XAS investigation of catalytically relevant metal and metal oxides dispersed in inorganic matrices

Interaction of bi - dispersed particles with contact line in an evaporating colloidal drop Viral

The deposition behavior of an inkjet-printed aqueous colloidal mixture of microand nanoparticles onto a glass substrate with systematically varied wettability has been investigated using fluorescence microscopy. Real-time bottom-view images show that particles inside an evaporating drop rearrange themselves near the drop contact line according to their sizes, where smaller particles tend to dep...

Production of Dispersed Ceramic Nano-Particles in Al Alloy Using Friction Stir Processing

In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...

Thermal conductivity and contact resistance of metal foams

Accurate information on heat transfer and temperature distribution in metal foams is necessary for design and modelling of thermal-hydraulic systems incorporating metal foams. The analysis of heat transfer requires determination of the effective thermal conductivity as well as the thermal contact resistance (TCR) associated with the interface between the metal foam and the adjacent surfaces/lay...

Origin of Contact Resistance at Ferromagnetic Metal-Graphene Interfaces.

Edge contact geometries are thought to yield ultralow contact resistances in most nonferromagnetic metal-graphene interfaces, owing to their large metal-graphene coupling strengths. Here, we examine the contact resistance of edge- versus surface-contacted ferromagnetic metal-graphene interfaces (i.e., nickel- and cobalt-graphene interfaces) using both single-layer and few-layer graphene. Good q...
