    The Effect of Aggregate-Forming Minerals on Thermodynamic Parameters Using Surface Free Energy Concept and Its Relationship with the Moisture Susceptibility of Asphalt Mixtures by Gholam Hossein Hamedi, Mohammad Reza Esmaeeli, Vahid Najafi Moghaddam Gilani, Seyed Mohsen Hosseinian

    Published 2021-01-01
    “…Therefore, the surface free energy (SFE) method, as one of the thermodynamic methods, and indirect tensile strength test (ITST) have been used to determine the failure mechanism and the rate of change of adhesion properties of asphalt mixtures under the influence of mineralogical characteristics. Prior to the above tests, an X-ray fluorescence spectrometry (XRF) test was performed to identify aggregate-forming minerals in eight different types of aggregates with various minerals from eight mines, and also the apparent bitumen film thickness was measured. …”

    Source and Ecological Risk Assessment of Potentially Toxic Metals in Urban Riverine Sediments Using Multivariate Analytical and Statistical Tools by Xiaojun Zheng, Abdul Rehman, Shan Zhong, Shah Faisal, Muhammad Mahroz Hussain, Syeda Urooj Fatima, Daolin Du

    Published 2024-12-01
    “…Additionally, techniques such as X-ray Diffraction (XRD) and Scanning Electron Microscopy–Energy Dispersive X-ray Spectroscopy (SEM-EDS) were employed to investigate the mineralogical and morphological aspects. The results indicated that mean concentrations (mg kg<sup>−1</sup>) of Cd (2.37), Cr (128), Hg (16.6), Pb (26.6), and Sb (2.44) were significantly higher than reference values given for upper continental crust (UCC) and world soil average (WSA), posing potential threats. …”

    Compaction of Hyaloclastite from the Active Geothermal System at Krafla Volcano, Iceland by Guðjón H. Eggertsson, Jackie E. Kendrick, Joshua Weaver, Paul A. Wallace, James E. P. Utley, John D. Bedford, Michael J. Allen, Sigurður H. Markússon, Richard H. Worden, Daniel R. Faulkner, Yan Lavallée

    Published 2020-01-01
    “…Thus, we conclude that compaction upon burial alone is insufficient to explain the physical and mechanical properties of the subsurface hyaloclastites present in the reservoir at Krafla volcano. Mineralogical alteration, quantified using SEM-EDS, is invoked to explain the further reduction of porosity and increase in strength of the hyaloclastite in the active geothermal system at Krafla.…”
