The stability and lifetime of lithium-ion batteries hinges on deciphering the reactive processes that occur where the cathode meets the electrolyte. During cycling, electrolyte components oxidise at the cathode-electrolyte interface and form a thin, reactive interphase. This layer is commonly known as the solid electrolyte interphase (SEI), or more specifically as the cathode-electrolyte interphase (CEI) when formed on cathodes. Although the SEI is crucial for stabilising the cathode-electrol
This study rigorously investigated the effect of charge-enhanced dry impregnation (CEDI) method on the physicochemical properties and catalytic performance of a ceria-supported nickel-based catalyst. The primary objective of the CEDI method was to augment the electrostatic adsorption of the nickel precursor onto the ceria support surface during the dry impregnation (DI) process. For a comprehensive comparative assessment, two distinct catalyst samples were synthesised: 10Ni/CeO2-CE
Why do some of the most promising next-generation batteries fail—and how can we stop it? A new peer-reviewed study led by Imperial College London answers that by watching the failure process unfold as the battery operates. Using simultaneous dual-polarity secondary-ion mass spectrometry (SIMS) alongside controlled electrochemical cycling, the team directly observed where, when, and why degradation starts inside solid-state sodium-ion batteries.
As semiconductor devices shrink to meet the demands of advanced electronics, the precision of material removal during fabrication becomes increasingly important. Processes like ion beam etching must stop precisely at targeted etch depths to preserve layer integrity and device function. In multi-layered device architectures, even minor deviations in etch depth can compromise performance or yield. Achieving consistent, accurate layer removal is therefore a core objective of semiconductor etchin

Electrochemical fuel cells are a transformative innovation in sustainable energy, offering the potential to replace combustion engines with cleaner, more efficient systems. Among the various fuels explored for these systems, hydrogen (H2) has become the focus of research. This is thanks to its high energy density and environmental benefits. But while
Biogas production has evolved from a niche practice into a pivotal part of renewable energy, converting organic waste into a clean energy source. Wastewater treatment plants, food waste facilities, and landfill gas recovery systems utilise anaerobic digesters to break down organic matter. This digestion process produces biogas—a mixture of methane and carbon dioxide. Capturing this energy, similar to natural gas, powers operations and reduces reliance on fossil fuels, while also mitigat
