Polarized light induces a preferred orientation of azobenzene groups through photochemical trans-cis-trans processes. Stronger orientation tendencies exist if the azo-containing polymers are crystalline or liquid crystalline and the cooperative reorientation of nonactive mesogens of similar shape has been demonstrated…
The dynamics of the molecular glass-forming liquid orthoterphenyl above the glass-transition temperature was studied combining several experimental techniques: depolarized Raman, depolarized Rayleigh-Brillouin light scattering, and photon correlation spectroscopy in the temperature range from 250 to 440 K. The combine…
Using the replica method, we derive the thermodynamic relations for a fluid in equilibrium with a quenched porous matrix. In particular, the appropriate Gibbs–Duhem equation is obtained as well as the equivalence between grand canonical and canonical ensembles. The exact compressiblity and virial equations are derived…

High‐resolution electron microscopy and nano‐beam analytical electron microscopy have been used to characterize both the intergranular silicate film thickness and its local composition in a series of high‐purity Si 3 N 4 ceramics doped with 0–450 at. ppm Ca. Calcium was detected at both two‐grain junctions and triple…

In the present study, the rf plasma chemical vapor deposition technique is applied to directly deposit a diamond-like carbon (DLC) film onto a zinc sulfide (ZnS) substrate with excellent adhesion. Great attention is paid to the investigation of the correlation between the deposition process parameters and the structur…
This paper describes detection and diagnostic techniques for partial discharges in gas insulated substations (GIS). Partial-discharge current waveforms of SF/sub 6/ gas and external noise characteristics of actual substations were investigated, and a measuring system having sensors in GIS and employing frequency range…
The XPS spectrum of the boron suboxide, B6O, is reported. The spectra were obtained on a powder sample that was prepared and characterized at the Diamond Technology Center, Norton Company. It was characterized with x-ray diffraction and was prepared by established methods. The B 1s peak is split into two components of…
Plutonium recycling in light water reactors (LWRs) has progressively become a fact. Over 200 t of mixedoxide (MOX) fuel have been produced in the COGEMA and BELGONUCLÉAIRE plants in the last 7 yr. Fuel loaded in European reactors—mainly MIMAS fuel—is presenting satisfactory in-core behavior and performance.Fuel fabric…

In this study, the surface composition of a fresh, commercial, alumina Claus catalyst (Alcoa S-100) was examined by x-ray photoelectron spectroscopy (XPS). This article presents the main XPS core lines and the valence band spectra obtained for the Claus catalyst. The electronic record includes the Al 2p, Al 2s, O 1s,…
XPS data have been obtained from a pressed AgO powder sample obtained from AESAR. Obtaining high-quality XPS data from a single oxide state is difficult because multiple oxide states, hydroxides, and other contaminants are usually present. The AgO sample was annealed in vacuum at 100°C for 30 min to reduce the amounts…
A detailed time domain model for the eddy current losses in the windings of a transformer is presented. The basic elements for the derivation of the model are the turns which may be combined into sections. The model is expressed as an R-matrix. Its diagonal elements were fitted using a series Foster circuit while for…
A new electrochemical method was developed to investigate crevice corrosion and its inhibitors. A wire beam electrode was used to allow electrochemical parameters to be measured directly from the crevice area. As an example, oil stain was investigated using this method.
