We will need this forum to celebrate our big win with Zenyatta and enjoy a good laugh with all our detractors so worth keeping open.  

Optionsgal, I forgot about those hidden messages, they were a long time ago.

Enjoy the weekend everyone!

Some light reading for the weekend:

The capacitance performance of IC-RGO-15 was further validated using charging/discharging methods at 1.0 and 10.0 A g_1, and compared with T-RGO, as presented in Fig. 4A. Their specific capacitances were calculated to be 212 F g_1@1 A g_1 and 176 F g_1@ 10 A g_1 for IC-RGO, which were over twice higher than that of T-RGO (93 F g_1@1 A g_1 and 70 F g_1@ 10 A g_1). It is noteworthy that IC-RGO-15 possessed a higher capacitance compared with other 3D architectured graphene based nanomaterials reported in the literature.8c,15 The charging/ discharging stability of IC-RGO-15 was further evaluated. As shown in Fig. 4B, no decrease in capacitance was observed over the 5000 cycles @10 A g_1, confirming that IC-RGO exhibited excellent stability due to covalent linkages and its 3D interconnected superstructure.

In summary, we have demonstrated a new one-pot approach, which can effectively generate 3D interconnected reduced graphene oxide from graphite. It has several advantages, including (i) a significant amount of oxygen functional groups are removed from GO without the use of reducing agents; (ii) the interconnection is enabled by covalent linkages through the formation of ether as well as ester without the use of external linkers; (iii) the reduction and interconnection processes are rapid and simultaneous; and (iv) this process is facile, economical and easy to scale up for the mass production of 3D graphene superstructures. The produced IC-RGO represents a new type of 3D platform, which is promising for many graphene related applications such as sensors, catalysts, supercapacitors, batteries, adsorbents, and filters. For example, the fabricated IC-RGO exhibited a high capacitance with good charging and discharging stabilities due to covalent interconnections and a unique 3D superstructure. Overall, the new SHM and the novel IC-RGO developed in this study will facilitate the research and development of new types of 3D hybrids and functional graphene nanocomposites for promising energy and environmental applications.
