Influence of multi-walled carbon nanotubes on the hydration products of ordinary Portland cement paste

Cement and Concrete Research, 2020
We elucidate the mechanisms by which multi-walled carbon nanotubes (MWCNTs) influence the microstructure, fracture behavior, and hydration of cement paste.

Effect of diameter of multi-walled carbon nanotubes on mechanical properties and microstructure of the cement-based materials

, 2020
This paper is intended to investigate the effects of multi-walled carbon nanotubes (MWCNTs) with different inner diameters on the mechanical properties (flexural strength and compressive strength) and microstructures of cement-based materials.

Polystyrene grafted multi-walled carbon nanotubes

Chemical Communications, 2002
Oxidised, multi-walled, carbon nanotubes can be grafted with polystyrene molecules using an situ radical polymerisation reaction, thereby dramatically modifying their solubility and their suitability for nanocomposite applications.

High-performance removal of diazinon pesticide from water using multi-walled carbon nanotubes

Microchemical journal (Print), 2019
Diazinon is one of the most commonly used organophosphorus pesticides in agricultural activities, and its access to groundwater and surface waters damages the animal and plant environments. This study aimed to evaluate the applicability of the adsorption

Purification of Multi-Walled Carbon Nanotubes

Journal of Nanoscience and Nanotechnology, 2008
The discovery of carbon nanotubes (CNTs) has stimulated intensive research to characterize their structure and to determine their physical properties, both by direct measurement and through predictive methods. Many of the fundamental and remarkable properties of CNTs are now well-known, and their exploitation in a wide range of applications forms a ...

Multi‐walled carbon nanotubes plastic actuator

physica status solidi (b), 2009
AbstractCarbon nanotubes (CNTs) have electrical and mechanical properties that make them highly attractive for actuators. They have the ability to deform elastically by several percent, thus storing very large amounts of energy, thanks to their crystalline nature and to their morphology.

Multi-Walled Carbon Nanotube Growth in Multi-Walled Carbon Nanotubes by Chemical Vapor Deposition

Journal of Nanoscience and Nanotechnology, 2015
We report chemical vapor deposition (CVD) growth of a multi-walled carbon nanotube (MWCNT) inside another MWCNTs from a cementite (Fe3C) catalyst nanoparticles. The CNTs have bi or tri-layered core(s)-sheath structure with various crystallinity. The sheath grows first at a lower temperature, and then the catalyst nanoparticle works again to grow the ...

Multi-walled carbon nanotube impedance

2010 IEEE International Conference on Integrated Circuit Design and Technology, 2010
In future technologies, people will confront with traditional Cu interconnect problems and there is a widespread demand for single-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT). One of the most important parts in carbon nanotube interconnects is their impedance. Thus we investigate impedance, especially dc resistance, in multi
