Measuring Molecular Forces With Atomic Force Microscopy 1: Solvent Influence on Hydrophobic Interactions

open access: yesMicroscopy Research and Technique, Volume 89, Issue 5, Page 718-726, May 2026.
Atomic force microscopy enables precise evaluation of the magnitude and range of hydrophobic and van der Waals interactions. This primer presents a protocol for fluorocarbon functionalization of gold surfaces and examines how water: DMSO mixtures affect hydrophobic forces, with data interpreted through an extended van der Waals model.

Prospective Environmental Impact Assessment of Scaling Up Perovskite/Silicon Tandem Solar Cells to Industrial Applications

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
This prospective life cycle analysis evaluates perovskite–silicon (PSC–Si) tandem solar cells (TSCs), assessing environmental impacts from their material extraction to end‐of‐life. We compare the environmental impact of four TSC designs with that of silicon PV, highlighting hotspots in tandem architecture, and explore strategies to reduce environmental

Laser‐Enabled Nanopinholes for Silicon Solar Cells with Polycrystalline Si/SiOx Passivating Contacts

open access: yesSolar RRL, Volume 10, Issue 8, 27 April 2026.
Conductive nanoscale pinholes are created by selective heating of pyramid tips on randomly textured silicon via pulsed laser irradiation. Due to heat concentration at the pyramid tips, the dielectric passivating layer is selectively opened at the pyramid tips.

A Distributed Bragg Reflector Interface for Filter‐Free Fluorescence Spectro‐Microscopy With High Spectral Tunability

open access: yesphysica status solidi (a), Volume 223, Issue 8, 22 April 2026.
An all‐dielectric TiO2/SiO2 distributed Bragg reflector is engineered as a substrate‐integrated optical filter, enabling filter‐free fluorescence spectro‐microscopy. Nanometer‐scale layer control aligns excitation suppression and emission reflection for specific fluorophores, achieving high‐contrast imaging at sub‐monolayer coverage.
