Sharper Diffraction Images Advancing a research technique such as ultra-fast electron diffraction will help future generations of materials scientists to investigate materials and chemical reactions with new precision. [28] But an international group led by Prof. Beena Kalisky and Prof. Aviad Frydman, from the Department of Physics and the Institute for Nanotechnology at Bar-Ilan University in Israel, has succeeded in imaging quantum fluctuations for the first time. [27] To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos. [26] An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. [25] A kiwi physicist has discovered the energy difference between two quantum states in the helium atom with unprecedented accuracy, a groundbreaking discovery that contributes to our understanding of the universe and space-time and rivals the work of the world's most expensive physics project, the Large Hadron Collider. [24] Physicists and material scientists have succeeded in constructing a motor and an energy storage device from one single component. [23] Heat pipes are devices to keep critical equipment from overheating. They transfer heat from one point to another through an evaporation-condensation process and are used in everything from cell phones and laptops to air conditioners and spacecraft. [22] Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an algorithm that can discover and optimize these materials in a matter of months, relying on solving quantum mechanical equations, without any experimental input. [21] Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. [20] Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive paint. [19] A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. [18]
