The reactions o f M n(CF3COO)2 (1) with N,N,N',N'-tetramethylethylenediamine (tmen), 2,2'-bipyridine (bipy) and triethanolamine (tea) yield three new mononuclear coordination compounds: rra«5-[Mn(tmen)2(CF3COO)2] (2), cw-[Mn(bipy)2(C F3COO)2] (3), and [Mn(tea)2](CF3COO)2 (4). The X-ray structures o f the compounds 2, 3, and 4 are described. The seven-coordination o f the manganese(II) ion in 4,...

Carbomer gel was prepared with 300mM D-sorbitol (Sigma-Aldrich, St. Louis, MO) and 10mM HEPES free acid (Sigma-Aldrich, St. Louis, MO) in heated distilled water. A gelling agent, carbomer 940 (Snowdrift Farm, Tucson, AZ), was added to the heated sorbitol solution under constant stirring, to reach a concentration of 0.3%, based on a weight percent. Once the carbomer was completely dissolved in t...

An artificial zinc porphyrin-myoglobin-based photo-chemical energy conversion system, consisting of ZnPP-Mb or ZnPE(1)-Mb as a photosensitizer, NADP(+) as an electron acceptor, and triethanolamine as an electron donor, has been constructed to mimic photosystem I. The photoirradiated product is able to reduce a single-electron acceptor protein cytochrome c, but cannot catalyze the two-electron r...

The use of conventional drugs for the treatment pain and inflammation has largely resulted in various side effects. These challenges have triggered search alternative therapy such as herbal medication that may serve a safe, effective, alternate approach to managing inflammation. Vitex negundo, potential lipophilic molecule, possesses limited solubility permeability. Emulgels are either water-in...

Ž . Ž Three-dimensional multistructure assemblies consisting of gold nanoparticles and a sulfur-containing ruthenium II tris 2,2-bi. pyridine derivative were fabricated on an ITO electrode by their alternate self-assembling. Absorption spectra of the assemblies showed immobilization of the gold surface and the ruthenium complex. Broadening and red shift of the plasmon band were observed by incr...

Ž . We report the first observation of residual dipolar couplings in magic-angle-spinning MAS and multiple quantum Ž . magic-angle-spinning MQMAS NMR spectra of half-integer quadrupolar nuclei. In particular, the fine spectral splittings observed in the B MAS spectrum of crystalline triethanolamine borate are attributed to the residual B–N dipolar coupling, which is not completely averaged by M...
