Dunlop, Tiina Roose TITLE Stabilising Gold Nanoparticles for use in X-ray Computed Tomography Imaging of Soil Systems JOURNAL Royal Society Open Science This folder contains: - Experimental data including Uv-Vis data, ICP-MS data results and processed data from XCT images. - The files 'UvVis_MQ_Actual.mat' and 'UvVis_MQ_AuNP_Plotter.m' contains Uv-Vis data and plotting script for gold nanoparticles in ultrapure water (presented in figure 3). - The files 'UvVis_Coated_And_Uncoated_Actual.mat' and 'UvVis_Coated_And_Uncoated_AuNPs_Plotter.m' contains Uv-Vis data and plotting script for coated and non-coated nanoparticles in soil water solutions (presented in figure 4). - The files 'UvVis_SoilColumn_and_Oct_Data.mat' and 'UvVis_SoilColumn_and_Oct_Plotter.m' contains Uv-Vis data and plotting script for coated nanoparticles extracted from imaged and non-imaged soil columns (presented in figure 6). - The files 'A2S1M3_Data_Transposed.mat' and 'A2S1M3_Plotter_Transposed.m' contains grey value with depth data and plotting script for gold nanoarpticles in silica and/or alumina extracted from XCT images (presented in supplementary figure S2). - The Excel .xlsx file 'C_Scotson_Soil_Waters_Screen_06.04.17_1367_.xlsx' contains the ICP-MS data for the three soil water solutions (presented in Table 3). - Code for image processing of XCT data and mathematical modelling. - The ImageJ Macro code used to extract the the mean grey values with depth for the diffusion estimation model is given in the .ijm file 'Stack_Sub_Volume_Mean.ijm' Date of data collection: Jan-17 to Jan-19 Information about geographic location of data collection: University of Southampton, U.K.
