Nematic Liquid Crystal Composite Materials for DC and RF Switching [PDF]

, 2019
Liquid Crystals (LCs) are widely used in display devices, electro-optic modulators, and optical switches. A field-induced electrical conductivity modulation in pure liquid crystals is very low which makes it less preferable for direct current (DC) and ...

Immobilized MWCNT support osteogenic cell culture

Journal of Materials Science: Materials in Medicine, 2013
The broad use of versatile, strong, lightweight multi-walled carbon nanotubes (MWCNT) for use in biomaterial applications is tempered by ongoing debate about their safety. Recent reports suggest that factors such as their diameter and surface coating affect their function and cytotoxicity.

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

Advanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

Functionalization of MWCNTs with atomic nitrogen

Micron, 2009
In this study of the changes induced by exposing MWCNTs to a nitrogen plasma, it was found by HRTEM that the atomic nitrogen exposure does not significantly etch the surface of the carbon nanotube (CNT). Nevertheless, the atomic nitrogen generated by a microwave plasma effectively grafts amine, nitrile, amide, and oxime groups onto the CNT surface, as ...

Low‐Strain Flexible Ink‐Based Sensors Enable Hyperelastic Inflation Perception Via Geometric Patterning for Balloon‐Type Robots

Advanced Robotics Research, EarlyView.
Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.

A radiation-resistant MWCNT/Nafion/MWCNT composite film for humidity perception

e-Polymers
Abstract Humidity is a necessary detection index in the nuclear industry, but the current humidity sensor is unable to resist nuclear radiation. In this work, we develop a radiation-resistant humidity sensor, which is made of multiwalled carbon nanotube (MWCNT)/Nafion/MWCNT composite film.

Autonomous Locomotion of Tensegrity Structure on Low‐Temperature Surfaces

Advanced Robotics Research, EarlyView.
A low‐temperature responsive tensegrity structure (LRTS) is constructed by integrating low‐responsive temperature liquid crystal elastomer (LCE) cables, nonresponsive cables, and stiff rods. The low phase transition temperature of LCE is achieved by introducing a new liquid crystal mesogen.

Experimental study on the mechanical properties of an epoxy-based nanocomposite using polymeric alloying and different nano-reinforcements: nanofiber, nanolayered and nanoparticulate materials

Science and Engineering of Composite Materials, 2015
This study investigated the effect of four different types of reinforcements on the mechanical properties of an epoxy system. The epoxy resin used was diglycidyl ether of bisphenol A (DGEBA) cured by cycloaliphatic polyamine.
