Nearly monodisperse cobalt ferrite (CoFe2O4) nanoparticles without any size-selection process have been prepared through an alluring method in an oleylamine/ethanol/water system. Well-defined nanospheres with an average size of 5.5 nm have been synthesized using metal chloride as the law materials and oleic amine as the capping agent, through a general liquid-solid-solution (LSS) process. Magne...

The utilization of renewable energy resources is desirable owing to several issues, including the depletion of petroleum resources and global warming1). Among many kinds of renewable resources, marine biomass (macroalgae) could be a promising feedstock for bioproduct and biofuel production2),3). However, appropriate pretreatment is needed prior to its effective utilization. Owing to the high wa...

Article history: Received 11 July 2012 Accepted 15 January 2013 Available online 7 February 2013 Editorial handling by Peter Birkle Groundwater chemistry and isotope data from 44 public supply wells in the Napa and Sonoma Valleys, California were determined to investigate mixing of relatively shallow groundwater with deeper hydrothermalfluids.Multivariate analyses includingCluster Analyses,Mult...

Geophysical observations and models provide important constraints on the properties of seafloor hydrothermal systems and associated fluxes. These studies indicate how the upper lithosphere is constructed and evolves, characteristics that are related to hydrothermal systems through the mechanical state of the lithosphere and the availability of heat to drive fluid flow. Geophysical studies illus...

Birnessite flower-like and α-type tubular MnO(2) nanostructures were selectively synthesized through simple decomposition of KMnO(4) under hydrochloric acid condition by controlling reaction temperature using a microwave-assisted hydrothermal method. The as-prepared samples were characterized in detail by various techniques including X-ray diffraction, field emission scanning electron microscop...

The CuO nano particles were synthesized from copper sulfate pentahydrate aqueous solution under the low hydrothermal condition at 80°C.The average crystallite size was calculated from De-Bye Scherrer’s equation. SEM/EDS,XRD were used to characterize the structure features of the product. FTIR spectra confirmed the adsorption of ammonia on the surface of the CuO nanoparticles. In addition, UV-vi...
