4 Museum oil paintings just gained new advocates who are using novel testing methods to aid conservators in preserving these cultural treasures. Metal carboxylates knowns as “metal soaps” mysteriously form on paintings over time and damage the artwork. The phenomenon is most common with paints containing zinc and lead. Researchers at the National Institute of Standards and Technology (NIST) and the National Gallery of Art have teamed up to use infrared-light-based methods to identify the composition and distribution of themetal soaps. Various spectroscopy techniques such as photothermal induced resonance (PTIR) are used to gain a broader view of the chemical composition across various layers of paint samples. The PTIR method can provide chemical mapping to give conservators information about the initial factors causing the unusual formation and to help with preservation strategies. In another example of salvaging history, see our Research Tracks page for details on how the U.K. is using materials testing to refurbish a maritime icon, the HMS Victory. The first phase of the project involves extensive control tests on the metal fasteners, caulking, and paint that could be used to restore the 18th century warship. Only the materials proven most weatherproof will be deemed worthy of this royal project. From the British Isles we take you southwest to Chile, where our lead article offers an archaeometallurgical study of its ancient copper coins. Currency is a tangible artifact of any country’s heritage. Various figureheads, flowers, buildings, and mottos are minted to commemorate and elevate the values of that government. Materials characterization can serve a vital role in analyzing coins by providing insight into the raw materials, process, and equipment used in their minting. The resulting research can paint a rich picture of the culture, the peoples, and their values that created the coinage. Our members have been doing a bit of excavating and curating themselves lately. With the return of in-person conferences, our presenters are dusting off their travel bags. More importantly, they mined through the last two years of pandemic-stifled research and selected the gems—their own Mona Lisa’s—to submit as abstracts to our ASM conferences. Many ASM members attended the successful AeroMat event in Pasadena. Next up is the International Thermal Spray Conference in Vienna followed by the International Conference on Shape Memory and Superelastic Technologies in San Diego. You can find show previews for both events in the iTSSe and SMST NewsWire supplements. And then see page 1 to get jazzed for IMAT in New Orleans this September. Come to these events for the best-of-the-best research, reclaimed and honed from a global quarantine. Enjoy reviving your professional network. And thank your colleagues, anywhere in the world, who are applying materials science to noble conservation efforts. They are preserving culture—one coin, one ship, and one painting at a time. joanne.miller@asminternational.org A D V A N C E D M A T E R I A L S & P R O C E S S E S | A P R I L 2 0 2 2 ASM International 9639 Kinsman Road, Materials Park, OH 44073 Tel: 440.338.5151 • Fax: 440.338.4634 Joanne Miller, Editor joanne.miller@asminternational.org Victoria Burt, Managing Editor vicki.burt@asminternational.org Frances Richards and Corinne Richards Contributing Editors Jan Nejedlik, Layout and Design Madrid Tramble, Production Manager madrid.tramble@asminternational.org Press Release Editor magazines@asminternational.org EDITORIAL COMMITTEE Adam Farrow, Chair, Los Alamos National Lab John Shingledecker, Vice Chair, EPRI Somuri Prasad, Past Chair, Sandia National Lab Beth Armstrong, Oak Ridge National Lab Margaret Flury, Medtronic Surojit Gupta, University of North Dakota Nia Harrison, Ford Motor Company Michael Hoerner, KnightHawk Engineering Hideyuki Kanematsu, Suzuka National College of Technology Ibrahim Karaman, Texas A&M University Ricardo Komai, Tesla Scott Olig, U.S. Naval Research Lab Amit Pandey, Lockheed Martin Space Satyam Sahay, John Deere Technology Center India Kumar Sridharan, University of Wisconsin Jean-Paul Vega, Siemens Energy Vasisht Venkatesh, Pratt & Whitney ASMBOARDOF TRUSTEES Judith A.
