A simple drop of olive oil in a system of photons bouncing between two mirrors has revealed universal aspects of phase transitions in physics. [42] Scientists at the University of South Florida have reached a new milestone in the development of two-dimensional supramolecules-the building blocks that make areas of nanotechnology and nanomaterial advancement possible. [41] In 1965, a renowned Princeton University physicist theorized that ferroelectric metals could conduct electricity despite not existing in nature. [40] Cornell researchers have become the first to control atomically thin magnets with an electric field, a breakthrough that provides a blueprint for producing exceptionally powerful and efficient data storage in computer chips, among other applications. [39] This "piezomagnetic" material changes its magnetic properties when put under mechanical strain. [38] Researchers have developed a new flexible sensor with high sensitivity that is designed to perform variety of chemical and biological analyses in very small spaces. [37] In a new paper published today in Science Advances, researchers under the direction of Columbia Engineering Professors Michal Lipson and Alexander Gaeta (Applied Physics and Applied Mathematics) have miniaturized dual-frequency combs by putting two frequency comb generators on a single millimeter-sized chip. [36] Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. [35] The unique platform, which is referred as a 4-D microscope, combines the sensitivity and high time-resolution of phase imaging with the specificity and high spatial resolution of fluorescence microscopy. [34] The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. [33] This scientific achievement toward more precise control and monitoring of light is highly interesting for miniaturizing optical devices for sensing and signal processing. [32]
