Exciting graphene products and prototypes showcased at the Graphene Pavilion at the Mobile World Congress in Barcelona this week.
Innovations ranged from IOT, datacom to sensors, wearables and energy storage.
Where is popular graphene-enhanced BAC sports car though!
Last year NGA co-organized the graphene pavilion at the first MWC America in San Francisco.
What’s the advantage:
The existence of G+ in these tires reduces rolling resistance and increasing grip (G+ is Directa Plus‘s brand of Graphene Nano Platelets).
The result is a tire that is both faster in motion and safer in turning under braking or in extreme weather conditions.
Good for those of us who like to drive!
“The benefits of incorporating G+ into tyres have been demonstrated by the Company’s longstanding relationship with Vittoria group, a leading manufacturer of bicycle tyres. Vittoria has launched multiple award-winning G+ bicycle tyres for on-road and off-road use. The Company is also conducting ongoing tests with other automotive and potential industrial partners of its G+ elastomeric composition for tyres.”
Congrats Giulio Cesareo for Directa’s 17th patent.

Graphene Tattoo, the thinnest wearable health monitor by The University of Texas at Austin.
We saw a great talk on this by Deji Akinwande at the Graphene Innovation Summit in October in Nashville.
“The graphene tattoo is a dry physiological sensor which, because of its thinness, forms an ultra-conformal contact to skin, resulting in increased signal fidelity,” said co-author of the work Shideh Kabiri Ameri. “Conformability results in less susceptibility to motion artifacts, which is one the biggest drawbacks of conventional dry sensors and electrodes for physiological measurements.”
Last week, I asked Shideh on Linkedin, “How is the progress? Can you share any updates on the project?”
“Dear Zina, Thank you for asking. We recently lowered the thickness of the second version of the graphene electronic tattoo sensors by 25%, down to 350 nanometer. Our latest manuscript is under review and will be published soon.”
This should be interesting…looking forward to hearing more on the work.
An interesting piece by Adrian Nixon, an advisory board member of the NGA, explains the work of the Chinese group published in ACS Applied Material and Interfaces journal.
A part of this study focuses on use of honey as an organic exfoliating agent to produce graphene and Graphene Nano Platelets.
Here’s Adrian’s comment that I received earlier today:
“Hi Zina Jarrahi Cinker,
Yes you have quite rightly focused in on the role of honey as the exfoliating agent. The team in China thought that there were two reasons honey was so good. i) It had a similar surface energy to graphene ii) It had the right viscosity to help the nanoplates slide apart in the roll mill. I’m more inclined to think the viscosity is the key factor here, but if you know better I’ll defer to your expert opinion. Good to hear from you, hope all that travelling around DC pays off.
Making Monolayer Graphene from Graphite with Honey
Feb 11 is the International Day of Women and Girls in Science.
We have many extraordinary strong women in Graphene and we need more!
Flashback: Last September, San Francisco, our brilliant #WomenInGraphene at the MWCA Graphene Pavilion co-organized by National Graphene Association.

A bio-inspired material that combines a soft, self-healing polymer with a tough layer of graphene oxide could be the basis of new, ultra-tough scratch resistant coatings.
“The material features a soft self-healing layer, a mixture of tannic acid and polyvinylalcohol (PVA) which form a dynamic hydrogen-bonded network. But this is reinforced by an outer PVA layer containing nanosheets of graphene oxide – a tough material that gives greater scratch resistance. This is similar, Yang says, to the structure of the skin epidermis, where hardened outer cells protect the soft, living tissue beneath, which can repair damage.”
Skin-Mimic Material is as Tough as Teeth

Graphene and China…that has been on my mind in the past 6 months
Neill Ricketts, How was the trade visit to China?
Versarien® plc was among the select delegation on a three-day trade visit to China with UK Prime Minister Theresa May. The visit marks a new stage of relationships between UK and China regarding agreements and partnerships: particularly in services, education and technology solutions. “The opportunities are massive. If you are exporting and manufacturing you have to be here (China). You need to experience the opportunities that are here.” Said Neill Ricketts
Congrats and it is great to have you on the advisory board of the National Graphene Association, Neill.
A businessman from Gloucestershire is among the select delegation currently on a three-day trade visit to China with Prime Minister Theresa May.
Mrs May, who is also accompanied by her husband Philip May and the Secretary of State for International Trade Liam Fox, is attempting “to build on the existing strong ties between our two countries”.
Among the chosen few business people invited to attend is on Neill Ricketts, the founder of graphene specialist Versarien and Gloucester MP Richard Graham.
Mr. Ricketts is also a member of the local enterprise partnership for Gloucestershire, GFirst LEP.

Spent last two days looking for the perfect site for NGA’s next conference this July in….Las Vegas. The location we had picked last year will not have the capacity we need so we had to get back to the drawing board. More info to come and look forward to seeing you all in Vegas!
