Synergistic π‐π and π‐d Interactions Between Carbon Nanotubes and Coordination Polymers Crafting Core‐Shell Nanostructured Cathode for High‐Performance Sodium‐Organic Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ni‐DHBQ nanosheets are encapsulated around carbon nanotubes, resulting in a core‐shell layered heterostructure that enables high high‐throughput charge transfer. This unique architecture not only enhances electron transport efficiency but also significantly increases the density of redox‐active sites.

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.

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

Nanomechanical imaging of multi-walled carbon nanotubes

MRS Proceedings, 2003
AbstractNanomechanical mapping of individual multi-walled carbon nanotubes (MWNTs) has been undertaken to investigate intra-tube variations of mechanical response. Ultrasonic force microscopy has been used to measure the relative axial and radial variations of contact stiffness of individual MWNTs synthesized using chemical vapor deposition (CVD) and ...
