Speedy single-molecule nanosubs powered by UV light

For some time now, we've been hearing about the attempts by various groups to develop so-called nanosubmarines. Among other things, these microscopic "molecular machines" could conceivably be used for applications such as targeted drug delivery within the human body. Recently, scientists at Houston's Rice University created nanosubs that move at a "breakneck pace" when exposed to ultraviolet light. Read More

World's first "porous liquid" could be used for CO2 sequestration

The Italians have a colorful expression – to make a hole in water – to describe an effort with no hope of succeeding. Researchers at Queen's University Belfast (QUB), however, have seemingly managed the impossible, creating a class of liquids that feature permanent holes at the molecular level. The properties of the new materials are still largely unknown, but what has been gleaned so far suggests they could be used for more convenient carbon capturing or as a molecular sieve to quickly separate different gases.Read More

Nanoscale wrench is just 1.7 nanometers wide

Envision a nanoscale wrench, capable of controlling shapes at the nanoscale level to create customized molecules. That's what Severin Schneebeli, a University of Vermont chemist and his team have developed. The opening on this mini wrench is only 1.7 nanometers, roughly a hundred-thousand-times smaller than the width of human hair.Read More

DARPA's fascinating self-healing body initiative – ElectRx

DARPA's ElectRx project envisions tiny devices, the width of a single nerve strand, that could be injected into the body to monitor certain conditions and then stimulate targeted nerves in response, harnessing the body’s own repair mechanisms to deal with a range of conditions like chronic pain, diabetes, rheumatoid arthritis and certain autoimmune diseases. DARPA sees the potential to create new treatments that automatically and continuously tune themselves to the needs of a specific patient.Read More

StoreDot to scale up nanodot battery tech in pursuit of five minute-charging EVs

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.Read More

World's highest-performance single-molecule diode created

As 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.Read More

Nanoscale device emits light as bright as an object 10,000 times its size

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.Read More
