A bit of stray moisture during an experiment tipped off scientists about the strange behavior of a complex oxide material they were studying - shedding light on its potential for improving chemical sensors, computing and information storage.
Researchers have studied in detail, a slow change of microscopic magnetic structures in metallic wires induced by external driving forces, commonly called 'creep' motion. This has allowed them to clarify the physics of how the driving forces, magnetic fields or electric currents, act on the magnetic structure.
Using X-ray photoelectron spectroscopy - a technique used to examine the surface chemistry of a solid material - researchers have begun to understand the operating principles and sensing mechanisms behind promising nanocomposite thin film materials.
Scientists are investigating the use of nanoparticles as a way to disinfect wounds. It could prove to be much more effective than existing techniques because the particles would be tiny enough to enter the skin via hair follicles, ensuring much better penetration of the area affected by surgery.
