| Researchers develop 3D-printed shape memory alloy with superior superelasticity Posted: 13 May 2022 02:07 PM PDT Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although this manufacturing technique is attractive for applications in the biomedical and aerospace fields, it has rarely showcased the superelasticity required for specific applications using nickel-titanium shape memory alloys. Defects generated and changes imposed onto the material during the 3D-printing process prevented the superelasticity from appearing in 3D-printed nickel-titanium. |
| Going gentle on mechanical quantum systems Posted: 13 May 2022 10:49 AM PDT Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum properties of such systems can be measured without destroying the quantum state -- a key ingredient for tapping the full potential of mechanical quantum systems. |
| Malaria parasites form vortices Posted: 13 May 2022 10:48 AM PDT Researchers managed to set larger groups of malaria parasites into motion and to analyze the acquired image data. The collectively moving pathogens form vortex systems that are largely determined by physical principles. Computer simulations helped identify the mechanisms underlying these rotating movements. |
| Remote sensing research improves hurricane response Posted: 13 May 2022 10:48 AM PDT Researchers are investigating better ways to predict where road-clogging debris will be most severe after tropical cyclones. |
| Dragonflies use vision, subtle wing control to straighten up and fly right Posted: 13 May 2022 08:32 AM PDT Researchers have untangled the intricate physics and neural controls that enable dragonflies to right themselves while they're falling. |
| When quantum particles fly like bees Posted: 12 May 2022 11:43 AM PDT A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system's behavior is child's play for a quantum simulator. But verifying the result is almost impossible, even with today's supercomputers. A research team has now shown how these systems can be verified using equations formulated in the 18th century. |
| Towards more efficient, non-toxic, and flexible thin-film solar cells Posted: 12 May 2022 06:27 AM PDT While solar cells are a great alternative to fossil fuels, the environmental impact of the processes involved in manufacturing solar cells has been a concern. Solar panel fabrication often involves toxic materials such as cadmium and industrial waste. In a new study, researchers have now developed an eco-friendly method that eliminates the use of toxic cadmium in the production process to produce cost-effective, efficient, and eco-friendly solar cells. |
| A nontoxic glue for plywood -- from glucose, citric acid Posted: 11 May 2022 05:57 AM PDT The go-to materials for building home furniture, décor and floors are composite wood products that come in large sheets. But the glues and resins holding together particleboard, fiberboard and plywood usually contain formaldehyde and could release this probable carcinogen into the air. To develop a nontoxic adhesive, researchers have combined glucose and citric acid -- sugar and an orange juice ingredient -- into a strong, water-resistant wood glue for plywood. |
