Metallic structures in service seawater are protected by coupling cathodic protection and paints, where the former may induce disbondment of latter. A preliminary evaluation risk can be made tests (CDTs). Many CDTs use potentials as large E < −1400 mV versus saturated calomel electrode (SCE) applied up to 90 days. Only two CDT protocols require contemporary anode isolation, current pH monitorin...

A new mineral species, markascherite (IMA2010-051), ideally Cu3(MoO4)(OH)4, has been found at Copper Creek, Pinal County, Arizona, U.S.A. The mineral is of secondary origin and is associated with brochantite, antlerite, lindgrenite, wulfenite, natrojarosite, and chalcanthite. Markascherite crystals are bladed (elongated along the b axis), up to 0.50 × 0.10 × 0.05 mm. The dominant forms are {001...

While the versatile composition of layered double hydroxides (LDHs) allows introduction almost any polyvalent cation in their structure, exchangeable negatively charged ions intercalated between plates increase vast range functionalities. Here we report on preparation and optical properties pillared Eu3+-substituted ZnAl LDHs by aliphatic dicarboxylates: ?OOC?(CH2)n–2?COO?. The basal distance t...
