A new approach using graphene as a conductive binder in electrical supercapacitors has recently been produced. Graphene shows outstanding properties as a conductive binder, and can be used to replace...

This work explores the capacitance and ionic transport properties of size dependent graphene (from 100 nm to 1 μm) prepared through the liquid phase exfoliation of graphite in which the size of graphene was finely selected using a multi-step centrifugation technique.

There has been a great deal of interest in the electrochemical intercalation of two-dimensional materials in recent years, with studies of transition metal dichalcogenides (TMDs), a so-called “beyond graphene” material,...

We construct, in the work, chiral SU (3) Lagrangian with D mesons of spin J P = 0 − and J P = 1 − and charmed baryons of spin J P = 1/2 + and J P = 3/2 + . There are 42 leading two-body counterterms involving two charmed baryon fields and two D meson fields in the constructed Lagrangian.The heavy-quark spin symmetry leads to 35 sum rules while the large-N c operator analysis predicts 29 ones at the next-to leading order of 1/N c expansion. The combination of the sum rules from both the heavy-quark symmetry and the large-N c analysis results in 38 independent sum rules which reduces the number of free parameters in the chiral Lagrangian down to 4 only. This is a remarkable result demonstrating the consistency of the heavy-quark symmetry and large-N c operator analysis. * daris.sa@rmuti.ac.th : corresponding author
