Glycerol photoreforming for photocatalytic hydrogen production on binary and ternary Pt-g-C3N4-TiO2 systems: a comparative study
(Elsevier, 2024)Photocatalytic hydrogen production using two sacrificial agents (triethanolamine and glycerol) was conducted on several binary (Pt/TiO2 and Pt/g-C3N4) and ternary systems (Pt on a heterojunction between TiO2 and g-C3N4 ... -
An IoT barrel bung to monitor evolution wine elaborated under biological aging
(Elsevier, 2022)Wine aging is a crucial step in the elaboration of special and high quality wines as the sherry and like-sherry type wines are. Some of these wines remain in oak barrels during a long time period, subjected to the ... -
Additive-free superhard B4C with ultrafine-grained dense microstructures
(The American Ceramic Society, 2014)A unique combination of high-energy ball-milling, annealing, and spark-plasma sintering has been used to process superhard B4C ceramics with ultrafine-grained, dense microstructures from commercially available powders, ... -
Dislocation microstructure of 4H–SiC single crystals plastically deformed around the transition temperature
(The American Ceramic Society, 2012)4H–SiC specimens were plastically deformed by basal slip at temperatures between 800 °C and 1300 °C. Samples were investigated by means of transmission electron microscopy and high-resolution techniques. The accepted ... -
Dislocation dissociation and stacking-fault energy calculation in strontium titanate
(Elsevier, 2010)The dislocation microstructure of strontium titanate plastically deformed below room temperature shows dipolar configurations of a〈1 1 0〉 screw dislocations. The dipole height is so small that dipole annihilation is expected. ...
