If you've ever tried to lift a pizza slice covered in hot, melted cheese, you've no doubt encountered the long, cheesy strings that bridge one pizza slice from the next. Keep lifting the pizza slice and these cheese bridges eventually break, covering the plate, table (or even your lap) in long, thin strands of cheese. While this is just a minor inconvenience with pizza, it is a longstanding problem in industry, where liquids with similar properties to melted cheese - dubbed viscoelastic fluids - need to be cleanly and speedily dispensed.
As a new member of photovoltaic family, antimony trisulfide (Sb2S3) has the satisfactory bandgap of 1.7eV, benefiting the fabrication of the top absorber layer of tandem solar cells. Due to special quasi-one-dimensional structure, it shows advantages of less dangling bonds.
Superconductors are something like a miracle in the modern world. Their unique property of zero resistance can revolutionize power transmission and transport (e.g., Maglev train). However, most of the conventional superconductors require cooling down to extremely low temperatures that can only be achieved with liquid helium, a rather expensive coolant.
Chemical engineers at the University of Illinois Chicago and UCLA have answered longstanding questions about the underlying processes that determine the life cycle of liquid foams. The breakthrough could help improve the commercial production and application of foams in a broad range of industries.
The U.S. Department of Energy awarded Jin Hu, a physicist at the U of A, with a prestigious Early Career Research Program award to support his research on topological quantum materials, which have promising applications in information storage and quantum computing.
Researchers have developed an alternative to synthetic filters using marine bath sponges.
In a new study, North Carolina State University researchers demonstrated they could print layers of electrically conductive ink on polyester fabric to make an e-textile that could be used in the design of future wearable devices.
Dr. Igor Ivanishin, a postdoctoral researcher in the Harold Vance Department of Petroleum Engineering at Texas A&M University, has firsthand experience with the frustrations of oil production.
A study led by University of Minnesota Twin Cities researchers uncovered a property of magnetic materials that will allow engineers to develop more efficient spintronic devices in the future.
What is already established for inorganic semiconductors continues to be a challenge for their organic counterparts — that is, tuning the energy gap by mixing various semiconducting molecules to improve the performance of the device.
