Improved Thin Film
Background Thin film deposition of metal oxide materials from aqueous solution is challenged by the solubility and gelling behavior of precursors. For example, some metal cations are poorly soluble at neutral pH, but added acid or base is detrimental to substrate stability and film adherence. In addition, soluble salts of metal cations tend to crystallize...

Process for Recycling PVC to HDPE
Background Approximately 40 million tons of polyvinyl chloride (PVC) are produced annually, making PVC one of the most widely produced synthetic plastic polymers. Waste materials that contain PVC are extremely difficult to recycle mechanically. Thermochemical methods such as pyrolysis are also undesirable because of hydrochloric acid and chlorinated...
