The suitability of photodegradation and biodegradation technolo gies for specialty applications is discussed. The research on degradable polymers is reviewed with emphasis on the processes of photooxidation, pho tostabilization and photosensitization. The degradation mechanisms, reaction products, analytical procedure…

An X-ray powder diffractometer has been modified by the addition of a narrow-bandpass germanium pre-monochromator and a linear position-sensitive detector (LPSD) with its centre set at the normal θ –2 θ focusing condition. Diffraction data are recorded using a step-scan procedure in which the patterns recorded at each…

The transition from rhombohedral phase to tetragonal in screen-printed lead zirconate titanate (PZT) thick films was studied using Raman-scattering spectroscopy, and the results were compared with those of x-ray-diffractometry investigations. The unfired films were subjected to rapid firing in an air atmosphere at tem…

We make a theoretical study of the chevron and tilted structures in the smectic-A phase of a liquid crystal. These structures have been observed to occur in cells in which the director is oriented in the plane of the wall. We examine the hypothesis of Limat and Prost [Liq. Cryst. 13, 101 (1993)] that the layer bucklin…
The reversible photoisomerization and the thermal isomerization of azobenzene-based (Az.b.) groups covalently bound to (meth)acrylic (co)polymers were investigated in thin films. For the amorphous polymers it was found that a broad range of the thermal cis --> trans isomerization rates could be obtained by varying…
Abstract An efficient method for quantitative XPS analysis is the so‐called multiline approach. This method does not require standards, it takes into account the instrumental and matrix effects and it derives quantitative information from statistical analysis of all photoelectron intensities visible in the spectra. On…

We have studied (LuC${)}_{2}$(${\mathrm{Ni}}_{2}$${\mathrm{B}}_{2}$) and (LuC)(${\mathrm{Ni}}_{2}$${\mathrm{B}}_{2}$) at ambient and high pressures. Superconductivity was discovered in (LuC${)}_{2}$(${\mathrm{Ni}}_{2}$${\mathrm{B}}_{2}$) at 2.9 K. Pressure was found to suppress both the electrical resistivity and the…
The spreading of a thin drop of fluid that partially wets a plane surface is calculated. Capillarity, slip, and intermolecular forces are included in the model, and it is shown that a complete solution is possible without having to exclude the vicinity of the contact line and without having to assume the dynamic behav…
Superplastic SiAlON's of the nominal composition Y m /3 ‐Si 12‐( m + n ) AL m + n O n N 16– n are reported in this study using a transient‐phase‐forming approach. They encompass the fields of single‐phase α′‐SiAlON, single‐phase β′‐SiAlON, and their two‐phase mixtures. Excellent formability is obtained at 1550°C for t…
Grain boundary engineering is based on the fact that special grain boundaries (i.e. low Σ CSL) may have beneficial physical and chemical properties. It is now possible to increase and characterize the fraction of low Σ interfaces in polycrystalline materials, thereby improving their bulk properties by controlling the…
Results of optical-absorption experiments on heavily irradiated NaCl single crystals are presented. The dose rates were between 4 and 250 Mrad/h; the doses between 1 and 7 Grad. The irradiation temperatures were in the range of 20--150 \ifmmode^\circ\else\textdegree\fi{}C. Because of the intense optical bands, the thi…
We argue that the possibility to observe a stable biaxial nematic phase in a binary \nmixture of prolate and oblate hard particles is seriously limited by the existence of entropydriven \ndemixing. This result follows from a simple Onsager-type density functional theory. An \nimportant feature15 the coupli…
