Researchers at Ohio State University have created a new method for shaping metal using magnetism, eliminating the need for industrial lubricants. The 'bump forming' technique increases the depth of metal parts by up to 47% while reducing production costs and environmental impact.
Kodali and Nivens have developed a series of commercial lubricants, Agri-Pure 500, made from modified vegetable oils that overcome gelation and degradation issues. The oils can be used in environmentally sensitive areas and as base oils for hydraulic fluid and crankcase oil.
Researchers Clifford G. Venier and Edward W. Casserly developed a new lubricant called Pennzane® Synthesized Hydrocarbon Fluid X2000 that can withstand extremely low temperatures and prolong satellite life. The lubricant also enhances the longevity of car oils and provides thin coatings for computer disk drives.
Researchers found that larger sprocket sizes and higher chain tension can significantly increase bicycle drive train efficiency, while lubrication has a minimal impact. The study's results could have implications for other chain-driven devices, including conveyor belts and factory production lines.
In a groundbreaking study, researchers directly observed molecules of liquid forming three solid-like layers near a solid surface. The findings suggest that liquids do not behave like bulk liquids in confined geometries and have significant implications for the development of lubricants and thin film coatings.
Researchers at Georgia Tech discovered a way to reduce friction in mechanical systems by rapidly oscillating the width of the lubricant-filled gap separating two sliding surfaces. This technique maintains disorder in the lubricant, preventing molecular layering that can increase friction.
Researchers at the Weizmann Institute of Science have developed a new material that outperforms existing lubricants in industrial conditions. The material, made of tungsten disulfide fullerene-like molecules, reduces friction between moving metal parts by less than half and wear by up to six times.
Scientists have discovered that randomness in lubricants is a major contributor to friction at the molecular level. This finding could lead to reduced wear and tear on machinery. By understanding how lubricants fracture and heal, researchers may develop new methods to control friction and minimize wear.
Researchers at Penn State have discovered that certain vegetable oil formulations can perform as well or better than commercial standards in tests for high-temperature resistance, slipperiness, and evaporation loss. This breakthrough has the potential to provide a more environmentally friendly alternative to traditional lubricants.
