Worldwide Research on Energy Efficiency and Sustainability in Public Buildings
(MDPI, 2017)The present study details the significant contribution that different international institutions have made to the field of sustainability and energy efficiency, with a focus on public buildings. This has been achieved ... -
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): I. Dislocation organization
(Elsevier, 2009)Under a load orientation that hinders twinning and impedes fracture, sapphire and Cr-doped α-Al2O3 single crystals (rubies) were deformed from 1500 °C to slightly above the brittle to ductile transition temperature of 900 ... -
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): II. Dissociation and stacking faults
(Elsevier, 2009)Sapphire and rubies (undoped and Cr-doped α-Al2O3 single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocations in the basal slip plane. Above 1400 °C, several ...
