Metal-assisted chemical imprinting (Mac-Imprint) is a contact-based wet etching process that combines metal-assisted chemical etching (MACE) and nanoimprint lithography (NIL). Mac-Imprint processes have been used for semiconductor patterning with arbitrary and complex 3D micro- and nano-structures. While porous catalytic metal thin-films can be used...

Many countries are experiencing an increase in nitrate and fluoride contamination to their water supply due to the increase in fertilizer runoff, and aging infrastructure. Filter media is anything within a filter that changes that quality of water flowing through it. There and many types of media to choose from depending on the circumstances of one’s...

Background In smaller rural communities, producing potable water often does not involve the highly centralized treatment and distribution infrastructure seen in larger cities. Instead, smaller point-of-use or point-of-entry water treatment solutions provide more cost-effective approaches. With ever-tightening water quality regulations, more focused...
