摘要:
The present invention relates to a method for the wet chemical preparation of materials libraries consisting of a large number of solids, the solids being deposited from reaction mixtures in microreaction chambers onto a bottom plate which simultaneously serves as the library substrate. Depending on the material selected for the library substrate, the solids can subsequently be examined non-destructively, for example, by reflecting or penetrating microarea X-ray diffraction.

摘要:
An optical recording medium contains, on a base, one or more dyes and a polymer which forms liquid-crystalline phases.The information is written into the uniformly oriented liquid-crystalline polymer layer, for example by means of a laser. During this procedure, the polymer heats up locally to above a phase transition temperature. By cooling, the resulting change is frozen in the glass state.The information can be erased by applying an electric field and/or heating.The recording material permits high-contrast storage and possesses high sensitivity, good resolution and excellent stability.
