Investigation of the microcantilevers by the photoacoustic elastic bending method
(Institute of Electrical and Electronics Engineers Inc., 2014)
The amplitude of the photoacoustic (PA) elastic bending signals vs. the modulation frequency of the excitation optical beam for the chip with Si cantilevers were measured and analyzed. The experimental PA elastic bending ...
Leaching of Arsenic from Tailings by Microbially Produced Rhamnolipids
(Japan Society for Environmental Chemistry, 2014)
The focus of this study was to determine influence of microbial surfactants rhamnolipids on mobilization of heavy metals from the tailings and to estimate the use of rhamnolipids, as washing agents in pretreatment of metal ...
