ZERO GRAVITY-GRAPHENE FLIGHT -LOOP HEAT PIPES
In the past weeks, researchers in the Graphene Flagship tested the use of graphene as a light-propulsion material in solar sails, and as a smart coating in loop heat pipes for satellites in microgravity conditions, to simulate the extreme conditions in space.
In particular ISOF and IMM are involved in the loop heat pipe project together with partners at the Microgravity Research Centre, Université libre de Bruxelles, Belgium; the Cambridge Graphene Centre, University of Cambridge, UK and Leonardo Spa, Italy. Loop heat pipes are cooling systems in aerospace applications and satellites. Reserachers aim to prove that graphene can improve the performance of the heatpipe.
In order to test the proptptype in microgravity conditions, researchers took part in a low gravity parabolic flight operated by ESA in partnership with Novespace.

GRAPHENE WEEK 2017
Graphene week 2017, the longest running graphene and related material conference, now at is 12th edition, was held in Athens on 25-29 September. The event, organized jointly by the he Graphene Flagship and its partner FORTH (Foundation for Research and Technology Hellas), saw the participation of over 550 delagates from 39 different countries. Also CNR -ISOF took part at this event and Vincenzo Palermo officiated the opening cerimony.

NEW PAPER ON Small
The article " Dispersibility-Dependent Biodegradation of Graphene Oxide by Myeloperoxidase"
has been published on Small in collaboration with the Universities of Strasbourg and Castilla.
Understanding human health risk associated with the rapidly emerging graphene-based nanomaterials represents a great challenge because of the diversity of applications and the wide range of possible ways of exposure to this type of materials. Herein, the biodegradation of graphene oxide (GO) sheets is reported by using myeloperoxidase (hMPO) derived from human neutrophils in the presence of a low concentration of hydrogen peroxide. The degradation capability of the enzyme on three different GO samples containing different degree of oxidation on their graphenic lattice, leading to a variable dispersibility in aqueous media is compared. hMPO fails in degrading the most aggregated GO, but succeeds to completely metabolize highly dispersed GO samples. The spectroscopy and microscopy analyses provide unambiguous evidence for the key roles played by hydrophilicity, negative surface charge, and colloidal stability of the aqueous GO in their biodegradation by hMPO catalysis.
