This research investigated spatial-temporal variation in benthic bacterial community structure, rates of denitrification and dissimilatory nitrate reduction to ammonium (DNRA) processes and abundances of corresponding genes and transcripts at three sites-the estuary-head, mid-estuary and the estuary mouth (EM) along the nitrate gradient of the Colne estuary over an annual cycle. Denitrification...

The itle compound, [Ca(C(6)H(3)ClNO(2))(2)(H(2)O)(2)](n), contains polymeric chains extending along [100] that are generated by inversion centres. The Ca(2+) ions are bridged by 2-chloronicotinate groups and exhibit an eight-coordination by six carboxylate O atoms of four different 2-chloronicotinate ligands and two O atoms of water molecules. In the crystal structure, inter-molecular O-H⋯O, O-...

Abstract Activity‐based protein profiling (ABPP) as a proteomic tool allows measuring the activity of enzyme classes or distinct proteins in their cellular context, annotating function uncharacterized proteins, and investigating target profile small molecule inhibitors. While hydrolases other classes, which exhibit characteristic nucleophilic residue, can be addressed by electrophilic activity‐...

A manganese succinate having a layer structure in which the layers are pillared by the isonicotinate spacers in a 3D architecture exhibits long-range ferrimagnetic order below 5.0 K, with the ferrimagnetism arising, for topological reasons, from the nature of the carboxylate binding modes. The compound is the first structurally authenticated example of a 3D ferrimagnet, featuring a homometallic...

The carboxyl-ate dianion in the title compound, [Pb(C(14)H(8)O(5))(C(19)H(12)N(4)O)(2)]·2H(2)O, uses one carboxyl-ate group to O,O'-chelate a bis-[4-(1H-1,3,7,8-tetra-azacyclo-penta-[l]phen-anthren-2-yl)phenol]-chelated Pb(II) atom and uses its other carboxyl-ate group to bind to another Pb(II) atom in an irregular monodentate manner. The Pb(II) atom exists in an undefined seven-coordinate geom...

Sequential palladium-catalysed direct (het)arylation of oxazole-4-carboxylates is achieved to give rapid access to DPO and POPOP (di)carboxylate-analogs. Three novel DPO- and POPOP-type sensors with unusual Stokes shifts and high quantum yields are discovered.
