This work presents a cell to measure the dynamic viscosity of liquids using a wave mode conversion from longitudinal to shear waves and vice-versa. The method is based on the measurement of the complex reflection coefficient of shear waves at a solid-liquid interface. The reflected waves at the solid-liquid interface are measured in the longitudinal mode by a large aperture PVDF membrane to avo...

We present a microfluidic rheometer that uses in situ pressure sensors to measure the viscosity of liquids at low Reynolds number. Viscosity is measured in a long, straight channel using a PDMS-based microfluidic device that consists of a channel layer and a sensing membrane integrated with an array of piezoresistive pressure sensors via plasma surface treatment. The micro-pressure sensor is fa...

Viscosity ($\eta$) is one of the most important properties disordered matter. The temperature-dependence viscosity used to adjust process variables for glass-making, from melting annealing. aim this work was develop a physics-informed machine learning model capable predicting $\eta(T)$ oxide liquids. Instead itself, NN predicts parameters MYEGA equation: liquid's fragility index, glass transiti...
