Researchers have developed a coating technique that they plan to use to protect tur- bine engine and waste incinerator components against heat and oxidation. A topcoat from micro-scaled hollow aluminium oxide spheres provides heat insulation, in the lab, already proved more economical than conventional techniques.
Researchers at Sandia National Laboratories have received a $1.2 million award to develop a technique that they believe will significantly improve the efficiencies of photovoltaic materials and help make solar electricity cost-competitive with other sources of energy.
Researchers report on the in-situ self-assembly of vine-tree-like nanostructure using carbon nanotubes as the building blocks by chemical vapor deposition. This work also provides a general biomimetic strategy toward the design of hierarchical nanomaterials with extraordinary electron pathways as well as tunable surface/interface that can be used in areas of catalysis, separation, and energy conversion and storage.
Wissenschaftler haben eine neue Ansteuerung für Rastertunnelmikroskope entwickelt, die es ihnen ermöglicht, einzelne grosse Molekuele interaktiv mit der Hand zu verschieben. Bisher waren nur simple, starr programmierte Bewegungen moeglich.
Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest possible coupling of only two photons - an important achievement for quantum optics.
How can two clumps of matter pass through each other without sharing space? Physicists have documented a strange disappearing act by colliding Bose Einstein condensates that appear to keep their distance even as they pass through one another.
A new system, developed by researchers at Rockefeller University and their collaborators, promises to make nanobodies - antibodies' tiny cousins - dramatically more accessible for all kinds of research.
MIT has established a formal relationship with Tecnologico de Monterrey, one of Latin America's largest universities, to bring students and faculty from Mexico to Cambridge for fellowships, internships, and research stays in MIT labs and centers. The agreement will initially focus on research at the frontier of nanoscience and nanotechnology.
New research has unlocked the secrets of efficiency in nanomaterials, that is, materials with very tiny particles, which will improve the future development of chemical sensors used in chemical and engineering industries.
The 'Swiss cheese' structure is characteristic of many polymer membranes and is now modified by introducing iron within the polymer. Using an electric signal or a chemical reaction, the pore size can be adjusted. The key to this is controlled adding or extracting of electrons to and from iron.
