Synthesis of Au@Pt Core-Shell Nanoparticles with High Electro-catalytic Activity of Methanol Oxidation by Photochemical Seeding Growth

International Journal of Electrochemical Science, 2013
Au@Pt core-shell nanoparticles were synthesized by photochemical seeding growth method in PEG-acetone system, in which the thickness of Pt shell could be controlled by changing the molar ratio of Au seed to Pt(IV).

Hyperpolarized Long-T1 Silicon Nanoparticles for Magnetic Resonance Imaging [PDF]

, 2009
Silicon nanoparticles are experimentally investigated as a potential hyperpolarized, targetable MRI imaging agent. Nuclear T_1 times at room temperature for a variety of Si nanoparticles are found to be remarkably long (10^2 to 10^4 s) - roughly ...

Fabrication of Hollow AlAu2 Nanoparticles by Solid State Dewetting and Oxidation of Al on Sapphire Substrate

, 2018
The Al-Au binary diffusion couple is a classic example of the system exhibiting Kirkendall voiding during interdiffusion. We demonstrate that this effect, which is a major reason for failures of the wire bonds in microelectronics, can be utilized for ...

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...
