The influence of suction changes on the stiffness of railway formation

, 2011
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Crack and size-dependence of shear modulus in a drying particulate film

, 2012
We utilized controlled vertical drying deposition (CVDD) method, which can fabricate a uniform face-center-cubic (FCC) structure film, to investigate the crack formation and the size dependence of shear modulus in a drying particulate film. We found that

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
