Scientists design ‘smart’ device to harvest daylight

Researchers behind the ‘smart’ device to harvest daylight are Assistant Professor Yoo Seongwoo (left) from the School of Electrical and Electronics Engineering and Dr Charu Goel (right), Principal Research Fellow at NTU’s The Photonics Institute Credit: NTU Singapore A team of Nanyang Technological University, Singapore (NTU Singapore) researchers has designed a ‘smart’ device to harvest daylight and relay it to underground spaces, reducing the need to draw on traditional energy sources for lighting. In Singapore, authorities are looking at the…

Rapid material testing during sheet metal processing reduces failure and scrap

In the testing machine, a hemispherical stamp pushes the component down to a defined depth. The force-displacement profile is analyzed to allow detailed conclusions to be drawn about the quality of the material. Credit: Fraunhofer-Gesellschaft Fraunhofer researchers have developed an innovative process for the initial testing of sheet metal in production systems. The process involves combining tried and proven load tests with an AI software solution. Even before the first machining step, the software creates a prediction about how the…

Research Team Training AI to Better Detect Small Objects

Professor Yi Shang and team are developing a deep learning system that will better identify small objects such as waterfowl in images.   Artificial Intelligence (AI) is good at recognizing a single bird in an image. Where it falls short is when it tries to identify hundreds of tiny birds in an aerial photo. Professor Yi Shang and his research team have been working for three years to see where AI can improve its vision when it comes to small…

Electronics-free DraBot dragonfly signals environmental disruptions

With the ability to sense changes in pH, temperature and oil, this completely soft robot dubbed “DraBot” could be the prototype for future environmental sentinels. Credit: Vardhman Kumar Engineers at Duke University have developed an electronics-free, entirely soft robot shaped like a dragonfly that can skim across water and react to environmental conditions such as pH, temperature or the presence of oil. The proof-of-principle demonstration could be the precursor to more advanced, autonomous, long-range environmental sentinels for monitoring a wide…

A New Way to Visualize Mountains of Biological Data

This is a general example of a type of visual that a graph neural network can create with provided biological data.   By Eric Stann | MU News Bureau  Studying genetic material on a cellular level, such as single-cell RNA-sequencing, can provide scientists with a detailed, high-resolution view of biological processes at work. This level of detail helps scientists determine the health of tissues and organs, and better understand the development of diseases such as Alzheimer’s that impacts millions of…

Big breakthrough for ‘massless’ energy storage

Structural battery composite fabrication, showing the steps: battery component manufacture, pouch‐cell manufacture, and curing of the SBE. Credit: Advanced Energy and Sustainability Research (2021). DOI: 10.1002/aesr.202000093 Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially ‘massless’ energy storage in vehicles and other technology. The batteries in…

Nanotech scientists create world’s smallest origami bird — ScienceDaily

If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas. But just as importantly, if you want your robot to move, you need it to be able to bend. Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material…

Rao Invited to Serve on Environmental Health Sciences Review Committee

Praveen Rao has been invited to serve as a member of the Environmental Health Sciences Review Committee, which serves as an advisory board to the National Institutes of Health (NIH). Members are appointed for a 3-year term. Rao is an associate professor with joint appointment in Electrical Engineering & Computer Science and Health Management & Informatics. The committee’s primary responsibility is to review applications for environmental health sciences core centers, institutional training grants, career awards and other specialized applications that…

In the wake of the great winter storm, how can Texas create a more resilient power grid?

Credit: Unsplash/CC0 Public Domain As temperatures plummeted below freezing for 10 straight days and snow and ice blanketed Texas, all eyes turned to the state’s power grid to understand how 4.5 million Texan customers could lose electricity at once. Frigid temperatures wreaked havoc on Texas’ natural gas, nuclear and coal plants, as well as wind turbines that struggled to operate during the storm. Many have blamed the Electric Reliability Council of Texas (ERCOT), the energy grid operator for 90% of…

Engineers’ Week 2021 Co-chairs Have Safety in Mind

2021 Engineers’ Week Co-chair Lauren Baratta As we near St. Patrick’s Day, every Mizzou Engineer knows the best week of the year is approaching quickly – Engineers’ Week!
