Viscosity measuring cell using ultrasonic wave mode conversion
(Taylor & Francis Ltd, 2006-01-01)
This work presents a cell to measure dynamic viscosity of liquids using ultrasonic wave mode conversion from longitudinal to shear wave. The strategy used to obtain the viscosity is based on the measurement of the complex ...
Use of DSC in degree of conversion of dimethacrylate polymers: easier and faster than MIR technique
This work aims to determine the degree of conversion of polymers obtained using diurethane dimethacrylate (UDMA) monomer by two different techniques: differential scanning calorimetry (DSC) and Fourier transform infrared ...
Effect of pre-heating resin composite and light-curing units on monomer conversion
The purpose of this study was to evaluate the effect of pre-heating resin composite photo-cured with light-curing units (LCU) by FT-IR. Twenty specimens were made in a metallic mold (4 mm diameter × 2 mm thick) from composite ...
