Crystal defect shown to be key to making hollow nanotubes
Scientists have no problem making a menagerie of nanometer-sized objects - wires, tubes, belts, and even tree-like structures. What they sometimes have been unable to do is explain precisely how those objects form in the vapor and liquid cauldrons in which they are made. Read More
U.S. faces widening information gap on nanotechnology
As the global nanotechnology industry continues to produce cutting-edge consumer products, the scientific community is leaving a key part of the U.S. public behind when sharing knowledge of this new field of science, according to a new study by the University of Wisconsin–Madison and Arizona State University.

Scientists and public differ on views about nanotechnology regulation
When it comes to regulating nanotechnology - a burgeoning global industry with wide-ranging potential applications - a new study led by professors Dietram Scheufele at the University of Wisconsin–Madison and Elizabeth Corley at Arizona State University (ASU) reveals that the views of U.S. nanoscientists differ from those of the general public.

Models present new view of nanoscale friction
To understand friction on a very small scale, a team of University of Wisconsin–Madison engineers had to think big. Read More
Q&A: Professor provides analysis of work on nanotechnology research
Life sciences communication professor Dietram Scheufele provides Wisconsin Week with a more in-depth look at his research on nanotechnology and religion. Read More
For nano, religion in U.S. dictates a wary view
When it comes to the world of the very, very small - nanotechnology - Americans have a big problem: Nano and its capacity to alter the fundamentals of nature, it seems, are failing the moral litmus test of religion. Read More
SEMATECH donates cutting-edge lab equipment to UW–Madison
Students in Mechanical Engineering Professor Roxann Engelstad's lab, sought after in industry for their problem-solving experience, now can graduate even more well-versed in cutting-edge technology. Read More
Spiraling nanotrees offer new twist on growth of nanowires
Since scientists first learned to make nanowires, the tiny wires just a few millionths of a centimeter thick have taken many forms, including nanobelts, nanocoils and nanoflowers. Read More
UW-Madison nano research mixes with art, coffee
In May, 14 striking, larger-than-life photographic prints that are both comfortingly organic and starkly abstract will enable patrons of Mother Fool's Coffeehouse in Madison to visualize a scientific world that's rarely seen outside the laboratory. Read More
Events celebrate nanotechnology
The public can get up close and personal with nanotechnology research during a series of free public nanotechnology events on campus during "Nano Days," Saturday, March 29-Sunday, April 6. Read More
Study: Religion colors Americans’ views of nanotechnology
Addressing scientists in Boston Feb. 15 at the annual meeting of the American Association for the Advancement of Science, Dietram Scheufele, a professor of life sciences communication, presented new survey results that show religion exerts far more influence on public views of technology in the United States than in Europe.

With a jolt, ‘nanonails’ go from repellant to wettable
Sculpting a surface composed of tightly packed nanostructures that resemble tiny nails, University of Wisconsin–Madison engineers and their colleagues from Bell Laboratories have created a material that can repel almost any liquid. Read More
Nanotech’s health, environment impacts worry scientists
The unknown human health and environmental impacts of nanotechnology are a bigger worry for scientists than for the public, according to a new report published Nov. 25 in the journal Nature Nanotechnology. Read More
Wisconsin engineers ready a blueprint for a nanomechanical computer
If efforts now under way by a team of University of Wisconsin–Madison engineers pan out, the age of the nanomechanical computer may be at hand. Read More
Healing chronic wounds through use of nanoscale surfaces
It’s both costly and frustrating when doctors are unable to heal persistent wounds, such as diabetic ulcers or pressure sores in patients with limited mobility. Traditional treatments are often less than satisfactory. But thanks to funding from the Wisconsin Institutes for Discovery seed grant program, UW–Madison researchers have been freed to explore a novel and revolutionary approach to coaxing persistent wounds to heal.

Unique models help teach nanoscience to the blind
At the root of scientific study are observations made with the eyes; yet in nanoscience, our eyes fail us. The smallest object we can see still looms thousands of times larger than a typical nano-sized structure. Even the most powerful microscopes can't peer into the nanoscale directly. Read More
Media effects on public attitudes toward nanotechnology
As the emerging field of nanotechnology enters the public consciousness, mass media play an important role in shaping public attitudes about the new science. But newspapers, the Internet and television do so in significantly different ways, says Dietram Scheufele, a professor of life sciences communication at the University of Wisconsin–Madison. Read More
Nanoscale packaging could aid delivery of cancer-fighting drugs
A University of Wisconsin–Madison pharmacy professor aims to improve the delivery of cancer-fighting drugs by targeting them more selectively to tumors and boosting their solubility in water. Read More
