摘要:
A base body contains a substrate that is at least partially coated with a carbon-containing layer. The carbon-containing layer is at least partially functionalized with a molecule that is bound directly or via at least one linker or functional group to the carbon-containing layer. The base body, which has a functionalized carbon-containing surface, is capable of influencing biological processes during a corresponding functionalization.

Particles and monoliths are used for providing an ionized analyte for mass analysis by photon desorption having a size in the range of 0.5-100 μm, wherein the particles or monoliths are modified with a chemical compound capable of absorbing photons having a wave-length of at least 300 nm. The particles and monoliths allow the use of MALDI-MS for the high throughput screening of molecules having a molecular weight lower than 700 μ without interfering signals or with only a limited number of background signals.
摘要:
A heat dissipation arrangement for chip modules on multilayer ceramic substrates, in particular multichip modules, in which passages for a heat-conducting medium are provided in the ceramic substrate. The multilayer ceramic substrate is mounted on a metal heat sink. Thermal passages, in particular in the form of a hole pattern or array, are provided in the top layer of the multilayer ceramic substrate, in the region of the chip to be mounted. A cavity functioning as an evaporation chamber is provided in the layer of the multilayer ceramic substrate directly beneath the top layer, in the region of the chip to be mounted, and a trough-shaped recess functioning as a condenser is provided in the metal heat sink, in the region of the chip to be mounted. In the layers of the multilayer ceramic substrate located between the evaporation chamber and the condenser, in the region of these two chambers, a series of large steam channels and small condensate channels, the latter functioning as capillaries is provided, which interconnect these two chambers. This arrangement forms a miniaturized heat pipe structure which can transport a great amount of energy per unit of time across short distances.
