Lubricants - Page 2

E2 Holdings, working with 2DM, recently launched an engine oil additive formulated with high purity graphene. The product, called NAMITEC, is said to improve fuel economy, restore power and performance, reduce noise and vibration, extend engine life and more. 

The Company explains that graphene as a lubricating additive can reduce the coefficient of friction due to its capability to produce a nano-bearing protective layer for the moving parts of your engine. SG Graphene NAMITEC engine oil additive is suitable for all gasoline and diesel engines, as well as machinery and tools.

Haydale recently announced it will be partnering with CERN, the European particle physics laboratory, on a new project aimed at improving the durability of the lubricants currently used on some of the world’s largest particle physics equipment including the Large Hadron Collider.

Polymers in the oils and greases currently used are heavily susceptible to radiation damage leading to degradation of the lubricant. Using Haydale’s HDPlas® process, the aim is to increase the lifetime of the lubricants by adding functionalized nanomaterials, including graphene. The goal is to increase the material’s resistance and better dispersion characteristics should help to achieve this. As well as the potential for significant cost savings, increasing the service life of the lubricants in use is perhaps even more important given the highly limited access there is in these areas.

The Enlit Europe 2022 energy conference recently took place, and the Graphene Flagship participated, showing some of the latest energy-related graphene projects. We took the chance to discuss graphene with some of the flagship researchers, and we also talked to Prof. Jari Kinaret, the director of the flagship project, to learn of how he summarizes the last 10 years now that the flagship project will soon end.

Q: We understand that the Graphene Flagship is attending Enlit Europe 2022, showing some new graphene R&D projects. We'll be happy to get an overview of what will be displayed at the event.

At Enlit Europe, the Graphene Flagship exhibited innovations from its Spearhead Projects, which are industry-led initiatives working to move materials from research labs towards commercial applications. Among these initiatives are:

• CircuitBreakers, led by ABB and developing first-of-their-kind grease-free, maintenance-free, low-voltage circuit breakers for fault protection in key parts of the electrical grid;
• GRAPES, led by Enel Green Power and working on combining silicon solar cells with perovskite solar cells, paving the way for low-cost, highly efficient photovoltaic energy, surpassing the limits of silicon based cells.

A team of researchers from Korea's Pusan National University, led by Assistant Professor Songkil Kim, have examined the relationship between surface structures on chemical vapor deposition (CVD) grown graphene and its properties, specifically friction.

They correlated surface structures with nanoscale friction of a multi-layered graphene island. By cleaning the graphene surface using mechanical scratching of polymeric surface contamination, the team unveiled the surface structures such as small-scale and large-scale (folded) wrinkles on graphene using atomic force microscopy (AFM) and investigated their effect on nanoscale friction.

Gigabyte launched a new graphic cards that uses a graphene lubricant that is said to extend the lifetime of the fan by 2.1 times, almost like a double ball bearing design - and it also makes the fab quieter compared to the company's designs that do not use graphene.

The GeForce RTX 3070 EAGLE OC 8G rev 2.0 features Nvidia's RTX 3070 GPU clocked at 1725 Mhz, with 8GB of GDDR6 memory. It is now shipping at $1,199.

Researchers at Graphene-XT have developed a new graphene-based lubricating oil additive for diesel and petrol engines in cars or motorcycles.

By introducing graphene into a lubricating oil, Graphene-XT found that both its performance and stability improved, resulting in more compression and less wear and tear in the engine parts of both cars and motorcycles.

Gigabyte announced its latest gaming graphic card, the Radeon RX 6800 GAMING OC 16G. The new device uses a graphene-enhanced lubricant for its fan.

Gigabyte says that its "Graphene nano lubricant" extends the lifetime of the fan by 2.1 times, almost like a double ball bearing design - and it also makes the fab quieter compared to the company's previous design.

Sweden-based Applied Nano Surfaces (ANS) launched a new product, Tricolit GO, one of the first graphene-enhanced low-friction coatings on the market today. Tricolit is available now from ANS, in easy-to-apply spray cans or in bulk. The product can be used to reduce friction and wear. ANS claims that the use of graphene allows a tenfold increase in the coating’s mechanical strength and abrasion-resistance.


We have talked to ANS CTO, Boris Zhmud, and he revealed that ANS uses graphene dispersions from UK-based Applied Graphene Materials. Tricolit GO is still considered an "experimental" product. The development was financed by Sweden's SIO-Grafen.

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have been working replace oil with solid lubricants such as graphene. Argonne’s Laboratory Directed Research and Development (LDRD) Program supplied the seed money needed to begin experimentation towards that end. This work may have far reaching implications both inside and outside the automobile industry. It could help wind turbines move with greater ease, allowing them to produce more energy. It also can better seal off machinery as it pumps oil or gas from the ground or out at sea.

Graphene can also be used to better protect ball bearings, which can corrode over time when exposed to water, a process commonly referred to as tribo-corrosion. The Argonne-developed process based on graphene has shown that a few layers of graphene not only reduced friction in steel rubbing against steel by seven times and the wear by 10,000 times but also significantly reduced the tribo-corrosion problem.

A new initiative called "The Technical Standards Development and Application Demonstration Base of Graphene-Modified Lubricants" was launched at LiuGong’s Global R&D Center in Liuzhou, China. Co-built by the China Innovation Alliance of the Graphene Industry and Guangxi Liugong Machinery (a leading China-based construction equipment manufacturer), it aims to become a major base in China that concentrates on the transformation of graphene’s scientific research into real world applications.

The partnership also includes building a joint laboratory and undertaking independent test tasks from other companies in the future. The initiative will push the R&D and innovation of graphene-modified lubricant products at LiuGong and will also give the firm a chance to participate in drafting industry standards directly.
