Size distributions of fine silicate and other particles in Masaya's volcanic plume
(Amer Geophysical Union, 2009-05-14)
Direct-sampling and remote-sensing measurements were made at the crater rim of Masaya volcano (Nicaragua) to sample the aerosol plume emanating from the active vent. We report the first measurements of the size distribution ...
Reactivity of Sedimentary and Metamorphic Limestones of Different Particle Sizes under Controlled Conditions
(2019-02-21)
The efficiency of limestone in amending soil acidity is primarily based on the particle size and the neutralization value of the ground rock, but the origin of the rock can also affect its reactivity. The aim of this work ...
Recovery of bimodal particle size distributions with multiangle dynamic light scattering
(Chinese Optical Society, 2017-02)
By using the multi-angle dynamic light scattering measurement and the weighted constrained regularization method, the four groups simulated particle systems with bimodal distribution(100/600 nm, 200/600 nm, 300/600 nm, ...
Magnetic properties of spindle-type iron fine particles obtained from hematite
(2001-12-01)
Spindle-type iron fine particles have been prepared by reduction of silica-coated-hematite particles. Hydrogen reduction of the coated-hematite cores yielded uniform spindle-type iron particles, which were stabilized by ...
Magnetic properties of spindle-type iron fine particles obtained from hematite
(2001-12-01)
Spindle-type iron fine particles have been prepared by reduction of silica-coated-hematite particles. Hydrogen reduction of the coated-hematite cores yielded uniform spindle-type iron particles, which were stabilized by ...
Effect of Particle Size and Quality of Pruning Wood Residues of Asian Pear (Pyrus pyrifolia and Pyrus communis) On C-And N-Mineralisation in Soils of Contrasting Textures
(Sociedad Chilena de la Ciencia del Suelo, 2006)
Influence of particle size on the adsorption and release of cephalexin encapsulated in mesoporous silica SBA-15
(Elsevier Science, 2016-10-13)
Ordered mesoporous silicas with different particle sizes were synthesized and used as drug carrier in controlled delivery systems. Morphological properties of mesoporous supports were modified by changing the stirring rate. ...
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. ...
Influence of different factors on the particle size distribution and solid fat content of water-in-oil emulsions
(Springer, 2016-04)
The influence of the variation of different parameters on the particle size distribution and solid fat content (SFC) of water-in-oil emulsions was studied. The use of solid fat instead of liquid oil, higher polyglycerol ...
Effects of the fractal structure and size distribution of flocs on the removal of particulate matter
(2016-08-01)
This study sought to evaluate the effect of form and particle size distribution of formed flocs during flocculation on the removal of particulate matter (PM) by settling. The understanding of the intrinsic processes of ...
