Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors

open access: yesAdvanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

Geological Mapping and Structural Analysis of the Western Half of the Eminescu Quadrangle (H09), Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.

Understanding the Influence of Soil Moisture on Machine Learning Predictions of Photosynthesis and Evapotranspiration

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Evapotranspiration (ET) and photosynthesis are key processes in ecosystem functioning on which soil moisture (SM) has an important influence. Eddy covariance measurements and machine learning (ML) increasingly enable flux prediction in ungauged regions.

Enhanced Photoelectrochemical Activity by Nickel Oxide: Laser‐Based Smart Fabrication From Powders and Decoration of Titania Nanotubes

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 5, May 2026.
A target composed of pressed nickel powders is used for laser ablation, as alternative to bulk nickel, with a study on optimal fluence. Produced NiO NPs are used for decoration of laterally spaced titania nanotube, fabricated by anodization of titanium foil and calcination in air.
