Trapping Monolayer of Colloidal Particles in a Laser Lattice with Aperiodic Structure

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.

Taking Images of Ice Nanometers Thick Opens Door to New Experiments

Taking images of ice a few nanometers thick as it forms bulk ice was supposed to be impossible. A scanning tunneling microscope (STM) shouldn t work with ice because STMs create images by relying on conducting current, which runs contrary to one of ice's basic properties - insulation.

Nanotechnology Making Solar Energy More Affordable

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.
