Ultrasound device improves charge time and run time in lithium batteries
The device brings lithium metal batteries one step closer to commercial viability
20-Feb-2020
Researchers at the University of California San Diego developed an ultrasound-emitting device that brings lithium metal batteries, or LMBs, one step closer to commercial viability. Although the research team focused on LMBs, the device can be used in any battery, regardless of chemistry. The ...
Machine learning technique speeds up crystal structure determination
04-Feb-2020
Nanoengineers at the University of California San Diego have developed a computer-based method that could make it less labor-intensive to determine the crystal structures of various materials and molecules, including alloys, proteins and pharmaceuticals. The method uses a machine learning ...
A quantum breakthrough brings a technique from astronomy to the nano-scale
Multi-messenger approach allows to probe electronic and magnetic materials at ultra-small length scales
07-Jan-2020
Researchers at Columbia University and University of California, San Diego, have introduced a novel "multi-messenger" approach to quantum physics that signifies a technological leap in how scientists can explore quantum materials. "We have brought a technique from the inter-galactic scale down to ...
Scientists use artificial neural networks to predict new stable materials
20-Sep-2018
Artificial neural networks--algorithms inspired by connections in the brain--have "learned" to perform a variety of tasks, from pedestrian detection in self-driving cars, to analyzing medical images, to translating languages. Now, researchers at the University of California San Diego are training ...
'Building up' stretchable electronics to be as multipurpose as your smartphone
16-Aug-2018
By stacking and connecting layers of stretchable circuits on top of one another, engineers have developed an approach to build soft, pliable "3D stretchable electronics" that can pack a lot of functions while staying thin and small in size. As a proof of concept, a team led by the University of ...
Materials processing tricks enable engineers to create new laser material
20-Jul-2018
By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses--a combination that could potentially yield smaller, more powerful lasers with superior thermal shock ...
A better way to control crystal vibrations
23-May-2018
The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. For ...
Watching atoms move in hybrid perovskite crystals reveals clues to improving solar cells
23-Nov-2017
A team of researchers led by the University of California San Diego has for the first time observed nanoscale changes deep inside hybrid perovskite crystals that could offer new insights into developing low-cost, high-efficiency solar cells. Using X-ray beams and lasers, researchers studied how a ...
