Extremely high thermal conductivity anisotropy of double-walled carbon nanotubes

AIP Advances, 2017
Based on molecular dynamics simulations, we reveal that double-walled carbon nanotubes can possess an extremely high anisotropy ratio of radial to axial thermal conductivities. The mechanism is basically the same as that for the high thermal conductivity

A Double‐walled Noncovalent Carbon Nanotube by Columnar Packing of Nanotube Fragments

Angewandte Chemie International Edition
Abstract Herein, we report the synthesis of double‐walled noncovalent carbon nanotubes (CNTs) through host–guest complexation of nanotube fragments and tube‐forming crystal engineering. As the smallest fragment of double‐walled CNTs, a host–guest complex of perfluorocycloparaphenylene (PFCPP) and carbon nanobelt ...

Silk Fibroin Nanofiber–Immobilized Horseradish Peroxidase Enables Continuous Preparation of Injectable Hydrogels With Negligible Residual Enzyme for Drug Delivery

Advanced Materials Technologies, EarlyView.
Overcoming the immunogenicity challenges of enzyme‐mediated crosslinking, a flow‐through reactor utilizing SFNF‐HRP enables the continuous production of injectable hydrogels. This continuous platform ensures homogeneous crosslinking while minimizing residual HRP in the resulting hydrogels.

Binding of pulmonary surfactant proteins to carbon nanotubes; potential for damage to lung immune defense mechanisms [PDF]

, 2007
Potential pulmonary toxicity of carbon nanotubes is a research area that has received considerable attention. Surfactant proteins A and D (SP-A and SP-D) are collectin proteins that are secreted by airway epithelial cells in the lung.

Defect-related hysteresis in nanotube-based nano-electromechanical systems

Nanoscale Research Letters, 2011
The electronic properties of multi-walled carbon nanotubes (MWCNTs) depend on the positions of their walls with respect to neighboring shells. This fact can enable several applications of MWCNTs as nano-electromechanical systems (NEMS).

Chemorheological behaviour of double-walled carbon nanotube-epoxy nanocomposites

Composites Science and Technology, 2008
Abstract In this work, we propose a chemorheological study of an epoxy resin cured with carboxy-double-walled carbon nanotubes (C-DWNTs) reacted with N-methyldiethanolamine (MDEA). The results showed that 1 wt.% C-DWNTs speed up the cure process of more than 40 min. The NMR analysis suggests that a possible explanation of these findings is due to the

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in
