Resistance of Arbitrary Angle Corner
The field modelling becomes simpler if strong field nonuniformities are solved theoretically. The early-obtained formulas for 2-D "corner" permeances, (capacitances or resistances) pertain to right angle configurations. In this paper, using a conformal mapping and analytical approximations, the field in the vicinity of arbitrary angle corner is studied and the corner resistance determined. Obtained results can be applied to a large range of electromagnetic

Field modeling becomes simpler if strong field nonuniformities are solved theoretically. The early obtained formulas for 2-D “corner” and “constriction” permeances pertain to right angle configurations. In this paper, using a conformal mapping, the field in the vicinity of arbitrary angle vertex is studied and the fringing permeance determined. The results are applied to permeance evaluation of lunate cross section grooves from the rotors

Poised to understand the influence of O- and S-heteroatoms on the chemical reactivity of dicarboxylic acids toward Pb(II), leading to crystalline metal–organic hybrid materials with distinct lattice architecture, dimensionality, and spectroscopic properties, the synthesis and physicochemical properties of binary/ternary Pb(II)–(O,S)-dicarboxylic acid–(phenanthroline) systems was investigated in aqueous media. pH-specific hydrothermal reactions

Chromium is widespread in the environment and is used in ample industrial applications in abiotic and biological systems. Its ability to influence biological processes through interactions with biomolecules underscores its positive role as well as its toxic manifestations in higher organisms. In an attempt to understand its (bio)chemistry, research efforts were undertaken to explore the aqueous chemistry of Cr(III) with the low molecular mass physiological

Hydrothermal pH-specific reactivity in the binary/ternary systems of Pb(II) with the carboxylic acids N-hydroxyethyliminodiacetic acid (Heida), 1,3-diamino-2-hydroxypropane-N,N,N',N'-tetraacetic acid (Dpot), and 1,10-phenanthroline (Phen) afforded the new well-defined crystalline compounds Pb(Heida)]n·nH2O(1), [Pb(Phen)(Heida)]·4H2O(2), and [Pb3(NO3)(Dpot)]n(3). All compounds were characterized by elemental analysis, FT-IR, solution or/and solid-state

Synthetic efforts linked to the design of defined lattice dimensionality and architecture materials in the binary/ternary systems of Cu(II) with butylene diamine tetra(methylene phosphonic acid) (H8BDTMP) and heterocyclic organic chelators (pyridine and 1,10-phenanthroline) led to the isolation of new copper organophosphonate compounds, namely, Na6[Cu2(BDTMP)(H2O)4]· Cu2(BDTMP)H2O)4]0.5·26H2O (1), [Cu2(H4BDTMP)(py)4 ] ·2H2O (2) , and [Cu2(H4BDTMP)-(phen)2]n·6.6nH2O·1.5nMeOH
