Microfiltration performance with two-phase flow
Published 2013“…The results showed that the effluent quality was better than the supernatant under the same gas flowrate, while membrane fouling was effectively mitigated by increasing gas flowrate due to the shear force generated by two-phase flow. In addition, the critical flux was observed to have a positive correlation with gas flowrate, which fitted well with the inertial lift model. …”

Tunable Mechanical Response of Self-Assembled Nanoparticle Superlattices
Published 2024“…Here, we perform in situ nanomechanical experiments that evidence up to an 11-fold increase in stiffness (∼1.49 to 16.9 GPa) and a 5-fold increase in strength (∼88 to 426 MPa) because of surface stiffening/strengthening from shaping these nanomaterials via focused-ion-beam milling. To predict the mechanical properties of shaped NPSLs, we present discrete element method (DEM) simulations and an analytical core-shell model that capture the FIB-induced stiffening response. …”
