Holt and Klee have recently shown that every (generic) LP orientation of the graph of a d-polytope satisfies a directed version of the d-connectivity property, i.e. there are d internally disjoint directed paths from a unique source to a unique sink. We in ...
The β-diketiminate class of ligands is renowned for the stabilization of coordinatively unsatd. main-group and transition metal complexes. Moreover, the application and scope of transition metal β-diketiminate complexes in the catalytic transformation of o ...
The catalytic activity of [Cp*OsBr2(PPh3)] in conjunction with Mg has been evaluated for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions. The Os complex enabled these reactions to be performed with similar efficiency as that of the a ...
[1] We present new measurements of Os-186/Os-188 and Os-187/Os-188 in 10 Os-rich platinum group element (PGE) alloys from placer deposits formed by the mechanical erosion of peridotite-bearing ophiolites in the Klamath and Siskiyou Mountains in northern Ca ...
The reaction of the anticancer compound (eta(6)-benzene)Ru(en)(OH2) (1) toward the nucleobases guanine, adenine, and cytosine is studied computationally using DFT/BP86 calculations. The aqua leaving group of such compounds is known to undergo ligand ...
The synthesis of [PPN][IrRu3(CO)13] and [PPN][IrOs3(CO)13] from the reaction of [PPN][Ir(CO)4] with M3(CO)12 (M = Ru or Os) is discussed. [PPN][IrRu3(CO)13] is a red-brown microcryst. powder, while [PPN][IrOs3(CO)13] is an orange-red microcryst. powder. Bo ...
We present a novel method for accurately splitting ionic samples at microchannel bifurcations. We leverage isotachophoresis (ITP) to focus and transport sample through a one-inlet, two-outlet microchannel bifurcation. We actively control the proportion of ...
A series of ruthenium, osmium and rhodium complexes utilizing pta, (1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane) and pta-Me+, its N-methyl derivative, have been synthesized. Their characterization by 1H and 31P NMR spectroscopy, ESI-MS and single crysta ...
We present first-principles mol. dynamics studies of the reductive C-S bond cleavage reaction in hexathioether complexes of the form [Re(9S3)2]m+ (with 9S3 = 1,4,7 trithiacyclononane and m = 1,2). Our calcns. show that electron transfer and bond dissocn. t ...
The potential, time, and concn. dependence of the potentiostatic electropolymn. of the thienyl-substituted transition metal complex [Os(bttpy)22+] onto platinum disk microelectrodes is reported, bttpy is 4'-(5-(2,2'-bithienyl))-2,2':6',2''-terpyridine. Oxi ...
