    The Mobility Incubator Program has recently been launched in the Latvian capital, Riga. Organized by the European Institute of Innovation and Technology, the scheme aims to further develop innovative mobility prototypes in real-time. If successful following this initial stage the prototypes will act to raise the living standard of city residents and serve as an attractive prospect for potential investors, being implemented on a wider scale.

    The teams and their prototypes:

    The projects were developed over a period of 10 weeks following the 48-hour mobility hackathon in April. The six pilot projects are as follows:

    • The Mikropoint team – A new mobility point in Zemitana Square, combining a shed for electric scooters and bicycles, a mini bicycle workshop, and bench. Aims to increase the mobility network for environmentally friendly vehicles.
    • The getUgo team – Remote control of autonomous vehicles, machines and other devices with a teleoperation software and hardware platform.
    • The E-Stop team – Offers a solution for storing and charging e-scooters within the Alfa shopping centre.
    • The electrify team – Promotion of electromobility by offering electric minibuses for passenger transport (still under development).
    • The “Velorūme” team – Offers bicycle storage the size of a single parking spot.
    • The Simplecharge – Encouraging the use of street lighting poles to charge electric vehicles.
  2. 14th edition of International Design Awards

    In 2019, the ingenious Belgian “Cycling through the trees”, realized in Hechtel-Eksel, won gold in one of the architecture categories at the International Design Awards (IDA) in Los Angeles, USA. It was a beautiful promo for Tourism Limburg, that commissioned the project and a huge reward for  the designers, BuroLandschap, Atelier Ensemble and De Gregorio & Partners.

    If you want to follow in their footsteps, now is the time to submit your entry for the 2020 edition. IDA is always looking for visionary, iconic designs in product design, fashion, graphic design, interior design and architecture. A 19-member jury of experts from all over the world decides who receives the awards. The criteria are diverse: aesthetics and functionality, durability, innovative content, ergonomics, etc.

    All further details are on the IDA website

  3. Environmentally-friendly graphene bio-inks for rechargeable batteries and energy storage devices

    Source ​Letizia Diamante @ Graphene Flagship – Researchers at Graphene Flagship partners Trinity College Dublin, Ireland, CIC EnergiGUNE and INCAR-CSIC, Spain, have produced rechargeable batteries and energy storage devices made of a non-toxic and environmentally friendly graphene-based material.

    With current metal-ion batteries reaching their theoretical limitations in terms of cycle life, capacity and power, researchers focused on metal-air alternatives, such as sodium-air (Na-O2) batteries. Equipped with sodium anodes and oxygen-trapping cathodes, these devices have interesting and unique rechargeable capabilities: NaOis produced when the battery drains its stored energy, which is then recycled back to form metallic sodium and oxygen when the battery charges.

    In this study, a cathode was made using a porous graphene-based aerogel. The Graphene Flagship team fabricated it by electrochemically exfoliating graphite foils with the help of molecules derived from DNA building blocks, such as adenosine monophosphate. These biomolecules insert into the graphite structure, causing the foils to swell. The foils are then scraped off and processed further, resulting in the formation of graphene flakes, around 1-2 nm in thickness and 400-600 nm in width.

    The Graphene Flagship researchers also highlighted a secondary function of these biomolecules: they are adsorbed on the surface of graphene, allowing the flakes to be dispersed in water. The resulting conductive ink is preferable over others that contain organic solvents for several reasons – above all, due to its low impact on the environment. The Graphene Flagship researchers then used a freeze-drying technique to transform the ink into an aerogel, suitable for the battery’s cathode. These new batteries could be recharged 50 times with an efficiency of 94%, which is a very competitive result that out-performs other graphene-based cathodes.

    We believe that the phosphates in these biomolecules are the main reason for this success. These chemical groups allow NaO2 to be recycled more quickly during the charging phase,” explains Nagore Ortiz-Vitoriano, from Graphene Flagship partner CIC EnergiGUNE, who co-authored this study.

    With no need for any additives, this graphene ink was also used for printing electrically conductive patterns as part of storage devices, such as micro-supercapacitors. These devices showed a remarkable performance, comparable to the current graphene-based devices, and retained around 75% of the initial performance after 5,000 charge/discharge cycles.

    We will keep refining the structure of our devices and continue to improve their capacity and cycle life, as well as reducing the energy losses during operation,” says Jose Maria Munuera, from Graphene Flagship partner CSIC, and corresponding author of this study.

    By demonstrating that an aqueous graphene-based bio-ink improves the performances of batteries and supercapacitors, this work provides a novel sustainable material solution to advance the field,” comments Vittorio Pellegrini, the Graphene Flagship’s Work Package Leader for Energy Storage.

    Andrea C. Ferrari, Science and Technology Officer of the Graphene Flagship and Chair of its Management Panel, adds: “Meeting the sustainable development goals is at the core of the Graphene Flagship science and innovation. Energy applications are amongst the promising impact areas for graphene and related materials. This works shows a sustainable approach for the production of graphene to be used in re-chargeable batteries, with a double advantage for the environment.
