Scientists have considered a specific DNA filament model and examined its behavior within a nano-channel. They observed that by varying the channel's width it is possible to drastically change the quantity and complexity of the knots formed by the DNA.
A quantum computer doesn't need to be a single large device but could be built from a network of small parts, new research from the University of Bristol has demonstrated. As a result, building such a computer would be easier to achieve.
Forschende der Universität Basel und der Fachhochschule Nordwestschweiz (FHNW) haben eine Methode entwickelt, um mithilfe eines neuartigen nanotechnologischen Verfahrens Viren zu erkennen. Das Verfahren könnte zur Herstellung von Viren, aber auch zur Diagnostik und Therapie verschiedener Krankheiten eingesetzt werden.
Researchers have developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened.
A bright blue pigment used 5,000 years ago is giving modern scientists clues toward the development of new nanomaterials with potential uses in state-of-the-art medical imaging devices, remote controls for televisions, security inks and other technology.
Electrodes operated into the brain are today used in research and to treat diseases such as Parkinson's. However, their use has been limited by their size. At Lund University in Sweden, researchers have, for the first time, succeeded in implanting an ultrathin nanowire-based electrode and capturing signals from the nerve cells in the brain of a laboratory animal.
UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors - devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom-thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.
Using chemical imaging techniques, scientists at Pacific Northwest National Laboratory proved for the first time that titanium dioxide's surface defects shelter chemicals from decays caused by ultra-violet light. The defects are tiny gaps created when oxygen atoms are missing from the surface of this popular catalyst.
A Johns Hopkins engineer who is designing cancer-fighting nano-size structures that could assemble themselves and deliver treatment to diseased tissue has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation.
Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are now presenting the missing piece.
