Advanced Science, EarlyView.This study introduces a self‐powered environmental monitoring system that integrates a triboelectric nanosensor (TENS) with a robotic hand, controlled remotely by an exo‐hand and powered by a thermoelectric generator (TEG). The fully autonomous system detects Pb2⁺, Cr⁶⁺, and As3⁺ ions in real‐time and operates without external power, ideal for remote ...

Advanced Science, EarlyView.By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.

Groundwater flow across spatial scales: importance for climate modeling
Environmental Research Letters, 2014 Current regional and global climate models generally do not represent groundwater flow between grid cells as a component of the water budget. We estimate the magnitude of between-cell groundwater flow as a function of grid cell size by aggregating ...

One million year old groundwater in the Sahara revealed by krypton-81 and chlorine-36 [PDF]
, 2004 Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were performed by a new laser-based atom-counting method. 81Kr ages range from \~2x10^5 to ~1x10^6 yr, correlate with 36Cl/Cl ratios, and are consistent with lateral flow of groundwater from a recharge area near the Uweinat Uplift in SW Egypt.

Multi-scale Digital Twin: Developing a fast and physics-informed surrogate model for groundwater contamination with uncertain climate models [PDF]
arXiv, 2022 Soil and groundwater contamination is a pervasive problem at thousands of locations across the world. Contaminated sites often require decades to remediate or to monitor natural attenuation. Climate change exacerbates the long-term site management problem because extreme precipitation and/or shifts in precipitation/evapotranspiration regimes could re ...
