Decoding battery health

May 26, 2020

With the advent of autonomous vehicles, smartphones and drones, lithium-ion batteries have become the device of choice for powerful and long-lasting energy. However, to ensure that the batteries are safe and effective, researchers need to find out what’s happening on the inside to make sure they’re healthy.

UC Davis engineering projects fight COVID-19

May 20, 2020
With new seed grants from the UC Davis Office of Research’s COVID-19 Research Accelerator Funding Track (CRAFT), three teams of UC Davis engineers are applying their expertise toward the pandemic response to help people become safer, healthier and better-tested.

Seongkyu Lee receives NSF high-performance computing grant to study drone noise

May 01, 2020

Anyone who has seen a small drone flying knows loud buzzing sound it makes as it flies. This sound—the result of air flowing around the vehicle, through the blades and between the rotors—is a barrier to wider acceptance of drones and a problem mechanical and aerospace engineering assistant professor Seongkyu Lee hopes to help solve.

Giving humanity a hand with supernumerary robotics

February 06, 2020

A team of UC Davis researchers look to give humanity an extra hand—literally. A new, NSF-funded collaboration between the Departments of Mechanical and Aerospace Engineering (MAE) and Neurobiology, Physiology and Behavior (NPB) plans to develop and test a robotic fifth limb to give humans extra capabilities in extreme environments.

Seongkyu Lee partners with Hyundai to develop low-noise air taxis

January 09, 2020

Urban air mobility (UAM), or the use of air taxis, is poised to be the next big thing in transportation. Companies are already promising fleets in traffic-congested cities like San Francisco, Los Angeles and Dallas as early as 2023, and Morgan Stanley estimates that the UAM business will create a $1.5 trillion market in the coming decades.

Why Drones Are Important in Sustainable Agriculture in the 21st Century

December 10, 2019
The work of a four-member international team of scientists including UC Davis mechanical and aerospace engineer Zhaodan Kong, a newly-published review paper in the Journal of Economic Entomology is one of the first of its kind to summarize scientific literature on the use of agricultural drones for pest management.

Space Engineering at UC Davis

October 30, 2019

If space is the final frontier, UC Davis is taking giant leaps to reach it. With expertise in human-machine cooperation, control systems and materials under extreme conditions, the university aims to make itself a rising star in space engineering and play a crucial role in the next generation of space exploration.

Modeling small cigar smoke in the lungs

October 07, 2019
Young people are adopting new nicotine products faster than they can be researched or regulated, though the health effects are still unknown. MAE distinguished Professor Tony Wexler looks to change this by studying smoke deposition in the lungs through a three-year grant from the UC Tobacco-Related Disease Research Program (TRDRP).

A Breath Test for Opioids

October 03, 2019

By Andy Fell, originally posted on UC Davis News.

A test to detect opioid drugs in exhaled breath has been developed by engineers and physicians at the University of California, Davis. A breath test could be useful in caring for chronic pain patients as well as for checking for illegal drug use. 

Giving Electric Car Batteries a Second Life

September 20, 2019

Though electric cars are great for the environment, the batteries they use are not. Because recycling is extremely expensive, they end up thrown into storage at car dealerships or buried in landfills. As electric cars become an increasingly large part of the market, Mechanical and Aerospace Engineering Professor Jae Wan Park and his lab have found an inexpensive and environmentally-friendly solution to this problem by giving these batteries a second life in electrical energy storage systems for renewable energy power grids.

Microbes Make Chemicals for Scent Marking in a Cat

September 16, 2019
Domestic cats, like many other mammals, use smelly secretions from anal sacs to mark territory and communicate with other animals. A new study from the University of California, Davis, shows that many odiferous compounds from a male cat are actually made not by the cat, but by a community of bacteria living in the anal sacs.

Can Science Save Citrus?

August 27, 2019
Farmers and researchers, including MAE Professor Cristina Davis, try to hold off deadly citrus greening long enough to find a cure

Exotic Synchronization Patterns Emerge in a Simple Network

March 07, 2019
In a new paper published March 8 in Science, a team led by researchers at the University of California, Davis, and the California Institute of Technology show how complicated and surprising behavior can emerge in a very simple experimental network.
