The week in physics: Glass aging; Sustainability in space; Scientific sanctions against Russia

Glass ages in material time Forward this email  View in your browser THE WEEK IN PHYSICS: 28 MARCH–1 APRIL Advertisement Peering inside carbon nanotubes When Vikram Deshpande wanted to study the behavior of electrons coursing through carbon nanotubes, he turned to ICEoxford's DRY ICE 1.5K 70 mm cryostat. See how the cryostat is allowing the University of Utah physicist to conduct innovative measurements of delicate quantum effects. Read now. Q&A: Moriba Jah on the sustainability of near-Earth space The astrodynamicist wants to catalog and better track the growing population of stuff in space and hold people accountable for their behavior in the space environment. Toni Feder Glass ages in material time The long-standing assumption that the same relaxation processes underlie linear and nonlinear aging is now backed up by experiments. Christine Middleton Whitepaper Five criteria for high-quality Raman microscopes Confocal Raman imaging and related techniques continue to increase in popularity. This whitepaper describes five key factors to consider when evaluating instrumentation: speed, sensitivity, resolution, modularity and upgradeability, and combinability. Read now. FROM THE VAULT: March 1972 The concept of the photon It has its logical foundation in the quantum theory of radiation. But the "fuzzy‐ball" picture of a photon often leads to unnecessary difficulties. Marian O. Scully and Murray Sargent III Ukraine invasion triggers push to cut science ties with Russia Governments and science organizations around the world are grappling over the degree to which sanctions against Russia should extend to scientific exchanges. Mitch Ambrose Whitepaper Compact, self-contained pulsed lasers expand capabilities in 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.

FROM THE APRIL MAGAZINE How did Mars lose its atmosphere and water? They were mostly lost to space early in Mars's history, in processes driven by the Sun's UV photons and solar wind after Mars lost its magnetic field. Bruce M.
