Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip.
In a conventional sewage works, nanoparticles should really be bound in the sludge and should not represent a major problem in the aqueous effluent. This is not true, however, as shown by a new study of the ceramic model material cerium dioxide. An astonishing amount was able to leave an experimental sewage works and thus could possibly enter bodies of water.
Research aimed at quickly detecting contamination in food, water and soil and improving early childhood learning for children with mathematical and reading difficulties are two of the 10 projects at The University of Wes...
Smaller and faster are two goals in today's electronics market and an article in an international trade publication shows how North Dakota State University researchers, Fargo, design and build such electronics packages.
Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "p...
Julich scientists have succeeded in precisely measuring atomic spacings down to a few picometres using new methods in ultrahigh-resolution electron microscopy. This makes it possible to find out decisive parameters determining the physical properties of materials directly on an atomic level in a microscope. Knut Urban from Forschungszentrum Julich, a member of the Helmholtz Association, reports on this in the latest issue (25 July) of the scientific high-impact journal Science.
Although order is pleasing to the eye, it can quickly become boring. In Islamic architecture therefore, decoration often follows a strict yet aperiodic pattern. Similar structures also form in certain materials, called quasicrystals. Physicists from the University of Stuttgart and the Max Planck Institute of Metals Research have succeeded in trapping a monolayer of colloidal particles, tiny plastic spheres, in a laser lattice with an aperiodic structure.
Once limited to the electronics industry, semiconductor material may hold the key to improving early detection of prostate cancer among African-American men.
Nanotechnology using quantum dots (QD) made from semicondu...
A research team led by Dr Oleg Gang at the Brookhaven Center for Functional Nanomaterials (CFN) in New York is using the Zetasizer Nano particle characterization system from Malvern Instruments in ground-breaking work that has demonstrated successful DNA-guided formation of ordered 3-D crystalline structures.
Recent progress in dye-sensitized solar cells (DSCs) research and development, which use innovative light-harvesting dye (the "sensitizer") to improve the optical absorption coefficient of the stained nanostructured electrodes, might color our dimming future energy security with a tint of rose, despite the looming depletion of fossil fuels. Costing only 10~20% as its silicon counterparts, the new devices might make it affordable for much more people to utilize solar energy, a handy renewable energy source.
