Meniscus‐Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra‐Stiff 15 MHz MEMS AFM Probes

open access: yesJournal of Molecular Recognition, Volume 39, Issue 3, May 2026.
ABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

open access: yesAdvanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...

Hybrid GRA–Machine Learning Framework for Surface and Performance Optimization of Ti49.3Ni50.7 SMA in Biomedical Applications

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
Ti49.3Ni50.7 shape memory alloy is highly biocompatible but difficult to machine due to its complex thermo‐mechanical behavior. An enhanced Wire EDM process was developed using a Taguchi L18 design, GRA, and Random Forest with Bayesian optimization. The optimized parameters achieved a surface roughness of 1.298 μm and a material removal rate of 2.537 ...

Roll‐to‐Roll Mechanical Exfoliation for Large‐Area van der Waals Films with Preserved Crystallographic Alignment

open access: yesAdvanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
A roll‐to‐roll exfoliation method is demonstrated that preserves the crystallographic alignment of anisotropic 2D materials over large areas, enabling scalable fabrication of directional electronic and optoelectronic devices. Abstract Anisotropic 2D materials such as black phosphorus (BP), GeS or CrSBr, exhibit direction‐dependent optical and ...
