Electrons in materials have properties known as ‘spin’, which is responsible for various properties, the best known of which is magnetism. Permanent magnets, such as those used for refrigerator doors, have to align all spins in their electrons in the same direction. Scientists refer to this behavior as ferromagnetism, and research fields of trying to … Read more
A team of researchers from the UCLA Samueli School of Engineering has demonstrated a new approach to an old problem: measuring the spectra of light, also known as spectroscopy. Taking advantage of scalable, cost-effective nano-fabrication techniques, as well as AI-driven algorithms, they built and tested a system that is more compact than traditional spectrometers, while … Read more
An international team of scientists have invented the equivalent of body armor for extremely fragile quantum systems, which will make them strong enough to be used as the basis for a new generation of low-energy electronics. The scientists applied the armor by gently squeezing liquid metal gallium droplets onto the material, coating them with gallium … Read more
Tiny nanoparticles can be equipped with dyes and used for new imaging techniques as chemists and physicists at a recent study, Martin Luther University Halle-Wittenberg (MLU) show. Researchers have also been the first to completely determine the internal structure of particles. Their results were published in the famous magazine Angvende Chemi. Single-chain nanoparticles (SCNPs) are … Read more
The development of the scanning microscope in the early 1980s brought a breakthrough in imaging, opening a window into the world. The main idea is to scan a very sharp tip on a substrate and record the strength of the interaction between the tip and the surface at each location. In scanning force microscopy, this … Read more
