Homologous series of LC acrylic monomers based on phenyl benzoate core group: synthesis and characterisation
(Taylor & Francis, 2020)
The synthesis and phase characterisation of a homologous series of monomers of acrylic phenyl benzoates has been carried out. The characterisation comprises polarised optical microscopy, differential scanning calorimetry ...
Ab initio calculations of elastic properties of compressed Pt
(2007)
First-principles calculations of the equation of state and single-crystal elastic constants of platinum have been carried out to 650 GPa using density-functional theory (DFT). The present equation of state deduced at 300 ...
Chemical composition and phase identification of sodium titanate nanostructures grown from titania by hydrothermal processing
(Elsevier, 2007)
Fine titanium dioxide particles were hydrothermally treated in a sodium hydroxide aqueous solution. The treatment extended from 1
to 6 days leading to belt-like and wire-like structures of a metastable phase of sodium ...
Nonhydrostatic compression of bismuth to 222 GPa: Some constraints on elasticity of the bcc-phase
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)
Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
Strength of polycrystalline coarse-grained platinum to 330 GPa and of nanocrystalline platinum to 70 GPa from high-pressure x-ray diffraction data
(AMER INST PHYSICS, 2008-03-15)
X-ray diffraction patterns from platinum foil 300 nm grain size have been recorded up to
330 GPa using a beveled-anvil diamond cell. The compressive strength has been determined from
the analysis of the diffraction ...
Heterocyclization of 3-deoxy-D-erythro-hexos-2-ulose-1,2-bis(thiosemicarbazone). Crystal structure of the major diastereomer
(2002)
Both thiosemicarbazone groups of the derivative 1 of 3-deoxy-D-erythro-hexos-2-ulose underwent, on acetylation, a heterocyclization process to give (5R,5′R)-2,2′-diacetamido-4,4′-di-N-acetyl-5′-(1- deoxy-2,3,4-tri-O-acet ...
Crystal structure, optical and magnetic properties of perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles: An experimental and first-principles studies
(Elsevier Ltd, 2019)
The perovskite Gd(Mn0.7Ni0.3)O3 ceramic nanoparticles were synthesized by a facile sol-gel technique. The structure, electronic structure, surface morphology, optical and magnetic properties of GdMn0.7Ni0.3O3 nanoparticles ...
Synthesis and characterisation of two homologous series of LC acrylic monomers based on phenolic and resorcinic azobenzene groups
(Taylor & Francis, 2016)
The synthesis and phase characterisation of two homologous series of monomers of acrylic azo-compounds has been presented. The characterisation comprises polarising optical microscopy (POM), differential scanning calorimetry ...
Using advanced mineral characterisation techniques to estimate grinding media consumption at laboratory scale
(Elsevier, 2018-06)
Grinding media is very important in the mineral processing, mainly because its consumption involves significant costs of grinding and consequently, of the total mining operational expenditure. During grinding, chemical and ...
Molybdenum trioxide thin films doped with gold nanoparticles grown by a sequential methodology: photochemical metal-organic deposition (PMOD) and DC-magnetron sputtering
(Sociedad Chilena Química, 2016)
Gold nanoparticles (AuNPs) were deposited by DC-magnetron sputtering onto molybdenum trioxide (MoO3) thin films grown by Photochemical Metal-Organic Deposition (PMOD) on Si(100) and borosilicate glass substrates. The ...
