A novel microfluidic molding process was used to form microscale features of gold nanoparticles on polyimide, glass, and silicon substrates. This technique uses permeation pumping to pattern and concentrate a nanoparticle ink inside microfluidic channels created in a porous polymer template in contact with a substrate. The nanoparticle ink is self-concentrated in the microchannels, resulting in...

@As the impact process is common in the solar system, it is important to understand the impact process of small bodies in order to study the origin and evolution of these bodies and the solar system. The scale of the impact process in the solar system is far larger than we can address in the laboratory directly. Therefore, numerical simulations offer an effective way to study the impact process...

In this video Q&A, we talk to Paul Wicks about the emergence of participant-led research, and discuss how this field may be expected to develop in the near future, particularly with regard to personalized medicine.

An integrated computational approach to microstructural evolution and electrical transport in ceramic gas sensors has been proposed. First, the particle-flow model and the continuum-phase-field method are used to describe the microstructural development during the sintering of a prototype two-dimensional film. Then, the conductivity of the sintering samples is calculated concurrently as the mic...

BaCe0.7Zr0.1Y0.16Zn0.04O3-δ (BCZYZ) ceramic slurry has been prepared with different solid loading and the maximum of predicted as 25 vol.% using Krieger-Dougherty equation. The formulated applied an electrolyte on porous NiO/BCZYZ tubular supports by dip-coating method. Cells sintered at 1500°C for 10h have characterised Scanning Electron Microscopy (SEM) analysis. 30μ thick, very dense layer s...

The fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. Porous nanocrystalline strontium-doped lanthanum manganite La0.8Sr0.2MnO3 (LSM) cathode materials were prepared by mechanochemical route in various grinding times. Carbon black was employed to produce pores. The formation of LSM single phase was studied by X-ray ...

Sintering parameters of the SS316L water atomised inject ion moulded compact has been optimized for its best sintered density. The L9 (3 4 ) Taguchi orthogonal array is used in the experiment while sintering temperature, sintering time, heating rate and coofing rate was selected as factors that influenced the sintered density. The sintering environment was in the vacuum and four replications we...

Pool boiling heat transfer is measured with two individual working fluids on copper surfaces enhanced with sintered copper powder and carbon nanotubes. The working fluids are a segregated hydrofluoroether, HFE-7300, and deionized water. The surfaces considered in the experiments include smooth copper, copper with sintered copper particles, smooth copper with copper-coated carbon nanotubes (CNT)...
