When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased dramatically providing new insight into this mysterious blinking behavior.
Anticipating forthcoming experiments, a NIST Center for Nanoscale Science and Technology (CNST) team has shown that few layer graphene stacks have favorable transport properties that could enable engineering of novel electronic devices.
Organisms that stick to the lower structures of ships increase fuel consumption and costs of maintenance substantially. Currently, the organisms are killed with toxic biocides, but these chemicals need to be removed to protect our environment. Researchers are trying to develop environmentally friendly anti-biofouling technologies, such as nano-structured surfaces that make organisms fall off when the ships move.
Researchers have developed a blue organic light emitting diode (OLED) with an efficiency that is double that of the maximum theoretical efficiency limit.This paves the way for longer-lasting, more efficient and vivid OLED displays for the consumer market.
Water and ice may not be among the first things that come to mind when you think about single-walled carbon nanotubes, but a Japan-based research team hoping to get a clearer understanding of the phase behavior of confined water in the cylindrical pores of carbon nanotubes zeroed in on confined water's properties and made some surprising discoveries.
InnovaGeek freely offers the opportunity to publish "teasers of technologies and innovations" available worldwide on its website and mobile application. The goal is to increase the technology visibility for free to help innovators to find partners, new customers or new markets or selling patents.
A research team led by Brown University reports some promising results for earlier diagnosis of hepatocellular carcinoma, the most common cancer to strike the liver. More than 500,000 people worldwide, concentrated in sub-Saharan Africa and Southeast Asia, are diagnosed with it yearly. Most of those afflicted die within six months.
University of Minnesota engineering researchers in the College of Science and Engineering have recently discovered a new alloy material that converts heat directly into electricity. This revolutionary energy conversion method is in the early stages of development, but it could have wide-sweeping impact on creating environmentally friendly electricity from waste heat sources.
For nine days this month, 30 graduate students have been learning how to make nano-sized devices. In six three-hour lab sessions, students learned how to operate equipment and perform the processes crucial to fabricating nano-scale devices.
Dutch and Swiss researchers have developed a biomimetic nanopore that offers a sophisticated test and measurement platform for the way proteins enter the nucleus of a cell. This study provides evidence of how a biomimetic nuclear pore can be created to monitor how single proteins move across the pore.
Hessel Castricum from the University of Amsterdam has developed a versatile membrane that is capable of separating gas and liquid mixtures in an energy-efficient manner. The new membrane can probably be employed under industrial conditions on a large scale in the future. This has not been possible until now, because virtually all membranes developed so far are insufficiently stable.
Scientists have developed a programmable sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions programmed into a set of fuel molecules determining its destination.
Scientists have developed a way to transform ordinary sand - a mainstay filter material used to purify drinking water throughout the world - into a "super sand" with five times the filtering capacity of regular sand.
