Groundwater Representation in Water Resource Planning: The Spatial and Temporal Sensitivity of Groundwater Supplies in England

Water and Environment Journal, EarlyView.
ABSTRACT Groundwater makes an important contribution to public water supplies, yet the dynamics of groundwater availability are often simplified in large‐scale water resource assessments. This study addresses that challenge on a national scale in England by integrating an empirically based groundwater supply model with a national‐scale water resource ...

Groundwater Variability Is Strongly Linked to Soil Temperature Across Global Aquifers

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Groundwater plays a critical role in land‐atmosphere interactions by regulating soil moisture and surface energy fluxes, yet its contribution to land‐surface processes and heat extremes remains poorly quantified globally. Here, we combine observation‐based aquifer records with gridded groundwater table depth (GWD) model outputs (2000–2015) to ...

The Role of Charge Transfer and Linker States in the Magnetoluminescence of a Diradical With Two Spatially Proximate Triarylmethyl Units

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
Magnetoluminescent (ML) diradicals exhibit field‐dependent emission due to magnetic field‐dependent spin state populations and spin‐dependent emission properties. In this work, quantum chemical calculations applied to the first reported ML diradical provide evidence of the different deactivation pathways of the excited singlet and triplet states and ...

A Portable and Dual‐Button Microneedle Device Enables Intelligent Multimodal Laser Sensing

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A portable and dual‐button microneedle device enables rapid interstitial fluid sampling. Coupled with multimodal laser sensing and AI‐assisted data processing, the platform enables simultaneous molecular and elemental analysis for minimally invasive and multiplexed health assessment toward point‐of‐care diagnostics.

Counterion Effects on the Properties and Reactivity of Charged Photoredox Catalysts

ChemPhotoChem, Volume 10, Issue 8, August 2026.
The choice of a counterion for a charged photocatalyst has long been overlooked. In this review, we summarize recent reports on counterion effects in photocatalysis, providing readers with a comprehensive theoretical understanding and synthetic applications for the use of a carefully chosen counterion. Electrostatic interactions represent the strongest

Are Online Social Experiences Associated With General Interpersonal Problems? A Circumplex Assessment

Journal of Clinical Psychology, Volume 82, Issue 8, Page 1166-1176, August 2026.
ABSTRACT Objective Social media use can promote social connection but also often includes negative experiences, raising questions about its associations with broader interpersonal functioning. Methods This preregistered study used the interpersonal circumplex (IPC) to examine associations of self‐reported online social support and negativity, and ...

Azole‐Based Diarylbenzenes for Molecular Solar Thermal Energy Storage: A Computational Analysis

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
Diarylethenes containing aromatic π‐linkers have attracted research interest in recent years owing to their potential applications in molecular solar thermal (MOST) energy storage systems. In this work, we demonstrate that replacing the thienyl core of diarylbenzenes with an oxazole core and introducing lateral alkyl‐substituents on the oxazole core ...

Ultrafast Nonadiabatic Dynamics of Tetraphenyl‐substituted Nitrogen‐Based Heterocycles

Small Structures, Volume 7, Issue 8, August 2026.
Two molecules share four phenyl substituents but differ in their core (pyrazine vs. pyrrole), leading to very different emission behavior. One becomes highly emissive upon aggregation, while the other emits similarly in solution and solid states.
