“Dicamba drift”—the movement of the herbicide dicamba off crops through the atmosphere—can result in unintentional damage to neighboring plants. To prevent dicamba drift, other chemicals, typically amines, are mixed with dicamba to “lock” it in place and prevent it from volatilizing, or turning into a vapor that more easily moves in the atmosphere.

Now, new research from the lab of Kimberly Parker, an assistant professor of energy, environmental and chemical engineering at Washington University in St. Louis’ McKelvey School of Engineering, has shed new light on this story by demonstrating for the first time that these amines themselves volatilize, often more than dicamba itself.

Their findings were published Sept. 23 in the journal Environmental Science and Technology.

Compressed air energy storage (CAES) is expected to play a key role in China’s clean energy push and the latest project announcement attests to the fact.

According to a media statement from the state-owned Assets Supervision and Administration Commission of the State Council, construction started on a 350 MW/1.4 GWh CAES project in the province of Shangdong on September 28.

Once completed, the Tai’an demonstration project is expected to be the world’s largest salt cavern CAES project, comprising two units for a total of 600 MW. The 350 MW system, which will be delivered in the first phase, is being jointly built by China Energy Engineering Group and Tai’an-based Taian Taishan New Energy Development to the tune of CNY 2.23 billion ($311 million).

Researchers from North Carolina State University and The University of Texas at Austin have discovered a unique property in complex nanostructures that had previously only been seen in simple nanostructures. They have also uncovered the internal mechanics of the materials that allow for this property to exist.

The findings were reported in a recent paper that was published in the journal Proceedings of the National Academy of Sciences. The scientists found these properties in oxide-based “nanolattices,” which are tiny, hollow materials with a structure resembling that of sea sponges.

“This has been seen before in simple nanostructures, like a nanowire, which is about 1,000 times thinner than a hair,” said Yong Zhu, a professor in the Department of Mechanical and Aerospace Engineering at NC State, and one of the lead authors on the paper. “But this is the first time we’ve seen it in a 3D nanostructure.”

The engineering of so-called Floquet states leads to almost-perfect atom-optics elements for matter-wave interferometers—which could boost these devices’ ability to probe new physics.

Since Michelson and Morley’s famous experiment to detect the “luminiferous aether,” optical interferometry has offered valuable tools for studying fundamental physics. Nowadays, cutting-edge applications of the technique include its use as a high-precision ruler for detecting gravitational waves (see Focus: The Moon as a Gravitational-Wave Detector) and as a platform for quantum computing (see Viewpoint: Quantum Leap for Quantum Primacy). But as methods for cooling and controlling atoms have advanced, a new kind of interferometer has become available, in which light waves are replaced by matter waves [1]. Such devices can measure inertial forces with a sensitivity even greater than that of optical interferometers [2] and could reveal new physics beyond the standard model.

The Indian Electric Vehicle market is set to reach a sales volume of 10.8 lakh units by 2025. However, these vehicles are currently at a high price and are not affordable to consumers in low-income categories.

To bridge this gap, a team of seven students at the KL University, Hyderabad have retrofitted an old and discarded bike into an EV.

“We also added futuristic features including wireless charging and cell balancing, which ensures equalised charging,” says Charan Sai (21), a fourth-year student of Electronics and Electrical Engineering, and the lead of the project.

A collaborative research team co-led by City University of Hong Kong (CityU) has developed a wearable tactile rendering system, which can mimic the sensation of touch with high spatial resolution and a rapid response rate.

The team demonstrated its application potential in a braille display, adding the sense of touch in the metaverse for functions such as virtual reality shopping and gaming, and potentially facilitating the work of astronauts, deep-sea divers and others who need to wear thick gloves.

Deltec Homes is changing the way the world builds. For over five decades, we have designed and engineered homes to fight climate change and withstand the harshest of weather conditions. The connections, both inside and out, that our homes provide make it truly the strongest home for people and our planet.

The engineering and innovation behind each Deltec is why they have stood against some of the most detrimental storms in history including direct hits from Hurricanes Dorian, Michael, Maria, Irma, Harvey, Sandy, Katrina, Hugo, Ivan and Charley.
