A novel chemical synthesis method has been developed to directly graft graphene quantum dots (GQDs) onto carbon fibre (CF) in-situ via covalent ester linkages at low temperature (90°C). SEM and TEM images depict the grafting of GQDs on CF showing about 75% of the GQD falls below 40nm. The grafting was further confirmed by FTIR, RAMAN, XPS and XRD spectroscopy. The flexible fabric supercapacitor manufactured...
This paper reports a Cellular Automata Machine (CAM) as a general purpose pattern recognizer. The CAM is designed around a general class of CA known as Generalized Multiple Attractor Cellular Automata (GMACA). Experimental results confirm that the sparse network of CAM is more powerful than conventional dense network of Hopfield Net for memorizing unbiased patterns.
A novel chemical method was developed to graft carbon nanotubes (CNTs) onto carbon fiber (CF) by direct covalent bonding to form a CNT–CF hierarchical reinforcing structure. The grafting via ester linkage (formed at a low temperature of 70 °C without using any contaminating catalyst or coupling agent) was evidenced by SEM, FTIR, RAMAN, XPS and XRD spectroscopy. The CNT failure stress obtained from...
