Co₃O₄ nanorods were prepared by a facile hydrothermal method. Eco-friendly deionized water rather than organic solvent was used as the hydrothermal media. The as-prepared Co₃O₄ nanorods are composed of many nanoparticles of 30-50 nm in diameter, forming a finger-like morphology. The Co₃O₄ electrode shows a specific capacitance of 265 F g-1 at 2 mV s-1 in a supercapacitor and delivers an initial...

Nanocrystalline La2Sn2O7 and La2Sn1.8Co0.2O7 with a phase-pure pyrochlore structure were synthesized by a hydrothermal method, and their catalytic activity was investigated for soot combustion. The as-synthesized catalysts presented relatively larger surface area, and pore volume, which was benefit to the gas molecule diffusion in the reaction. A uniform spherical structure with particle size o...

Films of crystalline WO(3) nanosheets oriented perpendicular to tungsten substrates were grown by a surfactant-free hydrothermal method, followed by sintering. The films exhibit photoelectrochemical oxygen evolution at low overpotential.

in the present work, the synthesis of barium hexaferrite (bafe12o19) nanoparticles in thepresence of a large excess amount of oh− anions by the hydrothermal method in the presence and absence of surfactants such as sodium dodecyl benzene sulfonate and triton x-114 was reported. the optimized temperature in the absence of surfactant was determined (200 °c) and then barium hexaferrite nanoparticl...

Nanocrystalline hydroxyapatite assembled hollow fibers (NHAHF) in the membrane form were fabricated by combining the electrospinning technique and the hydrothermal method. This novel hierarchical tubular structure of hydroxyapatite exhibited excellent protein loading capacity and long-term sustained release property.

Single-crystal tubular products on the millimetre scale have been synthesized from water-soluble calixarene and phenanthroline in the presence of lanthanides by a hydrothermal method, in which the extended structures contain some 1D infinite channels.

Impacts are common geologic features on the terrestrial planets throughout the solar system, and on at least Earth and Mars impacts have induced hydrothermal convection. Impact-generated hydrothermal systems have been suggested to possess the same life supporting capability as hydrothermal systems associated with volcanic activity. However, evidence of fossil microbial colonization in impact-ge...
