A team of researchers from Greece and Spain have managed to synthesize silver nanoparticles, which are of great interest thanks to their application in biotechnology, by using strawberry tree leaf extract. The new technology is ecological, simple, cheap and very fast.
Cornell researchers have developed a new method of generating terahertz signals on an inexpensive silicon chip, offering possible applications in medical imaging, security scanning and wireless data transfer.
Sixteen middle-school students received a unique firsthand look at the exciting world of nanotechnology when they attended Summer NanoCamp at the College of Nanoscale Science and Engineering (CNSE) of the University at Albany on July 10, part of a collaboration between CNSE and the Children's Museum of Science and Technology (CMOST).
Researchers have provided the first atomic-scale insights into the ferroelectric properties of nanocrystals. This information will be critical for development of the next generation of nonvolatile data storage devices.
Researchers have developed an entirely new logic circuit family based on magnetic semiconductor devices. The advance could lead to logic circuits up to 1 million times more power-efficient than today's.
The Nanotechnology Signature Initiative (NSI) Nanotechnology for Sensors and Sensors for Nanotechnology: Improving and Protecting Health, Safety, and the Environment is the fifth NSI to be launched by agencies of the National Nanotechnology Initiative (NNI).
Researchers in Thailand have developed an electronic nose (NanoNose) to help local food industry in areas related to standardizing smell, which is one of the key sensory perceptions for the food industry.
Researchers from the Biomaterial Research Department of Isfahan University of Technology reported the fabrication of a scaffold comprising of a polymer-bioceramic nanocomposite with potential applications as bone replacements and tooth substitutes, in particular.
Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us - this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this 'triboelectric' generator could provide alternating current (AC) from activities such as walking.
A computer model from Rice University shows that long nanotubes bend and snap like twigs when blasted with ultrasonic energy. The research finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.
