Encapsulating antibiotics inside nanofibers, like a mummy inside a sarcophagus, gives them the amazing ability to destroy drug-resistant bacteria so completely that scientists described the remains as mere "ghosts".
Speaking at the 241st National Meeting and Exposition of the American Chemical Society, an international team of scientists today described use of a new technique to see the paintings under the paintings of Rembrandt, Caravaggio, Rubens, and other 17th Century Old Master painters. The report was among almost two dozen studies presented as part of a symposium on chemistry and art titled "Partnerships and New Analytical Methodologies at the Interface of Chemistry and Art."
Scientists in the United States and the United Kingdom have been awarded funding totaling more than $10.3 million to improve the process of biological photosynthesis. The U.S. National Science Foundation (NSF) and the U.K. Biotechnology and Biological Sciences Research Council (BBSRC) collaborated in issuing these jointly funded awards.
Unlike other drugs that target cancer cells from the outside with minimal effect, this 'transport vehicle' carries multiple drugs that spare healthy cells, accumulate in tumor cells and strike cancer-specific molecular targets inside.
Researchers at the Joint Quantum Institute (JQI) and the California Institute of Technology have shown that it may be possible to take a conventional semiconductor and endow it with topological properties without subjecting the material to extreme environmental conditions or fundamentally changing its solid state structure.
After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements - a finger pinch now en route to a pulse beat in the future - to generate electricity.
Researchers have fabricated a superlens from perovskite oxides that are simpler and easier to fabricate than metamaterials, and are ideal for capturing light in the mid-infrared range, which opens the door to highly sensitive biomedical detection and imaging. It is also possible that the superlensing effect can be selectively turned on/off, which would open the door to highly dense data writing and storage.
Environmentally friendly technologies are becoming increasingly important to Switzerland as an economic and research hub. A new study has revealed that Swiss companies in all sectors are investing substantial sums in energy-efficient technologies. What's more, Switzerland would appear to be one of the most innovative countries in the world in this area.
A nanotechnology-based biosensor being developed by Kansas State University researchers may allow early detection of both cancer cells and pathogens, leading to increased food safety and reduced health risks.
What is so fascinating about this method is that the cells are able to attach to special micrometre-sized "handles" on the scaffolds and nowhere else. The direct laser writing method used gives the researchers full control over the formation of cell adhesion sites and shape of the cells, which represents a major progress in the field of biomaterial engineering.
In Experimenten an der Schnittstelle von Halbleiter- und Atomphysik ist es gelungen, einzelne Photonen auf 4% der Lichtgeschwindigkeit abzubremsen. Das ist ein wichtiges Ergebnis, das den Durchbruch bei der Entwicklung von Quantenspeichern fuer optische Datenpulse z.B. in Quantencomputern bedeuten kann.
The growing impact of nanotechnology on society, including the role of nanoscale education, research and development in health care, clean energy, the environment and electronics, is the focus of a "Nano in the Mall" community outreach initiative presented by the College of Nanoscale Science and Engineering (CNSE) of the University at Albany in conjunction with National NanoDays 2011.
Stanford researchers have developed a rechargeable battery that uses freshwater and seawater to create electricity. Aided by nanotechnology, the battery employs the difference in salinity between fresh and saltwater to generate a current. A power station might be built wherever a river flows into the ocean.
