The cross-linking reaction of 15 dimethacrylates, one trimethacrylate and five diacrylates was studied by means of differential scanning calorimetry (DSC) and high performance liquid chromatography (HPLC) to investigate the relationship between the polymerization characteristics and the chemical structure of these mon…
Hexagonal colloidal copper particles with a narrow size distribution are formed in the reduction of an acetonitrile solution of Cu(OAc) 2 ·H 2 O with hydrazine hydrate in the presence of poly(vinyl‐2‐pyrrolidone). The deep‐red sols, which were characterized by electron microscopy, are extremely stable in an inert gas…
Magnetic susceptibility has been measured in ${\mathrm{Pb}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Mn}}_{\mathrm{x}}$Te, ${\mathrm{Pb}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Mn}}_{\mathrm{x}}$Se, and ${\mathrm{Pb}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Gd}}_{\mathrm{x}}$Te with values of x fr…
Powder diffraction techniques are potentially extremely useful for the characterization of a variety of metallic thin films which are used as interconnection materials in very large scale integrated (VLSI) devices. Phase identification, texture determination, elastic strain measurement, and grain size distribution can…
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…
