Near-IR molar absorption coefficient for the OH-stretching mode of cis-9-octadecenoic acid and dissociation of the acid dimers in the pure liquid state

Makio Iwahashi、Masao Suzuki、Miros aw A. Czarnecki 等 5 位作者1995-01-01Journal of the Chemical Society Faraday Transactions

The molar absorption coefficient, εOH, at 1445 nm for the stretching mode of the unbonded OH in the carboxy group of cis-9-octadecenoic acid has been successfully determined by examination and correlation of both the absorbance at 1445 nm for a dilute CCl4 solution of the acid and the degree of dissociation, αo, of t…

Analytic FITS for partial photoionization cross sections.

D. A. Verner、D. G. Yakovlev1995-01-01Data Archiving and Networked Services (DANS)

We present a compact, uniform and complete set of analytic fits to the partial Hartree-Dirac-Slater photoionization cross sections for the ground state shells of all atoms and ions of elements from H to Zn (Z less-than-or-equal-to 30). Comparison with experiment and theory demonstrates generally high accuracy of the f…

Layered Polyaniline Composites with Cation‐Exchanging Properties for Positive Electrodes of Rechargeable Lithium Batteries

Masayuki Morita、Seijiro Miyazaki、Masashi Ishikawa 等 7 位作者1995-01-01Journal of The Electrochemical Society

Layered polyaniline/polyaniline‐polyanion composite films (PAn‐X/PAn‐PA) were synthesized by electrochemical oxidation of aniline in aqueous acid solutions ( , ) followed by polymerization in poly(styrene‐4‐sulfonic acid) (PSSH) solutions. The films consist of inner polyaniline (PAn) layers doped with smaller size ani…

Partial discharge plant-monitoring technology: present and future developments

I.J. Kemp1995-01-01IEE Proceedings - Science Measurement and Technology

The paper discusses the role of partial discharge measurement in the conditioning monitoring of power plant. Following a discussion of recent developments in partial discharge detection and measurement technologies, the problems and challenges for the future in the different technologies are analysed and discussed. Fo…

The Measurement of the Nematic Order Parameter by X-ray Scattering Reconsidered

Patrick Davidson、D. Petermann、A. M. Levelut1995-01-01Journal de Physique II

This paper reviews and extends the procedure used to measure the nematic order parameter by X-ray scattering. We show that the well-known integral equation derived by Leadbetter and coworkers, relating the scattered intensity I(θ) to the orientational distribution function f(β), can be analytically simplified both in…

Collagen microparticles: Preparation and properties

B. Rössler、J. Kreuter、Dieter Scherer1995-01-01Journal of Microencapsulation

Collagen microparticles (CMPs) of diameters ranging from about 3 to 40 microns were prepared by the method of emulsifying and cross-linking native collagen. The particle size was mainly controlled by the molecular weight of the collagen used: an increase in denaturation of the collagen resulted in smaller particle siz…

First-Principles Study of Carbon Nanotube Solid-State Packings

Jean‐Christophe Charlier、Xavier Gonze、J.-P. Michenaud1995-01-01Europhysics Letters (EPL)

In the framework of the density functional theory, we study the energetics and geometry of three-dimensional solids made of single-shell carbon nanotubes. Amongst the investigated forms, a hexagonal packing with an interdistance of 3.14 Å between the tubes is found to be the most stable. We find that the matching of a…

Thermodynamic investigation of the effect of octanol–water mutual miscibility on the partitioning and solubility of some guanine derivatives

Albin Kristl、Gorazd Vesnaver1995-01-01Journal of the Chemical Society Faraday Transactions

The effects of mutual saturation of octanol and water on solute partitioning and solubility have been examined. The partition coefficients and solubilities in octanol, water and mutually saturated octanol–water phases were determined for eight antivirus guanine derivatives. Using the solubility data, enthalpies of fus…

Interpretation of partial discharges at dc voltages

U. Fromm1995-01-01IEEE Transactions on Dielectrics and Electrical Insulation

The aim of this paper is to give an overview on partial discharges at dc voltage. A model is presented which describes the stochastic discharge process. The model is experimentally verified for internal discharges and for corona in air. In addition, the classification of discharge patterns is discussed. The 3-dimensio…
