Overview Synthetic melanins have similar properties as lab-made carbon nanomaterials but are biocompatible and can be prepared sustainably. However, commercial adoption of melanin nanomaterials is hindered by limited size control, poor scale-up, and limited solubility, preventing use in advanced el…

Inorganic membranes have been employed for a variety of gas separation applications, including hydrogen purification and carbon dioxide sequestration. A major limiting factor to the application of inorganic membranes is the frequent occurrence of defects which limits reproducibility, stability, an…

Zeolites are microporous structures with uses such as absorbents and catalysts. For example, in the petrochemical industry for fluid catalytic cracking and hydrocracking, absorbants to trap fission products from nuclear waste, and for domestic uses such as in detergents and cat litter. The materia…

Fuel cells offer a cleaner, more-efficient alternative to gasoline and other fossil fuels, and have the potential to revolutionize the way the nation is powered. Fuel cells operate in a similar fashion to conventional batteries, but fuel cells can be continually supplied with a fresh feed of fuel,…
