Investigation on capillary force of nanoscale water cluster using a Hybrid AFM-MEMS System

Kwon S., Kim B., Jhe W., Seoul National University, KR

The interaction force between surfaces has a major effect on the behavior of the materials, such as nanoparticles, proteins, various bio-molecules, and so on. The phenomenon of stiction influenced by interaction forces impacts the repetitive [...]

Nanostructure of Interfaces and Giant Magnetoresistance of Co/Cu Superlattices

Chuprakov S.A., Verhovsky S.V., Krinitsina T.P., Bannikova N.S., Blinov I.V., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

The structure, the state of interfaces and magnetoresistance of [Co(1.5nm)/Cu(0.9nm)]n superlattices have been studied. The magnetoresistance decreases with the growth of n from 38% for n = 10 to 24% for n = 40. TEM [...]

Renewable Energy Technology Gains by Interfacial Engineering with Carbon Nanomaterials

Vander Wal R.L., The Pennsylvania State University, US

Creating a new paradigm, nanomaterials, when used as interfacial modifiers have the potential to significantly alter the energy landscape, given that these processes occur predominantly at interfaces. The key concept is that the nanomaterials serve [...]

Biomimetic Biphasic Nanocomposite Scaffold for Osteochondral Regeneration

Castro N.J., O’Brien C., Zhang L.G., The George Washington University, US

The current work focused on the development and evaluation of a novel biomimetic biphasic nanocomposite scaffold for osteochondral interfacial tissue engineering. Tissue-specific growth factor-encapsulated nanospheres were manufactured via a wet electrospray technique and incorporated within [...]

Mapping nanomechanical phenomena of graphene nanostructures using force modulation and ultrasonic force microscopy

Kolosov O.V., Kay N.D., Robinson B.J., Rosamond M., Zeze D., Dinelli F., Lancaster University, UK

Whereas graphene electronic properties are extensively studied, mechanical properties of graphene nanostructures are much less experimentally explored even for simple graphene structures. We use a combination of force sensitive scanning probe microscopies that combines low [...]

Interfacial Shear Strengths of Carbon Nanotube Reinforced Polymer Composites

Wernik J.M., Ornwell-Mott B.J.C., Meguid S.A., University of Toronto, CA

This paper expands on the existing literature of CNT polymer interfaces and describes the development of a multiscale computational model used to investigate the interfacial properties of nonbonded CNT polymer systems. Specifically, in this work, [...]

Atomistic-Based Continuum Modeling of the Interfacial Properties of Structural Adhesive Bonds

Wernik J.M., Meguid S.A., Ruda H., University of Toronto, CA

This work is concerned with the multiscale modeling of nano-reinforced structural adhesive bonds (SABs) that are typically used in the transport industry, with the aerospace sector being the prime target. Specifically, it is our objective [...]

An SOA Aware MOSFET Model for Highly Integrated, Analog Mixed-Signal Design Environments

Hall J., Luo Z., Xiao Y., Young A., Connerney D., Fairchild Semiconductor, US

Circuit simulations involving power devices often require additional checks comparing with generic low power applications. The burden lies with the individual designers to ensure that the power transistors are operating well within the Safe Operating [...]

The bijel: a bicontinuous interfacially jammed emulsion gel

White K.A., Herzig E.M., Schofield A.B., Poon W.C.K., Cates M.E., Clegg P.S., University of Edinburgh, UK

The bijel is a new class of functional material comprised of two simple fluids arrested in a bicontinuous configuration. We stabilize the fluid structure using an interfacial layer of silica particles. As with colloid-stabilized emulsions, [...]
