BASF 2016 science competition seeks synthetic lubricant solutions for future high-efficiency vehicles
March 31, 2016
BASF has kicked off its second annual North American Science Competition. This year’s competition focuses on chemistries that can be used to develop a synthetic fluid to meet the needs of future high-performance, high-efficiency engines and transmissions.
With more advanced machinery, lubricating and functional fluids represent a steadily growing industry projected to reach $11 billion by 2020. Synthetic fluids, which are more expensive than petroleum-derived materials, address increasing market demands for higher quality and purity, increased performance and more stringent environmental standards. By developing high performing synthetic fluids with better thermal stability, BASF aims to extend the life cycle of these materials, reduce waste and support the development of more fuel-efficient vehicles.
Northwestern researchers discover crumpled graphene balls are a promising lubricant additive
January 26, 2016
Researchers at Northwestern University’s McCormick School of Engineering have found that crumpled graphene balls are an extremely promising lubricant additive. In a series of tests, a polyalphaolefin base oil with only 0.01–0.1 wt % of crumpled graphene balls outperformed a fully formulated commercial lubricant in terms of friction and wear reduction. A paper on their work is published in the Proceedings of the National Academy of Sciences.
For the average car, 15% of the fuel consumption is spent overcoming friction in the engine and transmission. While oil helps reduce this friction, researchers have long sought additives that enhance oil’s performance. Ultrafine particles are often used as lubricant additives because they are capable of reducing friction and protecting surfaces from wear. They also tend to be more stable than molecular additives under high thermal and mechanical stresses during rubbing. However, they also can aggregate, reducing the effective concentration.
Amyris/Cosan JV Novvi introduces 100% renewable Group III and IV base oils
May 27, 2015
Novvi LLC, a joint venture of Amyris, Inc. and Cosan S.A. Industria e Comercio, unveiled two new 100% renewable base oil—the main component of motor oils—products: a renewable polyalphaolefin (PAO) Group IV and a renewable version of its NovaSpec Group III+ base oil. The new base oil products add to Novvi’s growing portfolio of renewable oils.
The Novvi JV was created to develop, produce, market, and distribute high-performance oils and lubricants from renewable sources. Novvi applies Amyris’ synthetic biology platform to produce targeted hydrocarbon molecules from plant sugar and Cosan’s feedstock capabilities and supply and distribution infrastructure.
