Very small pores make a big difference in filtering technology

Nanoporous membranes have been shown to be valuable tools for filtering out impurities from water and numerous other applications. However, there's still much work to be done in perfecting their designs. Recently, the lab ...

Acoustic propulsion of nanomachines depends on their orientation

Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, ...

Anchoring single atoms for catalysis

There is a dictum to "never change a running system." New methods can however be far superior to older ones. While to date chemical reactions are mainly accelerated by catalytic materials that comprise several hundreds of ...

Scientists thread rows of metal atoms into nanofiber bundles

Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers. By steeping the bundles in indium gas, rows ...

Improving crystal engineering with DNA

Northwestern investigators have demonstrated that fine-tuning DNA interaction strength can improve colloidal crystal engineering to enhance their use in creating an array of functional nanomaterials, according to a recent ...
