New complexes and adducts of xanthate the general formula [M(cyclopentyl xant.)2] xant.)2.nL] Where M= Mn(ΙΙ) Fe(ΙΙ), Co(ΙΙ), Ni(ΙΙ), Cu(ΙΙ) Zn(ΙΙ), (cyclopentyl xant.)2=[Cyclopentyl ligand], n=2 L= Pyridine, 3-acetyl pyridine & Quinoline n=1, ethylenediamine, (1,10)-phenanthroline, prepared has been evaluated based on their magnetic, electrical, physical characteristics. And spectral metho...

Encapsulation makes the difference!. A β-cyclodextrin-based diphosphane ligand with metal confining properties is key in stabilization of heteroleptic Cu(I) complexes. In their Research Article (e202214638), Nicola Armaroli, Béatrice Delavaux-Nicot, Jean-François Nierengarten, Dominique Armspach et al. show how encapsulation metal-bound diimine moiety cyclodextrin cavity influences electronic p...

We present an advanced algorithm for an extraction tool to compute inductances of interconnect structures. As already pointed out [Proc. Third Int. Conf. Modeling Simul. Microsyst. (2000) 416] the pursued energy concept leads to a 6-fold integral which can also be evaluated by use of the Monte Carlo method. A classical implementation of the Monte Carlo method, where the whole geometry has to be...

In the title compound, a new macrocyclic metal complex, [Ag(NO(3))(C(21)H(15)N(3)O(4))], all non-H atoms are in a close-to-planar geometry (except for the nitrate anion), with a maximum out-of-plane deviation of 0.327 (6) Å for a pyridine C atom. The dihedral angle between the least-squares plane through the [3,3'-dihy-droxy-3,3'-bis-(pyridin-3-yl)-1,1'-(pyridine-2,6-di-yl)dipropan-1-one]silver...

this research work is devoted to the development of a mathematical model for the simulation of the flow of polymeric melts through the die region of extruders. a set of governing equations are solved using finite element method. standard galerkin technique is used in conjunction with the mixed scheme to solve the flow equation. due to the non-linear nature of global equations, the picard iterat...

Nickel(II) complexes have attracted much attention as a new generation of olefin catalysts since the α-diiminonickel complex was discovered as a highly efficient procatalyst for ethylene polymerization. A series of novel 4-arylimino-1,2,3-trihydroacridylnickel(II) dihalide complexes was synthesized in a one-pot reaction of 2,3-dihydroacridine-4-one and different anilines with nickel(II) chlorid...

This paper presents a new inhomogeneous solid modeling paradigm for engineering design. The proposed paradigm can represent, model, and render multi-dimensional, physical attributes across any volumetric objects of complicated geometry and topology. A modeled object is formulated with a trivariate simplex spline defined over a tetrahedral decomposition of its 3D domain. Heterogeneous material a...

A surface is often approximated by a network of triangular facets. In the absence of a precise mathematical description of the underlying surface all information about surface properties such as smoothness and curvature must be inferred from the triangulation itself. Enrichment and coarsening of the surface geometry, for example, can only be carried out if singular features, where C continity i...

Six new 1-benzoyl-3-phenylthiourea and 1-benzoyl-3-(2-methylphenyl)thiourea complexes of mercury(II) were obtained in the reactions of the ligands with HgX2 in methanol (X = Cl, Br, I). Their structures, determined by single-crystal X-ray diffraction analysis, exhibit different stoichiometries and molecular organization. Coordination centers adopt more or less distorted tetrahedral geometry (fi...
