Microfluidic technologies have started to show their potential in assisting with the probes into the complicated mechanical-chemical interactions of multiphase fluids at microscale geometries (e.g., regular channels, porous media micromodels). The benefits of appropriately implementing microfluidics in such research efforts may include, but are not limited to: (1) small-dimensions facilitated analogous mechanical behaviors, (2) precise and reliable controls over relevant operating parameters of the fluids, (3) approximated reproduction of the hydrostatic or hydrodynamic circumstances, and (4) implementations of advanced visualization technologies such as microscopic imaging in order to reveal the dynamic processes involved in those multi-fluid interactions. Following the early studies on two-phase flow such as oil and water in microscale devices driven by the understanding of oil recovery process and mechanisms, carbon dioxide (CO2) has drawn increasing attention because of their...

Title: Responses of biological soil crust to and its relief effect on raindrop kinetic energy Author:Qin, Ning-Qiang; Zhao, Yun-Ge Subject:Ecosystem ; Rain ; Soil Microbiology ; Cyanobacteria -- Physiology ; Soil -- Analysis Description:
Based on the field investigation and by the method of simulated single-drop rain, this paper studied the responses of different types of biological soil crusts (biocrusts) in the wind-water erosion interleaving region of Loess Plateau to and their relief effect on the kinetic energy of raindrops. The responses of the biocrusts to raindrop kinetic energy had close relations with their biological composition. The cyanobacteria-dominated biocrusts with a thickness of 1 cm and the moss-dominated biocrusts with the coverage of 80% could resist in 0.99 J and 75.56 J of cumulative rain drop kinetic energy, respectively, and the potential resistance of the biocrusts with the same biological compositions was relative to the biomass of the biological compositions, i.e., the larger the biomass, the higher the resistance. As the chlorophyll a content of cyanobacteria- dominated biocrusts (which characterizes the cyanobacterial biomass) increased from 3.32 to 3.73 microg x g(-1), the resistance of the...
