Professor Yang Li's research lab specializes in multiphase flow dynamics, granular mechanics, and electrochemical materials science, with a focus on microscale fluid behavior in low-permeability reservoirs, advanced electrode design for nitrate conversion, and the mechanical response of granular soils using X-ray micro-CT and discrete element modeling. The lab integrates experimental techniques with high-fidelity simulations to investigate particle-scale mechanisms governing flow resistance, electrocatalytic performance, and soil fabric evolution under complex loading. Key research directions include non-spherical particle modeling, electrochemical reduction of pollutants, and the development of functional nanomaterials for environmental applications. The lab emphasizes interdisciplinary approaches combining materials science, geomechanics, and sustainable environmental technologies.

Take the flow characteristics of fluid in micro tube as the object, the characteristics of nonlinear filtration in low permeability reservoirs were studied using micro scale method by simulating the micro pore throat of reservoir with the micro tube which has the similar scale pore throat of low permeability reservoirs. The flow characteristics of de-ionized water flowing through fused silica capillary tubes with radius of 10.0 μm, 7.5 μm, 5.0 μm and 2.5 μm were investigated in experiments. Rela
Electrochemical reduction of nitrate to ammonia is of great interest in water treatment with regard to the conversion of contaminants to value-added products, which requires the development of advanced electrodes to achieve high selectivity, stability, and Faradaic efficiency (FE). Herein, nickel phthalocyanine was homogeneously doped into the fiber of a carbon nanotube (CNT) sponge, enabling the production of an electrode with high electrochemical double-layer capacitance (<i>C</i><sub>DL</sub>
This contribution provides high-fidelity images of real granular materials with the aid of X-ray micro-computed tomography (μCT), and employs a multi-sphere representation to reconstruct non-spherical particles. Through discrete-element method (DEM) simulations of granular samples composed of these non-spherical clumps, the effect of particle shape on the macroscopic mechanical response and microscopic soil fabric evolution is examined for soil assemblies under triaxial compression.
