Atomic-scale optical spectroscopy revealed huge Raman scattering when an atomic point contact is formed between a plasmonic silver tip and a single-crystal silicon surface. The huge Raman scattering allows to observe selectively surface phonons of the single-crystal silicon and to resolve the atomic-scale structures. Atomic point contact Raman scattering paves the way for ultrasensitive atomic-scale vibrational spectroscopy to investigate surface structures.
In an international collaboration, researchers at the University of Stuttgart were able to detect quantum bits in two-dimensional materials for the first time. Nature Materials covers this in its May 6, 2021 issue.
MIT physicists have found a novel way to switch antiferromagnetism on and off, which could lead to faster, more secure memory storage.
Developing a new generation of artificial muscles and soft nanorobots for drug delivery are some of the long-term goals of 4D-BIOMAP, an ERC research project being undertaken by the Universidad Carlos III de Madrid (UC3M).This project develops cross-cutting bio-magneto-mechanical methodologies to stimulate and control biological processes such as cell migration and proliferation, the organism's electrophysiological response, and the origin and development of soft tissue pathologies.
In a study that could help to bring inexpensive, efficient perovskite solar cells one step closer to commercial use, researchers found a way to strengthen a key weak point in the cells' internal structure, dramatically increasing their functional life.
Researchers at CRANN (The Centre for Research on Adaptive Nanostructures and Nanodevices), and the School of Physics at Trinity College Dublin today announced that a magnetic material developed at the Centre demonstrates the fastest magnetic switching ever recorded. This discovery demonstrates the potential of the material for a new generation of energy efficient ultra-fast computers and data storage systems.
2D superconductors have drawn considerable attention both for the fundamental physics they display as well as for potential applications in fields such as quantum computing. Although considerable efforts have been made to identify them, materials with high transition temperatures have been hard to find. Materials featuring both superconductivity and non-trivial band topology have proven even more elusive. A recent Nano Letters paper predicts just such a material in the easily exfoliable, topologically non-trivial semimetal W2N3.
Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.
Researchers are listening in on honeybee hives, hoping to decipher their complex communication patterns and what they might signal about broader ecosystem health. A novel method for monitoring colony health through changes in its electrostatic field is released in a recent paper by the open access publisher Frontiers.
Exploring extreme environments can put significant operational challenges on the engineering systems we depend upon to safely explore and at times operate within.
