Geometrical Designs in Volumetric Bioprinting to Study Cellular Behaviors in Engineered Constructs
Advanced Healthcare Materials, Volume 15, Issue 6, 9 February 2026.Curvature and spatial confinement guide cell behavior in volumetrically printed 3D constructs. Endothelial cells align and spread along specific geometries, while metastatic osteosarcoma cells proliferate independently of structural cues. Label‐free holographic microscopy captures real‐time, long‐term cell–material interactions, highlighting Gel‐PEG's ...

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Advanced Science, Volume 13, Issue 7, 3 February 2026.This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...

Stamping Lithography on Arbitrary Surfaces based on Self‐Assembly of Colloidal Particles
Advanced Science, Volume 13, Issue 9, 13 February 2026.A new method called Stamping Lithography for three‐dimensional (3D) circuits manufacturing is proposed, which comprises a resist mask stamping process based on self‐assembly of colloidal particles and a subsequent etching process. It replaces the photoresist with self‐assembled particles and the exposure process with stamping, making it feasible to ...

No News Is Good News Testing Modality and Redundancy in Immersive Augmented Reality
Journal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.ABSTRACT Background The modality and redundancy principles are well‐established within the cognitive theory of multimedia learning for their effectiveness in traditional media. However, previous studies applying these principles in virtual reality have shown contradictory results when immersive technologies are involved.

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 ...

Nanophotonics, Volume 15, Issue 3, 12 February 2026.This work proposes OAM‐encoded CNN based on cascaded on‐chip OAM converters and multiplexers. The footprint of inverse‐designed converters is 5 μm × 4 μm and the maximum conversion efficiency of OAM reaches 88%. The OAM‐encoded optical CNN was built using this device, achieving 98.0% accuracy on MNIST and 86.1% accuracy on Fashion‐MNIST classification.
