The title compound, [Cu2(C17H17N4S)2Cl2], exhibits a dimeric structure related by a centre of symmetry. The monomers are linked to each other by the longest Cu-S apical distance observed to date among Cu(II) square-pyramidal complexes of N4-substituted thiosemicarbazones. Each Cu(II) atom deviates from the coordination square plane, which contains the pyridyl and imine N atoms, the thiolate S a...
Regioselective synthesis of novel N2- and N4-substituted 7-methylpyrazolo[4,5-e][1,2,4]thiadiazines.
The new compound 7-methylpyrazolo[4,5-e][1,2,4]thiadiazin-3(2H,4H)-one1,1-dioxide (5) was synthesized and its novel mono N2- or N4-substituted derivatives 6 and 7 were prepared by regioselective N-alkylation of 5 with different molar ratios of NaH and alkyl halides. Based on the regioselective alkylation conditions found a facile one-pot synthesis of N2,N4-disubstituted pyrazolo[4,5-e][1,2,4] t...
Supergravities are usually presented in a so-called 1.5 order formulation. Here we present a general scheme to derive pure 1 st order formulations of supergravities from the 1.5 order ones. The example of N4 = 1 supergravity will be rederived and new results for N4 = 2 and N11 = 1 will be presented. It seems that beyond four dimensions the auxiliary fields introduced to obtain first order formu...
A parallel algorithm for prefix computation reported recently on interconnection network called OTIS-Mesh Of Trees[4]. Using n4 processors, algorithm shown to run in 13log n + O(1) electronic moves and 2 optical moves for n4 data points. In this paper we present new and improved parallel algorithm for prefix on OTIS-Mesh of Trees. The algorithm requires 10log n + O(1) electronic steps + 1 optic...
Nanoscrolls (papyrus-like nanostructures) are very attractive structures for a variety of applications, owing to their tunable diameter and large accessible surface area. They have been successfully synthesized from different materials. In this work, we investigate, through fully atomistic molecular dynamics simulations, the dynamics of scroll formation for a series of graphene-like carbon nitr...
In this paper, we present efficient layouts for complete graphs and star graphs. We show that an N-node complete graph can be optimally laid out using LN2/4] tracks for a colinear layout, and can be laid out in N4/16 + o(N4) area for a 2D layout. We also show that an N-node star graph can be laid out in N2/16 + o(N2) area, which is smaller than any possible layout of a similar-size hypercube. T...
This report is on the electrical properties of all-amorphous junction field-effect transistors (JFETs) based n-type zinc oxynitride (ZnON) as a channel material and room-temperature deposited p-type ZnCo2O4 (ZCO) heterojunction gate. Devices with different thicknesses are thereby compared. Best devices 48 nm layer thickness achieve drain current on/off–ratios 105 low subthreshold swing 134 mV d...

N4-[N-(6-trifluoroacetylamidocaproyl)-2-aminoethyl]-5'-O-dimethoxy trityl -5-methyl-2'-deoxycytidine-3'-N,N-diisopropyl-methylphosphoramidite++ + has been synthesized. This N4-alkylamino deoxycytidine derivative has been incorporated into oligonucleotide probes during chemical DNA synthesis. Subsequent to deprotection and purification, fluorescent (fluorescein, Texas Red and rhodamine), chemilu...
A new family of Tetraazamacrocyclic Ru(II) complexes [RuCl2(L)] (where L = N4 donor macrocyclic ligands) have been synthesized by the reactions of [RuCl2(DMSO)4] with some of macrocyclic Schiff base ligands containing N4 donor groups. The complexes were characterized by elemental analysis, IR, H, C NMR, mass, electronic, molar conductance and magnetic susceptibility measurements. An octahedral ...
