Reduction Study of Oxidized Two-dimensional Graphene-based Materials by Chemical and Thermal Reduction Methods
… include high electrical conductivity, ballistic thermal conductivity, tensile strength exceeding that of steel, high flexural strength, optical transparency, and the ability to adsorb and desorb atoms and molecules. Due to the characteristics of said material, graphene is a candidate for …

Inquiry of Graphene Electronic Fabrication
… desired during graphene oxide deposit. Thermal reduction then reduces the graphene oxide into a purified state of graphene. Issues arise during thermal reduction because of excessive oxygen content in the furnace. The excess oxygen results in devices burning and additional oxidation of …

Solar thermochemical conversion of CO2 into fuels using Ni-Ferrite driven redox reactions: Thermodynamic efficiency analysis
… the inert gas flowrate lowers the required thermal reduction temperature, it also raises the total energy demand. On the other hand, enhancing gas-to-gas heat recuperation significantly decreases the energy demand associated with the process, thereby boosting overall efficiency. Overall, …

Interaction of Na, O₂, CO₂ and water on MnO(100): Modeling a complex mixed oxide system for thermochemical water splitting
… is highly desirable because it directly converts thermal energy into stored chemical energy in the form of hydrogen and oxygen. Recently, the Davis group at Caltech reported an innovative low-temperature (max 850°C) catalytic cycle for thermochemical water splitting based on sodium and manganese …

Materials and processes for the optical additive manufacturing of advanced organic/inorganic nanocomposites for the mask-less plating of insulator and semiconductor substrates, and microfluidic devices
… nanoparticles synthesized in situ via photo- and thermal reduction. Nanocomposites produced are rich in gold NPs and have interesting optical and plasmonic properties. Moreover, a fine tuning of the concentration of the gold salt allows the resin polymerization without suffering any inhibition of …
