The anaerobic digestion rate for flocculated sludge has been considered to be lower than that of original sludge, particularly in the later stages of digestion; attributed this relatively slower rate to the increased mass transfer resistance for reactants through the large flocs after flocculation. This study confirmed that methane production was retarded… (More)
We studied optimally-doped (Ba<sub>0.6</sub>K<sub>0.4</sub>)Fe<sub>2</sub>As<sub>2</sub> and LiFeAs by using ultrafast optical spectroscopy. Our temperature-dependent experimental results revealed that pseudogap exists above superconducting state in both materials.
FePt nanoparticles (NPs) have recently been revealed to be significant multifunctional materials for the applications of biomedical imaging, drug delivery and magnetic hyperthermia due to their novel magnetic properties. In this study, a newly discovered photothermal effect activated by the near infrared (NIR) femtosecond laser for FePt NPs was… (More)
We demonstrated ultrafast acoustic phonon spectroscopy up to 1.5 THz, and measured the acoustic signals up to 1 THz after they travelled through silica. Acoustic properties of silica films were characterized in sub-THz regime.
