We develop electrochemical mean-field kinetic equations to simulate electrochemical cells. We start from a microscopic lattice-gas model with charged particles, and build mean-field kinetic equations following the lines of earlier work for neutral particles. We include the Poisson equation to account for the influence of the electric field on ion migration, and oxido-reduction processes on the ...

The title tetra-nuclear complex mol-ecule, [Sn(4)(C(7)H(7))(8)(C(2)H(2)ClO(2))(4)O(2)], has crystallographically imposed inversion symmetry. Each Sn atom has a distorted trigonal-bipyramidal geometry, with the equatorial plane formed by an oxido O atom and two C atoms of two benzyl anions. The configuration of the complex is stabilized by a pair of C-H⋯O hydrogen bonds. In the crystal, complex ...

In the title coordination polymer, {[Nd(C(5)H(2)N(3)O(6))(C(2)O(4))(H(2)O)(4)]·4H(2)O}(n), the oxalate dianions link adjacent nine-coordinate, tricapped trigonal-prismatic Nd(III) atoms into a chain running along the b axis. The 3,5-dinitropyridin-4-oxido N-oxide ligand is formally a zwitterionic anion; the anion binds to the metal atom through the N-oxide O atom. The chains are connected into ...

Fuzhuan brick tea, a kind of dark tea consumed mainly in the border regions of Southwestern and Northwestern China since the 1860s, is produced from the leaves of Camellia sinensis var. sinensis by microbial fermentation. From this special fermented tea, a new norisoprenoid, 3R,9R-oxido-5-megastigmene, was isolated, together with α-linolenic acid, strictin, isovitexin, astragalin, (+)-catechin,...

Heat generation is a very conspicuous phenomenon in large scale bioreactors and could in principle quite easily be measured by the temperature increase of the cooling water. Taking yeast cultures growing on a mixed oxido-reductive metabolism for various reasons as an example, this paper demonstrates how heat dissipation measurements may be used in combination with one other on-line measurement ...

Non-enveloped viruses enclose their genome in capsids built of repetitive polypeptides interlinked with cementing proteins, divalent cations or disulphides. Interactions are broken in a stepwise manner during entry into cells leading to genome uncoating. Receptor or proteases induce conformational changes in case of rhinovirus, poliovirus or adenovirus, and thereby provide direct uncoating cues...

In the title compound, [Dy(C(5)H(2.5)N(2)O(4))(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Dy(III) ion is located on a twofold rotation axis and is coordinated in a square-anti-prismatic geometry by two chelating 1,10-phenanthroline mol-ecules as well as two 4-oxido-2-oxo-2,3-di-hydro-pyrimidin-1-ium-5-carboxyl-ato(1.5-) anions. N-H⋯O and O-H⋯O hydrogen bonds help to stabilize the crystal structure. The ...

Hepatitis C virus (HCV) NS3-NS4A protease is an attractive target for anti-HCV agents because of its important role in replication. An optimized fluorescence resonance energy transfer (FRET) substrate for NS3-NS4A protease, based on the sequence of the NS5A-5B cleavage site, was designed and synthesized. High-throughput screening of in-house compound libraries was performed using a FRET substra...
