The week in physics: Artificial spin ice; Bacterial vibrations; Helping Ukrainian scientists

Entropy and order work together in an artificial spin ice Forward this email  View in your browser THE WEEK IN PHYSICS: 18–22 APRIL Advertisement Introducing one of our newest systems, the TURBOLAB Core Leybold is now pleased to present a new addition to the line, the TURBOLAB Core. It offers all the reliability, power, and ease of setup you would expect from a Leybold product. The various add-ons this pumping station can support simultaneously allow for the adaptability to meet the needs of almost any application. Learn more. Graphene drums detect jiggling cells A new technique measures a single bacterium's nanoscale vibrations with sufficient precision to pinpoint their origin. Christine Middleton Entropy and order work together in an artificial spin ice Counterintuitively, the very factor that propels most of the universe toward disorder pushes an array of nanomagnets into a visibly ordered state. Johanna L. Miller Webinar Live Webinar: Equation-Based Modeling with COMSOL Multiphysics® Learn about how you can set up and solve your own equations in COMSOL Multiphysics®. Expect useful advice on formulating the equations, combining equation-based modeling with predefined physics interfaces, and assessing the results. Register now. FROM THE VAULT: January 1949 The physics of metals With the end of the war international scientific meetings began to revive and the summer of 1948 saw American physicists sailing to Europe in considerable numbers. Physics Today here presents a report of a conference on metals held in July by the International Union of Pure and Applied Physics at Amsterdam. John C. Slater Whitepaper Compact lasers expand LIBS applications In this white paper, we introduce a very compact, air-cooled, pulsed laser and show it can be used successfully in conventional Laser Induced Breakdown Spectroscopy (LIBS) experimental set-ups for identifying metals.

May issue preview Further delays at ITER are certain, but their duration isn't clear A halt to construction, pandemic-caused delays in deliveries, labor strife, and concerns about potential beryllium exposure are among recent challenges to the fusion project. David Kramer Q&A: Oleksandra Romanyshyn on helping Ukrainian scientists The biomedical engineering graduate student started a scholarship program that she hopes to expand in light of the Russian invasion of Ukraine. Heather M. Hill Whitepaper Sensitive EQE Device Characterization A look at performing sensitive external quantum efficiency (sEQE) characterization as a means for studying low-energy phenomena, such as charge transfer states, traps, and defects in solar cell technologies. Lock-in detection is used in sEQE to extract the small photoresponse at long wavelengths. Read now.
