One‐Step Fabrication of Highly Transparent Superhydrophobic Coatings Via Atmospheric Pressure Radio Frequency Plasma Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Atmospheric‐pressure RF plasma deposition enables the fabrication of transparent, superhydrophobic coatings with anti‐reflective functionality. Process optimization yields high optical transmittance, robust environmental stability, and self‐cleaning properties.

The Value of Reducing Temporal Input Nonuniformities

open access: yesJournal of Agricultural and Resource Economics, 1992
The producer value of reducing temporal uncertainty concerning the level of soil nitrate is estimated for corn production in Iowa. The reduction in uncertainty is obtained through use of a late-spring nitrate test.

Soil compaction of peat under the influence of electrokinetic stabilization (EKS) treatment [PDF]

open access: yes, 2019
This study aims to enhance the properties of peat such as, (shear strength, compressibility, permeability and liquid limit). Peat is considered as one of the problematic soil in construction projects all over the world, which covers about 4% land of the ...

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]

open access: yes, 2012
To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

open access: yesAdvanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Development of a Sinkhole Raveling Chart Based on Cone Penetration Test (CPT) Data [PDF]

open access: yes, 2018
Naturally occurring sinkholes in Florida are formed when the soluble limestone bedrock weathers and creates cavities at its interface with the overburden finer-grained soils. The overburden soil then erodes into the limestone fissures, thus weakening the
