Carbon‐Modified SnS2/g‐C3N4 S‐Scheme Heterostructure with Enhanced Interfacial Charge Transfer for Efficient Photocatalytic Reduction of Cr(VI) and 4‐Nitrophenol

Small, EarlyView.
The S‐scheme of SnS2‐C/g‐C3N4 heterostructure enables Photocatalytic Cr(VI) and 4‐NP reduction. ABSTRACT Hexavalent chromium (Cr(VI)) and 4‐nitrophenol (4‐NP) are persistent and highly toxic water pollutants that require efficient treatment under mild conditions. In this work, L‐cysteine‐derived carbon‐modified SnS2 (SnS2‐C) was prepared hydrothermally

The Reaction of Creatine Kinase with 2-Chloromercuri-4-nitrophenol

Journal of Biological Chemistry, 1974
Abstract Creatine kinase from chicken breast muscle can be titrated stoichiometrically with 2 equivalents of 2-chloromercuri-4-nitrophenol, a chromophoric probe specific for thiols, without loss of enzymatic activity (Quiocho, F. A., and Thomson, J. W. (1973) Proc. Nat. Acad. Sci. U. S. A. 70, 2858–2862). The rate of reaction of mercurinitrophenol with

Investigations on the Luminescence Behavior of a Flavin Derivative Incorporated Into Al‐Based Metal–Organic Frameworks for the Sensing of Aromatic Nitro Compounds

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
For nitro group‐containing volatile compounds, a quenching effect was observed for DAMI@MOF, while the non‐nitro compounds chlorobenzene, toluene, and benzene yielded a fluorescence enhancement, rationalized by the relative energies of the derivative 8‐(dimethylamino)‐10‐methylisoalloxazine (DAMI) and analyte S1 states, with concomitant opposite ...

Facilitation and competition between Acacia species and phosphorus‐mobilising plants in severely phosphorus‐impoverished habitats

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants in fire‐prone severely phosphorus (P)‐impoverished environments exhibit diverse P‐acquisition strategies coordinated with root morphological traits. Fire transiently enhances plant‐available soil P, making efficient post‐fire P acquisition crucial for seedling ...
