An electron-rich zinc-modified zeolite Y material shows substantial activity for the decomposition of CO(2) to carbon with the release of O(2) at about 300 °C. It is elucidated that electrons delocalized in the vicinity of zinc cations in the zeolite material play an essential role in the decomposition reaction.

Prussian blue analogs (PBAs) are an important material class for aqueous electrochemical separations and energy storage owing to their ability reversibly intercalate monovalent cations. However, incorporating interstitial H2O molecules in the ab initio study of PBAs is technically challenging, though essential understanding interactions between water, cations, framework lattice that affect inte...

increasing urbanisation and industrialisation have led to a dramatic reduction in forest area, and now only culturally protected remnants of natural forests and some new plantations remain in most areas of the north of iran. to investigate the status of the chemical and physical characteristics of soil under these remnant forests and assess the possible impacts of reforestation on soil properti...

The mechanism by which bi-and trivalent cations affect human liver phosphatidatephosphohydrolase (PAP) activity was investigated. Bivalent cations up to 1 mM increased PAP activity whereas at higher concentrations the activity of the enzyme decreased. The stimulatory concentration for trivalent cations such as Al3+ and Cr3+, however, was much lower being 2 m M and 1 m M, respectively. All catio...

The vesicular nucleotide transporter (VNUT) is a secretory vesicle protein that is responsible for the vesicular storage and subsequent exocytosis of ATP (Sawada, K. et al., (2008) Proc. Natl. Acad. Sci. U.S.A. 105, 11720-11724). Since VNUT actively transports ATP in a membrane potential (Δψ)-dependent manner irrespective of divalent cations such as Mg or Ca, VNUT recognizes free ATP as a trans...

Porous and water-stable hybrid semiconductors as multifunctional materials display traits that are essential for demanding commercial applications. In their Research Article (e202218429), Ioannis Spanopoulos co-workers report a strategy generating porosity in metal halide by using molecular cages both structure-directing agents counter-cations. This gave rise to direct bandgap semiconductor wit...
