Model clays and the importance of good networking

The ability to predict mesoscale structure based on the various attributes of nanoparticles, particularly particle size, size distribution, aspect ratio, and chemical functionality, is necessary to understand and potentially tailor the physical response of multi-functional materials.  Recently, molecular-scale modeling approaches have indicated that simple estimates of particle shape and local order in a fluid are sufficient to predict various categories of structural order for many convex polyhedral [Damasceno Science 2012; 337 (6093):453-7].  However, these discontinuous nano-scale modeling approaches implicitly assume local constitutive relationships that may introduce considerable error if interfacial interactions or non-local coupling between mechanical fields are present.  Extensive experimental investigations have been attempted, but little detail on the fundamental physics of the nanoparticles is possible because of challenges in achieving reproducible properties of an ensemble of individual nanoparticles.

Nanoscale Phenomena and Applications – A Gentle Introduction

Nanoscale Phenomena and Applications – A Gentle Introduction

Nanoscale phenomena is as nice a place as any to begin a series of non-technical technical articles.  After all, it has all the trimmings of remarkable potential, fertile innovation opportunities, challenges in commercialization, and non-intuitive barriers to entry, each deserving of its own consideration.  You, me, and everything we generally think of as reality exist on the macroscale.  It’s the arena where our senses make sense, where we live our lives and where we can have some intuitive understanding of the world around us.  To put it a bit more technically, it’s the arena where things are continuous.  Included here are 3 relatively short articles on nanoscale phenomena, which will eventually wrap around to the world of nanofibers, electrospinning, and adhesion that all contribute to the nexus that is Akron Ascent.
