Substrate‐Tight Graphene Transmembrane‐nanofluidic Devices

open access: yesSmall, EarlyView.
This study demonstrates that the covalent coupling of a pyrene layer to a silicon nitride substrate using silane and peptide chemistry increases the adhesion of graphene to the substrate and prevents the delamination of graphene. 76.2% of the devices with free‐standing graphene are successful devices for ion transport measurement in 0.1 M HCl ...

Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

open access: yesSmall, EarlyView.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...

Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

open access: yesSmall, EarlyView.
Sugar‐based fluorescent low‐molecular‐weight gelators (LMWGs) DNapS, DBTDS, and MCumS, prepared by a green, scalable route, form supramolecular gels in water, organic, and deep eutectic solvents. MCumS yields solvent‐dependent nanofibrous networks and viscoelastic injectable eutectogels.

Assessment of Soiling Dynamics and Cleaning Efficiency for Photovoltaic Modules Under Different Dust Environments

open access: yesSolar RRL, EarlyView.
A laboratory framework reproduces site‐specific soiling and cleaning dynamics of photovoltaic modules using real dusts from contrasting climates. Accelerated humidity–temperature cycling replicates 1 month of outdoor cementation in only ≈ 1.5 days.
