Comparison of Permanent Magnetic Motor and Induction Motor on power efficiency in Electric Submersible Pump

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Artificial Lift is utilized to produce oil from a well with no natural flow or to increase the oil production of naturally flow well. One method for artificial lift is the installation of Electric Submersible Pump or ESP. ESP is the most common method and widely used to lift oil from a well.

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.
