Modular and Automated Workflow for Streamlined Raman Signal Analysis

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 360-377, February 2026.
This study presents an automated workflow for preprocessing and analyzing Raman spectroscopy data, addressing key challenges such as noise suppression, baseline correction, and peak fitting using Voigt profiles. The method is validated on both synthetic and experimental spectra, demonstrating improved spectral fidelity and peak detection for biomedical

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 227-238, February 2026.
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Highly Selective Photocatalytic Degradation of Organic Pollutants by ZnO@C Core–Shell Nanoparticles Via Superoxide Radical Pathway

Small, Volume 22, Issue 8, 6 February 2026.
This study investigates a novel two‐step synthesis of ZnO@C nanoparticles (NPs), featuring enhanced photocatalytic dye degradation via selective superoxide (O2•−) radical generation under visible light. The precisely engineered carbon shell uniquely improves light–matter interaction and visible‐light absorption, as well as facilitates efficient charge ...

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.

Incorporation of Transition Metal Substituents Into LaNiO3 Improves Electrocatalytic Activity and Stability of Acidic Oxygen Evolution

Small Structures, Volume 7, Issue 2, February 2026.
Using high‐throughput synthesis and characterization techniques to significantly improve activation and stabilization of LaNiO3 for the oxygen evolution reaction in acidic conditions by substitution of the Ni (B site cation) with three other cations, namely, Mo, W, and Mn, that expand the crystal lattice structure.

Rigidity of anti‐de Sitter (2+1)‐spacetimes with convex boundary near the Fuchsian locus

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We prove that globally hyperbolic compact anti‐de Sitter (2+1)‐spacetimes with a strictly convex spacelike boundary that is either smooth or polyhedral and whose holonomy is close to Fuchsian are determined by the induced metric on the boundary.

Ricci solitons of special Lorentzian Lie groups with a four-dimensional isometry group

In the framework of the study of homogeneous Lorentzian three-manifolds, we consider here the only class of examples which admit a four-dimensional group of isometries but are neither Lorentzian Bianchi-Cartan-Vranceanu spaces nor plane waves. We obtain an explicit description in global coordinates of these special homogeneous Lorentzian manifolds.
