Recently, several types of nacre-like materials have been developed using various methods. However, the resulting materials exhibit a significant randomness and defects compared to natural nacre. Therefore, evaluating the influence of these microstructural variations on the material’s mechanical behavior is of high interest for the development of n...

Monitoring nitrate ions is essential in agriculture, food industry, health sector and aquatic ecosystem. We show that a conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), can be used for nitrate sensing through a process in which nitrate ion uptake leads to oxidation of PEDOT and change of its optical properties. In this study, a new pla...
Cold Sintering Process has been applied to hydroxide precursors Al(OH) 3 , xH 2 O to promote in situ reactive sintering. The application of sintering temperatures

YxAlyB14 ceramics are of high interest as high temperature thermoelectric materials with excellent p, n control. In this study, direct synthesis of dense polycrystalline YxAlyB14 (x ~0.64, 0.52 ≤ y ≤ 0.67) ceramics was successfully carried out by spark plasma sintering using commercially available precursors. YB4, AlB2 and B powders were reactively...
La cerámica analizada en este artículo se reconoce como resultado de la interacción indohispánica en la región habanera. Se enfatizan las características y significación de estos artefactos, en los que se evidencian rasgos identitarios autóctonos, así como la supervivencia de individuos reconocidos socialmente como indios naturales, hacedores de lo...
The Wari State was the first expansionistic power to develop in the Andean highlands. Emerging in the area of modern Ayacucho (Peru) around AD 650, the Wari expanded to control much of the central Andes by the time of their collapse at AD 1000. This book describes the discovery and excavation (2010-2012) of a major new Wari site (Espíritu Pampa), ...

Lead free (0.94-x)Na0.5Bi0.5TiO3–0.06BaTiO3-xK0.5Na0.5NbO3 ceramics are under the spotlight owing to their multifunctional nature. We have systematically investigated the microstructural, structural, dielectric, piezoelectric and energy storage properties of the system in the range 0 ≤ x ≤ 0.08. There is a systematic reduction in grain size with in...

Soldering SiC using Sn-based solder can lower residual interface stress due to low soldering temperature. Active elements can play key roles in interfacial bonding between Sn-based solder and SiC ceramics. In this study, density functional theory (DFT) calculation was performed to evaluate whether Ti, Al, Zr and Ag atoms can act as active elements ...

Historical archaeologists often view curated or heirloom pottery as a frustrating anomaly in the dating of historical-period sites or contexts. Fewer pause to consider why the artifacts were curated in the first place, or what their presence reveals about the people who maintained them. Drawing on a case study of curated micaceous pottery at a Hisp...
