Researchers deepen understanding of friction in graphene

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 launches a new graphics card with a graphene lubricant

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.

Gigabyte uses graphene to extend the lifetime of graphic card fans and minimize noise

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.

ANS launches a graphene-fortified polymer-bonded coating

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.
