Durable Polymeric Antimicrobial Coating for Orthopedics
External fixation is a well-established orthopedic practice in which fractured bones or fusion sites are immobilized for healing by placing wires and/or pins into the bone on either side. Unfortunately, both superficial and deep tissue infections are prevalent with the use of external fixators, particularly Staphylococcal infections. The economic burden...

Novel Solution for Selective Adsorption and Release of Gases Within Porous Materials
The potential for nanoporous materials, such as metal organic frameworks (MOFs), to be used effectively for energy storage and gas capture has been hindered by their relatively weak adsorption of gases. The primary approach for weak adsorption has been to develop metal centers that are more active. Such an approach often leads to complex synthesis procedures...

Multifunctional Ionic liquids for Surface Modification of Dental Implants
Titanium dental implants are known for their high success rates and adequate osseointegration in vivo. However, with an increasing number of implants used, higher incidence of failures has been reported. These failures have been associated with microbial colonization, peri-implant inflammation, corrosion, implant design, overload, as well as a combination...
