Conductive Coatings Eliminate Static Discharge Risk on Aircraft

Christensen G., Lou D., Grablander T., Younes H., Bailey C., Hong H., Novum Nano, US

Electrically insulating aircraft materials and coatings increase the likelihood of dangerous charge buildup due to static electricity accumulation and cannot protect from lightning strikes. An electrically conductive coating that will prevent static charge buildup and [...]

Solid-Liquid Work of Adhesion

Gulec S., Tadmor R., Das R., Liu J., N'guessan H., Shah M., Wasnik P., Yadav S.B., Lamar University, US

Centrifugal Adhesion Balance (CAB) is used for measuring directly solid-liquid work of adhesion by inducing an ever-increasing normal force which pulls on the droplet while keeping zero lateral force until the liquid-solid contact area starts [...]

Nano-JKR Method Eliminates Adhesion Errors in Nanoindentation of Compliant Polymers and Hydrogels

Ebenstein D.M., Bucknell University, US

Although nanoindentation (or instrumented indentation) was originally developed for characterization of hard, stiff materials such as metals and silicon, this tool has recently seen increased use with compliant polymers and hydrogels. One challenge associated with [...]

Numerical Investigation Of Rigid Microparticles Dynamics: Aggregation And Clogging Phenomena In Microfluidics By Discrete Element Method (DEM) And CFD Coupling

Shahzad K., Van Aeken W., Kamyab V.K., Mottaghi M., Kuhn S., KU Leuven, BE

Microfluidics has achieved a positive response in the industrial sector in the last two decades, i.e., due to its minute size plus control over all the chemical and physical properties at various flow rates (Re~1-10) [...]

Adhesion and friction between supported pH sensitive polymeric nanoparticles monolayers

Giraud L., Giasson S., Universty of Montreal, CA

The unique property of polymers responding to external stimuli has made this class of smart materials very promising for various applications. A particular approach that has been widely used over the past decades is the [...]

Nanotribology and Lubrication at Nanoscale: Molecular Dynamics Simulation Studies

Jabbarzadeh A., The University of Sydney, AU

Increasing technological advances to make devices and processes at the nanoscale, have made it necessary to effectively minimize the friction and adhesion of moving mechanical assemblies, such as those in micro- or nano-electromechanical (MEMS/NEMS) devices. [...]

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 [...]
