A Critical Review on Semi-solid and Solid Lubricants for Industrial Applications
Abstract: Friction materials are very important for the safe moving of automobiles and the safety of people. As the pad slides against its match, the moving energy is turned into heat by the friction. As the vehicle's speed is lost as heat in the pads and rotors, the friction at the contact slows it down. Lubricants are compounds that are applied to moving parts to reduce friction and wear. Used primarily …

ML-Driven Defect Detection in Additive Manufacturing of Polymer Composites Using Thermal Imaging
Abstract: Polymer-based flexible biosensors have emerged as a pivotal technology in continuous health monitoring, yet their deployment in real-world settings is often hindered by undetected micro-defects and signal distortion caused during fabrication or usage. Existing diagnostic frameworks typically rely on post-hoc processing or bulky instrumentation, failing to offer scalable, real-time detection during additive manufacturing workflows. This study introduces an end-to-end, thermographic imaging-integrated framework for in-situ defect identification during the additive manufacturing …
