Helium is again in short supply Forward this email  View in your browser THE WEEK IN PHYSICS: 4–8 APRIL Advertisement AR's "U" Series Amplifiers Offers the Widest Bandwidth AR's "U" Series, Class A amplifiers covers a bandwidth of 10 kHz – 1000 MHz and delivers up to 500 W of power, making it ideal for EMC & laboratory testing, medical/physics research, antenna & component testing, wireless charging, & more! Imagine the possibilities with amplifiers that are Built to Last. Learn more. Helium is again in short supply The war in Ukraine isn't much of a factor, yet. David Kramer Mars's polar ice layers signal climate changes The periodicity of the layers matches that of the planet's orbital dynamics. R. Mark Wilson 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. FROM THE VAULT: November 1973 Research with the space shuttle A laboratory the size of a boxcar will be placed in earth orbit by the Space Shuttle system within the next decade, thus beginning a new era of science in space. John E. Naugle Lunar micrometeorite preserves solar system's early history Geochemical analyses show that a 200-µm-sized speck of rock likely originated somewhere other than the Moon. Alex Lopatka Whitepaper Dual Curing Adhesives For a UV curable adhesive, the cure initiates after exposure to UV light at a wavelength that is specific to the photo-initiator used in the formula. Learn more about the advantages of dual cure adhesives for your bonding, coating, sealing or encapsulation application. Read now. The AIP Books Donation program A two-decade-old program seeks to advance the physical sciences globally by shipping books to understocked physics libraries. Tonya Gary New books: April 2022 A listing of newly published books spanning several genres of the physical sciences. 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. Read now. FROM THE APRIL MAGAZINE Unveiling exozodiacal light Nulling interferometry draws aside bright stellar glare to probe fine dust in extrasolar systems that may hamper future searches for Earthlike worlds.
