In tests, perovskite-based cells made with the same chemical found in coffee maintained their power conversion efficiency for several weeks longer than those without it.
The findings answer questions that have been sought ever since 2005, when two Australian scientists won a Nobel Prize for their discovery of H. pylori and its role in gastric conditions.
Energy created by the movement of two materials can be harvested from the surrounding environment and converted to electricity by a triboelectric nanogenerator.
Denis Chetverikov, Yongjie Hu and Aaswath Raman are among 126 early-career scientists and scholars from across the United States and Canada selected to receive fellowships.
The new imaging technique may lead to improved functionality of devices such as personal computers and smartphones.
The research provides the first direct evidence of the proteins moving through PTEX, the protein complex that transports malaria proteins into the red blood cell.
The characters’ extraordinary abilities are pure science fiction. Or are they?
The device, designed by UCLA Engineering researchers, operates across a broad range of light, processes images more quickly and is more sensitive to low levels of light than current models.
“The center will provide CNSI with the cutting-edge technology to help us maintain our leadership in biophotonics research,” said UCLA’s Laurent Bentolila.
Researchers used cryo electron microscopy to obtain the first atomic model of the particle, which is made up of more than 3,000 protein molecules comprising tens of millions of atoms.
The scientists are working on a way to stop heart disease in patients with this severe muscular dystrophy, which affects one in 5,000 male babies in the U.S.
The new technique produces better images than current methods, and it’s easier to implement because it requires fewer measurements and performs computations faster.
The system is made of inexpensive components, including an image sensor chip that costs just a few dollars apiece and is like the ones used in mobile phone cameras.
“The dream is to have an array of hundreds or thousands of qubits all working together to solve a difficult problem,” said graduate student Joshua Schoenfield. “This work is an important step toward realizing that dream.”
A biologically friendly supercapacitor invented by UCLA and University of Connecticut researchers charges using electrolytes from biological fluids like blood serum and urine.
Rankings by the Milken Institute put UCLA No. 1 in the nation when it comes to the number of startup companies launched as a result of campus research, no. 15 overall.
The combined dye/cellphone reader system achieved comparable results to equipment costing tens of thousands of dollars more.
The terahertz part of the spectrum has potential uses in biological sensing and medical imaging and chemical identification.
A UCLA team creates a "smart" mobile tool that may be used to diagnose and treat serious infections and diseases.
Researchers precisely measured the coordinates of more than 23,000 atoms in a technologically important material.
UCLA-led research shows that adding nanoparticles of aluminum oxide allows for more control over manufacturing processes, which could make them more efficient and reliable.
Local high school students learn about the life of a UCLA scientist and practical uses for nanotechnology.
UCLA and Caltech researchers created jagged platinum nanowires that would require only 1/50 as much platinum as used in current smooth-shaped wires.
UCLA researchers note that the next decade shows great promise for things like improving food safety, fighting infections, storing energy and supplying clean energy.
The UCLA professor emeritus, who directed the California NanoSystems Institute at UCLA, was honored with two others for designing and developing molecular machines.
