Noise Suppression in Organic Photodiodes: A Comprehensive Review of Mechanistic Insights and Design Principles

open access: yesSmall, Volume 22, Issue 3, 13 January 2026.
Organic photodiodes are limited by dark current and excess low‐frequency noise. This review synthesizes mechanisms of noise, links to three leakage pathways, and unifies measurement practice with device design. By outlining energetics, morphology, and interface strategies, it provides validated routes to lower noise floors and higher detectivity across

Coercivity‐Size Map of Magnetic Nanoflowers: Spin Disorder Tunes the Vortex Reversal Mechanism and Tailors the Hyperthermia Sweet Spot

open access: yesSmall Science, Volume 6, Issue 1, January 2026.
Large‐scale micromagnetic simulations show how disorder and grain boundaries control magnetization dynamics in iron‐oxide nanoflowers beyond the single‐domain regime. Two competing vortex‐reversal modes emerge, producing a coercivity maximum at their transition.

On‐Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography

open access: yesSmall Methods, Volume 10, Issue 2, 22 January 2026.
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.

The Dual Role of Antimony in Enhancing the Durability of Bismuth‐Based CO2 Reduction Gas Diffusion Electrodes

open access: yesSmall Structures, Volume 7, Issue 1, January 2026.
Bismuth‐based gas diffusion electrodes have demonstrated the ability to efficiently convert CO2 into formate. However, their stability is compromised by product‐induced corrosion. By adding just 10–15%at. of antimony, the operational stability is increased sixfold, which can be attributed to two main factors: first, the addition enhances corrosion ...

A Comparative Analysis of Intratesticular Versus Intra‐Epididymal Injections of Clove Essential Oil on Male Dog Sterilization

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study evaluated clove essential oil as a non‐surgical sterilant in male dogs. Both intratesticular and intra‐epididymal injections significantly reduced sperm concentration, motility and viability, with histological and sonographic evidence of reproductive tissue damage.

Increasing the Accuracy and Efficiency of Micromagnetic Tomography by Double Sided Scanning

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Paleomagnetic data are usually retrieved by subjecting bulk samples, for example lavas, to laboratory measurement protocols. In many instances, the data related to these protocols yield uninterpretable results caused by the presence of particles with adverse magnetic properties that blur the signal of the reliable magnetic particles.
