Submicrometer alumina powders, of both standard and narrow particle‐size distributions, were consolidated by dry‐pressing and colloidal‐forming techniques. The resulting green compacts were characterized in terms of pore‐size distribution, green density, shrinkage behavior, and sintered density. The interrelationships…
Many of the genes of simple organisms with small genomes are encoded on opposite DNA strands so that the genes either overlap or one gene is nested within another gene (Normark, S., Bergström, S., Edlund, T., Grundström, T., Jaurin, B., Lindberg, F.P., and Olsson, D. (1983) Annu. Rev. Genet. 17, 499-525; Chen, C., Mal…

The mostly crystallized Si:H having a wide optical band gap and showing a visible photoluminescence at room temperature, has been fabricated by means of a planar magnetron rf sputtering technique in hydrogen gas onto a low temperature (about 100 K) substrate. The materials consist of very small crystalline silicon par…

The dislodging by dynamic pressure forces of a drop adhered by surface tension to a plane is analysed. An integro-differential equation describing the drop shape is solved numerically and the critical Weber number as a function of contact angle hysteresis is found.

A design is presented of a high-angle fully eucentric tilting stage (±45. ±23° around two orthogonal axes) for a transmission electron microscope. The concurrent design of suitable objective-lens pole pieces has been made in order to get the best compromise between electron optical performances and the difficulties in…
The advantages of piezoelectric actuators are often opposed by one decisive handicap: their high control voltage. Piezoelectric multilayer ceramics do not show this disadvantage. Their highest possible deflection can be gained with voltages between 5 and 15 V which are common in today's electronics.
Summary Two model compounds, n-dodecylpyridinium bromide (n-DDPB) and l-octyn-3-01, were tested in HCI acid as inhibitors for J55 oilfield steel. This paper describes the kinetic and chemical analyses conducted to arrive at inhibition mechanisms for these model compounds. These studies show that the pyridinium forms a…

A tissue-specific casein kinase, purified from the Golgi-enriched-membrane fraction of guinea-pig lactating mammary gland (GEF-CK), readily phosphorylates the synthetic peptide Ser-Glu5, a good substrate of casein kinase-2, and several derivatives varying for the number and position of acidic residues on the C-termina…
An Au cluster with an unusual structure, the dication 1, is formed in the polyauration of 2,4,4-trimethyl-4,5-dihydrooxazole. The expected dihydrooxazole with a peraurated 2-methyl group reacts further with excess Ph3PAuCl/CsF under Au1-incorporation to give 1. The highly aurated C atoms are trigonal-bipyramidally coo…
Abstract Using combined optical‐spectroscopic and transport investigations it is succeeded for the first time to determine all relevant valence band data for the whole series of mixed crystals (Bi 1− x Sb x ) 2 Te 3 (0 ≦ x ≦ 1). The reflectivity of polarized infrared light including its anisotropy is measured in the w…
Abstract The nonlinear viscoelastic behavior of glassy polymers and its relationship to ductile yielding is studied by single‐ and double‐step stress relaxation experiments. In the latter case a small stress relaxation step is superimposed on a specimen at an elevated state of temperature or strain. The results show t…
