Semiconductor nanocrystals emit light at wavelengths that can be tuned by particle size and composition, and are more stable to light than organic dyes, so hopes for their applied use are high. When coated with such agents as surfactants and a semiconductor with a wide band gap, these nanocrystals show strong photoluminescence.
A new polarizing microscope has enabled the detection of a retardation (a unit for measuring the strength of birefringence) of ca. 0.2 nm and the visualization of the dynamism of actin filament bundles with a diameter of 20-60 nm inside a neuron without staining.
Mit Nanotechnologie als Wahlpflichtfach fuer Chemisch-technische Assistenten (CTA) hat die Akademie Muenden beim Innovationspreis des Landkreises Goettingen in der Kategorie Handwerk und Dienstleistungen den dritten Platz belegt.
Soon nanotechnology could be applied to the coating of optical glasses: Researchers of the University of Stuttgart's 1st Physical Institute have come to know that coating with metallic nano particles can suppress light reflection almost entirely.
Singapore's Agency for Science, Technology and Research and the French National Research Agency - ANR (Agence Nationale de la Recherche) announced the first bilateral Joint Call for Proposals (JCP) in the areas of Nanotechnology and Information Communication Science and Technologies.
Imagine if treatments for disease could be based not on a patient's diagnosis but instead on the characteristics of their tissue. By identifying and decoding the cryptic messages hidden deep inside the human proteome, scientists and physicians who study personalized medicine are seeking more effective treatments and disease management for patients.
The biotechnology program at the Harvard Extension School continues to find itself at the leading edge of science education, this year offering several new courses and a new master's concentration in the hot topic area of bioengineering and nanotechnologies.
The molecule 'beryllium dimer' has mystified chemists for many years. Recent measurements have helped scientists identify 11 vibrational levels, and now a US-Czech team of researchers sheds light on a 12th level.
The new homepage of the Laboratory for Attosecond Physics at Max Planck Institute of Quantum Optics and Ludwig Maximilian's University of Munich gives an insight into their research on ultrafast processes in nature.
