Abstract This paper presents the results of an experimental study of the miscibility gap between trioctahedral and dioctahedral micas in the system K 2 O Li 2 O-MgO-FeO-Al 2 O 3 -SiO 2 -H 2 O-HF at 600°C under 2 kbar P H2O . The existence of this miscibility gap is known from previous experimental studies. The gap is…

In this paper we wish to show that metal impregnated conducting polymers can be useful as the active material in microelectrochemical devices that respond to certain chemical changes in aqueous solution. We report here the impregnation of poly(3-methylthiophene) with metallic Pt in order to make the conducting polymer…

Freely suspended liquid-crystal films of the smectic-I phase of HOBACPC [R(-) hexyloxybenzylidene p'-amino-2-chloropropyl cinnamate] display distinctive stripe and droplet textures. We derive these patterns from a Landau expansion of the free energy using a vector order parameter. Strong pinning boundary conditions le…

Abstract Differential scanning calorimetry (DSC) and the density gradient technique (DGT) were used to determine, both isothermally and dynamically, the crystallization kinetics of polyetheretherketone (PEEK). The data were analyzed by a model utilizing, for the first time, two crystal nucleation and growth processes…

The nature of passive films formed on 304 stainless steel at +0.25V ( vs. SCE) in deaerated solutions of and has been determined by RHEED and variable angle XPS. Evidence is given of and Cl − incorporation into the outer Fe‐rich regions of the passive film. In addition to Cr 3+ species which make up the inner layer of…

The procedure of whole-powder-pattern fitting without reference to a structural model, first proposed by Pawley for use with neutron powder data [J. Appl. Cryst. (1981). 14, 357–361], was extended as a tool for analyzing X-ray whole-powder data. X-ray data for α-SiO2, α-Al2O3 and CaCO3 used as test samples were first…

Time- and frequency-dependent measurements of optical phase conjugation in gold colloids are reported. It is shown that the nonlinear response is fast on a 5-psec time scale and can be assigned to the electrons of the small metal spheres. The frequency-dependent measurements were performed in the neighborhood of the s…

We review work on In2O3:Sn films prepared by reactive e-beam evaporation of In2O3 with up to 9 mol % SnO2 onto heated glass. These films have excellent spectrally selective properties when the deposition rate is ∼0.2 nm/s, the substrate temperature is ≳150 °C, and the oxygen pressure is ∼5×10−4 Torr. Optimized coating…

The relation between two well known charge-density-wave (CDW) transport phenomena, namely the apparent increase in the threshold field E T for continuous Frohlich conduction in short specimens, and the memory effect seen when the direction of current flow is reversed, is investigated in experiments on NbSe 3 at temper…

A model in which photoexcited electrons in small metal particles are scattered elastically from the boundaries and travel inelastically within is included in a free-electron theory which successfully explains the enhanced photoelectric quantum yield of these systems relative to macroscopic metal surfaces.

The energy of an electron-hole pair in laser-excited semiconductor microcrystallites is computed with plasma screening and dielectric polarization taken into account. A strong excitation-induced blue shift of the absorption is predicted which causes a large optical nonlinearity for crystallite sizes exceeding the bulk…

The conformation of the glycine-rich loop of adenylate kinase is described in detail. It forms a giant anion hole for a sulfate ion, which presumably mimicks a nucleotide phosphoryl group. This loop had been called flexible, because at pH values of 6 or below it is displaced in the crystal. In the region of this loop…

Abstract Hindered amines and their derived oxidation products, the hindered nitroxyls and hydroxylamines are processing stabilizers and photoantioxidants for poly(vinyl chloride). The evidence suggests that oxidation of the amines occurs very rapidly and completely during mechanooxidation and that the resulting redox…

Abstract The swelling behavior of perfluorinated ionomer membranes in various solvents were studied. It was found that the sample pretreatments and the type of the functional group have a strong effect on the swelling properties of these membranes. The swelling of sulfonate membrane is higher than that of the carboxyl…
