Applying the neural network technique, which uses models utilized in Natural Language Processing, Agar and his colleagues were able to directly image and visualize an important subtlety in the switching of a classical ferroelectric material: lead zirconium titanate which, prior to this, had never been done.  Materials scientists who work with nano-sized components have developed ways of working with their vanishingly small materials.  Researchers at Tokyo Institute of Technology, the University of Cambridge, and the University of Copenhagen have built a self-assembled nanocage with a very unusual nanospace: Its walls are made of antiaromatic molecules, which are generally considered too unstable to work with.  Using the new methods, the research teams have succeeded in deciphering the energy transport in double-walled nanotubes made up of thousands of dye molecules.  Researchers have developed a three-dimensional dynamic model of an interaction between light and nanoparticles.  Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite.  Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale.  Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light.  The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing.  In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source.  For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature.
