Advanced sorbents for water purification need to be developed for environmental protection. Porous boron nitride (BN) is a high-end material for the removal of pollutants for its remarkable sorption characteristics and chemical inertia. However, it still suffers from thick pore walls, low yield and powdery state, limiting the performance.Web

The typical levels of boron in the raw water supplying AMD's facility in Austin, Texas are in the neighborhood of 0.25 ppm. Since boron is used in the production of microprocessors as a doping agent, AMD decided that any boron that remained in the Ultrapure Water (UPW) used in FAB 25 might be detrimental to the performance and yield of product.Web
