We've previously heard about wound dressings that kill bacteria,
but now researchers at Australia's Swinburne University of Technology are
taking a different approach. They're creating a dressing material that
attracts bacteria out from within the wound, so that the material and
the microbes can then just be pulled off and discarded.
Last year, StoreDot made news with its rapid-charging smartphone battery that the Israeli startup claimed could be fully recharged in just 30 seconds, while hinting the technology could be scaled up for fast-charging electric vehicles (EVs). After completing a round of funding for a new EV business unit, StoreDot might just be able to deliver on its vision of EVs that can receive a full charge in just five minutes.
electronics miniaturization heads towards a theoretical physical limit in the
tens of nanometers, new methods of manufacturing are required to produce
transistors, diodes, and other fundamental electronic components. In this vein, a new range of molecule-sized
devices have been created in the laboratory, though with varying results in
terms of efficiency and practicality. Now a group of researchers from Berkeley
Lab and Columbia University claims to have created the highest-performing,
single-molecule diode ever made, which is said to be 50 times better in
performance and efficiency than anything previously produced.
Amplifying light a few hundred times with magnifying lenses is easy.
Amplifying light by altering the resonant properties of light itself is a much
more difficult proposition. However, if recent research by engineers at the
University of Wisconsin-Madison engineers is anything to go by, the effort is
well worth it: They claim to have constructed a nanoscale device that can emit
light as powerfully as an object more than 10,000 times its size.
Nanorobots hold great potential in the field of medicine. This is
largely due to the possibility of highly-targeted delivery of medical
payloads, an outcome that could lessen side effects and negate the need
for invasive procedures. But how these microscopic particles can best
navigate the body's fluids is a huge area of focus for scientists.
Researchers are now reporting a new technique whereby nanorobots are
made to swim swiftly through the fluids like blood to reach their
A foldable, inexpensive paper battery that can generate a small amount of electricity brings a new sense of power to origami, the Japanese art of paper folding. An engineer at Binghamton University in New York has developed a battery that creates power through the process of microbial respiration in a drop of dirty water on paper.
Wood pulp-derived nanocellulose is turning out to be pretty useful
stuff. Previously, we'd heard how it could be used in things like high-strength lightweight composites, oil-absorbing sponges and biodegradable computer chips.
Now, researchers from Sweden and the US have used the material to build
soft-bodied batteries that are more shock- and stress-resistant than
their traditional hard counterparts.
