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 ...
SMART: Facial recognition for molecular structures
Paradigm shift in interpretation of NMR spectra
09-Nov-2017
An interdisciplinary team of researchers at the University of California San Diego has developed a method to identify the molecular structures of natural products that is significantly faster and more accurate than existing methods. The method works like facial recognition for molecular ...
Stretchable biofuel cells extract energy from sweat to power wearable devices
25-Aug-2017
A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used ...
Primordial black holes may have helped to forge heavy elements
08-Aug-2017
Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. As the late Carl Sagan once put it: "The nitrogen in our DNA, the calcium in our teeth, the iron in ...
Printed, flexible and rechargeable battery can power wearable sensors
29-May-2017
Nanoengineers at the University of California San Diego have developed the first printed battery that is flexible, stretchable and rechargeable. The zinc batteries could be used to power everything from wearable sensors to solar cells and other kinds of electronics. The researchers made the ...
Bacteria in marine sponge produce toxic flame retardant-like compounds
16-May-2017
A Scripps Institution of Oceanography at the University of California San Diego-led research team discovered for the first time that a common marine sponge hosts bacteria that specialize in the production of toxic compounds nearly identical to man-made fire retardants. The new findings put the ...
