Nanoshuttle Wear and Tear: It’s the Mileage, Not the Age

Hess-proteinwear0106cropcopyNatureNanotechnologypaper.jpg

As nanomachine design advances, researchers are moving from wondering if the nanomachine works to how long it will work—an important question as there are so many potential applications, e.g., for medical uses including drug delivery and early diagnosis. Columbia Engineering Professor Henry Hess observed a molecular shuttle powered by kinesin motor proteins and found it to degrade when operating, marking the first time degradation has been studied in detail in an active, autonomous nanomachine.

Carbon Nanotube Finding Could Lead to Flexible Electronics with Longer Battery Life

University of Wisconsin-Madison materials engineers have made a significant leap toward creating higher-performance electronics with improved battery life — and the ability to flex and stretch. Led by materials science Associate Professor Michael Arnold and Professor Padma Gopalan, the team has reported the highest-performing carbon nanotube transistors ever demonstrated. In addition to paving the way for improved consumer electronics, this technology could also have specific uses in industrial and military applications.

Story Tips from the Department of Energy’s Oak Ridge National Laboratory, January 2015

While researchers in ORNL’s buildings group focus on increasing energy efficiency using new foam insulation panels, the nanophase materials sector experiments with catalyst performance, revealing an oxidation discovery that could help reduce vehicle emissions. Additionally, ORNL researchers aim to reduce the size, weight and power for some particle accelerators with development of a new voltage supply. And by using water and nano-sized particles isolated from trees and plants, scientists explore low-cost and nontoxic metal oxides.

Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties—such as position-dependent, tunable bandgaps—that are potentially very useful for next-generation electronic circuitry.
