Estudio de la Evolución de la Microestructura y Dureza de Aleaciones Cu-V y Cu-V-Al Durante su Fabricación por Molienda Reactiva y Extrusión
(Universidad de ChilePrograma Cybertesis, 2008)
Morphology and phase formation during the solidification of Al-Cu-Si and Al-Ag-Cu ternary eutectic systems
(Universidade Federal de São Carlos, 2018-02-26)
The microstructure of ternary alloys in the Al rich corner of the Al-Cu-Si and Al-Ag-Cu systems were analyzed in order to determine the solidification path in the different structural regions expected from the equilibrium ...
Understanding Cu incorporation in the Cu2xHg2-xGeTe4 structure using resonant x-ray diffraction
(Amer Physical Soc, 2021-01-15)
The ability to control carrier concentration based on the extent of Cu solubility in the Cu2xHg2-xGeTe4 alloy compound (where 0 <= x <= 1) makes Cu2xHg2-xGeTe4 an interesting case study in the field of thermoelectrics. ...
Síntese e caracterização de complexos de Cu(I), Cu(II) E Au(I) com ligantes triazenidos contendo substituintes triazóis
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-11-29)
Triazenido ions are isoelectronic to amidinato anions,[R'N C(R)=NR']- and have a broad versatility in coordination chemistry. Metal complexes including triazenido ligands find applications in various areas of chemistry. ...
Cu/Al and Cu/Cr based layered double hydroxide nanoparticles as adsorption materials for water treatment
(2018)
Cu/Al and Cu/Cr layered double hydroxides (LDH) were synthesized using a simple co-precipitation method at room temperature. These particles were further modified by Co+2 incorporation, and calcined at 500 degrees C for ...
Antimicrobial Cu-functionalized surfaces prepared by bipolar asymmetric DC-pulsed magnetron sputtering (DCP)
(Elsevier Science Sa, 2011-05-30)
Cu-cotton fabrics were functionalized by bipolar asymmetric DC-pulse magnetron sputtering (DCP). The DCP of Cu-particles on cotton proceeds at a higher energy than DC-magnetron sputtering (DC). The different sputtering ...
Thermal and electrochemical studies of Cu(II) 8-hydroxyquinoline organophilic montmorillonite
(2018-01-01)
The thermal and electrochemical behavior of montmorillonite clay-8-hydroxyquinoline (8-HQ) film was studied in the absence and presence of aqueous Cu(II) ions. The suggested formation of the ternary complex type: ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
