Surface-Sensitive Characterization of Nujol Interaction with CaCO3 (104) Surfaces Lanna I. M. Sinimbu, Jesana M. Loreto, Maria Luiza Dorneles, Igor Coelho, Emilia Annese, et al. Chemphyschem, 2026 In this study, we investigated the adsorption of Nujol, composed mainly of n‐dodecane molecules, on pristine and hydrated CaCO 3 (104) surfaces by atomic force microscopy (AFM), X‐ray photoelectron spectroscopy (XPS), and infrared reflection‐absorption spectroscopy (IRRAS). Our results reveal changes in the molecule–calcite interaction connected to differences in the substrate surface chemical composition upon hydration. XPS analysis suggests that the ideal pristine calcite forms a Ca 2+ ‐deficient surface under hydration as a consequence of the dissolution process, whose traces were identified in the AFM topography images. Upon Nujol adsorption, both interface's chemical composition and topography indicate the formation of a continuous versus a discontinuous film (several patches and 3D islands) on pristine and hydrated calcite surfaces, respectively. Finally, the IRRAS spectral analysis allowed us to correlate the distinct film's topography to a specific binding geometry of the molecule. These findings provide clear evidence of the modification of the hydrocarbon molecule–calcite interaction that is essential for optimizing key parameters (surface composition, surface hydration, and oil adhesion) to improve technologies related to wettability alteration, particularly in the field of oil recovery process.
Oil Removal in Prewet Calcite: Active Versus Inactive Ions Investigated by a Fourier Transform Infrared and X-ray Photoelectron Spectroscopy Study Jesana M. Loreto, Emilia Annese, L. G. Pedroni, Fernando Stavale Langmuir, 2025 In presalt reservoirs, natural rocks interact simultaneously with formation water (FW) and mineral oil. The prehydrated calcites with FW and demineralized water (DW) are suitable model systems to investigate oil adsorption (removal) on (from) their surfaces by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Preliminary characterization of the chemical composition of fresh cleaved calcite conditioned directly with low salinity (LS) waters, FW, and DW indicates that calcite undergoes (i) surface dissolution once in contact with DW and diluted LS water (LS100) as testified by the split of ν3 vibration bands of the CO32- group and (ii) partial chemical modification of calcite e through Mg incorporation, water anchoring at the surface, and salt deposit formation at the calcite/FW interface. Pristine and (FW, DW) prewet calcites were conditioned with Nujol, and an overall larger CH2 and CH3 vibration band intensity of Nujol was observed on the FW prehydrated surface than calcite/DW/oil and calcite/oil interfaces. The final conditioning of calcite/oil, calcite/FW/oil, and calcite/DW/oil with LS water ended up with greater oil removal for a saline solution of 0.2 mol/L ion strength, independent of the prehydration. Our results indicate that altered calcite chemical composition or dissolution affects subsequent oil adsorption and removal, and, therefore, there is a competitive role between brine ion strength and oil and surface compositions in the enhanced oil recovery process using LS water.
Laser-based angle-resolved photoemission spectroscopy with micrometer spatial resolution and detection of three-dimensional spin vector Takuma Iwata, T. Kousa, Y. Nishioka, K. Ohwada, K. Sumida, et al. Scientific Reports, 2024 We have developed a state-of-the-art apparatus for laser-based spin- and angle-resolved photoemission spectroscopy with micrometer spatial resolution (µ-SARPES). This equipment is realized by the combination of a high-resolution photoelectron spectrometer, a 6 eV laser with high photon flux that is focused down to a few micrometers, a high-precision sample stage control system, and a double very-low-energy-electron-diffraction spin detector. The setup achieves an energy resolution of 1.5 (5.5) meV without (with) the spin detection mode, compatible with a spatial resolution better than 10 µm. This enables us to probe both spatially-resolved electronic structures and vector information of spin polarization in three dimensions. The performance of µ-SARPES apparatus is demonstrated by presenting ARPES and SARPES results from topological insulators and Au photolithography patterns on a Si (001) substrate.
