Thermo-mechanical recycling of rubber: Relationship between material properties and specific mechanical energy [PDF]
Journal of Materials Processing Technology, 2018 The studied and optimized devulcanization process is known as " High Shear Mixing " (HSM) recycling process. In the process the rubber is sheared between two metallic cones with special geometries. One cone is static as the other one rotates simultaneously and applies pressure to the material.

Optimization of Operating Parameters for Minimum Mechanical Specific Energy in Drilling [PDF]
, 2019 Efficiency in drilling is measured by Mechanical Specific Energy (MSE). MSE is the measure of the amount of energy input required to remove a unit volume of rock, expressed in units of energy input divided by volume removed. It can be expressed mathematically in terms of controllable parameters; Weight on Bit, Torque, Rate of Penetration, and RPM.

Mechanical vapor compression—Membrane distillation hybrids for reduced specific energy consumption [PDF]
Desalination and Water Treatment, 2016 AbstractThe energy efficiency of membrane distillation (MD) systems is low when compared to other thermal desalination systems. This leads to high water production costs when conventional fuels such as natural gas are used. In MD, separation of pure product water from feedwater is driven by differences in vapor pressure between the streams.
