Abstract: A method of producing pristine graphene particles through a one-step, gas-phase, catalyst-free detonation of a mixture of one or more carbon-containing compounds hydrocarbon compounds and one or more oxidizing agents is provided. The detonation reaction occurs very quickly and at relatively high temperature, greater than 3000 K, to generate graphene nanosheets that can be recovered from the reaction vessel, such as in the form of an aerosol. The graphene nanosheets may be stacked in single, double, or triple layers, for example, and may have an average particle size of between about 35 to about 250 nm.

Abstract: The synthesis of layered free-standing papers, films, tapes, and painted coatings. composed of acid-functionalized, few-layer molybdenum disulfide (MoS2) and reduced graphene oxide (rGO) flakes for use as a binder-free conducting electrode in NIB applications are described. The mechanical and electrochemical performance of the layered free-standing papers is also described. Synthesis was achieved through vacuum filtration of highly homogenous dispersions comprising varying weight percentages of exfoliated MoS2 flakes in graphene oxide in DI water, followed by thermal reduction. The electrochemical behavior of the composite paper was evaluated as a counter electrode against pure Na foil in a half-cell configuration. In addition, the unaxial tensile testing of the composite papers demonstrated their exceptionally high fracture strength.

Abstract: Tricyclic pyrone compounds having high oral bioavailability, excellent blood-brain barrier permeability, and low toxicity are presented. Administration of the compounds to Alzheimer's Disease transgenic models resulted in substantially reduced soluble and insoluble Aβ species in the brain without affecting general behavior and motor coordination. Furthermore, in addition to blocking the toxicity and formation of both intraneuronal and extracellular Aβ aggregates, the compounds also increase cellular cholesterol efflux, restore axonal trafficking, and enhance hippocampal synaptic plasticity.

Abstract: The invention generally related to a method for preparing a layer of graphene directly on the surface of a semiconductor substrate. The method includes forming a carbon-containing layer on a front surface of a semiconductor substrate and depositing a metal film on the carbon layer. A thermal cycle degrades the carbon-containing layer, which forms graphene directly upon the semiconductor substrate upon cooling. In some embodiments, the carbon source is a carbon-containing gas, and the thermal cycle causes diffusion of carbon atoms into the metal film, which, upon cooling, segregate and precipitate into a layer of graphene directly on the semiconductor substrate.
