Experimental Study on Aging Oil Viscosity Reduction Caused by Ultrasound
Journal of Harbin University of Science and Technology, 2019 Aging oil usually performs large viscosity and poor liquidity，which make it difficult to transport effectively. In this paper, the aging oil is treated by ultrasonic wave, and the viscosity reduction effect is evaluated by measuring the viscosity curve ...

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces
Advanced Materials Interfaces, EarlyView.PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.
