Five doped nanosized spinel ferrites were synthesized using the dicarboxylate and hydroxide coprecipitation method. XRD of samples confirmed increase in lattice parameters as compared to undoped samples. Decrease saturation magnetization coercive force are found these

In the title compound, {[Ho(4)(C(12)H(6)O(4))(6)(H(2)O)(5)]·1.75H(2)O}(n), which is isostructural with its Tb(3+)- and Eu(3+)-containing analogues, there are four crystallographically independent Ho(3+) centres, each exhibiting a highly distorted HoO(8) bicapped trigonal-prismatic coordination environment. Adjacent polyhedra are inter-connected via the carboxyl-ate groups and one μ(2)-bridging ...

K+ depolarization or addition of glutamate to a synaptoneurosome preparation triggers a rapid increase in size of polyribosomal aggregates isolated by centrifugation of lysate through 1 M sucrose. The profile of response to the glutamate analogues quisqualate, ibotenate, and 1-aminocyclopentane-1,3-dicarboxylate corresponds to that of metabotropic receptors. Glutamate stimulation is mimicked by...

We provide further insight into the photochemical control of viscoelasticity through the use of azobenzene sodium dicarboxylate for molecular switching. As a photoresponsive molecule, Sodium 3,3'-azobenzene dicarboxylate (3,3'-Azo2Na) was added to a solution of cetyltrimethylammonium bromide (CTAB)/sodium salicylate (NaSal), which is known for inducing the formation of wormlike micelles. This s...

The synthesis and physical properties of the ternary complex 3(2+), prepared by reaction of a naphthalene diimide dicarboxylate 2 with the binucleating dinickel(II) cavitand 1, are discussed. The complex 3(2+) is characterised by cyclic voltammetry which shows a wealth of metal-centred and diimide-based processes at -1.62, -1.04 and 0.15 V vs Fc/Fc+. Absorption and fluorescence spectroscopy of ...

N-Methyl-3-acylpyrroles were synthesized via a multicomponent reaction of dimethylacetylene dicarboxylate (DMAD), N-methylhydroxylamine and acylchlorides in the presence of KHCO(3). For comparison both conventional and microwave protocols were examined in this procedure. The reaction is clean and gives the products in good to excellent yields under conventional heating conditions at 40 degrees ...

The extent to and the mechanism by which fructose-1,6-bisphosphate (FDP) crosses cell membranes are unknown. We hypothesized that its transport is either via band 3 or a dicarboxylate transporter. The question was addressed in isolated Langendorff rat hearts perfused under normoxic conditions. Groups of hearts received the following metabolic substrates (in mM): 5 FDP; 5 FDP + either 5, 10, or ...

The electrical properties of metal-organic frameworks (MOF) have attracted attention for MOF as electronic materials. We report on/off switchable electronic conduction behavior with thermal responsiveness in intercalated MOF (iMOF) with layered structure, 2,6-naphthalene dicarboxylate dilithium, which was previously reported as a reversible Li-intercalation electrode material. The I-V response ...

We have found that the specific capacity of a Li-intercalated metal-organic framework (iMOF) electrode material, 2,6-naphthalene dicarboxylate dilithium, can be increased by narrowing the distance between naphthalene layers via ordering. The increase in specific capacity can be attributed to formation of more efficient electron and ion pathways in the framework.

The MM quadruple bond of configuration MM sigma2pi4delta2 is redox active and in many ways ideally suited for studies of mixed valency when two or more such centres are linked by a bridging ligand. In this account, the mechanism of electronic coupling is examined for complexes of the type [L3M2bridgeM2L3]0/+ where L, a pivalate; bridge, a dicarboxylate or related ligand and M, Mo or W. The repr...
