A coal-tar-derived mesophase was chemically activated to produce a high surface area (~3200 m(2)/g) carbon with a porosity made up of both micropores and mesopores. Its adsorption capacities were found to be among the highest ever reported in literature, reaching values of 860 mg/g and 1200 mg/g for the adsorption of benzene and toluene, respectively, and(More)
This study deals with the adsorption of Cr(VI) from synthetic and industrial wastewater, produced by a sewage plant. The activated carbons were prepared from a lignocellulosic raw material by thermal treatment at 450 and 650 degrees C in the presence of acid (AlCl(3), HCl, H(3)PO(4) and H(2)SO(4)) and base (NaOH) agents. To optimize the adsorption of(More)
We prepared a series of graphene-like materials by thermal exfoliation/reduction of a graphite oxide (GO) at temperatures between 127oC and 2400oC. The extent of the exfoliation and reduction of the GO at different temperatures, as well as the impact on the resultant graphene-like materials (TRGs), were studied through their chemical/structural(More)
Two graphene-like materials, obtained by thermal exfoliation and reduction of a graphite oxide at 700 and 1000oC, were studied as active electrodes in the positive half-cell of a Vanadium Redox Flow Battery (VRFB). In particular, that obtained at 1000oC exhibited an outstanding electrochemical performance in terms of peak current densities (30.54 and 30.05(More)
Rotation curves of spiral galaxies are known with reasonable precision for a large number of galaxies with similar morphologies. The data implies that non-Keplerian fall–off is seen. This implies that (i) large amounts of dark matter must exist at galactic scales or (ii) that Newtonian gravity must somehow be corrected. We present a method for inverting the(More)
Graphene materials with different characteristics in terms of sheet size and defects (structural and/or functional groups) were obtained by the reduction with hydrazine of two graphene oxides with similar oxygen content but with functional groups of different type and location. The oxides were prepared from two synthetic graphites with distinct crystalline(More)
The growing interest in supercapacitors (SCs), also called electrochemical capacitors or ultracapacitors, is due to their high power density, long cycle life, short charging time and good safety record. These factors make them highly attractive for use in electric devices and in electric vehicles. For such applications it is first necessary to increase the(More)
A pyrolysis product derived from SASOL-Lurgi gasifier pitch was activated using different proportions of KOH. The increase of the amount of KOH used for activation caused the activation degree of the carbons to increase very significantly. The activated carbons obtained using lower amounts of KOH were mainly microporous, while the amount of mesopores(More)
OBJECTIVE The aim of this study is to provide long-term data on the effectiveness and safety of olanzapine in a group of patients with severe refractory schizophrenia. GENERAL METHODS Twenty patients who had previously received treatment with typical antipsychotic agents and who met the DSM-IV criteria of schizophrenia and refractoriness to treatment were(More)
The effect of the parent graphite on the structure of graphene oxide (GO) is investigated using high purity graphites with a uniform crystallite size. Our results provide direct evidence of how the size of the graphite crystal affects the oxidation process and the functionality and sheet size of the resulting GO. The important role of the crystal boundaries(More)
