Insights into the Interfacial Contact and Charge Transport of Gas-Sensing Liquid Metal Marbles

ACS Applied Materials & Interfaces, 2022
Understanding the interfacial contacts between liquid metals and substrate materials is becoming increasingly important for the fast-rising liquid metal-enabled technologies. However, for such technologies, probing the contact behavior and interfacial charge transport has remained challenging due to the deformable nature of liquid metals and the ...

Liquid marble for gas sensing

Chemical Communications, 2010
The porous and superhydrophobic shell of a liquid marble prevents contact of its liquid core with outside surfaces, but allows gas transport. Liquid marble can therefore be used to sense gas or emit gas. Liquid marbles loaded with different indicators can simultaneously sense different gases via different mechanisms.

CO₂-Gas-Responsive Liquid Marble

Langmuir, 2019
Liquid marbles were prepared using a water droplet and nonprotonated hydrophobic poly(2-N,N-diisopropylaminoethyl methacrylate) (PDiPAEMA) powder. Although the nonprotonated PDiPAEMA was hydrophobic, PDiPAEMA became hydrophilic because of the protonation of the pendant tertiary amino groups under acidic conditions.

Porous liquid marble shell offers possibilities for gas detection and gas reactions

Chemical Engineering Journal, 2010
Abstract The hydrophobic shell of a liquid marble prevents direct contact of the liquid core of the marble with any condensed phases (i.e. solid or liquid) outside the marble, but allows gas and vapour to diffuse across the shell. This property of a liquid marble naturally enables it to discriminately absorb or emit gaseous and vaporous compounds ...

New gas chromatographic instrumentation for studying the action of sulfur dioxide on marbles

Journal of Chromatography A, 2005
Reversed-flow gas chromatography, which is a sub-technique of inverse gas chromatography, is an experimental arrangement simulating a simple model for the action of air pollutants on buildings and monuments, in laboratory scale. By using a commercial gas chromatograph and an appropriate mathematical analysis, kinetic parameters such as rate constants ...

Gas Permeability Evolution with Deformation and Cracking Process in a White Marble Under Compression

Transport in Porous Media, 2015
This paper presents an experimental study on the gas permeability evolution with deformation and cracking process in a white marble under compressive stresses. Uniaxial and triaxial compression tests with different confining pressures are firstly carried out to generate different states of deformation and induced cracks.

Kinetic study of reactivity of marble with sulphur dioxide by reversed-flow gas chromatography

Journal of Chromatography A, 1987
Abstract Reversed-flow gas chromatography was used to study the kinetics of the action of sulphur dioxide (SO2) on calcium carbonate (CaCO3) and to draw some conclusions about the mechanism of the phenomenon and its rate-determining step. SO2 was fed to the solid by gaseous diffusion at constant temperature, using a short diffusion column, either ...

Characterization of Polymeric Coatings in Terms of Their Ability to Protect Marbles and Clays against Corrosion from Sulfur Dioxide by Inverse Gas Chromatography

International Journal of Polymer Analysis and Characterization, 2013
The protective performance of polymeric coatings was tested on marble and clays against their corrosion from sulfur dioxide. The method used was reversed-flow gas chromatography, which allowed us to determine deposition velocities (V d ), total effective diffusion coefficients (D y ), and local adsorbed equilibrium concentrations of SO2 on marbles and ...
