Study on the Shear Characteristics of the Frozen Soil–Concrete Interface at Different Roughness Levels

Buildings
The shear characteristics of the frozen soil–concrete interface are core parameters in frost heave resistance design in cold-region engineering, and the influence mechanism of interface roughness on these characteristics is not clear.

Collusion and Durability [PDF]

We make the observation that cartels which produce goods with lower durability are easier to sustain implicitly. This observation generates the following results: 1) implicit cartels have an incentive to produce goods with an inefficiently low level of ...

Impact of Structural Adhesive Hybridization Strategy on the Performance of In‐Mold Electronics Devices Across Thermoforming and Injection Molding

Advanced Engineering Materials, EarlyView.
In‐mold electronics (IME) undergo complex thermoforming and over‐molding processes that strain device integrity. This study demonstrates how adapting the amount and placement of structural adhesive to local deformation levels preserves electrical functionality.

An Empirical Model for Optimal Highway Durability in Cold Regions [PDF]

, 2016
We develop an empirical tool to estimate optimal highway durability in cold regions. To test the model, we assemble a data set containing all highway construction and maintenance projects in Arizona and Washington State from 1990 to 2014.

Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers

Advanced Engineering Materials, EarlyView.
Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

Ultrasonic Atomization Spray Coating of PCL on an Mg‐Based Alloy Enhanced by Plasma Electrolytic Oxidation for Improved Adhesion, Corrosion Resistance, and Biocompatibility

Advanced Engineering Materials, EarlyView.
Plasma electrolytic oxidation is combined with ultrasonic spray deposition of polycaprolactone (PCL) on WE43 magnesium alloy to improve adhesion, corrosion resistance, and cytocompatibility. The hybrid coating demonstrates significantly reduced hydrogen evolution and enhances mechanical bonding, offering a promising strategy for next‐generation ...
