Kinematic and spermatic recovery after selection by centrifugation in colloid solutions of ovine cryopreserved semen
(2016-01-01)
Frozen and thawed ovine semen undergo morphological and functional changes that prevent or decrease the efficiency of fertilization. Sperm selection methods seek to improve the quality and viability of the fertilizing ...
Sperm membrane integrity and stability after selection of cryopreserved ovine semen on colloidal solutions
(2018-03-01)
The aim of this study was to evaluate the effect of four methods of sperm selection, on the integrity and stability of the plasma membrane, integrity of the acrosomal membrane and spermatic morphology in frozen/thawed ovine ...
Designing Colloidal Silica-Bonded Porous Structures of In-situ Mullite for Thermal Insulation
(2020-09-01)
Abstract: Colloidal silica (CS) is a promising raw material for refractory castable ceramics. It consists of stable suspensions of synthetic amorphous silica nanoparticles that behave simultaneously as liquid medium and ...
Submicron silica shell–magnetic core preparation and characterization
(2018-01-20)
The magnetic extraction, purification, labeling and detection of biomolecules and cells are widely applied recently. In addition, the synthesis of silica magnetic particles for biomedical applications has been developed. ...
Evaluation of modified silica nanoparticles in carboxylated nitrile rubber nanocomposites
(2014)
Surface-modified silica nanoparticles have a plenty of applications, such as coatings, dyes or biomarkers, catalysts and encapsulated products. When modified with 3-(trimethoxysilyl)propyl methacrylate (SiO2-MPS) or covered ...
Effect of colloidal silica on the mechanical properties of fiber-cement reinforced with cellulosic fibers
(Springer, 2014-11-01)
The effect of colloidal silica on the hydration reaction of the Portland cement system and its effect on the resulting mechanical properties are not completely understood. Silica nanoparticles can affect the behavior and ...
Controlling dispersion, stability and polymer content on PDEGMA-functionalized core-brush silica colloids
(Elsevier Science, 2019-08)
Core-brush hybrid nanoparticles containing PEG surface functions are highly interesting as biologically inert and smart stimuli-responsive materials for future applications in biosensors, drug delivery, tissue engineering ...
Eco-Concrete for Hydraulic Structures with Addition of Colloidal Nano-Silica
(Institute of Physics Publishing, 2020-02-28)
In the construction of buildings and infrastructures, high resistance materials are used due to current design requirements, concrete being one of the main materials used in the execution of these projects whose cement ...
