Scientists have shown that certain nanomaterials, such as carbon nanotubes, enter cells tip-first and almost always at a 90-degree angle. The orientation ends up fooling the cell; by taking in the rounded tip first, the cell mistakes the particle for a sphere, rather than a long cylinder. By the time the cell realizes the material is too long to be fully ingested, it's too late.
Researchers from the University of Toronto, King Abdullah University of Science and Technology and Pennsylvania State University have created the most efficient colloidal quantum dot (CQD) solar cell ever.
The National Institutes of Health will collaborate with the Defense Advanced Research Projects Agency (DARPA), and the U.S. Food and Drug Administration to develop a chip to screen for safe and effective drugs far more swiftly and efficiently than current methods, and before they are tested in humans.
The University of Massachusetts Amherst has received a five-year, $20 million grant from the National Science Foundation (NSF) to support a national research center on nanomanufacturing. The grant will fund the university's Center for Hierarchical Manufacturing.
An Italian-British team of scientists has succeeded in drawing superconducting shapes using an X-ray beam. The study shows how being able to create and control tiny superconducting structures could lead to innovative electronic devices.
Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales.
Der Schwerpunkt der durchgefuehrten Literaturauswertungen lag auf der Analyse der Aussagekraft von In-vitro-Gentoxizitaetstests in Relation zur Karzinogenitaet atembarer faserfoermiger und granulaerer Staeube gemaess Epidemiologie und Langzeit-Tierversuchen.
Research by a team from two European universities and SLAC National Accelerator Laboratory shows that attractive forces between other parts of a molecule can make a stretched bond joining two carbon atoms much more stable than expected. This result should lead to improvements in how scientists design new molecules, materials and catalysts.
Masahiro Yoshimura, a world-renowned expert on ceramics and materials science, has been appointed director of National Cheng Kung University's Promotion Center for Global Materials Research (PCGMR), which will be launched on September 23.
A*STAR Institute of Microelectronics and the University of Washington announce that they will join forces to provide shared Silicon Photonics processes as part of the Optoelectronics Systems Integration in Silicon programme (OpSIS). This will help the research and development community significantly reduce the fabrication cost of silicon photonics integrated circuits.
A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.
In a new article published in Nature Nanotechnology, biological engineers and medical scientists at the University of Missouri reveal how their discovery could provide a much earlier warning signal for lung cancer.
A major challenge for nanobusiness is to find a unique selling proposition, out of a diverse range of possible applications. Potential investors need better understanding of nanotech-related business opportunities.
