Spectroscopic Investigation of the Coloration and Fabrication Conditions of Medieval Blue Glasses

21.08.2015 | Myrtille Hunault, Fanny Bauchau, Claudine Loisel, Michel Hérold, Laurence Galoisy, Matthew Newville, Georges Calas, Journal of the American Ceramic Society, 2015

Potash‐ and soda‐lime‐stained glasses from the 12th–13th centuries, blue‐colored by cobalt, have been investigated by Mn, Fe, and Cu K‐edge X‐ray and optical absorption spectroscopies in order to determine the oxidation state of these elements and their impact on the blue color. Remelting these ...

Preparation of 4,4′‐diaminostilbene‐2,2′‐disulfonic acid intercalated LDH/polypropylene nanocomposites with enhanced UV absorption property

21.08.2015 | Yanshan Gao, Yufei Zhao, Lei Qiu, Zhanhu Guo, Dermot O'Hare, Qiang Wang, Polymer Composites, 2015

The UV absorber 4,4′‐diaminostilbene‐2,2′‐disulfonate (DASDSA) has been successfully intercalated into an inorganic host Zn2Al layered double hydroxide (Zn2Al‐DASDSA LDH), which is expected to lead stabilization and protection of this thermally unstable UV absorber. Using a modified solvent ...

Materials, Vol. 8, Pages 5452-5466: X-Ray Spectroscopy of Ultra-Thin Oxide/Oxide Heteroepitaxial Films: A Case Study of Single-Nanometer VO2/TiO2

21.08.2015 | Quackenbush, Nicholas F.; Paik, Hanjong ; Woicik, Joseph C.; Arena, Dario A.; Schlom, Darrell G.; Piper, Louis F. J., Materials, 2015

Epitaxial ultra-thin oxide films can support large percent level strains well beyond their bulk counterparts, thereby enabling strain-engineering in oxides that can tailor various phenomena. At these reduced dimensions (typically < 10 nm), contributions from the substrate can dwarf the signal ...
