Hydrogen Bonding Network in Interlayer Spaces of a Partially Deuterated Layered α‐Sn (IV) Phosphate: A Solid‐State MAS NMR Study

Magnetic Resonance in Chemistry, EarlyView.
The solid‐state 1H and 2H NMR data collected for deuterated α‐Sn (HPO4)2 phosphate suggest the hydrogen bonding network, where the cavity water accepts one hydrogen bond from the P‐OH donor group and forms one hydrogen bond with the neighboring phosphate group, while the other water hydrogen is not involved in hydrogen bonding.

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

ChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.
