Contact Resistance and Metallurgical Connections Between Silver Coated Polymer Particles in Isotropic Conductive Adhesives
Pettersen, Sigurd Rolland; Kristiansen, Helge; Nagao, Shijo; Helland, Susanne; njagi, john; Suganuma, Katsuaki; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2016)Recently, there has been an increasing interest in silver thin film coated polymer spheres as conductive fillers in isotropic conductive adhesives (ICAs). Such ICAs yield resistivities similar to conventional silver flake ... -
Deformation and fracture of nano-sized metal-coated polymer particles: A molecular dynamics study
Wu, Jianyang; Nagao, Shijo; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2015)The mechanical behavior of Ni-coated polyethylene (PE) nanoparticles subjected to compression loading is systemically investigated by classical molecular dynamics simulation. Results show that the Ni coatings on PE ... -
Giant Stretchability and Reversibility of Tightly Wound Helical Carbon Nanotubes
Wu, Jianyang; He, Jianying; Odegard, Gregory; Nagao, Shijo; Zheng, Quanshui; Zhang, Zhiliang (Journal article; Peer reviewed, 2013)There is a surging interest in 3D graphitic nanostructures which possess outstanding properties enabling them to be prime candidates for a new generation of nanodevices and energy-absorbing materials.

Investigation of thermal transport in polymer composites with percolating networks of silver thin films by the flash diffusivity method
Pettersen, Sigurd Rolland; Nagao, Shijo; Kristiansen, Helge; Helland, Susanne; Njagi, John; Suganuma, Katsuaki; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2017)The flash diffusivity method, also known as laser flash analysis (LFA), is commonly used to obtain the thermal diffusivity (α) and thermal conductivity (κ) of materials, due to its relative simplicity, rapid measurements, ... -
Loading rate effects on the fracture of Ni/Au nano-coated acrylic particles
He, Jianying; Nagao, Shijo; Kristiansen, Helge; Zhang, Zhiliang (Journal article; Peer reviewed, 2012)Mechanical failure of monodisperse Ni/Au coated acrylic particles has been investigated by individual compression tests using nanoindentation-based technique equipped with a flat diamond punch. We have found that both ... -
Nanohinge-Induced Plasticity of Helical Carbon Nanotubes
Wu, Jianyang; Nagao, Shijo; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2013)Helical carbon nanotubes with intentionally incorporated non‐hexagonal defects have unexpectedly high toughness and plasticity, in addition to the well‐recognized extreme elasticity. The obtained toughness approaches 5000 ... -
Role of Five-fold Twin Boundary on the Enhanced Mechanical Properties of fcc Fe Nanowires
Wu, Jianyang; Nagao, Shijo; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2011)The role of 5-fold twin boundary on the structural and mechanical properties of fcc Fe nanowire under tension is explored by classical molecular dynamics. Twin-stabilized fcc nanowire with various diameters (6~24 nm) are ... -
Size-dependent mechanical behavior of nanoscale polymer particles through coarse-grained molecular dynamics simulation
