Mobility of paramagnetic nanoparticles in porous media

Wang Y., Bagaria H., Zhang X., Johnson K., Abriola LM., Pennell KD., Tufts University, US

Stable paramagnetic nanoparticles were prepared and their mobility in reservoir matrix was measured as a function of particle mass loading, rate of sulfonate fraction in coating polymer, and the presence of surfactant.

Preparation and near infrared emission research of YBO3:Ce3+,Yb3+ nanosheets

Wang Y., Hu X., Zhan S., Zhang D., Zhang D., Fan J., Northwest University, CN

Y0.97Ce0.01Yb0.02BO3 nanosheets(a) and micro-rose(b) have the same hexagonal structure, and the intensity of (110) and (100) diffraction peaks of the sample a is stronger than b. Annealing the sample b in different temperature, the higher [...]
