Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the ...

THE term viscosity has frequently been used in a qualitative sense in describing the properties of solids and particularly of metals, but its use in the quantitative sense which has been developed ...

A collaborative study by researchers from three Indian Institutes of Technology (IITs) has found that adding tetrapod-shaped nanoparticles to certain synthetic plastics can significantly reduce their ...

In the equation, yield stress is represented by σ 0 and Bingham viscosity or plastic viscosity is represented by η B. The value of Bingham viscosity provides details about the slope of the Newtonian ...

Certain plastic wastes can soon help fuel your cars. Researchers from IIT Guwahati have successfully converted packaging plastic waste to plastic-derived oil (PDO), which has characteristics similar ...

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...
