Abstract Two dinuclear succinato‐bridged nickel(II) complexes [Ni(RR‐L)]2(μ‐SA)(ClO4)2 (1) and [Ni(SS‐L)]2(μ‐SA)(ClO4)2 (2) (L = 5, 5, 7, 12, 12, 14‐hexamethyl‐1, 4, 8, 11‐tetraazacyclotetradecane, SA = succinic acid) were synthesized and characterized by EA, Circular dichroism (CD), as well as IR and UV/Vis spectrosc…
How should one select the best detector for a particular measurement in energy dispersive X‐ray fluorescence (EDXRF)? How should one select the optimum system configuration, i.e. the best shaping time and beam current? Manufacturers provide a variety of specifications, such as energy resolution and maximum count rate,…
Das Geheimnis eines langen Lebens: Die vollständig deuterierte 13C-markierte Methoxygruppe (13CD3O) wird als neue funktionelle Gruppe mit langlebiger Hyperpolarisierung für die Entwicklung einer empfindlichen 13C-Kernresonanzsonde beschrieben. Die entsprechende Methode wurde für den Nachweis von hypochloriger Säure ge…
Benzoperylene derivatives with two angularly attached dicarboxylic imide rings, which were prepared by the Diels-Alder-reaction, exhibit strong fluorescence and their free peri positions allow either control of the UV/Vis spectra through their substituents or form anchor positions for the attachment of functional unit…
Polyethyleneimine ( PEI ) functionalized with hydrophobic toluoyl groups (T‐ PEI ) was used to control the viscosity of silicon carbide ( SiC ) nanoparticle aqueous suspensions. The effects of the toluoyl group ratio and molecular weight ( MW ) of the dispersant on the suspension viscosity were examined. For T‐ PEI s…
Effects of environmental dielectric materials on cross-polarized excitons of semiconducting carbon nanotubes are theoretically studied in an effective-mass scheme. When a nanotube is surrounded by a medium, the bright exciton, shifted to the high-energy side by depolarization effect, becomes weaker and disappears with…
The method for imaging of highly sensitive nanostructures unstable under electron beam irradiation is introduced. To reduce charge and thermally generated beam damage, highly conductive multilayered graphene or thin graphite layers were used as supports for nanostructures. Well-defined crystalline structure of graphit…
Abstract The dependence of the gallium trichloride saturated and unsaturated vapor pressures on temperature was studied by the static method using a quartz membrane zero‐manometer and taking into account the volume of its working chamber and substance mass. Conclusions about the presence of a distinguishable amount of…
The Middle Ordovician bathyurid trilobite Pseudoolenoides Hintze has been treated in only a small handful of papers andfew of its species have been adequately known. Here we revise all previously known species on the basis of new materialand illustrations, and describe four new species, three of which are formally nam…
Abstract The novel multi‐ligand coordination compound [Co(IMI)4(PA)](PA) (1) was synthesized by using imidazole (IMI) and picrate (PA) and characterized by elemental analysis and FT‐IR spectroscopy. The crystal structure was determined by X‐ray single crystal diffraction and the crystallographic data showed that the c…
Abstract Over the last few years, the use of work rolls for hot rolling of flat steel has been changed from clear chill rolls to indefinite chill, then high chrome steel and now high speed tool steel (HSS). HSS rolls are highly crack‐sensitive because of its high surface hardness. The crack propagation develops within…
Purpose Urethane Acrylate Oligomer with 100% solids was synthesised and characterised in order to study the application in electron beam curing with varying ratio of Trimethylol propane triacrylate (TMPTA). The purpose of this paper is to study effect of TMPTA addition on the crosslink density and different coating pr…
Two eucalyptus hybrids (EGC 39, EGC 241), resulting from crosses between Eucalyptus grandis and Eucalyptus camaldulensis, were investigated to see if they could produce kraft papermaking fibers with low lignin and adequate physical properties. The two hybrids were harvested at an age of 8 years along with 6-8 year old…
RecG is a DNA translocase that helps to maintain genomic integrity. Initial studies suggested a role in promoting recombination, a possibility consistent with synergism between recG and ruv null alleles and reinforced when the protein was shown to unwind Holliday junctions. In this article we describe novel suppressor…
Superfine cobaltous oxide nanoparticles (CoONPs) of ∼2.5 nm diameter were synthesized at high rate via discharge plasma operated in an aqueous solution of Co(II) acetate. Two potential routes are proposed for the CoONP formation: one is the plasma-induced electrolysis of the aqueous solution of Co(II) acetate, and the…
The measurements of Bartsch et al (1992 J. Phys. B: At. Mol. Opt. Phys. 25 1511) of the left–right spin asymmetry for elastic and inelastic scattering of polarized electrons from unpolarized indium atoms are compared with corresponding relativistic convergent close-coupling (RCCC) calculations over the full range of e…
We report a thin-film piezoelectric microelectromechanical systems (MEMS) transducer suitable for in vivo implantation as audio prosthesis and a method for fabricating it. The transducer consists of a layered stack of thin films comprising a MEMS membrane made of an isolating oxide interface; two platinum (Pt) layers…
Purpose The purpose of this paper is to propose a magnetic-geared motor with permanent magnets only on the high-speed rotor as a solution to the problems of magnetic gears. Magnetic gears have some advantages such as no mechanical loss and maintenance-free operation that are not observed in conventional mechanical gea…
This article describes a novel algorithm for the optimization of valence bond self-consistent field (VBSCF) wave function for a complete active space (CAS), so-called VBSCF(CAS). This was achieved by applying the strategies adopted in the optimization of CASSCF wave functions to VBSCF(CAS) wave functions, using an aux…
Abstract Magnetic support was prepared by precipitation from an alkaline solution of divalent and trivalent iron ions and subsequently was modified with 3‐aminopropyltriethoxysilane. FTIR analysis showed existence of a new Si–O–Fe bond in obtained particles. Scanning electronic microscopy images shows that the nanopar…
