Real-Time Behaviour of Dredged Slurry Treated by Air-Booster Vacuum Consolidation
Applied Sciences, 2023 The air-booster vacuum preloading method has been applied to slurry ground improvement. It is based on the conventional vacuum preloading method but with an additional injection of pressurised air into the soil via pre-installed conductors.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control
Advanced Materials, EarlyView.We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Study on drainage mechanism of complete path for vacuum preloading based on thermodynamics theory
Soils and FoundationsVacuum preloading has been a widely used consolidation method for soft clay ground improvement since the 1980s. Consolidation theory only explains the radial drainage process from soil to prefabricated vertical drains (PVD); however, the complete ...

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant
Advanced Materials Technologies, EarlyView.A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Analysis of Influence of Soft Ground Treatment by Vacuum Preloading on Adjacent Pile Foundation
Renmin Zhujiang, 2021 In soft ground,the deflection of adjacent pile foundation and the uneven settlement of soil around the piles caused by the surcharge loading is an extremely negative impact on the safety of the bridge.Base on the three-dimensional finite element analysis,
