Abstract A simple hydrothermal technique was used to incorporate nanographene platelets (NGP) with CeO 2 /TiO composites different NGP contents. The prepared samples were then evaluated as a heterogeneous catalyst degrade methylene blue (MB) under visible light irradiation, ultrasonic and combination of the two. structural morphological properties /NGP investigated by X-ray diffraction (XRD). X...

Polyimide-graphene composites were synthesized by in-situ condensation polymerization and the thermal stability decomposition behavior of studied. Polyimides, because their aromatic backbone, are a class fire-retardant polymers. Their high char retention ≥50% at testing temperatures ≥600 °C makes them thermally stable The effect nanographene sheets on polyimide is presented in this paper. It sh...

We have derived a general rule for the appearance of zero-energy modes in super-chiral defective nanographene. This “super-zero-sum rule” defines zero new class materials, called polymerized phenalenyl-tessellation molecules (poly-PTMs). Through theoretical modeling electronic states these molecular forms, we provide concrete solutions achieving quantum-spin systems needed quantum-information d...
