New technique helps probe performance of organic solar cell materials
Researchers have developed a technique for determining the role that a material's structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers used the technique to determine that materials with a highly organized structure at the nanoscale are not more efficient at creating free electrons than poorly organized structures -- a finding which will guide future research and development efforts.

Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered 'elastic' waves. These waves travel at the surface or through a material without causing any permanent changes to the substance's makeup. Now, engineering researchers at the University of Missouri have developed a material that has the ability to control these waves, creating possible medical, military and commercial applications with the potential to greatly benefit society.

What is the current development in nanomedicine for clinical diagnosis and treatment?
Nanomedicine has been advancing rapidly, particularly in the development of novel nano tools for medicine. This requires multiple nano functionalities for cell targeting, drug storage, optical imaging, and effective treatment. 'Bio-inspired Nanomaterials and Devices' summarizes the most recent developments in nanomaterials, biotechnology, and medical diagnosis and therapy for researchers from diverse fields of chemistry, materials science, physics, engineering, biology, and medicine. Not only does the book touch up on the most fundamental topics, but also deal with critical clinical issues.

MU researcher recognized for contributions to nanomedicine
Gold nanoparticles have been proven useful in a number of medical applications. Scientists are developing nanoparticles to produce pharmaceuticals used in the imaging and diagnosis of diseases such as cancer, arthritis, Parkinson's disease and eye degeneration. For decades, and with funding from the National Institutes of Health, Kattesh Katti, a researcher at the University of Missouri, has been advancing the development of nano-scale molecules, including gold nanoparticles.

Graphene enables all-electrical control of energy flow from light emitters
Scientists from the Institute of Photonic Science, the Massachusetts Institute of Technology, Centre National de la Recherche Scientifique, Consorzio Nazionale Italiano di Struttura della Materia and Graphenea have now demonstrated active, in situ electrical control of the energy flow from erbium ions into photons and plasmons. The experiment was implemented by placing the erbium emitters a few tens of nanometers away from the graphene sheet, whose carrier density is electrically controlled. Partially funded by the EC Graphene Flagship, this study entitled 'Electrical control of optical emitter relaxation pathways enabled by graphene,' has been published in Nature Physics.

Wearable sensor clears path to long-term EKG, EMG monitoring
Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiographyor electromyography. The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.

New laser-patterning technique turns metals into supermaterials
By zapping ordinary metals with femtosecond laser pulses researchers from the University of Rochester in New York have created extraordinary new surfaces that efficiently absorb light, repel water and clean themselves. The multifunctional materials could find use in durable, low maintenance solar collectors and sensors.

New laser for computer chips
Scientists from Forschungszentrum Juelich and the Paul Scherrer Institute in Switzerland in cooperation with international partners have presented the first semiconductor consisting solely of elements of main group IV. As a consequence, the germanium-tin laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.

Gold nanoparticles show promise for early detection of heart attacks
A novel colloidal gold test strip is demonstrating great potential for early detection of certain heart attacks. Researchers are developing the strip to test for cardiac troponin I (cTn-I); its level is several thousand times higher in patients experiencing myochardial infarctions. The new strip uses microplasma-generated gold nanoparticles. Compared to AuNPs produced by traditional chemical methods, the surfaces of thesenanoparticles attract more antibodies, which results in significantly higher detection sensitivity.

Rapid journey through a crystal lattice
How fast do electrons whiz through the atomic layers of a crystal lattice? A team of scientists led by researchers from the Technische Universitat München joined by colleagues from the Max Planck Institute of Quantum Optics, the Ludwig-Maximilians-Universitat Munich and the Technical University of Vienna has now investigated this fundamental question. The researchers measured the time electrons needed to travel through a film consisting of a few layers a of magnesium atoms.
