Researchers have developed a new way to use atomic force microscopy to rapidly measure the mechanical properties of cells at the nanometer scale, an advance that could pave the way for better understanding immune disorders and cancer.
Understanding and manipulating plasmons is important for their potential use in photovoltaics, solar cell water splitting, and sunlight-induced fuel production from CO2. Researchers have used a real-time numerical algorithm to study both the plasmon and hot carrier within the same framework. That is critical for understanding how long a particle stays excited, and whether there is energy backflow from hot carrier to plasmon.
Researchers have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the metamaterial.
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.
