The sintering behavior of doped manganite powders was found to be highly dependent on changes in calcination conditions and A/B cation ratio. Coarsening of combustion synthesized powders by calcination allowed for higher green densities in dry‐pressed compacts, which resulted in higher sintered densities for powders c…
Single crystal silicon field emitters have been modified by surface deposition of diamond using bias-enhanced microwave plasma chemical vapor deposition. Polycrystalline diamond with a high nucleation density (1010/cm2) and small grain size (<20 nm) was achieved on silicon field emitters. Field emission from th…

The affine transformation model---formulated for ellipsoidal particles with axis ratio Q and previously used for the calculation of the viscous properties of nematic liquid crystals with perfect orientation order---is generalized to realistic uniaxial phases with imperfect order (Maier-Saupe order parmeter S1). For th…

Processible organic materials exhibiting high charge carrier mobilities are a step closer with the development of liquid crystalline photoconducting materials. The mobilities have been measured in various phase regions over the temperature range from – 100 to 165°C and the influence of different annealing conditions a…

Summary Alumina/SiC nanocomposites were produced by mechanical mixture of commercial powders. The preparation steps involved the vigorous mixing of the powders and drying under conditions where the homogeneous mixture was kept stable. Pressureless sintering of die‐pressed powders achieved reasonable densities (∼97% th…
The temperature at which collagen denatures from a triple helix to a random coil structure is a useful measure of the degree of crosslinking. A new multi-sample denaturation temperature tester (DTT) has been constructed for rapid determination of the collagen denaturation temperature of natural tissues and collagenous…

Quantitative determination of phase abundances using X-ray powder diffraction is a technique in wide use today. Of the various methods employed, the Chung, or RIR method, is one of the most common because it can provide reliable results for all sample types. However, improvements can be made to the Chung method of ana…

Condensed phases of Langmuir monolayers are treated in the framework of the Landau theory of phase transitions as a result of successive ordering of the hexatic phase. All types of ordering allowed by symmetry and the couplings between them are described. The phase diagrams and x-ray structural data on monolayers of v…
