Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...
The β′ and QC rod-shaped precipitates, observed in the Al-Mg-Si and Al-Cu-Mg-Si alloys, respectively, are studied by transmission electron microscopy (TEM). Superstructure images and microdiffraction patterns confirm the likeness between the β′ and QC phas ...
The microstructure of an AlCu4Mg1Ag alloy reinforced with 15 vol% Al2O3-Saffil fibers was investigated by analytical transmission electron microscopy and compared to the microstructure of the unreinforced alloy. The investigation results show that the comp ...
High-resolution transmission electron microscopy (HRTEM), electron microdiffraction, and X-ray diffraction were used to study hydroxyapatite specimens with particle sizes from a few nanometers to several hundreds of nanometers. Diffuse scattering (without ...
The mechanical properties of continuous fibre reinforced metals (CFRMs) are known to be very sensitive to the selection and composition of the metallic matrix; for aluminium based CFRMs, commercial alloys are not suitable for this purpose. In the present s ...
A comparative characterization of crystal structure, morphology, sizes, and orientation in Ca phosphate precipitation from aqueous solutions, the mineral phase in bones, and mineral deposits on cardiac valves has been performed by high-resolution transmiss ...
The precipitation state of the Al-Cu-Mg-Si and Al-Mg-Si alloys was investigated by TEM, EDS and HREM. In the Al-Cu-Mg-Si alloys, it has been shown that a structural phase transition exists between 3 phases: Q-Al5Cu2Mg8Si6, QC and QP. These phases, which ha ...
Polyethylene block-copolymer films containing negative anhydride groups were used to immobilize TiO2, Fe2O3, and Fe3+ photocatalysts. The kinetics of the mineralization of azo-dye Orange II and chlorophenols on copolymer−TiO2, copolymer−Fe2O3, and copolyme ...
The precipitation state of an Al-4 wt% Cu-1 wt% Mg-Ag alloy reinforced with SiC particles fabricated by squeeze casting is studied by transmission electron microscopy. As a consequence of an interfacial reaction the precipitation of the characteristic phas ...
A large variety of physical analysis techniques are used in the semiconductor industry to identify defects impacting yield or reliability. Identification of a defect often requires the combined use of several techniques to give a clear understanding of th ...
