The gradual shift from biostable prostheses to degradable, temporary implants represents one of the most significant trends in biomaterials research. In view of this trend, medical applications of degradable implant materials were reviewed with special emphasis on orthopedic polymeric implants. Among the polymeric imp…

We have designed and built an imaging filter which can be attached to most stan- dard TEMs, and is capable of operating at primary energies of up to 400 keV. The filter uses a 90m agnetic sector prism, a piezoelectrically controlled energy-selecting slit, and 6 quadrupole and 5 sextupole lenses. It fully corrects seco…
The structure of mullite was refined by the Rietveld method, and a new method for the estimation of chemical composition of mullite was proposed. Mullites were synthesized by firing the starting materials prepared by sol–gel and spray pyrolysis methods at various temperatures. Linear correlations were recongnized betw…
Abstract Physical properties of blown films (25‐60‐μm thickness) from compounded mixtures of linear low‐density polyethylene (LLDPE) and starch were investigated. As starch content increased, tensile strength, percent elongation, and light transmittance decreased and film thickness increased. Among the tested films, s…

A detailed study of protonic conductivity in Nd-doped BaCeO3 is made using water-uptake and galvanic-cell measurements to supplement the conductivity results. Samples were pretreated at 900°C at different PH2O atmospheres and the conductivity measured with a frozen-in proton concentration. Isotope effect (D2O versus H…
The phase evolution, under thermal treatment, of the 12-molybdo(tungsto)phosphoric acids and their related 1-vanado-substituted compounds has been studied by in situ X-ray diffraction methods. The anhydrous acid temperature range is clearly observed for the 12-molybdo(tungsto)phosphoric acid parents via formation of a…

Nanocrystalline (nc) metals show significant differences in their thermodynamic properties, such as specific heat at constant pressure and thermal expansion, in comparison to polycrystalline metals. These properties are explained in terms of a macroscopic analysis. Based on a quasiharmonic approximation, the thermodyn…

Submicrometer SiC ( β ‐form) powders were synthesized by reacting silica and carbon black at temperatures between 1450° and 1800°C. Simultaneous application of vacuum and mixing provides the condition for full conversion of silica to SiC. It was shown that two different reaction mechanisms are possible, depending on t…

As fragments of the V2O5 layer structure (shown right; spheres for bridging O atoms are large and shaded, for terminal O atoms large and open, and for V atoms small and open) the recently prepared, novel polyvanadate structures mentioned in the title are reported and systematized. In contrast to the classical polyoxoa…
