A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, ...
Fluids such as water are Newtonian, and their viscous behavior is well understood. However, many common fluids are "viscoelastic." These fluids, such as those commonly found in cosmetics, soaps and paints, possess a combination ...
Researchers in the University of Minnesota's College of Science and Engineering have measured the twisting force, or torque, generated by light on a silicon chip. Their work holds promise for applications such as miniaturized ...
Polylactic acid, or PLA, is a biodegradable polymer commonly used to make a variety of products from disposable cups to medical implants to drug delivery systems. A team of Brown University researchers has shown that by treating ...
From the coating of electronic or pharmaceutical products to thin plastic films – a new technique developed by TU Wien enables coating processes to be quality controlled in real time.
Ancient records tell us that the intrepid Viking seafarers who discovered Iceland, Greenland and eventually North America navigated using landmarks, birds and whales, and little else. There's little doubt that Viking sailors ...
ETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarization state of light. With this method, doctors around the world ...
Nanomaterials play an essential role in many areas of daily life. There is thus a large interest to gain detailed knowledge about their optical and electronic properties. Conventional microscopes get beyond their limits when ...
As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer ...
(Â鶹ÒùÔº) —University scientists have developed a rapid new technique involving X-ray imaging that allows clear images to be obtained displaying the orientational properties of molecules in solid materials.
