| Unprecedented view of a single catalyst nanoparticle at work Posted: 01 Oct 2021 12:27 PM PDT A research team has been using high-intensity X-rays to observe a single catalyst nanoparticle at work. The experiment has revealed for the first time how the chemical composition of the surface of an individual nanoparticle changes under reaction conditions, making it more active. This study marks an important step towards a better understanding of real, industrial catalytic materials. |
| Two-dimensional hybrid metal halide device allows control of terahertz emissions Posted: 01 Oct 2021 12:27 PM PDT Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal efficiency than conventional terahertz generators, and is thinner, lighter and less expensive to produce. |
| Low-cost, portable device could diagnose heart attacks in minutes Posted: 01 Oct 2021 10:02 AM PDT Researchers have developed a sensor that could diagnose a heart attack in less than 30 minutes, according to a new study. |
| 'Mini psyches' give insights into mysterious metal-rich near-earth asteroids Posted: 01 Oct 2021 10:02 AM PDT New research into metal-rich asteroids reveals information about the origins and compositions of these rare bodies that could one day be mined. |
| Posted: 30 Sep 2021 07:48 AM PDT Researchers developed a fluorescence quenching assay to probe the integrity of the cell membrane coating of biomimetic nanoparticles (NPs) , discovering that the great majority of the cell membrane coated NPs were only partially coated when the traditional coating techniques were applied. |
| Extending the power of attosecond spectroscopy Posted: 29 Sep 2021 07:18 AM PDT Scientists have shown that the powerful transient absorption spectroscopy technique can unravel ultrafast motion of electrons and nuclei in a molecule in real time and with atomic spatial resolution. |
