Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, Volume 22, Issue 43, 3 August 2026.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting

Small, Volume 22, Issue 46, 18 August 2026.
Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...

Application of Ag‐Enriched Nanostructures Through Ga+ Irradiation of Silver Butyrate Films in Surface‐Enhanced Raman Spectroscopy (SERS)

Small Methods, Volume 10, Issue 15, 7 August 2026.
We report a direct‐writing method for patterning silver‐enriched nanostructures with dual functionality: High electrical conductivity, with a resistivity of 95 µΩ·cm, and strong SERS activity, achieving enhancement factors exceeding 107. This approach enables an easy and cost‐effective alternative for the production of microstructures with applications

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.

Transient Ecological Niches for Diazotrophs in Upwelling Bays

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18
