Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

Advanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Characterization of Immune Responses to RBD‐SD1 Nanoparticle Vaccines Derived From ACE2‐Capable HKU5‐CoV‐2, NeoCoV, and HKU5 Merbecoviruses

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles presenting HKU5, NeoCoV, and HKU5‐CoV‐2 RBD‐SD1 induced strong, cross‐reactive IgG responses in immunized mice. The surrogate virus neutralization test demonstrated strong activity in sera from homologous vaccination. ABSTRACT Recent discoveries of merbecoviruses such as HKU5, NeoCoV, and HKU5‐CoV‐2 that use angiotensin ...

Patch testing with hydroxyethyl-p-phenylenediamine sulfate - cross-reactivity with p-phenylenediamine

Contact Dermatitis, 2011
Adverse reactions to permanent hair dyes are frequent, and primarily result from sensitization to p-phenylenediamine (PPD).To investigate the degree of cross-reactivity to a chemically similar dye, hydroxyethyl-p-phenylenediamine sulfate (HPPS), and whether this might be a dyeing alternative for patients who are sensitive to PPD.HPPS was patch tested ...

Tetrabutylammonium tribromide: an effective green reagent for the one-pot reaction of 3-acetyl-2H-chromen-2-ones with o-phenylenediamines

ARKIVOC, 2018
An efficient and completely greener approach has been outlined for the reaction of 3-acetyl-2 H -chromen-2- ones with o-phenylenediamines using tetrabutylammonium tribromide (TBATB) to obtain 3-(quinoxalin-2-yl)- 2 H -chromen-2-ones in one-pot ...

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

MSI: A Mahalanobis-Based Molecular Similarity Index for High-Dimensional Embeddings. [PDF]

Mol Inform
MSI pairs continuous Mol2Vec embeddings with a covariance‐aware Mahalanobis metric (dM, θM) to overcome the ranking ties and bit‐density bias of Tanimoto fingerprints. Across five reference compounds, MSI resolves more distinct neighbors than ECFP4 + Tanimoto and its geometry tracks HOMO–LUMO gaps in QM9, despite no electronic training.
