Chemiluminescence of Anodized and Etched Silicon: Evidence for a Luminescent Siloxene-Like Layer on Porous Silicon
Treatment of anodized or chemically etched silicon ("porous silicon") with dilute nitric acid or persulfate solution results in weak chemiluminescence in the visible region. Concentrated nitric acid reacts violently with porous Si produced by anodization with a bright flash of light. The fact that similar reactions oc…
Measurement of complex refractive index of soda-lime glass at 60 GHz by vector-network-analyser-based scatterometer
The complex refractive index at 60 GHz of soda-lime glass, which is commonly used as window glass, has been measured by means of a free-space reflection method using a vector-network-analyser-based scatterometer. The complex refractive index was estimated to be 2.61 – 0.0318j, which is consistent with previously-repor…
Room temperature cw fibre laser at 3.5 μm in Er 3+ -doped ZBLAN glass
The first fibre laser operating above 3 μm at room temperature is reported. An Er3+-doped ZBLAN fibre pumped at 655 nm shows CW laser operation around 3.5 μm.

Article Zur kristallchemischen Einordnung von NaSbCl6, NaNbCl6« und NaTaCl6 was published on July 1, 1992 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 198, issue 1-4).
Synthesis and characterization of aromatic polymers containing pendant silyl groups. I. Polyarylates
Abstract Polyarylates containing pendant silyl group were prepared by the phase‐transfer catalyzed, two‐phase polycondensations of 2,2‐bis (4‐hydroxyphenyl) propane with corresponding dicarbonyl chlorides such as 2‐trimethylsilylterephthaloyl chloride, 5‐trimethylsilylisophthaloyl chloride, 5‐dimethylphenylsilylisopht…
Phase diagram exhibiting a smectic-A–smectic-C–smectic-Fmeeting point
We report an observation of a smectic-A--smectic-C--smectic-F (A-C-F) meeting point in a binary liquid-crystalline system. Detailed high-precision x-ray measurements enabled us to characterize the meeting point as a triple point, a point at which the three phases coexist. A direct consequence of this result is the exi…

Hydrogen based reactive ion etching of zinc sulfide
II–VI materials are important for optoelectronic devices. These devices are currently wet etched and due to the isotropic nature of wet etching, their etch geometries are limited. Reactive ion etching (RIE), a dry etch process, is a more desirable alternative, because it offers a means of producing small anisotropic s…
Shrinkage of atomic distances in ultrathin a-SiO2 film
Substrate-free a-SiO2 films, 480 Å in thickness, have been made by means of electron beam evaporation. Electron diffraction patterns, taken under the condition that the incident beam is normal to the films, are all centre-symmetric, while their intensity features vary considerably with the film thickness. Since a film…
High pressure studies on single crystals of zirconium sulphoselenides
Electrical resistance measurements have been performed on ZrS2, ZrSe2, and ZrSSe single crystals grown by Iodine vapour transport technique in the pressure range 10 kilobar to 80 kilobar (1 GPa-8GPa). It is observed that all these crystals show a decrease in resistance with increase in pressure. The results have been…
YTTRIUM ALUMINATE CERAMIC FIBERS VIA PRE-CERAMIC POLYMER AND SOL-GEL ROUTES
Yttrium aluminum garnet (YAG - Y3Al5O12) fibers have been prepared by dry spinning solutions of yttrium and aluminum carboxylate polymers (precursor route) and by dry spinning aqueous oxide sols (sol-gel route). Fibers from aqueous diphasic gels are prepared by mixing a colloidal alumina sol containing 50-nm hydrous a…
Structure and phase transitions in poly[bis‐(2,2,3,3‐tetrafluoropropoxy) phosphazene]
Abstract The structure and phase transitions in poly[bis‐(2,2,3,3‐tetrafluoropropoxy)phosphazene] have been studied by differential scanning calorimetry (DSC) and x‐ray diffraction. Two crystalline phases and one mesomorphic phase are found, denoted I, II, and III, respectively. These phases convert reversibly one int…
Utilization of Alcohols for the Dehydration of Magnesium Chloride
Two processes are proposed for preparing anhydrous magnesium chloride by use of alcohols. Some alcohols can replace water to form coordinates with MgCl2, and make the dehydration of magnesium chloride much easler. The possibility of dehydration by alcohol distillation is discussed, and n-butanol was found to be the pr…
Quantitative Fiber Mixture Analysis by Scanning Electron Microscopy
Labeling textile blends requires identification and quantification of their fibrous components. Blends of specialty animal fibers with sheep's wool are of special, practical importance; for these the light microscope is the traditional tool of analysis. To investigate the actual applicability of light microscopy for a…
Advances in NDI Elastomer Chemistry
Since its first commercial use in the early fifties naph thalene-1,5-diisocyanate (NDI) has been used almost exclusively in combina tion with polyadipate diols. The corresponding prepolymers crosslinked with 1,4-butanediol give solid NDI elastomers; crosslinking with water results in microcellular elastomers. NDI/este…
Non-stoichiometry effects in the properties of (NH4)3H(SeO4)2and (NH4)4H2(SeO4)3crystals. Dielectric and ESR studies
Large (NH4)H(SeO4)2 crystals and (NH4)4H22(SeO4)3 crystals grow usually from non-stoichiometric solutins with an excess of selenate acid. Complex dielectric anomalies at crystal phase transitions and suggest some kind of impurity in the crystal lattice. X-band ESR measurements of γ-irradiated single crystals identifie…
Ring Pattern Formation in 2- d Shear of Freely Suspended Films of a Smectic C Liquid Crystal
Space-time diagrams are used to analyze the dynamics of the liquid-crystal smectic C director in two-dimensional shear. We find a steady-state ring pattern only persists if there are no broken rings. A pair of defects, disclinations, is created when a ring breaks. With broken rings, the pattern dynamics is a sensitive…
Polymer gel films with simple organic electrochromics for single‐film electrochromic devices
Abstract Polymer gel films [poly(1‐vinyl‐2‐pyrrolidinone‐co‐ N,N ′‐methylenebisacrylamide) (PVPD)] which contain simple organic electrochromics [ p ‐diacetylbenzene ( p ‐DAB), dimethyl‐ or diethyl terephthalate ( p ‐DMP or p ‐DEP)] are prepared and their optical responses to applied voltage are investigated. p ‐DAP/PV…

Room-temperature M\"ossbauer spectra have been measured for icosahedral (i-phase) ${\mathrm{Al}}_{65}$${\mathrm{Cu}}_{20}$${\mathrm{Fe}}_{15}$ and iron-doped decagonal (T-phase) ${\mathrm{Al}}_{65}$${\mathrm{Cu}}_{15}$${\mathrm{Co}}_{20}$ quasicrystals. The observed T-phase spectrum is qualitatively different from any…
