Getting a feel for the nano world

New models help introduce the blind to careers in nanoscale science and engineering

When it comes to research at the nanoscale, vision is not necessarily an advantage. The subjects are so small, no one can see them. To encourage people with visual impairments to pursue fields in nanotechnology, educators have developed a way to craft accurate, detailed and touch-friendly models of nanoscale objects like carbon nanofibers, allowing the students to "see" those objects for the first time.




While students have learned from abstract models of chemical structures for decades, the new technique creates 3-D versions of objects as they actually are.

Developed by educators at the University of Wisconsin-Madison (UW-Madison), the models are about the size of a textbook and are formed using rapid prototyping, a process that "prints" 3-D objects. Each model is a scaled-up replica of tweaked data from a scanning electron microscope. The creators hope they will soon be able to apply the same process to data from other instruments, including the patterns of atoms revealed by atomic force microscopes.

Small optical force can budge nanoscale objects
With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported.

Small nanoparticles bring big improvement to medical imaging
If you're watching the complex processes in a living cell, it is easy to miss something important-especially if you are watching changes that take a long time to unfold and require high-spatial-resolution imaging.

Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident.

Magnetic nanoparticles to simultaneously diagnose, monitor and treat
Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade.

Breakthrough in industrial-scale nanotube processing
Rice University scientists today unveiled a method for the industrial-scale processing of pure carbon-nanotube fibers that could lead to revolutionary advances in materials science, power distribution and nanoelectronics.

Nanoscale: Visualizing an Invisible World

Nanoscale: Visualizing an Invisible World
by Kenneth S. Deffeyes (Author), Stephen E. Deffeyes (Author)

The world is made up of structures too small to see with the naked eye, too small to see even with an electron microscope. Einstein established the reality of atoms and molecules in the early 1900s. How can we see a world measured in fractions of nanometers? (Most atoms are less than one nanometer, less than one-billionth of a meter, in diameter.) This beautiful and fascinating book gives us a tour of the invisible nanoscale world. It offers many vivid color illustrations of atomic structures, each accompanied by a short, engagingly written essay. The structures advance from the simple (air, ice) to the complex (supercapacitor, rare earth magnet). Each subject was chosen not in search of comprehensiveness but because it illustrates how atomic structure creates a property (such as...

No Small Matter: Science on the Nanoscale

No Small Matter: Science on the Nanoscale
by Felice C. Frankel (Author), George M. Whitesides (Author)

A small revolution is remaking the world. The only problem is, we can’t see it. This book uses dazzling images and evocative descriptions to reveal the virtually invisible realities and possibilities of nanoscience. An introduction to the science and technology of small things, No Small Matter explains science on the nanoscale.

Authors Felice C. Frankel and George M. Whitesides offer an overview of recent scientific advances that have given us our ever-shrinking microtechnology—for instance, an information processor connected by wires only 1,000 atoms wide. They describe the new methods used to study nanostructures, suggest ways of understanding their often bizarre behavior, and outline their uses in technology. This book explains the various means of making...

Electrical Transport in Nanoscale Systems

Electrical Transport in Nanoscale Systems
by Massimiliano Di Ventra (Author)

This graduate textbook provides an in-depth description of the transport phenomena relevant to systems of nanoscale dimensions. The different theoretical approaches are critically discussed, with emphasis on their basic assumptions and approximations. The book also covers information content in the measurement of currents, the role of initial conditions in establishing a steady state, and the modern use of density-functional theory. Topics are introduced by simple physical arguments, with particular attention to the non-equilibrium statistical nature of electrical conduction, and followed by a detailed formal derivation. This textbook is ideal for graduate students in physics, chemistry, and electrical engineering.
