Data and results for manuscript "Multi-frequency electrical impedance tomography as a non-invasive tool to characterize and monitor crop root systems "
<p>Root systems are essential in nutrient uptake and translocation, but are difficult to characterize non-invasively with existing methods. We propose electrical impedance tomography (EIT) as a new tool for the imaging and monitoring of crop root systems. In a laboratory experiment we demonstrate the capability of the method to capture physiological responses of root systems with high spatial and temporal resolution. We conclude that EIT is a promising functional imaging technique for crop roots.</p> <p>This package contains measured raw EIT data, electrical imaging results, spectral results from the Debye decomposition, and the Python scripts used to generate the plots in the manuscript.</p>

Data and results for manuscript "Flow dynamics in hyper-saline aquifers: hydro-geophysical monitoring and modeling"
<p>The paper presents a general methodology that will help understand how freshwater and saltwater may interact in natural porous media, with a particular view at practical applications such as the storage of freshwater underground in critical areas such as semi-arid zones around the Mediterranean sea. The methodology is applied to a case study in Sardinia and shows how a mix of advanced monitoring and mathematical modeling tremendously advance our understanding of these systems.</p> <p>This package contains the raw cross-hole time-lapse ERT data, additional field data, the ERT inversion results of the field data as well as the modeling data in terms of the concentration distribution of the density-dependent flow and transport model and the inverted synthetic ERT monitoring results.</p>

Calculated state-of-the art results for solvation and ionization energies of thousands of organic molecules relevant to battery design
<p>This dataset presents molecular properties critical for battery electrolyte design, specifically solvation energies, ionization potentials, and electron affinities. The dataset is intended for use in machine learning model testing and algorithm validation. The properties calculated include solvation energies using the COSMO-RS method [1] and ionization potentials and electron affinities using various high-accuracy computational methods as implemented in MOLPRO [2]. Computational details can be found in Ref. [3], with scripts used to generate the data mostly uploaded to our github repository [4].</p> <p>Molecular Datasets Considered:</p> <ul> <li> <p>QM9 Dataset: Contains small organic molecules broadly relevant for quantum chemistry [5]</p> </li> <li> <p>Electrolyte Genome Project (EGP): Focuses on materials relevant to electrolytes.[6]</p> </li> <li> <p>GDB17 and ZINC databases: Offer a broad chemical diversity with potential application in battery technologies.

They are structured differently as amon entries are sorted by the number of heavy atoms in the amon (e.g., all amons with 3 heavy atoms are stored in <code>ni3</code>). Because of the large number of amons with 6 or 7 heavy atoms,they are further split into <code>ni6_1</code>, <code>ni6_2</code>, and so on. A sub dictionary of an amon dictionary or a full molecule dictionary contains the following keys:</p> <p><code>ECFP</code> - ECFP4 representation vector</p> <p><code>SMILES</code> - SMILES string</p> <p><code>SYMBOLS</code> - atomic symbols</p> <p><code>COORDS</code> - atomic positions in Angstrom</p> <p><code>ATOMIZATION</code> - atomization energy in [kcal/mol]</p> <p><code>DIPOLE</code> - dipole moment in Debye</p> <p><code>ENERGY</code> - energy in Hartree</p> <p><code>SOLVATION</code> - solvation energy in [kcal/mol] for different solvents at 300 K.</p> <p> </p> <p>Files:</p> <p> </p> <p><strong><em><code>GDB17.json.zip</code> </em></strong>(unpack with unzip first with unzip <strong><em><code>GDB17.json.zip</code></em></strong>) - subset of GDB17 random molecules</p> <p><strong><em><code>AMONS_ZINC.json</code> </em></strong>-<strong><em> </em></strong>all<strong><em> </em></strong>amons of ZINC up to 7 heavy atoms</p> <p><strong><em><code>EGP.json</code> </em></strong>- EGP molecules</p> <p><code><strong><em>AMONS_GDB17.json</em></strong></code> - all amons of GDB17 up to 7 heavy atoms</p> <p><code><strong>QM9IPEA_raw_molpro_output</strong>.zip</code> - compressed folder with raw Molpro input and output files</p> <table> <tbody> <tr> <td><strong>File Name</strong></td> <td><strong>Description </strong></td> <td><strong>Molecules</strong></td> </tr> <tr> <td>AMONS_GDB17.json</td> <td>GDB17 amons</td> <td>37860</td> </tr> <tr> <td>AMONS_ZINC.json</td> <td>ZINC amons </td> <td>88771</td> </tr> <tr> <td>GDB17.json</td> <td>Subset of GDB17</td> <td>309468</td> </tr> <tr> <td>EGP.json </td> <td>EGP molecules </td> <td>18362</td> </tr> </tbody> </table> <p>Atomic energies $E_{at}$ at BP and def2-TZVPD level in Hartree [Ha]</p> <table> <tbody> <tr> <td><strong>Element</strong></td> <td><strong>H</strong></td> <td><strong>C</strong></td> <td><strong>N</strong></td> <td><strong>O</strong></td> <td><strong>F</strong></td> <td><strong>Br</strong></td> <td><strong>Cl</strong></td> <td><strong>S</strong></td> <td><strong>P</strong></td> </tr> <tr> <td>Eat [Ha]</td> <td>-0.5</td> <td> -37.85</td> <td> -54.60</td> <td> -75.09</td> <td>-99.77</td> <td>-2574.40</td> <td> -460.20</td> <td> -398.16</td> <td>-341.30</td> </tr> </tbody> </table> <p> </p> <table> <tbody> <tr> <td><strong>B</strong></td> <td><strong>Si</strong></td> </tr> <tr> <td> -24.65</td> <td> -289.40</td> </tr> </tbody> </table> <p>We follow the convention of negative atomization energies for stablity compared to the isolated atoms:</p> <p>$E_{atomization} = E_{mol} - \sum_{i} E_{at,i}$</p> <p><br>Free energy of solvation at 300 K in [kcal/mol]:</p> <h3>Ionization potentials and electron affinities</h3> <p>The upload contains two JSON files, <strong><em>QM9IPEA.json</em></strong> and <strong><em>QM9IPEA_atom_ens.json</em></strong>. <strong><em>QM9IPEA.json </em></strong>summarizes MOLPRO calculation data grouping it along the following dictionary keys:</p> <p> </p> <p><strong>QM9IPEA.json</strong></p> <p><code>COORDS</code> atom coordinates in Angstroms<br><code>SYMBOLS</code> atom element symbols<br><code>ENERGY</code> total energies for each charge (0, -1, 1) and method considered<br><code>CPU_TIME</code> CPU times (in seconds) spent at each step of each part of the calculation<br><code>DISK_USAGE</code> highest total disk usage in GB<br><code>ATOMIZATION_ENERGY</code> atomization energy at charge 0 (all methods)<br><code>IONIZATION_ENERGY</code> ionization energy for all methods<br><code>ELECTRON_AFFINITY</code> electron affinity for all methods<br><code>HOMO_ENERGY</code> HOMO energy from DFHF calculations<br><code>LUMO_ENERGY</code> LUMO energy from DFHF calculations<br><code>QM9_ID</code> ID of the molecule in the QM9 dataset</p> <p><strong>QM9IPEA_atom_ens.json</strong></p> <p><code>SPINS</code> the spin assigned to elements during calculations of atomic energies<br><code>ENERGY</code> energies of atoms using different methods</p> <p> </p> <p> </p> <p>All energies are given in Hartrees with NaN indicating the calculation failed to converge.

The latter two steps appeared since we reused relevant integrals calculated for neutral species in charged species' calculations; we also used restart functionality to use HF density matrix obtained for the neutral species as the initial density matrix guess for the SCF-HF calculation for charged species.
