Abstract: A process disclosed herein is related to the isolation and purification of substantially pure chemicals, including silica gel, sodium silicate, aluminum silicate, iron oxide, and rare earth elements (or rare earth metals, REEs), from massive industrial waste coal ash. In one embodiment, the process includes a plurality of caustic extractions of coal ash at an elevated temperature, followed by an acidic treatment to dissolve aluminum silicate and REEs. The dissolved aluminum silicate is precipitated out by pH adjustment as a solid product while REEs remain in the solution. REEs are captured and enriched using an ion exchange column. Alternatively, the solution containing aluminum silicate and REEs is heated to produce silica gel, which is easily separated from the enriched REEs solution. REEs are then isolated and purified from the enriched solution to afford substantially pure individual REE by a ligand-assisted chromatography.

Abstract: The present invention relates to resist compostions, in particular to photoresists that can be used in photolithography, especially in the fabrication of integrated circuits and derivative products. The resist compositions of the invention include an anti-scattering component which has a significant amount of empty space, and thus fewer scattering centers, such that radiation-scattering events are more limited during exposure. Such anti-scattering effects can lead to improved resolutions by reducing the usual proximity effects associated with lithographic techniques, allowing the production of smaller, higher resolution microchips. Furthermore, certain embodiments involve anti-scattering components which are directly linked to the resist components, which can improve the overall lithographic chemistry to provide benefits both in terms of resolution and resist sensitivity.
