Combustion synthesis and Magnetic Characterizations of Mn Substituted Ni–Zn Ferrite Nanoparticles

Mane D.R., Birajdar D.D., Shirsath S.E., Kadam R.H., Shrikrishna Mahavidyalaya, IN

The ferrite samples synthesized by sol–gel auto combustion method using nitrates of respective metal ions. An analysis of X-ray diffraction patterns reveals the formation of single phase cubic spinel structure. Nano size of the particle [...]

Simulation of Virtual Nanoparticle tracking using calculated forces for an Atomic Force Microscope and Optical Tweezers

Dwivedi S.N., Kode S., Ikonomov P.G., Universtiy of Louisiana, Lafayette, US

Nanomanufacturing necessitates manipulation of nanoparticles in order to build functional three dimensional structures. Manipulation of nanoparticles takes place in microenvironments where it is not practical for the user to manually interact with the nanoparticles. So [...]

Prediction Model of Thermal Conductivity for Composite Materials with Nano Particles

Huang C-K, National Taipei University of Technology, TW

In this study, the transport theorem of phonons and electrons is utilized to create a model to predict the thermal conductivity of composite materials with nano particles. By observing or assuming the particle displacement in [...]

The Effects of Nano Particles on the Leidenfrost Phenomenon

Huang C-K, Lin C.K., National Taipei University of Technology, TW

When small amount of liquid mass is deposited on a hot enough solid surface, the liquid may not evaporate rapidly as we expect. Instead, the liquid mass evaporates slowly with a vapor film beneath. This [...]

Condensation and Evaporation of a Nano-sized Particle Moving in a Fluid Environment

Yi M-Y, Lee J.W., Lee M.J., Lee J.W., Lee M.J., Pohang University of Science and Technology, KR

Condensation and evaporation of a low temperature nano-sized argon particle moving in a gas/vapor environment was analyzed using the molecular dynamics simulation. First evaporation temperature for various heating rates was found and successfully compared with [...]

Molecular Dynamics (MD) Simulation on the Collision of a Nano-Sized Particle onto Another Nano-Sized Particle Adhered on a Flat Substrate

Yi M-Y, Lee J.W., Pohang University of Science and Technology, KR

Efficient cleaning of nano-sized particles from substrates becomes more and more crucial in nano fabrication. One promising technique is to bombard the contaminant particles with nano-sized bullet particles, but details of the collision process between [...]

pH-Sensitive Nano-Crystals of Carbonate Apatite Regulate Delivery and Release Kinetics of DNA for Efficient Expression in Mammalian Cells

Chowdhury E.H., Akaike T., Tokyo Institute of Technology, JP

The completion of whole human genome sequencing encourages the development of a powerful gene delivery technology for elucidating structure, regulation and function of genes and proteins in addition to the emerging biomedical applications, such as [...]

A Monte Carlo Study of a Model of Globular Protein Nanoparticles

Pagan D.L., Gracheva M.E., Gunton J.D., Lehigh University, US

We explore the metastable fluid-fluid coexistence curve of the modified Lennard-Jones model of globular proteins of ten Wolde and Frenkel [4]. Using grand canonical Monte Carlo simulations along with mixed-field finitesize scaling and histogram rewighting, [...]
