A Label‐Free Ultraviolet Photoacoustic Microscopy Enables Nuclear Imaging and Toxicity Assessment in an Intact Brain Organoid

open access: yesSmall, Volume 22, Issue 51, 11 September 2026.
Ultraviolet photoacoustic microscopy enables label‐free visualization of nuclear morphology in intact human brain organoids. By exploiting endogenous nucleic acid absorption at 266 nm, this approach resolves individual nuclei without staining or sectioning.

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

open access: yesSmall, Volume 22, Issue 49, 1 September 2026.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

The Completion Rate of the Mid‐Trimester Fetal Anatomy Scan: A Clinical Audit

open access: yesSonography, Volume 13, Issue 3, September 2026.
ABSTRACT Introduction Auditing of imaging examinations for completion and quality assurance purposes is often utilized in diagnostic imaging, comparing the performance of examinations to accepted protocols. Clinical audits of the mid‐trimester anatomy ultrasound (AUS) can identify areas for improvement and training.
