A new approach analyzing car paint based on the medical imaging technique optical coherence tomography (OCT) provides the car industry with a practical way to automatically analyze these metal flakes, which until now have been difficult to image, in order to improve the efficiency of the automotive finishing process.
Robotics researchers have found a way for autonomous underwater vehicles to navigate strong currents with greater energy efficiency, which means the AUVs can gather data longer and better.
Researchers from the UAB, in collaboration with the ICN2, have developed a nanoporous material based on a copper and nickel alloy, with a structure similar to that of a sponge with pores measuring the size of a millionth of a millimeter, which allows handling and storing information using very little energy. These nanosponges could be the base of new magnetic memories for computers and mobile phones with greater energy efficiency than those currently existing.
Information technologies of the future will likely use electron spin -- rather than electron charge -- to carry information. But first, scientists need to better understand how to control spin and learn to build the spin equivalent of electronic components and tools. Now, Harvard researchers have developed a technique to control and measure spin voltage, known as spin chemical potential. The technique, which uses atomic-sized defects in diamonds is essentially a nanoscale spin multimeter that allows measurements in chip-scale devices.
In a nanoscale photodetector that combines a unique fabrication method and light-trapping structures, a team of engineers from the University of Wisconsin-Madison and the University at Buffalo has overcome obstacles to increasing performance in optoelectronic devices -- like camera sensors or solar cells -- without adding bulk.
Scientists have created unique atomic-scale ID's based on the irregularities found in 2-D materials like graphene. On an atomic scale, quantum physics amplifies these irregularities, making it possible to 'fingerprint' them in simple electronic devices and optical tags. For the first time, the team will be showcasing this new technology via a smartphone app which can read whether a product is real or fake, and enable people to check the authenticity of a product through their smartphones.
Quantum technology is seen as an important future-oriented technology: smaller, faster and with higher performance than conventional electronics. However, exploiting quantum effects is difficult because nature's smallest building blocks have properties quite distinct from those we know from our everyday world. An international team of researchers has now succeeded in extracting a fault tolerant manipulation of quanta from an effect of classical mechanics.
UW engineers have designed the first battery-free cellphone that can send and receive calls using only a few microwatts of power, which it harvests from ambient radio signals or light. It's a major step forward in moving beyond chargers, cords and dying phones.
System with $150 worth of hardware offers alternative to 3-D scanners that cost 200 times as much.
New method of measurement could lead to cheaper, more accurate sensors.
