In an important step towards more practical quantum information processing, researchers from the National Institute of Standards and Technology (NIST), the University of California, San Diego; and the Politecnico di Milano in Milan, Italy, have demonstrated the first heralded single photon source made from silicon.
For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs - usually without a trace.
In the first side-by-side tests of a half-dozen palladium- and iron-based catalysts for cleaning up the carcinogen TCE, Rice University scientists have found that palladium destroys TCE far faster than iron - up to a billion times faster in some cases.
The IDTechEx Printed Electronics Asia event in Tokyo, Japan on October 2-3, features the latest achievements, roadmaps and insight on OLEDs - whether or not they are printed. The leading Asian display and material companies reveal their progress while European and American companies cover their latest breakthroughs in materials.
Researchers from North Carolina State University have developed a new technique for controlling the crystalline structure of titanium dioxide at room temperature. The development should make titanium dioxide more efficient in a range of applications, including photovoltaic cells, hydrogen production, antimicrobial coatings, smart sensors and optical communication technologies.
Angel Rubio is the leader of the research group with the highest number of citations in Spain among those engaged in Materials Physics and Nanoscience. He is in charge of the Nano-bio Spectroscopy Group of the UPV/EHU and the vice-president of science for the European Theoretical Spectroscopy Facility (ETSF).
The properties of nanomaterials often differ in novel ways from those of the bulk material of the same substances. European researchers investigated a completely new class of such materials that could be important for magnetic memory devices.
Researchers used a novel computational method to demonstrate that the properties of what had previously been thought to be only a hypothetical structure of a superhard form of carbon called "M-carbon" - constructed in 2006 - matched perfectly the experimental data on "superhard graphite".
Taking their inspiration from cellular membranes, researchers have developed the first dynamic membrane for water filtration which, depending on the water pressure, can adjust the size of its pores in an autonomous manner.
The world's smallest three-dimensional optical cavities with the potential to generate the world's most intense nanolaser beams have been created. In addition to nanolasers, these unique optical cavities with their extraordinary electromagnetic properties should be applicable to a broad range of other technologies, including LEDs, optical sensing, nonlinear optics, quantum optics and photonic integrated circuits.
Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells.
