General guidelines for corrosion testing of materials for marine applications: Literature review on sea water as test environment
This literature review is intended to give some general guidelines on corrosion testing of metals and alloys for marine applications, in particular with regard to the choice of the test environment. The general chemical properties of sea water are discussed and compared with those of coastal and/or polluted sea water,…
An assessment of the physical basis for the application of design criteria for dielectric structures
The use of design criteria for assessing the stresses to which composite dielectric structures are subjected implies careful and informed application. The convention required in the application of these criteria is examined in the light of the physical processes expected in an oil/cellulose transformer structure and r…
Dislocation loop punching in bubble arrays
High densities of inert gas bubbles can be produced in metals by ion implantation or nuclear transmutations. At low temperatures, these bubbles grow by repeated emission of prismatic dislocation loops. An analysis is presented for loop punching considering the effects of the stress fields between bubbles and the prese…
Accelerated Irradiation Growth of Zirconium Alloys
Sponge zirconium and Zr-2.5 wt% Nb, Zircaloy, or Excel alloys all exhibit accelerated irradiation growth compared with high-purity crystal-bar zirconium for irradiation temperatures between 550 to 710 K and fluences between 0.1 to 10 × 1025 n ∙ m-2 (E > 1 MeV). There is generally an incubation period or fluence…

Low-lying electronic states in µ-phenolato copper( II ) binuclear compounds with hydroxo, ethanolato, azido, and cyanato exogenous bridges: crystal structures, magnetic properties, and interpretations
Four novel µ-phenolato copper(II) binuclear complexes with exogenous bridges were synthesized, namely [Cu2L3(X)][CLO4]2, X = N3(1) or OCN (2) and [Cu2L4(X)][ClO4]2·H2O, X = C2H5O (3) or N3(4), L3 is the binucleating ligand 4-methyl-2,6-bis[N-(2-pyridylethyl)formimidoyl]phenolate and L4= 4-methyl-2,6-bis[N-(2-methylthi…
Switehing Impulse Strength of Air Insulation: Leader Inception Criterion
The paper introduces a general criterion for leader inception of phase-to-ground air insulation under positive critical switching impulses. The new leader inception criterion establishes the correspondence between continuous leader initiation in the vicinity of the highly stressed electrode and conditions prevailing l…
Structural and dynamic properties of a new type of discotic nematic compounds
Thermodynamic, structural and dynamical properties of a new type of discotic compounds, a hydrocarbon without any heteroatoms, displaying a nematic discotic phase have been investigated by means of X-ray diffraction, electro-optical relaxation, and calorimetric studies. Of particular interest are the strength of the f…
Structurally bound water and surface characterization of amorphous silica
Abstract
The novel mixed-valence, exchange-coupled, class III dimer [L 2 Fe 2 (µ-OH) 3 ] 2+ (L =N,N′,N″-trimethyl-1,4,7-triazacyclononane)
The reaction of Fe(CIO4)2·6H2O with N,N′,N,″-trimethyl-1,4,7-triazacyclononane (L) in methanol affords, in the presence of a small amount of oxygen, the deep blue binuclear complex [L2Fe2(µ-OH)3](CIO4)2·2MeOH·2H2O which was characterized by EXAFS, e.s.r., u.v.-visible and Mössbauer spectroscopy to be a mixed valence i…

Crystal Rotations Represented as Rodrigues Vectors
Rodrigues vectors are explored as a means of representing crystal orientation distributions. Relationships between the Rodrigues vectors and several more commonly utilized representations of rotations are presented. The restrictions which cubic material symmetry imposes on the Rodrigues space are examined and relation…
THE NUCLEATION OF MICROCELLULAR FOAMS IN SEMI CRYSTALLINE THERMOPLASTICS∗
The nucleation of microcellular foams in amorphous thermoplastics has been performed by supersaturation with gas at an elevated temperature. Pressure and temperature are then carefully reduced in the vicinity of the glass transition temperature of the material. The result is a foam structure with cells on the order of…
Control of charging in low‐voltage SEM
Abstract Charging of the specimen under electron beam irradiation is a common problem in scanning electron microscopy (SEM). It results in unstable imaging conditions and a loss in resolution due to defocus of the beam. In addition, it can cause permanent changes in some specimens from translocation of mobile ions und…

Starting of large motors-methods and economics
The authors evaluate the available starting methods for motors above 3000 HP, focusing on technical and economic aspects. The following starting schemes are discussed: direct online, reactor, autotransformer, capacitor, captive transformer, and frequency start. A review of the network conditions that favor a particula…
Ellipsometric studies of polyaniline growth and redox cycling
Ellipsometry has been used to characterise the growth of polyaniline films on platinum and gold electrodes by potential cycling. Analysis of the time evolution of the ellipsometric parameters allowed continuous monitoring of the growth process, and subsequent measurements of the changes in optical properties during ox…
Electrostriction of the cholesteric blue phases BPI and BPII in mixtures with positive dielectric anisotropy
The electrostriction of the cubic blue phases was investigated in the well known mixture CB15/E9. The results for BPI prove that a decrease of the lattice constant in the field direction with increasing field strength can occur in a system with positive dielectric anisotropy. In agreement with recent theoretical consi…
Morphological characteristics of the orthorhombic martensite in a shape memory Ti-Ni-Cu alloy.
Morphological characteristics of the orthorhombic martensite in a Ti–Ni–Cu shape memory alloy have been investigated and the following have been found:(1) In the cubic (B2) to orthorhombic transformation of the Ti–Ni–Cu alloy, no lattice invariant shear is needed. This is due to the fact that one of the principal dist…
