Abstract: A thermal analysis method based on inverse heat transfer is presented to estimate moisture content. The inverse method is based on experimental and numerical studies. A sand multilayer at different moisture contents is thermally excited. Thermocouple probes are placed at different positions in the thickness, and at the extremities of the multilayer, and record temperature variations during a test. A numerical heat transfer model associated with a parametric estimation algorithm allows layers’ moisture contents identification. Results are obtained thanks to previous tests that provide empirical relationships between the thermophysical properties and the moisture content

Abstract: This study focuses on the SO2 adsorption properties of graphene oxide fiber bundle. Graphene oxide fiber bundle was produced by NaOH reduction and Hummer’s method, and SO2 adsorption tests were carried out. According to the SEM analysis and EDS Spectra, sulphur particles accumulated on the surface of the graphene oxide fibers were observed, in along with the result of the EDS spectra showing 6.7% sulphur content on the graphene oxide fibers. The absorption was also 102 mg of SO2 per gram of sorbent (mg/gram) according to titration test.
