Atomic force microscopy (AFM) is a highly sensitive form of microscopy that makes it possible to map a surface with near-atomic resolution. Shaw Wei Kok and colleagues from A*STAR's Singapore Institute of Manufacturing Technology have now developed an AFM measurement method that can improve the sensitivity of the technique even further.
Nearly 100 middle-school students from three Capital Region schools experienced the convergence of "Nanotechnology and Nature" during an educational outreach program presented by the College of Nanoscale Science and Engineering (CNSE) of the University at Albany on April 12 at the Albany Pine Bush Preserve Discovery Center.
Fatih Uckun, MD, PhD, head of Translational Research in Leukemia and Lymphoma at the Children's Center for Cancer and Blood Diseases at Children's Hospital Los Angeles, and a research professor of Pediatrics at the Keck School of Medicine of the University of Southern California, has been awarded $1.7 million from the National Cancer Institute (NCI) to support development of a new strategy to overcome the resistance of cancer cells to radiation therapy.
An electrical engineer at the University at Buffalo, who previously demonstrated experimentally the "rainbow trapping effect" -- a phenomenon that could boost optical data storage and communications -- is now working to capture all the colors of the rainbow.
Microscopically tiny ferromagnetic platelets exhibit a phenomenon which could be exploited in the future for particularly stable magnetic data storage: so-called magnetic vortex cores. Five years ago, researchers at the Max Planck Institute for Intelligent Systems found a way to reverse the magnetic field needles despite their stability using only a tiny amount of energy so that their tips pointed in the opposite direction. Such a switching process is necessary to enable the vortex cores to be used in data processing. The Stuttgart scientists have now discovered a new mechanism which makes this switching process at least 20 times faster and confines it to a far smaller region than before.
Elektronenmikroskope nutzen einen fokussierten Elektronenstrahl, um winzige Objekte sichtbar zu machen. Wird das Instrument mit einem Gasinjektionssystem kombiniert, lassen sich Materialproben manipulieren und nanometerfeine Oberflaechenstrukturen darauf "schreiben". Empa-Forschende haben mit Wissenschaftlern der EPFL diese Methode nun genutzt, um Laser zu verbessern.
Solar cells made from organic materials are inexpensive, lightweight and flexible, but their performance lags behind cells that contain silicon or other inorganic materials. Cornell chemist William Dichtel and colleagues have found a way to synthesize ordered organic films that could be a major step toward solving this problem.
An initiative that aims to complement the support provided by the offices of technology transfer is the European Commission-funded project ProNano - Promoting Technology Transfer of Nanosciences, Nanotechnologies, Materials and new Production Technologies. Ten companies from Spain, Germany, the UK, Italy, Denmark and France have joined forces within ProNano, to help 30 research groups develop attractive investment propositions and get in contact with interested investors.
As cells assemble into a doughnut shape and ascend a hydrogel cone, they do work and thereby reveal the total power involved in forming a three-dimensional structure. That measure not only could help tissue engineers understand their living building materials better, but could also add insight to the understanding of natural tissue formation.
A new discovery promises to help physicians identify patients most likely to benefit from breast cancer drug therapies. If the compound, called "Nanobody", proves effective in clinical trials, it would represent a significant advance for breast cancer drug therapy because some drugs are effective only in some people.
