The moon's phases shaped the menstrual cycle.
Previous researchers focused on the fluorescence spectra of the α-NiS particles which were influenced by the different phases, shapes, structures, and the surface/volume ratio [23].
The phase, shape, and size of the resulting core shell NPs are confirmed by transmission electron microscopy and X-ray diffraction.
We apply the piecewise constant level set method to a class of eigenvalue related two-phase shape optimization problems.
An in vitro study using explanted porcine hearts was conducted to evaluate a novel annuloplasty band, reinforced with a two-phase, shape memory alloy, designed specifically for minimally invasive mitral valve repair.
In particular, this assessment involves a statistical characterization of the competition between crack deflection and crack penetration at matrix/reinforcement interfaces using a modified version of the energy criterion of He and Hutchinson which accounts for the effects of finite reinforcement size, phase volume fractions, phase shape and phase distribution.
The experimental results revealed that the phase, shape and morphology, surface property and the photocatalytic activity were greatly affected by the calcination temperatures and amount of sodium present in the different samples.
In particular, thermolysis and solvothermal method are the two most widely used methods, as they can produce precise control over the phase, shape, size, and stoichiometric composition of the core only and/or the core/shell UCNPs.
Development of facile synthesis strategies for high-quality lanthanide-doped luminescent nanoparticles with controlled composition, crystalline phase, shape, and size is crucial to tune their chemical and optical properties and explore their potential applications in diverse fields.
This Review mainly focuses on thermolysis, hydro(solvo thermal, and Ostwald-ripening, which are the most widely used methods, as they can offer precise control over the phase, shape, size, and stoichiometric composition of the core only and/or the core/shell UCNPs.
