With its ever-escalating pursuit of high efficiency and low cost, the electronics industry prizes understanding specific behaviors of polymers. Now there's help in appreciating the polymer mystique related to the emerging field of molecular conduction in which films of charge-transporting large molecules and polymers are used within electronic devices.
New data processing protocol enables feature-based recognition of Surface-enhanced Raman spectra for intracellular molecule probing of biological targets. It relies on locally detecting the most relevant spectra to retrieve all data independently through indexing.
Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, high-speed circuits and displays, according to Penn State researchers.
Physicists of the University of Hamburg, Germany, managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make them promising candidates for future data storage devices.
Chemists at Oregon State University have identified a compound that could significantly reduce the cost and potentially enable the mass commercial production of silicon nanostructures - materials that have huge potential in everything from electronics to biomedicine and energy storage.
One promising area in the fight against cancer is the use of nanotechnology. The EU-funded NAMDIATREAM ('Nanotechnological Toolkits for Multi-Modal Disease Diagnostics and Treatment Monitoring') aims to contribute by using nanotechnology-based techniques to help in early detection.
Tessellation patterns that have fascinated mathematicians since Johannes Kepler worked out their systematics 400 years ago - and that more recently have caught the eye of both artists and crystallographers - can now be seen in the laboratory. They first took shape on a surface more perfectly two-dimensional than any sheet of writing paper, a single layer of atoms and molecules atop an atomically smooth substrate. Physicists coaxed these so-called Kepler tilings 'onto the page' through guided self-assembly of nanostructures.
A new paper highlights a new technique in which small amounts of a sample can be studied while being hot and squeezed within an electron microscope. Use of such a microscopy method permits determination of details down to the scale of a few atoms, including the detection of unexpected atom types or atoms in unexpected places, as within a mineral.
Christina Shultz, Royal Institute of Technology, Sweden and Virginie Bigand, Grenoble INP Pagora, France, and Assya Boujemaoui, KTH Royal Institute of Technology, Sweden, were named winners of the student poster competition at the 2013 TAPPI International Conference on Nanotechnology for Renewable Materials.
As Paul Youngman, professor of German at Washington and Lee University, and student researchers Matthew Bittner and Curtis Correll learned this summer, your perception of nanotechnology may depend on where you live.
At Arizona State University's Biodesign Institute, Nongjian (NJ) Tao has been designing advanced microscopy methods with the ambitious aim of capturing molecular-scale phenomena in living systems. The new techniques, which combine multiple imaging modalities, are poised to revolutionize the study of biology and the development of new drugs.
