Fluorescent nano-graphite oxides (NGO) with different size distribution were prepared via a one-pot hydrothermal route using ultrasmall graphite powder as starting material and subsequently separated using dialysis tubes with different molecular weight cutoff. The biomedical applications of these NGO for cell imaging were further investigated. Fourier transform infrared spectra demonstrated tha...

In this study, we reported the synthesis of the two-dimensional (2D) nanocomposite of molybdenum disulfide and nitrogen-doped graphene oxide (MoS2/nGO) as a platinum-free counter electrode (CE) for dye-sensitized solar cells (DSSCs). X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy were used to examine the characteristics o...

Two-dimensional graphene offers interesting electronic, thermal, and mechanical properties that are currently being explored for advanced electronics, membranes, and composites. Here we synthesize and explore the biological applications of nano-graphene oxide (NGO), i.e., single-layer graphene oxide sheets down to a few nanometers in lateral width. We develop functionalization chemistry in orde...

We develop an economic model of “greenwash,” in which a firm strategically discloses environmental information and a non-governmental organization (NGO) may audit and penalize the firm for engaging in greenwash. We identify conditions under which NGO punishment of greenwash backfires, inducing the firm to become less rather than more forthcoming about its environmental performance. We show that...
