How to fill space with atoms in condensed matter Real quasicrystals: preparation and characterization High-dimensional crystallography Where are the atoms? Phonons, phasons, and dislocations in quasicrystals A little more about the physics of quasicrystals.
Photoluminescence under 7.9-eV excimer-laser excitation was measured at room temperature on various types of high-purity silica glasses, which were classified based on the oxygen stoichiometry and OH concentrations. Several luminescence bands with different peak energies from 1.9 to 4.3 eV and decay constants were obs…

Effect of chitosan coating on decay of strawberry fruits held at 13 C was investigated. Strawberry fruits were inoculated with spore suspensions of Botrytis cinerea or Rhizopus stolonifer and subsequently coated with chitosan solutions (10 or 15 mg/ml). After 14 days of storage, decay caused by B. cinerea or R. stolon…
The use of nanocomposites in materials processing can lead to monophasic or multiphasic ceramics, glasses or porous materials, with tailored and improved properties. This review deals with a variety of nanocomposites such as sol–gel, intercalation, entrapment, electroceramic and structural ceramic types, which exhibit…
A regioselective synthetic method to poly(3-alkylthiophenes) provides structurally homogeneous poly(3-dodecylthiophene), which upon oxidation with I2 leads to polymers with average conductivities of 600 cm–1 and maximum conductivities of 1000 S cm–1.
Gallium nitride was studied by Raman scattering and x-ray-absorption spectroscopy up to 60 GPa. A high-pressure structural phase transition was observed in gallium nitride at 47 GPa by means of Raman scattering and x-ray-absorption spectroscopy. We also report the direct determination of the bulk modulus ${\mathit{B}}…
Abstract Various copper and zinc compounds (Cu, Zn, CuZn alloy, Cu 2 O, CuO, Cu 2 S, ZnO, ZnS) have been synthesized and characterized by electron spectroscopy (XPS). Data on the 2 p 3/2 levels of Cu, Zn and S, the 1s level of O, the L 3 M 45 M 45 Auger transitions of Cu and Zn, the valence bands and the modified Aug…
The authors describe how the various model parameters needed to describe hysteresis on the basis of the Jiles-Atherton theory can be calculated from experimental measurements of the coercivity, remanence, saturation magnetization, initial anhysteretic susceptibility, initial normal susceptibility, and maximum differen…
The development of phytoplankton communities was studied in floating enclosures. The enclosures were supplied with either surface water or water from 40 m depth. Nutrients with or without silicate were added in some of the experiments, while others recieved no artificial fertilization. It is shown that diatom dominanc…

ABSTRACT An edible wheat gluten film was developed and effects of gluten concentration, ethanol concentration (ET) and pH of the film‐forming solution on various film properties were evaluated using Response Surface Methodology. pH and ethanol concentration had strong interactive effects on film opacity, water solubil…
The antibacterial action of chitosan hydroglutamate (CH), chitosan lactate (CL) and chitosan derived from fungal mycelia was examined against both gram‐negative and gram‐positive bacteria. Plate counts indicated inactivation rates of one‐ to five‐log‐cycles within one hour. Fungal chitosan had significantly less antib…
We report femtosecond time-resolved pump-probe reflection experiments in semimetals and semiconductors that show large-amplitude oscillations with periods characteristic of lattice vibrations. Only ${\mathit{A}}_{1}$ modes are detected, although modes with other symmetries are observed with comparable intensity in Ram…
We propose a novel approach that allows efficient numerical simulation of systems consisting of flexible chain molecules. The method is especially suitable for the numerical simulation of dense chain systems and monolayers. A new type of Monte Carlo move is introduced that makes it possible to carry out large scale co…
The theory of the contact angle of pure liquids on solids, and of the determination of the surface free energy of solids, γs, is reviewed. The basis for the three components γLW s, γ⊕s, and γ⊖s is developed, and an algebraic expression for these properties in terms of measured contact angles is presented. The inadequa…

X-PLOR is a highly sophisticated computer program that provides an interface between theoretical foundations and experimental data in structural biology, with specific emphasis on X-ray crystallography and nuclear magnetic resonance spectroscopy in solution of large biological macro-molecules. This manual to X-PLOR Ve…
The behavior of solid and liquid matter at high pressures and temperatures is best described in a phase diagram, which shows the regions of stability of different phases of the material. Thanks to the diamond-anvil cell, which has made possible much higher pressures, and to new and very accurate theoretical models and…
We have fabricated epitaxial ferroelectric PbZr0.2Ti0.8O3/YBa2Cu3O7−x heterostructures on single crystalline [001] LaAlO3. Only the (00l) peaks of the PbZr0.2Ti0.8O3 (PZT) film are observed, indicating that the epitaxial, c-axis oriented YBCO film is a good structural template for the heteroepitaxial growth of PZT fil…
