A method of making metal oxide ceramic material is disclosed by which the porosity of the resulting material can be selectively controlled by manipulating the sol used to make the material. The method can be used to make a variety of metal oxide ceramic bodies, including membranes, but also pellets, plugs or other bodies. It has also been found that viscous sol materials can readily be shaped by e...

Improvements to the polymerase chain reaction (PCR), a process for in vitro enzymatic amplification of specific nucleic acid sequences, can be achieved by changing the way that PCR reagents are mixed and the enzymatic reaction is started and by the replacement of mineral oil, commonly used as a vapor barrier to minimize solvent evaporation, by a grease or wax. The use of such mixtures allows for t...

The novelty is that: (a) the system incorporates a pre-settling tank (2) and a pre-storage holding tank (4); (b) t...

Optical transmitters for multiplex operation require laser arrays working on the basis of different values of a laser-characteristic variable, i.e. the emission wavelength. In order to prevent cross influences, existing arrays only allow for simultaneous or graded operation of the laser. Moreover, the corresponding coupling networks use up a large part of the optical output power. It is also known...

The semiconductor component (8) is operated in temperature-controlled surroundings with a preset current, dependent on a set temperature value (Tsoll). The temperature of the component is detected and is compared with a voltage given by the set temperature value. The surrounding temperature of the component is controlled on the basis of the difference of the two voltages. An Independent claim is i...
