Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

Advanced Science, EarlyView.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

Architecture‐Engineered Semi‐Crystalline Microporous Polymer Membranes for Precise Molecular Separation

Advanced Science, EarlyView.
Guided by a Random Forest model, a π–π‐driven ordered stacking strategy deploys functionally distinct substructures to restrict chain segment motion and increase free volume, while preserving the intermolecular interactions that maintain structural integrity.

Donor–Acceptor Covalent Organic Framework Enables Ambipolar Charge Storage in Aluminum‐Ion Energy Storage

Advanced Energy Materials, EarlyView.
A donor–acceptor covalent organic framework is designed as an ambipolar cathode for aluminum‐ion energy storage. The crystalline, microporous architecture enables intrinsic charge transport without conductive additives. Multi‐electron redox activity at donor and acceptor sites supports high capacity, excellent stability, and efficient reversible ...

The photosensitivity of EOM from diatom and its mediation of the photodegradation of p-phenylenediamines [PDF]

E3S Web of Conferences
Algal extracellular organic matter (EOM) can promote the photodegradation of p- phenylenediamines (PPDs), yet its effects exhibit highly compound-specific.

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 ...

Catalyst-free synthesis of substituted benzimidazoles and benzothiazoles in a sustainable solvent

Tetrahedron Green Chem
A catalyst-free synthesis of various 2-alkyl or aryl-substituted benzothiazoles and benzimidazoles has been developed at room temperature by simply combining alkyl or arylaldehydes with ortho-phenylenediamines and 2-aminothiophenols, respectively.

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.
