The consolidation behavior of flocculated alumina suspensions has been analyzed as a function of the interparticle energy. Consolidation was performed by a centrifugal force field or by gravity, and both the time‐dependent and equilibrium density profiles were measured by a gamma‐ray absorption technique. The interpar…

Ultra-high-strength poly(L-lactide) (PLLA) rods were fabricated using a drawing technique. Rods with a diameter of 3.2 mm and a draw ratio of 2.5:1 showed initial bending strength and modulus values of 240 MPa and 13 GPa, respectively. The purpose of this study was to investigate the in vitro and in vivo degradation o…
In a combined theoretical and experimental study, the energies and structures of σ = 3, [011] tilt boundaries in Cu were investigated. Equilibrium atomistic structures and grain-boundary energies were calculated by static energy minimization using an embedded-atom potential. Cu bicrystals of the same boundary orientat…
The structure of the electron-transfer protein, plastocyanin (99 amino acids, one Cu atom, 10,500 Da) from poplar leaves, has been refined at 1.33 A resolution to a residual R = 0.15. The space group is orthorhombic, P2(1)2(1)2(1), a = 29.60 (1), b = 46.86 (3), c = 57.60 (3) A. The 14,303 reflections used in the refin…
Abstract The major morphological changes during polymer blending occur during the initial softening stage. This work explains the evolution of phase morphology of polymer blends from pellets to submicron particles in a co‐rotating twin‐screw extruder. The extruder was opened and blend samples were taken along its leng…

The current knowledge on the structure and on the organization of polyhydroxyalkanoic acid (PHA)-biosynthetic genes from a wide range of different bacteria, which rely on different pathways for biosynthesis of this storage polyesters, is provided. Molecular data will be shown for genes of Alcaligenes eutrophus, purple…

A number of critical regulatory proteins in both prokaryotic and eukaryotic cells are subject to rapid, energy-dependent proteolysis. Rapid degradation combined with control over biosynthesis provides a mechanism by which the availability of a protein can be limited both temporally and spatially. Highly unstable regul…
