The third‐order nonlinear optical susceptibilities, X (3) , of the xLaO 1.5 ·(100 – x)TeO 2 binary glasses have been measured by the third harmonic generation (THG) method. In order to investigate the origin of high‐intensity third harmonic generation, the various optical properties, such as nonlinear refractive index…

Abstract Neben den Polyisoprenoiden, Polypeptiden, Polysacchariden und Polynucleotiden kommt in der Natur eine weitere Gruppe von Biopolymeren, die Poly(hydroxyfettsäureester), vor. Obwohl der häufigste Vertreter, Poly[(R)‐3‐hydroxybuttersäure| P(3‐HB), von Lemoigne schon in den zwanziger Jahren als Speichermaterial d…
Large cavities with segregated hydrophobic and hydrophilic domains result from the inclusion of inorganic and organic canons in the hydrothermal synthesis of the blue compound 1. Its structure is shown in the picture on the right.
The orientation characteristics of polypropylene are studied with respect to annealing temperature, orientation temperature, stretch ratio and mode of extension, in order to determine optimum orientation conditions.
Polyimides containing imide and (p-phenoxy)imide side groups were obtained by the interaction of new aromatic tetramines, bis[3-amino-4-(p-aminophenoxy)]arylenes, with equimolar amounts of aromatic tetracarboxylic acid dianhydrides and twofold molar amounts of aromatic dicarboxylic acids anhydrides. Structures and pro…
The aim of this study is to develop a kinetic model for the quantitative evaluation of, and to examine dose dependency in liposome degradation in blood circulation in vivo. Multilamellar liposomes labeled with 3H-inulin were administered intravenously into rats and the time courses of blood concentration and urinary e…
Abstract The use of polymeric materials in building or construction applications is steadily increasing. Therefore, the potential for these materials to be exposed to fire is also increased. The understanding of the pyrolysis characteristics of these materials is thus a necessity. There are many standard tests used to…
X-ray photoemission measurements of high purity CuF2 are presented. XPS studies of Cu compounds in this laboratory have been motivated by the need to identify species on chemically-etched high temperature superconductor surfaces [see R. P. Vasquez, M. C. Foote, and B. D. Hunt, J. Appl. Phys. 66, 4866 (1989)].
An energy filtering transmission electron microscope (EFTEM) has the advantage that, unlike a conventional TEM, it can also utilize the spectroscopic information carried by inelastically scattered electrons, thus making optimum use of all the available information. The design of an EFTEM featuring an Ω‐type imaging el…

Abstract The inherent asymmetry of many powder diffraction profiles has been a principal hindrance in extending the application of diffraction techniques. The resurgence of developments in this area in recent years is primarily the result of the availability of general algorithms permitting computer automation of powd…
Oxidation of chemically vapor‐deposited Si 3 N 4 was studied in dry oxygen between 1923 and 2003 K under a total pressure of 0.1 MPa using a thermogravimetric technique. At 1923 to 1953 K, a parabolic rate mechanism prevailed for the oxidation reaction. From 1973 K, the oxidation reaction exhibited a mixed linear‐para…
SUMMARY In this paper it is shown that CO2 can effectively displace oil from diatomite under countercurrent conditions. A simple model is presented which quantitatively matches the observed oil production. CO2 is postulated to contact the oil due primarily to diffusive transport, and the diffusion coefficient used is…
