Multichannel Photoluminescence of Graphene Quantum Dots Across Femtosecond to Cryogenic Timescales
This study reveals how graphene quantum dots emit light across all relevant timescales, from femtoseconds to cryogenic steady states. By integrating optical Kerr gating, time‐correlated single‐photon counting, and low‐temperature photoluminescence, distinct intrinsic, surface, and defect‐related emission channels are temporally and spectrally ...

A highly conformal and adhesive dry electrode is developed using a micro‐textured carbon black/PDMS composite. By leveraging spontaneous surface roughness for enhanced mechanical interlocking and integrating a stretchable serpentine interconnector, the device achieves robust skin contact and low impedance.

Abstract The world is experiencing a biodiversity crisis. Steep declines in habitat quality and ecosystem services have resulted in interest in markets to help fund ecological restoration. One way that ecological restoration is assessed is through indicators of ecosystem condition, namely, a measurement of how different a landscape is from its ...

neonSoilFlux: An R package for continuous sensor‐based estimation of soil CO2 fluxes
Abstract Accurate quantification of soil carbon fluxes is essential to reduce uncertainty in estimates of the terrestrial carbon sink. However, these fluxes vary over time and across ecosystem types and so, it can be difficult to estimate them accurately across large scales.

ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt
Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.
