Graphene nanosheets have been generated in the confined space of the two-dimensional galleries of a layered double hydroxide (LDH) and good control over the number of graphene layers can be achieved by adjusting the amounts of intercalated carbon source.

Inspired by interfacial interactions of protein matrix and the crystal platelets in nacre, herein, a supertough artificial nacre was produced through constructing the synergistic interface interactions of p-p interaction and hydrogen bonding between graphene oxide (GO) nanosheets and sulfonated styreneethylene/butylene-styrene copolymer synthesized with multifunctional benzene. The resultant GO...

The design and synthesis of efficient electrocatalysts for hydrogen evolution reaction under all pH conditions is extremely desirable but still remains a challenge. Here a facile method to decorate PdTe nanowires on reduced graphene oxide nanosheets (PdTe NWs/rGO) has been developed. As a robust integrated 2D hydrogen-evolving cathode catalyst, the Pd3.02Te NWs/rGO shows a low onset potential o...

Highly-dispersed Ru nanoparticles were grown on graphene nanosheets by simultaneously reducing graphene oxide and Ru ions using ethylene glycol (EG), and the resultant Ru/graphene nanocomposites were applied as a catalyst to ammonia decomposition for COx-free hydrogen production. Tuning the microstructures of Ru/graphene nanocomposites was easily accomplished in terms of Ru particle size, morph...

Atmospheric pressure plasma jet (APPJ) technology is a versatile technology that has been applied in many energy harvesting and storage devices. This feature article provides an overview of the advances in APPJ technology and its application to solar cells and batteries. The ultrafast APPJ sintering of nanoporous oxides and 3D reduced graphene oxide nanosheets with accompanying optical emission...

Graphene oxide (GO) nanosheets and polyoxometalate such as H(3)PW(12)O(40) (PTA) are prepared into a multilayer film via a layer-by-layer inkjet printing method. The GO/PTA composite thin film shows linear, uniform and regular layer-by-layer growth. Under UV-irradiation, a photoreduction reaction takes place in the film which converts GO to reduced GO (rGO) due to the photoreduction activity of...

We demonstrate a universal approach to extract one- and two-dimensional nanomaterials from contaminated water, which is based on a microscopic oil-water interface trapping mechanism. Results indicate that carbon nanotubes, graphene, boron nitride nanotubes, boron nitride nanosheets, and zinc oxide nanowires can be successfully extracted from contaminated water at a successful rate of nearly 100...

High-performance microfibers such as carbon fibers are widely used in aircraft and wind turbine blades. Well-aligned, strong microfibers prepared by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers are designed here for the first time and have the potential to supersede carbon fibers due to their low cost. These well...

Cobalt oxides, such as Co3O4 and CoO, have received increased attention as potential anode materials for rechargeable lithium-ion batteries (LIBs) owing to their high theoretical capacity. Nanostructure engineering has been demonstrated as an effective approach to improve the electrochemical performance of electrode materials for LIBs. In this review, we summarize recent development in the rati...

Hybrid organic aerogels consisting of polyvinyl alcohol (PVA), cellulose nanofibrils (CNFs), and graphene oxide nanosheets (GONSs) were prepared using an environmentally friendly freeze-drying process. The material properties of these fabricated aerogels were measured and analyzed using various characterization techniques including compression testing, scanning electron microscopy, thermogravim...
