Bounding and approximating parabolas for the spectrum of Heisenberg spin systems

, 2001
We prove that for a wide class of quantum spin systems with isotropic Heisenberg coupling the energy eigenvalues which belong to a total spin quantum number S have upper and lower bounds depending at most quadratically on S.

More Than a Buffer in Biochemistry: Tris as an Architect and Gatekeeper of Metal–Oxo Assembly

Angewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.
Tris(hydroxymethyl)aminomethane, depicted as an octopus, acts as an alkoxy ligand, chelator, and structure‐directing buffer that programs polyoxometalate's speciation, nucleation, and heterometal insertion in aqueous solution. ABSTRACT Polyoxometalates (POMs, molecular metal–oxo clusters) are typically studied and applied in aqueous media, where ...

Synthesis and Antibacterial Activity of Polyoxometalates with Different Structures

Bioinorganic Chemistry and Applications, 2018
A new inorganic-organic hybrid compound, [{Cu(phen)2}2(H4W12O40)], was synthesized, and its crystal structure was determined. The Keggin anion H4W12O404− was grafted with two coordination units {Cu(phen)2}, forming an electrically neutral molecule.

Theoretical and Experimental Investigations of Acetal Formation During the Oxidation of Xylose to Formic Acid Catalysed by H5PV2Mo10O40 in Methanolic‐Aqueous Solution [PDF]

ChemSusChem
The substrate‐solvent interactions play a major role in the modified OxFA process. Herein, the formation and stability of several reaction intermediates via acetalization depending on solvent composition and reaction conditions is investigated. The BioValCat (Enhanced Biomass Valorization by Engineering of Polyoxometalate Catalysts) project aims at ...

Polyoxometalates (POMs)

Polyoxometalates (POMs) represent a class of nanomaterials, which hold enormous promise for a range of energy-related applications. Their promise is owing to their "special"structure that gives POMs a truly unique ability to control redox reactions in energy conversion and storage. One such amazing capability is their large number of redox active sites

Monodisperse Manganese‐Vanadium‐Oxo Clusters with Extraordinary Lithium Storage

Advanced Science
Although possessing well‐defined nanostructures and excellent multi‐electron redox properties, polyoxometalate clusters have poor intrinsic electrical conductivity and are prone to aggregation due to large surface energy, which makes them difficult to be
