like axis in five-dimensional Minkowski space. We compute the first and second fundamental form matrices, Gauss map, and shape operator matrix of the hypersurface.

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth

New Phytologist, Volume 250, Issue 4, Page 2384-2398, May 2026.
Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

Small, Volume 22, Issue 7, 2 February 2026.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes

Advanced Functional Materials, Volume 36, Issue 7, 22 January 2026.
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...

Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

physica status solidi (b), Volume 263, Issue 1, January 2026.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale

Reaction between the Ionic Liquid BMP‐TFSI and Li: Comparison between Monolayer Films and Thick Multilayer Films on Graphite (0001)

Batteries &Supercaps, Volume 8, Issue 11, November 2025.
Model studies can reveal the chemical processes contributing to the formation of the solid electrolyte interphase in batteries. Employing X‐Ray photoelectron spectroscopy measurements and density functional theory calculations, it is shown that the steps in the reaction between Li and an ionic liquid (BMP‐TFSI) adsorbed on graphite can be highly ...

Asymptotics of quantum 6j$6j$‐symbols and generalized hyperbolic tetrahedra

Journal of Topology, Volume 18, Issue 3, September 2025.
Abstract We establish the geometry behind the quantum 6j$6j$‐symbols under only the admissibility conditions as in the definition of the Turaev–Viro invariants of 3‐manifolds. As a classification, we show that the 6‐tuples in the quantum 6j$6j$‐symbols give in a precise way to the dihedral angles of (1) a spherical tetrahedron, (2) a generalized ...
