Large-scale variations of global groundwater from satellite gravimetry and hydrological models, 2002-2012

open access: yes, 2013
Groundwater storage is an important parameter in water resource management, land-surface processes and hydrological cycle. However, the traditional instruments are very difficult to monitor global groundwater storage variations due to high cost and ...

Catholyte‐Free Composite Cathodes Break the Energy Density Barrier of All‐Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
All‐solid‐state lithium batteries (ASSLBs) with conventional catholyte‐based composite cathodes have a theoretical energy density limit of approximately 400 Wh kg–1 and 900 Wh L–1. The design of catholyte‐free composite cathodes can break this barrier and improve the theoretical energy density up to 500 Wh kg–1 and 1000 Wh L–1. ABSTRACT The gravimetric

Signal separation in geodetic observations: satellite gravimetry

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
Signal separation is one of the key challenges in exploiting geodetic data for downstream applications, including the possible extraction of mantle convection-related signals from gravimetric (satellite gravity mission-derived) and geometric (global navigation satellite systems) data.

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

open access: yesChemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Experimental methods in chemical engineering: Cyclic voltammetry—CV

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...

Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity

open access: yesCleanMat, EarlyView.
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)

Dynamic Active Site Mechanism and Compositional Tuning in LaxSr1−xCoyFe1−yO3 (LSCF) Perovskites Toward Efficient Oxygen Evolution

open access: yesEcoEnergy, EarlyView.
A dynamic active site mechanism through cooperative metal–lattice oxygen interactions enables efficient oxygen evolution in LSCF perovskites without relying on oxygen vacancy formation, where the La/Sr ratio governs the intrinsic activity of LSCF and Co incorporation provides secondary enhancement, establishing a general composition‐guided paradigm for
