Physicists has published new advances that they say make possible new nanostructures and nanotechnologies with huge potential applications ranging from clean energy and quantum computing advances to new sensor development.
The chemical stew that makes it possible is a mix of copper nitrate, phosphorous acid, hydrogen fluoride and water. When applied to a silicon wafer, the phosphorus acid reduces the copper ions to copper nanoparticles.
Biological aggregation is a critical, yet often overlooked factor in the medical application of nanoparticles. Here scientists systematically characterize the effects of aggregation on both radiofrequency heating and magnetic resonance image (MRI) contrast of magnetic iron oxide nanoparticles, including detailed analysis of the aggregate morphologies based on quasi-fractal descriptions.
In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from tumbling so that its potential for new applications, such as quantum computing, can be harnessed: shine a single laser on a trapped molecule and it instantly cools to the temperature of outer space, stopping the rotation of the molecule.
Researchers have designed a single molecule which can act as a useful building block in nanometer-size circuits. They found that the molecule functions as a resonant tunneling device, an essential component in mobile phones and WiFi.
Researchers have developed a new sensor that can detect and count nanoparticles, at sizes as small as 10 nanometers, one at a time. The researchers say the sensor could potentially detect much smaller particles, viruses and small molecules.
Scientists have been studying the effects of embedding magnetic spins onto the surface of a superconductor. They report that the spins can interact differently than previously thought. This hybrid platform could be useful for quantum simulations of complex spin systems, having the special feature that the interactions may be controllable, something quite unusual for most condensed matter systems.
A new report reviews the potential implications of nanotechnology on the safety and performance of engineering assets and the infrastructure on which modern society relies on, finds that nanotechnology will have a far reaching impact on almost every industry including energy, transportation, manufacturing, medical, computing and telecommunications.
Touchscreens and solar cells rely on special oxide layers. However, errors in the layers' atomic structure impair not only their transparency, but also their conductivity. Using atomic models, researchers have found ways of identifying and removing these errors.
