    摘要： A capacitor with alterable capacitance for changing the impedance of a section of a coplanar waveguide, which may be used in particular as a high-frequency microswitch, is provided. A ground lead and a signal lead interrupted by an electroconductive connection which is self-supporting at least in some areas are provided, the capacitor including the electroconductive connection and an additional electroconductive connection connected to the ground lead. A structure connected to the electroconductive connection is provided, which is designed in such a manner that it reduces mechanical stresses which occurs in the electroconductive connection. An exemplary embodiment of the device provides for the electroconductive connection to be made of a material having coefficients of thermal expansion similar to that of silicon and a high modulus of elasticity compared to metals, in particular of molybdenum, tantalum or tungsten. The two exemplary embodiments may be combined.

    摘要： Magnetic glass particles are prepared containing a magnetic core coated with a glass layer having a substantially pore-free glass surface. The particles are used for separating biological material such as nucleic acids. A preferred process of preparing the particles is by forming a mixture of magnetic cores with a sol formed from an alcohol and a metal alkoxide, spray-drying the mixture to coat the cores with a layer of gelled sol, and heating the coated cores to obtain the magnetic glass particles. Preferably, the particles have an average particle size of less than 100 &mgr;m and any pores of the glass surface have a diameter of less than 10 nm. The magnetic core may be a composite material containing a mica core and magnetite particles immobilized on the mica core, and the glass layer may contain boron oxide. Magnetic core materials include magnetite (Fe3O4) and Fe2O3. In using the magnetic glass particles to separate a biological material, the particles are contacted with a fluid containing the biological material such that the biological material binds to the glass surface, and the bound biological material is separated from the fluid such as by using a magnetic field. Before applying a magnetic field, the magnetic particles may sediment when contacted with the biological material.
