Nanomanufacturing: introduction

admin — Wed, 06 Jan 2010 01:49:33 +0000

This course will be offered at the University of Michigan during Winter 2010. Nanomanufacturing presents how to make and assemble nanostructures—particularly nanotubes, nanowires, and nanoparticles—into devices and materials ranging from transistors to films, fibers, and structural composites. Emphasis is placed on understanding the unique properties of these building blocks, and how properties scale from the individual elements to bulk material architectures. Scalability is governed by the physical interactions among the structures, and the ability to manipulate and order nanostructures using chemical, mechanical, and electrical means. Our goal is to design new materials and devices using nanostructures, along with elegant and efficient manufacturing processes that that can realize the promise of nanotechnology at commercially-feasible scales. The course culminates in a team project that proposes a novel device or manufacturing process that uses nanostructures, such as a new architecture for a photovoltaic cell or battery electrode, or a self-assembly or printing process.

Lecture notes will be posted in the “Teaching” section at http://www.mechanosynthesis.com.

From Paper: “Observation of the Smallest nanotube with metal square-cross-section” MJ Lagos, F. Sato, J. Bettini, V. Rodrigues, DS Galvão, D. Ugarte Nature Nanotechnology. The study, coordinated by Professor Daniel Ugarte and Professor Douglas Galvão, identified how silver nanowires deform and finally break. During that process, it was observed the spontaneous formation of structures that are hollow and have a square basis, which is the smallest possible with just four atoms in the cross …

Fluorescent glow of carbon nanotubes in live fruit fly

admin — Thu, 20 Sep 2007 11:22:59 +0000

Rice University scientists have captured the first optical images of carbon nanotubes inside a living organism. The research appears in the September 2007 issue of Nano Letters. The researchers fed carbon nanotubes to newly hatched fruit flies. Using a laser, they excited a fluorescent glow from the nanotubes and took pictures of the near-infrared glow with a custom microscope. The researchers hope the technique will be useful in finding new ways to diagnose disease.
