nanoHUB.org is designed to be a resource to the entire nanotechnology discovery and learning community.
In this presentation, I will highlight a relatively understudied electromechanical coupling called flexoelectricity that appears to have implications in topics ranging from biophysics to the design of next-generation soft multifunctional materials. Specifically, I will argue, through...
This presentation will highlight the recent work of Dr. Schaefer’s lab on a number of energy systems, which are unified through the application of rigorous thermofluid modeling, both on the small scale and at the systems level. An overview will be presented of the lattice Boltzmann method...
The Laser Thermal Laboratory has conducted work on the fundamental study of laser material interactions across length and me scales in the context of laser microprocessing and maskless nanomanufacturing. Understanding of the associated energy transport phenomena has opened the way to...
In this presentation, we will motivate the importance of doing research with integrity. We will discuss what it takes to make ethical decisions and work through several case studies that exemplify the types of issues that may arise.
In this talk, we will explore some recent results in observations of structure and dynamics in a variety of systems ranging from polymer dynamics in ambient conditions, 3D atomic resolution mapping of the structure of the solid-liquid interface, defect dynamics in crystal lattice and biologically...
The vibration behavior of a resonant system can be modified dramatically by the additional of one or more relatively small resonant substructures. The simplest example is a tuned mass damper, in which a single small element is added with a resonant frequency tuned to match that of the primary system. We consider the case of multiple elements added with prescribed distributions of properties (mass, stiffness, damping) to achieve a variety of effects in frequency or time domain. ...
Micro/nanoscale thermal radiation has attracted great attention due to the promising applications in energy harvesting, nanomanufacturing, thermal control and management, and high-resolution thermal mapping. In the near-field, radiative heat transfer between closely spaced objects can be...
In this seminar, recent developments in the design of self-folding origami will be presented. A design framework consisting of target shape identification and rigid foldability analysis, modeling and optimization, and prototype fabrication will be described. Particular focus will be on finite element and rigid body dynamic modeling and optimization approaches for single and multi-field actuation of self-folding origami structures.
Here I will discuss how we are using new fabrication strategies (three-dimensional laser engraving, 3D printing) to create architectured / bio-inspired materials with highly unusual combinations of properties: High stiffness and high toughness in nacre-like glasses and ceramics, hardness and flexural compliance in fish scale-inspired protective skins.
