U-Pb SHRIMP geochronology of zircon from the Catoca kimberlite, Angola: Implications for diamond exploration
(Elsevier Science, 2012-06)
We present the first age determinations of zircon from the diamondiferous Catoca kimberlite in northeastern Angola, the fourth largest kimberlite body in the world. The U-Pb ages were obtained using a Sensitive High ...
Magnetoelastic couplings in the distorted diamond-chain compound azurite
(Amer Physical Soc, 2014-05-27)
We present results of ultrasonic measurements on a single crystal of the distorted diamond-chain compound azurite Cu-3(CO3)(2)(OH)(2). Pronounced elastic anomalies are observed in the temperature dependence of the longitudinal ...

Major- and trace-element compositions of indicator minerals that occur as macro- and megacrysts, and of xenoliths, from kimberlites in Northeastern Angola
(MDPI, 2012-10)
In this study, we compare the major- and trace-element compositions of olivine, garnet, and clinopyroxene that occur as single crystals (142 grains), with those derived from xenoliths (51 samples) from six kimberlites in ...
Frictional properties of surface textures fabricated on hardened steel by elliptical vibration diamond cutting
(Elsevier Inc., 2019)
Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...

Thermoelastic and mechanical properties in diamond, c-BN, c-SiC, TiO 2 , TiO 1.85 and w-ZnO
(Springer, 2019-11)
Thermoelastic and mechanical properties have been obtained in materials with high (diamond, c-SiC, c-BN), medium (TiO2, TiO1.85) and low (w-ZnO) hardness by means of ab initio calculations. Our methodology combines the ab ...
