Concentrated water-in-salt electrolytes (WiSEs) are used in aqueous batteries and to control electrochemical reactions for fuel production. The hydrogen evolution reaction is a parasitic at the negative electrode that limits cell voltage WiSE leads self-discharge, affects selectivity electrosynthesis. Mitigating modulating these processes hampered by limited fundamental understanding of HER kinetics WiSEs. Here, we quantitatively assess how thermodynamics, kinetics, interface layers apparent...

A low-pressure Carbon Filter Process (patent pending) is proposed to capture carbon dioxide (CO2) from flue gas. This filter filled with a low-cost carbonaceous sorbent, such as activated or charcoal, which has high affinity (and, hence, capacity) CO2 but not nitrogen (N2). This, in turn, leads CO2/N2 selectivity, especially at low pressures. The this work can recover least 90% of flue-gas 90%+ purity fraction the cost normally associated conventional amine absorption process. requires...

Cs3Cu2I5 nanocrystals (NCs) are considered to be promising materials due their high photoluminescence efficiency and X-ray hardness. However, the present strategy depends on tedious fabrication with excessive chemical waste. The evasive iodide ion dissociation, inadaptable ligand system, low stability, relatively light yield severely impede applications. Herein, we develop an in situ for a flexible large-area Tl-doped NC-polymer composite scintillation film (∼48800 photons/MeV) improved...

Precise delineation of hepatic lesions from multi-phase MRI scans is paramount for the prompt diagnosis and treatment liver conditions. Conventional approaches typically emphasize either global or local features, often disregarding spatial interdependencies across modalities difficulties arising ambiguous tumor margins. To address these deficiencies, we propose AMHMF-Net, an advanced adaptive modality-channel-search Hadamard multimodal fusion network. This architecture leverages a dual...
