Stabilization of colloidal suspensions by means of highly-charged nanoparticles

, 2004
We employ a novel Monte Carlo simulation scheme to elucidate the stabilization of neutral colloidal microspheres by means of highly-charged nanoparticles [V. Tohver et al., Proc. Natl. Acad. Sci. U.S.A. 98, 8950 (2001)].

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

Advanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Microscopic theory of single-electron tunneling through molecular-assembled metallic nanoparticles

, 2003
We present a microscopic theory of single-electron tunneling through metallic nanoparticles connected to the electrodes through molecular bridges. It combines the theory of electron transport through molecular junctions with the description of the ...

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Facile Synthesis Toward Surface Decorated Ir1Ox@Pd35 with Low Iridium Content for Highly Efficient and Durable Proton Exchange Membrane Water Electrolyzer

ChemElectroChem
Herein, we introduce an iridium‐decorated palladium nanocluster (Ir1Ox@Pd35) synthesized via an epoxide‐assisted sol‐gel method. The nanocluster had a unique surface‐decorated structure, as confirmed by transmission electron microscopy (TEM) and ...

Magnetic relaxation in finite two-dimensional nanoparticle ensembles

, 2003
We study the slow phase of thermally activated magnetic relaxation in finite two-dimensional ensembles of dipolar interacting ferromagnetic nanoparticles whose easy axes of magnetization are perpendicular to the distribution plane. We develop a method to

Thermodiffusion in model nanofluids by molecular dynamics simulations

, 2007
In this work, a new algorithm is proposed to compute single particle (infinite dilution) thermodiffusion using Non-Equilibrium Molecular Dynamics simulations through the estimation of the thermophoretic force that applies on a solute particle.
