Oxidative stress induced by cerium oxide nanoparticles in cultured BEAS-2B cells.
Cerium oxide nanoparticles of different sizes (15, 25, 30, 45 nm) were prepared by the supercritical synthesis method, and cytotoxicity was evaluated using cultured human lung epithelial cells… Expand
Characterization of cadmium removal from aqueous solution by biochar produced from a giant Miscanthus at different pyrolytic temperatures.
The objective of this study was to investigate the feasibility of biochar for removing Cd from aqueous solution. Biochars were produced from a Miscanthus sacchariflorus via slow pyrolysis at 300,… Expand

In this study, the potential harmful effect of cerium dioxide (CeO(2)), and titanium dioxide (TiO(2)) nanoparticles on the environment was investigated using Caenorhabditis elegans ecotoxicity tests.… Expand
Comparison of biochar properties from biomass residues produced by slow pyrolysis at 500°C.
Application of biochar from biomass pyrolysis to soil is gaining greater interest; this can ameliorate the soil quality, reduce fertilizer consumption, and sequestrate carbon. This study compares the… Expand
Slow pyrolysis of rice straw: analysis of products properties, carbon and energy yields.
Among many uses of rice straw, application of its biochar from pyrolysis to the soil is receiving greater interest for increased crop productivity and sequestration of CO2. This study investigated… Expand
Production and utilization of biochar: A review
Abstract Biochar produced during the thermochemical decomposition of biomass not only reduces the amount of carbon emitted into the atmosphere, but it is also an environment-friendly replacement for… Expand
The characteristics of bio-oil produced from the pyrolysis of three marine macroalgae.
The pyrolysis of two brown macroalgae (Undaria pinnatifida and Laminaria japonica) and one red macroalgae (Porphyra tenera) was investigated for the production of bio-oil within the temperature range… Expand
Bio-oil production from fast pyrolysis of waste furniture sawdust in a fluidized bed.
The amount of waste furniture generated in Korea was over 2.4 million tons in the past 3 years, which can be used for renewable energy or fuel feedstock production. Fast pyrolysis is available for… Expand
Pyrolysis characteristics and kinetics of oak trees using thermogravimetric analyzer and micro-tubing reactor.
In this work, pyrolysis characteristics were investigated using thermogravimetric analysis (TGA) at heating rates of 5-20 degrees C/min. Most of the materials were decomposed between 330 degrees C… Expand
