Stabilization of Expansive Soil with Polyvinyl Alcohol and Potassium Carbonate

open access: yesAdvances in Civil Engineering, 2019
Expansive soils have great volume change potentials with water content changes, which is problematic to facilities. Great efforts have been spent on finding proper methods to stabilize expansive soils, but these stabilizers all had limitations.

Wedge Foundation in Expansive Soils

open access: yesEngineering and Technology Journal, 2009
The object of this study is to find a construction solution to the problem of expansive soils by suggesting of a new shape of the conventional footing which has a sharp edge, this footing is named a “wedge footing” which is considered as an alternative shape to the strip footing to dissipate the swelling pressure produced in the soil when inserting the

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

open access: yesAdvanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Hyperelastic Starch Hydrogel Configures Edible and Biodegradable All‐Components for Soft Robots

open access: yesAdvanced Science, EarlyView.
Hyperelastic starch hydrogel is tailored via a phase separation strategy of solvent‐antisolvent co‐modulation. The mechanical performance of starch hydrogel is widely tuned with maximum strains: 194.4–361.4%; maximum tensile stresses: 34–192 kPa; and Young's moduli: 36.0–205.8 kPa. Notably, the hydrogel achieves complete soil degradation within 24 days
