Graphene-oxide filtration membrane for harsh chemical environments

Filtration is being investigated as an alternative to thermal separation methods (such as distillation and evaporation) in many applications because of the potential energy savings, but conventional filtration membranes, such as those used in water desalination, are often not robust…

Nanoengineered catalysts can upcycle polyethylene

Drawing inspiration from the enzymatic breakdown of macromolecules in cellular systems, scientists at Ames Laboratory (Ames, Iowa; www.ameslab.gov) have developed a nanostructured catalyst that can break down high-density polyethylene (HDPE) and other polyolefins into a narrow distribution of diesel- and…

This nanoengineered catalyst converts mixed, impure waste to biodiesel

In an example of a biologically inspired and nano-engineered catalyst, researchers at RMIT University (Melbourne, Australia; www.rmit.edu.au) have developed ceramic catalyst particles with a porous network organized hierarchically, where one chemical reaction takes place within larger pores, while a second…

Tubular sieves for extracting lithium from brines

Researchers from the College of Chemical Engineering, Nanjing Tech University (Nanjing, China; www.njtech.edu.cn) have developed a new strategy for forming lithium ion-sieve membranes to achieve an efficient recovery of lithium ions from brine or seawater. Spinel lithium manganese oxide ion-sieves…
