High-performance yet flexible micro-supercapacitors (MSCs) hold great promise as miniaturized power sources for increasing demand of integrated electronic devices. Herein, this study demonstrates a scalable fabrication multilayered graphene-based MSCs (MG-MSCs), by direct laser writing (DLW) stacked graphene films made from industry-scale chemical vapor deposition (CVD). Combining the dry transfer CVD films, DLW allows highly efficient large-areal with exceptional flexibility, diverse planar...
The paucity of proper sanitation facilities has contributed to the spread waterborne diseases in many developing countries. primary goal this study was demonstrate feasibility using a wastewater electrolysis cell (WEC) for toilet disinfection. treated designed reuse flushing and agricultural irrigation. Laboratory-scale electrochemical (EC) disinfection experiments were performed investigate efficiency WEC with four seeded microorganisms (Escherichia coli, Enterococcus, recombinant...
We have investigated electrochemical treatment of real domestic wastewater coupled with simultaneous production molecular H2 as useful byproduct. The electrolysis cells employ multilayer semiconductor anodes electroactive bismuth-doped TiO2 functionalities and stainless steel cathodes. DC-powered laboratory-scale experiments were performed under static anodic potentials (+2.2 or +3.0 V NHE) using samples, added chloride ion in variable concentrations. Greater than 95% reductions chemical...
The thermal conductivity (κ) of suspended graphene membranes made by chemical vapor deposition (CVD) was measured micro-Raman mapping. Cracks and wrinkles present in these were identified mapping, κ values their statistics obtained on free such imperfections a single Based this new technique, an average value 1875 ± 220 W m(-1) K(-1) at 420 K 26 that wrinkles, ~27% higher than the from 12 with wrinkles. These results suggest variation published for samples could, least part, be due to...
Recently, transition metal oxides (TMOs) mixed with carbon materials have attracted attention as lithium-ion battery (LIB) anode materials. However, the aggregation issue in TMOs hinders development of an ideal encapsulation structure In this paper, we report graphene reinforced MnO nanowires enhanced electrochemical performance LIB. The nanosheets (GNs)/MnO feature was confirmed by transmission electron microscopy, X-ray diffraction, Raman scattering, and photoelectron spectroscopy. GNs/MnO...
We demonstrate enhanced light–matter interactions in graphene–Au nanoparticle hybrid films and the application for high-quality SERS detection.
The interactions between visible light and sub-nanometer gaps were investigated by sandwiching graphene two layers of vertically stacked Au nanoparticles. optical properties such a hybrid film have been effectively tuned embedding monolayer graphene, enabling suppressed transmission ∼16% accompanied red-shift the resonant wavelength. Finite element simulations shown that strong coupling plasmonic nanoparticles leads to an electric field enhancement up 88 times in defined vertical gaps,...

Corrosion of metals in atmospheric environments is a worldwide problem industry and daily life. Traditional anticorrosion methods including sacrificial anodes or protective coatings have performance limitations. Here, we report atomically thin, polycrystalline few-layer graphene (FLG) grown by chemical vapor deposition as long-term coating film for copper (Cu). A six-year old, FLG-protected Cu visually shiny detailed material characterizations capture no sign oxidation. The success the...
Graphite oxide has become an important precursor for graphene oxide, reduced and a wide range of other graphene-based materials or composites. In numerous Hummers' methods the preparation graphite water is added to promote oxidization reaction but causes problems tedious purification liquid waste, which raises concerns environment processing cost in large-scale production oxide. Herein, we propose highly efficient chemical expandable (CEG) one-step while not during oxidization. This method...
