UW team first to measure microscale granular crystal dynamics
ME assistant professor Nicholas Boechler and UW engineers have, for the first time, analyzed interactions between microscale granular crystals. Granular materials resonate into complex patterns when forces are applied to them. Microscale granular crystals have significantly different reactions to forces than better-understood macroscale particles. Understanding how microscale granular crystals self-assemble in response to forces could enable faster and less expensive ways to manufacture microstructed materials like spacecraft shielding.

UW researchers unleash graphene ‘tiger’ for more efficient optoelectronicsMSE associate professor Xiaodong Xu and colleagues have developed a promising approach to increasing optoelectronic efficiency. The key to making efficient light-captured energetics possible is to coax one photon into stimulating multiple electrons. Xu directed photons towards a "superlattice" of graphene sandwiched between two layers of boron-nitride. The superlattice creates regions of huge electron density, where one energized photon can transfer its energy to as many as five electrons. According to collaborator Sanfeng Wu, “Graphene is a tiger with great potential for optoelectronics, but locked in a cage. The singularities in this superlattice are a key to unlocking that cage and releasing graphene’s potential for light harvesting application.”

This five-fingered robot hand learns to get a grip on its own
UW engineers have built a 5-fingered robot hand that learns dexterous manipulation on its own, rather than having its actions programmed. Intricate tasks like rolling, pivoting, bending, and sensing friction are notoriously difficult for robots. Now, engineers in the UW Movement Control Laboratory have built a robot hand that can perform dexterous manipulation and learn from its own experience without needing human direction.

The Twittersphere does listen to the voice of reason — sometimesHCDE's emCOMP lab has found that tweets from "official accounts" can slow the spread of rumors on Twitter and correct misinformation that’s taken on a life of its own. "Avoiding social media channels because you don't want to be confronted with misinformation is a real danger for an organization. You're essentially opening up a space for information to be spreading without your voice being a part of it." – Kate Starbird, UW assistant professor of human-centered design and engineering

Doctor, patient expectations differ on fitness and lifestyle tracking
HCDE researchers found doctors lack the tools and capacity to interpret a deluge of fitness, food and lifestyle data that patients are self-tracking. In a study that won a best paper award and will be presented at the ACM conference on Computer-Supported Cooperative Work and Social Computing, the UW team surveyed 211 patients and interviewed 21 doctors, dietitians and other health care providers about their expectations for how patients' self-tracking data should be shared and used.
"We've heard doctors say more and more that people bring this data into the clinic and they’re just overwhelmed by it," said lead author Christina Chung, a UW doctoral student in Human Centered Design & Engineering. The team, which includes UW physicians, computer scientists and engineers, is exploring ways to make self-tracking data more clinically useful and to help health care providers and patients collaboratively engage with it.

NASA data used to track groundwater in Pakistan
UW civil and environmental engineers helped Pakistani water managers access free NASA satellite data to monitor groundwater changes in Pakistan's vast farmland areas, where setting up a traditional monitoring network had taken nearly eight years in one province alone.
"Satellites up in space looking at how much water we have underground, in rivers or in the atmosphere are providing routine observations that can help policymakers and on-the-ground managers make informed decisions," said Faisal Hossain, UW associate professor of civil and environmental engineering. "From offering improved flood forecasting to indicating areas where groundwater resources are threatened, freely available satellite data can be an invaluable resource, particularly in developing countries." Hossain runs the UW Sustainability, Satellites, Water and Environment Research Group.
