Recent trends in the applications of thermally expanded graphite for energy storage and sensors - a review.

Carbon nanomaterials such as carbon dots (0D), carbon nanotubes (1D), graphene (2D), and graphite (3D) have been exploited as electrode materials for various applications because of their high active surface area, thermal conductivity, high chemical stability and easy availability. In addition, due to the strong affinity between carbon nanomaterials and various catalysts, they can easily form metal carbides (examples: ionic, covalent, interstitial and intermediate transition metal carbides) and also help in the stable dispersion of catalysts on the surface of carbon nanomaterials. Thermally expanded graphite (TEG) is a vermicular-structured carbon material that can be prepared by heating expandable graphite up to 1150 °C using a muffle or tubular furnace.

Barrier-assisted vapor phase CVD of large-area MoS monolayers with high spatial homogeneity.

Atomically thin molybdenum disulphide (MoS) is a direct band gap semiconductor with negatively charged trions and stable excitons in striking contrast to the wonder material graphene. While large-area growth of MoS can be readily achieved by gas-phase chemical vapor deposition (CVD), growth of continuous MoS atomic layers with good homogeneity is indeed one of the major challenges in vapor-phase CVD involving all-solid precursors. In this study, we demonstrate the growth of large-area continuous single crystal MoS monolayers on -plane sapphire by carefully positioning the substrate using a facile staircase-like barrier.
