Dataset for "Mix and measure - combining in situ X-ray powder diffraction and microtomography for accurate hydrating cement studies" paper
<p>Dataset for paper (doi: <a title="Persistent link using digital object identifier" href="https://doi.org/10.1016/j.cemconres.2023.107370" target="_blank" rel="noreferrer noopener">https://doi.org/10.1016/j.cemconres.2023.107370</a>) with the abstract: "It is reported an innovative methodology based on in situ MoKa1 laboratory X-ray powder diffraction (LXRPD) and microtomography (μCT) avoiding any sample conditioning. The pastes are injected in 2.0 mm capillaries and the extremes are just sealed. The measurements take place in the same region of the hydrating paste. Thick capillaries are key to avoiding self-desiccation, which dictates the need of high-energy X-ray radiation for the diffraction study. This approach has been tested with a PC 42.5 R paste having w/c=0.50. μCT data were collected at 12 hours and 1, 3, 7 and 79 days. LXRPD data were acquired at 1, 3, 7 and 77 days. In this proof-of-principle research, the same paste was also cured ex situ. Portlandite contents obtained by thermal analysis, ex situ powder diffraction, in situ mass balance calculation and in situ powder diffraction were 13.8, 13.1, 13.1 and 12.5 wt%, respectively. From the μCT study, the grey value histogram evolution with time showed a crossing point which allowed us to distinguish (appearing) hydrated products from (dissolving) unhydrated cement particles. Segmentations were carried out by global thresholding and the random forest approach (one type of supervised Machine Learning). The comparison of the segmented results for the unhydrated cement fraction and the Rietveld quantitative phase analysis outputs gave an agreement of 2%. The potential of this methodology to deal with more complex binders is also presented."</p>
Diffusely charged polymeric zwitterions as loosely hydrated marine antifouling coatings
<p>This dataset accompanies the article "Diffusely Charged Polymeric Zwitterions as Loosely Hydrated Marine Antifouling Coatings" by Shawn D. Mengel, Wen Guo, Guangyao Wu, John A. Finlay, Peter Allen, Anthony S. Clare, Riddhiman Medhi, Zhan Chen, Christopher K. Ober, and Rachel A. Segalman in Langmuir in 2023 (LINK). The article demonstrates that more diffusely charged polymeric zwitterions have improved surface hydration, which correlates with improved fouling resistance to <em>Ulva linza</em>. This dataset contains the necessary experimental data to reproduce the main text and supporting figures. Nuclear magnetic resonance spectra, vibrational sum frequency generation spectra, marine fouling assays, and contact angle measurements are included.</p>
Data from: Production of low-carbon amorphous precipitated silica and hydrated magnesium carbonate from olivine
<p>A novel process is reported that produces amorphous silica and nesquehonite (MgCO<sub>3</sub>.3H<sub>2</sub>O) from the magnesium silicate mineral olivine ((Mg,Fe)<sub>2</sub>.SiO<sub>4</sub>). The amorphous silica formed is a supplementary cementitious material (SCM) for use in concrete. The formation of nesquehonite sequesters carbon and means that the overall process is carbon negative. Nesquehonite can also be used to form low-carbon construction products such as bricks, blocks, and boards. This paper reports on key process optimisation studies. The potential for amorphous precipitated silica derived from olivine to produce carbon-negative concrete is discussed.</p>

Rietveld quantitative phase analysis of Oil Well Cement: in situ hydration study at 150 bars and 150ºC
<p>Raw data for: Rietveld Quantitative Phase Analysis of Oil Well Cement: In Situ Hydration Study at 150 Bars and 150 °C;</p> <p>doi: <a href="https://doi.org/10.3390/ma12121897">https://doi.org/10.3390/ma12121897</a></p> <p>Oil well cements are multimineral materials that hydrate under high pressure and temperature. Its overall reactivity at early ages is studied by a number of techniques including the consistometer. However, for a proper understanding of the performances of these cements in the field, the reactivity of every component, at the field conditions, must be analysed. So far, <em>in situ</em> high energy synchrotron powder diffraction studies of hydrating oil well cement pastes have been carried out but the quality of the data was not appropriated for Rietveld quantitative phase analyses. Therefore, the phase reactivities were followed by the inspection of the evolution of non-overlapped diffraction peaks. Very recently, we have developed a new cell specially designed to rotate under high pressure and temperature. Here, this spinning capillary cell is used to <em>in situ</em> study the hydration of a commercial oil well cement paste at 150 bars and 150 ºC. The powder diffraction data have been analysed by the Rietveld method to quantitatively determine the reactivities of each component phase. The reaction degree of alite was 90% after 7 hours and that of belite was 42% at 14 hours. These analyses are accurate as the <em>in situ</em> measured crystalline portlandite content at the end of the experiment, 12.9 wt%, compares relatively well with the value determined <em>ex situ</em> by thermal analysis, 14.0 wt%. The crystalline calcium silicates forming at 150 bars and 150 ºC are also discussed.</p>
Supplementary material for publication "Pore-scale salinity effects on methane hydrate dissociation" by Almenningen et al
<p>Supplementary materials for publication "Pore-scale salinity effects on methane hydrate dissociation"</p> <p>Abstract: Sedimentary methane gas hydrates may become a significant source of methane gas in the global energy mix for the next decades. The widespread distribution of methane hydrates, primarily in subsea sediments on continental margins, makes the crystalline compound attractive for countries with shorelines that seek self-sustainable energy. Fundamental understanding of pore-level methane hydrate distribution and dissociation pattern is important to anticipate the gas production from hydrate reservoirs. Especially the effect of local salinity gradients on dissociation characteristics must be understood as the aqueous phase in most reservoirs is saline. We evaluate the pore-level salinity effect on hydrate dissociation experimentally using silicon-wafer micro-models capable of withstanding high internal pressures. Methane hydrates were formed with brines for a range of salinities (0.0, 2.0, 3.5 and 5.0 wt% NaCl), and we study hydrate dissociation during both depressurization and thermal stimulation, which currently are the most cost-effective production methods. The laboratory results show how initial pore-scale hydrate distribution prior to dissociation affect the melting and mobilization of gas. The local pore-water salinities influenced the stability of the hydrate structure, and led to distinct dissociation patterns due to water freshening.</p>
