Improving the performance of carbon nanotube fibers

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)

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.

On route to artificial retinas with microcavity perovskite photoreceptors

Mon, 05/20/2019 - 11:10
Electronic device versions of the human eye's photoreceptors could potentially be used in a wide range of applications from robotic humanoid vision to artificial retina implantation for vision restoration or even vision extension into a wider range of wavelength. Researchers have now demonstrated that high-performance filterless artificial human photoreceptors can be realized by integrating a novel optical metal/dielectric/metal microcavity structure with vacuum-deposited perovskite photoresponse devices. These easy-to-fabricate artificial photosensors mimic the spectral responses of human color cones and rods.

Applications of carbon materials derived from metal-organic frameworks (MOFs)

Mon, 05/20/2019 - 10:55
Directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons, widely used as electrode materials, due to its flexibility and simplicity. These materials present certain drawbacks, though, such as low surface areas, disordered structures, and non-uniform sizes, which will greatly limit their applications. However, researchers found that carbon materials derived from metal-organic frameworks (MOFs) could overcome these limitations. A review summarizes the applications of MOF-derived carbon materials.
