摘要:
A method for fabricating electronic devices includes the steps of 1) printing a multi-layer electronic device on a silicone-based hard coating on a substrate, and 2) removing the device from the substrate. The silicone-based hard coating is an abrasion resistant coating with hardness ranging from 1 to 10 gigaPascals.

摘要:
Samples of materials used in industrial processes are analyzed to determine the concentration of certain materials of interest. The quantitative analysis of samples for these materials is provided without the need for manual methods such as titration. Indicators such as fluorescent dyes for which the intensity of fluorescence is indicative of the concentration of a material of interest are used. The dyes are made to fluoresce by means of a light source, and a photomultiplier or other detector capable of measuring light intensity detects the resulting fluorescence. The intensity of fluorescence in the sample is compared to the intensities of fluorescence produced by samples with known concentrations of the material of interest to determine the concentration of the material of interest of the sample.
