Abstract: Films with optical transmittance of >80% between 400 and 750 nm and with CTEs less than 20 ppm/° C. are prepared from aromatic polyamides that are soluble in polar organic solvents yet have Tgs >300° C. The films are crosslinked in the solid state by heating at elevated temperatures for short periods of time in the presence of multifunctional epoxides. Surprisingly, the optical and thermal properties of the films do not change significantly during the curing process. The temperature required for the crosslinking process to take place can be reduced by the presence of a few free, pendant carboxyl groups along the polyamide backbones. The films are useful as flexible substrates for electronic displays and photovoltaic devices.

Abstract: A method for preparing uniquely sized nanoparticles of CaF2 by simultaneously spray drying a first NH4F and a biocompatible salt solution and a second Ca(OH)2 and biocompatible salt solution to form CaF2 solid particles in a soluble salt matrix wherein the salt is more soluble than CaF2. The salt matrix may then be dissolved and the separate CaF2 nanosized particles collected for use as a dental therapeutic material. The technique is useful in the preparation of other discrete, nanoparticle sized compounds and combinations by carefully choosing the solvents and solutes of the two spray dried solutions.

Abstract: A test device for an electronic product comprises a vertical pressing pole having a pushing end. The test device also comprises a movable platform with a sticking point, wherein upward movement of the movable platform moves the vertical pressing pole upwards by the sticking point. The vertical pressing pole passes through a balance weight which rests on the sticking point. A pressurized platform bears pressure from the pushing end, when the pushing end is pushed onto the pressurized platform. A load-bearing platform supports the pressurized platform and the electronic product located below the pressurized platform. The product is pressed between the pressurized platform and the load-bearing platform due to the pressure from the pushing end lying on the pressurized platform. When the movable platform is further moved downwards after the pushing end is on the pressurized platform, the sticking point bearing the balance weight is separate from the movable platform.
