UCLA researchers and colleagues have designed a first-of-its-kind nanogenerator that can work in remote areas because it provides its own power and does not need batteries. It also acts as a weather station.
The engineers and mathematicians have designed a unique and effective system that could be used to produce clean, fresh water, or to recycle industrial water that would otherwise be wasted.
The donation from alumna Stacey Nicholas create a permanent funding source for WE@UCLA, which was founded in 2017.
Researchers create ultra-lightweight ceramic material that can better withstand extreme temperatures
The aerogel stood up to sudden and extreme temperature spikes between minus 198 degrees Celsius and 900 degrees above zero over just a few seconds.
UCLA researchers already are working with a bicycle manufacturer on prototype frames that would use the alloy.
To help the new system “learn” more like people do, the engineers immersed it in an internet replica of the real world.
Artificial intelligence-based device detects moving parasites in bodily fluid for easier, earlier diagnosis
“The platform is like a motion detector for the microscopic world because of its ability to lock onto any moving objects in a fluid sample,” said Yibo Zhang, a UCLA doctoral student and the study’s first author.
In a lab test, half of the mice that received the treatment after having a tumor removed survived for at least 60 days without the tumor regrowing.
The researchers are already discussing the new device with marine biologists to determine where it would be most useful.
In tests at the U.S. Department of Energy’s National Renewable Energy Laboratory, the device converted 22.4 percent of the incoming energy from the sun, a record for that type of cell.
The advance could revolutionize thermal management designs for computer processors and other electronics.
The researchers demonstrated that the device could accurately identify handwritten numbers and items of clothing — both commonly used tests in AI studies.
The UCLA Connection Lab, to be led by Leonard Kleinrock, will foster interdisciplinary research on a range of technologies, such as blockchain, computer networks, big data and artificial intelligence.
Robert and Dorothy Webb met when they were UCLA students in the 1950s. Their giving to the campus spans four decades.
A research team led by a UCLA bioengineer has created a model to predict the effectiveness of potential treatments to help the immune system.
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.
Tiny defects in semiconductors created ‘speed bumps’ for electrons. UCLA researchers cleared the path
Their method joins a semiconductor layer and a metal electrode layer without the atomic-level defects that typically occur as part of the process commonly used now.
The process analyzes several possible risk scenarios to help doctors more thoroughly assess people who could be candidates for heart transplants.
“Tissues are wonderfully complex structures, so to engineer artificial versions of them that function properly, we have to recreate their complexity,” said UCLA professor Ali Khademhosseini.
The advance could help bring high-quality medical diagnostics into resource-poor regions, where people otherwise do not have access to high-end technology.
These “superlattices” could lead to improved and new classes of electronics, from transistors to LEDs.
The advance shows great promise for helping the body’s immune system seek out and destroy cancer cells.
In experiments the device produced 30 percent better capacitance — the measure of a device’s ability to store an electric charge — for its mass compared to the best available electrode made from similar materials.
Device that measures cell strength could help identify drugs for asthma, hypertension and muscular dystrophy
“This technology is a game-changer for us drug discovery scientists,” said Robert Damoiseaux, a UCLA professor of molecular and medical pharmacology.
The new technique sheds light on the materials the artist used, and the order in which they were applied to the painting. It also helped scientists uncover insights about the painting’s connections to other work from the same era.
