Improving the performance of carbon nanotube fibers

NanoWerk.com - Tue, 05/21/2019 - 10:53
Carbon nanotube (CNT) fiber is an important one-dimensional macroscopic material. The directional assembly of CNTs can help the fiber realize high mechanical, high electrical and high thermal performance. By introducing thermosetting polymer between the carbon nanotube fibers, the cured polymer can overcome the weak van der Waals interaction between the CNTs and further improve the fiber thermal transport. This results in an effective improvement in thermal conductivity and mechanical properties of CNT fibers.

Magnetically propelled MOFBOTs perform microrobotic drug delivery (w/video)

NanoWerk.com - Mon, 05/20/2019 - 19:10
By applying concepts developed in micro- and nanorobotics, researchers demonstrate the controlled motion and delivery of cargo payloads embedded in metal-organic frameworks (MOFs). The helical MOF-based micromachine, propelled by artificial bacterial flagella, can swim and follow complex trajectories in three dimensions under the control of weak rotational magnetic fields. These swimmers are tumor-responsiv and can act as selectively automated and targeted drug delivery platforms.
