摘要： In one aspect, separation media are described herein operable for removing one or more water contaminants including NOM and derivatives thereof. Briefly, a separation medium includes a nanoparticle support and an oligomeric stationary phase forming a film on individual nanoparticles of the support, the film having thickness of 1 to 100 nm. In some embodiments, oligomeric chains of the stationary phase are covalently bonded to the individual nanoparticles.

摘要： In one aspect, separation media are described herein operable for removing one or more water contaminants, including NOM, fluorinated chemicals, and/or derivatives thereof. Briefly, a separation medium comprises a silica-containing granular support; and an oligomeric stationary phase forming a film on individual grains of the granular support. In some embodiments, the oligomeric stationary phase comprises oligomeric chains covalently bound to the individual grains.

摘要： In one aspect, systems and methods for the efficient and cost-effective removal of bromide from wastewater streams are described herein. Briefly, a system for bromide removal comprises pretreatment apparatus operable for at least partial removal of background ionic species from the wastewater stream and/or dilution of the background ionic species in the wastewater stream. The system also comprises bromide capture apparatus operable for removal of bromide from the pretreated wastewater stream, wherein the system removes bromide from the wastewater stream at an efficiency of at least 80 percent. In some embodiments, bromide is recovered from the capture apparatus and reused in flue gas treatment applications.

摘要： A system and method for testing firearm operating characteristics are provided using a force testing apparatus coupled to all or a portion of the firearm. Of significance, the system and method are configured to test the interaction(s) of multiple firearm components during operation without a live round such that firearm component defects, manufacturing tolerance problems, misalignments, and the like can be discovered during or subsequent to manufacture and prior to use.
