Parametric study of strength of silica gels
Journal of Non-Crystalline Solids, 1994Abstract Cylindrical gel bodies were produced by using Si(OC2H5)4, C2H5OH and H2O with various catalysts. A systematic parametric study of gel strength and microstructure as a function of C2H5OH/H2O molar ratio and catalyst concentration in sol, catalyst type as well as aging time, was conducted.

Determination of the tensile strength of gels
Journal of Polymer Science, 1955AbstractA method has been devised and an apparatus constructed for measuring the tensile strength of viscoelastic gels. The method consists of extruding the gel vertically through a nozzle of diameter of 2–14 mm. and weighing the gel‐column falling by its own weight.

Development of high-strength gel dosimeter made by 3D gel printer
Nano-, Bio-, Info-Tech Sensors, and 3D Systems II, 2017In the radiation therapy, ionization chambers and/or film dosimeters are usually used to measure dose distribution, and three-dimensional absorbed dose distribution of the human body is calculated by computer simulation. However, at the treatment site, measurements of actual three-dimensional absorbed dose distribution become more important, because ...

High‐Strength Cellulose/Poly(ethylene glycol) Gels
ChemSusChem, 2008AbstractCellulose gel membranes have been prepared by a pre‐gelation method employing cellulose solutions in aqueous NaOH–thiourea obtained at low temperature. The cellulose gels were then swollen by low‐molecular‐weight polyethylene glycol (PEG; MW<1000 g mol−1), and the morphology, structure and mechanical properties of the cellulose/PEG gels were

Dynamic viscoelasticity of fibrin gels: Dependence on ionic strength
Thrombosis Research, 1976Abstract The dynamic rigidity and loss moduli of fibrinogen solutions with various ionic strengths are determined during clotting. The kinetic analysis of the clotting curves indicates that the fibrin gels formed at high and low ionic strengths consist of non-flexible thick fibrous bundles, while those formed at moderate ionic strengths consist of ...

The Relationship of Thickening Time. Gel Strength, and Compressive Strength of Oilwell Cements
SPE Production Engineering, 1986Summary A previous investigation1 of the effect of thickening times on early compressive-strength and gel-strength development has been expanded to include a wider range of well conditions, a greater variety of slurry types, and a more thorough evaluation of static gel strength.

Microfabrication of High-Strength Gels with a 3D Printer
ECS Meeting Abstracts, 2018Using 3D printer Acculas, we fabricated a high-intensity particle double network gel (P-DN gel) . In this apparatus, the spot diameter of the UV laser to be irradiated can be set to 30 to 300 μm and the z pitch can be set to 30 μm at minimum. The data used was mesh of size 250 μm and the set value of spot diameter was 30 μm.

Correlation of FTIR spectra of protein gels to rheological measurements of gel strength
1995Globular proteins are important ingredients in many food formulations because of their nutritional value and their various functional properties such as gel formation. Proteins form gels by polymerization into a three-dimensional matrix. The rheological properties of the resulting viscoelastic solids can be obtained by Instron measurements.
