Time-resolved spectroscopy studies of Gd2SiO5 : Ce3+ from spherical particles
(Elsevier B.V., 2014)
Comment on "The surface potential of a spherical colloid particle: Functional theoretical approach"
(Academic Press Inc Elsevier Science, 2006-12)
In a work published in this journal by Z.W. Wang, G.Z. Li, D.R. Guan, X.Z. Yi, and A.J. Lou [J. Colloid Interface Sci. 246 (2002) 302], an iterative method for the determination of the potential around a colloidal particle ...
Preparation and characterization of spherical silica-porphyrin catalysts obtained by the sol-gel methodology
(Elsevier B.V., 2006-03-01)
This work describes the synthesis of a first-generation iron porphyrin catalyst entrapped in a silica matrix by the sol-gel route, leading to spherical particles. The catalyst was synthesized by the method of Stober, through ...

Scattering of intersecting spherical particles in the Rayleigh-Gans approximation
(Elsevier, 2011-02-01)
In this work a novel semianalytical procedure to calculate the exact scattering behavior of complex particles made of intersecting spheres in the Rayleigh-Gans approximation is presented. Pickering emulsions, Janus ...
DEVELOPMENT OF AN AUTOMATED METHOD TO PERFORM A QUANTITATIVE STUDY OF PARTICLE SIZE DISTRIBUTION AND THE EFFECT OF A CONDUCTIVE LAYER IN SCANNING ELECTRON MICROSCOPY
(Sociedade Brasileira de Química, 2019-04-01)
The determination of particle size distribution is an important parameter for controlling industrial processes, particularly in the field of pharmaceuticals. It is also an important parameter for characterizing nanoparticles. ...
Colloidal particles: Spherical yttrium iron garnet
(Materials Research Society, 1998-01-01)
The purpose of this work is to obtain spherical particles YIG from micrometric to nanometric scales. The spherical particles were obtained from cation hydrolysis in acid medium by adding urea or ammonia in order to carry ...

Surface temperature distribution on a spherical ice particle growing by accretion in wet growth regime
(John Wiley & Sons Ltd, 2019-10)
Experimental evidence has demonstrated that temperature on the surface of an ice particle growing by accretion is not uniform. This non-uniformity is relevant because the ice particle surface temperature is an important ...
