Study on the Evaluation Method of Sludge Formation during the Oxidation Process of Gear Oils

Tribology Online, 2013
Generally synthetic gear oils have superior oxidation stability compared to mineral gear oils, although there is a concern that the oil life may depend on the sludge formation during its oxidation process. In the methods of ASTM D2893 or ASTM D5763 which

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...
