title: Molecular Dynamics Simulation Data on Melting and Solidification Hysteresis in AlCoCuFeNi Nanoparticles

description: This dataset provides molecular dynamics simulation data analyzing the phase transitions (melting and solidification) of an AlCoCuFeNi high-entropy alloy nanoparticle (approx. 10 nm diameter). The data highlights the hysteresis effect between melting and crystallization temperatures.

CSV File Column Description:The data was obtained using LAMMPS "metal" units. Unless otherwise specified, energy values are extensive (total for the whole system).





Step: Simulation timestep count (Time = Step * dt).




Temp: Average system temperature (Kelvin).




alT, coT, cuT, feT, niT: Partial temperatures of specific atom groups (Aluminum, Cobalt, Copper, Iron, Nickel respectively) in Kelvin.




Press: System Pressure (Bars).




Volume: Simulation box volume (Angstroms^3).




TotEng: Total System Energy (Kinetic + Potential) in eV.




PotEng: Potential Energy of the system in eV.




Enthalpy: System Enthalpy (TotEng + Press*Volume) in eV.



Note on Data Analysis:To obtain energy per atom values, divide the total energy values (TotEng, PotEng, Enthalpy) by the total number of atoms in the system (N = 50,000). The hysteresis loop can be visualized by plotting Temperature vs PotEng/N for both heating and cooling files.

Methodology:





Software: LAMMPS




Interatomic Potential: Embedded Atom Method (EAM), parameters from Zhou et al., Phys. Rev. B 69, 144113 (2004).




Boundary conditions: Free surface (shrink-wrapped).

title: XRD pattern of Mo2Ga2C, Mo2CTx/Mo2GaC and Ni-Mo2CTx/Mo2Ga2C materials

description: In the dataset are included raw data for the preparation of XRD pattern of Mo2Ga2C, Mo2CTx/Mo2GaC and Ni-Mo2CTx/Mo2Ga2C materials.
The MAX materials were synthesised according to the procedure:
1) Gring of Mo2C powder with liquid gallium for 60 min in agate mortar at molar ration equal to Mo2C:Ga=1:10.
2)Transfer to the quartz ampule.
3) Evacuating and purging the ampule in order to remove oxygen. Closing the ampule under vacuum.
4) High-temperature annealing at 850 deg. C for 48 hours. The heating rate was maintained at 10 deg. C per minute.
5) Removing potentially formed oxides through leaching with 35% hydrochloric acid.
6) Drying under vacuum at 50 deg. C  to dry mass.
 The preparation procedure for Mo2CTx/Mo2GaC:
1) Etching of Mo2Ga2C with XF/HCl mixture (where X= Na, Li, K) under hydrothermal conditions at 90 deg. C for 24 or 48 hours.
2) Washing with water.
3) Dring at 50 deg. C under vacuum.
The preparation procedure for Ni-Mo2CTx/Mo2GaC:
1) Impregnation of previously prepared Mo2CTx/Mo2GaC with aqueous nickel nitrate solution. 
2) Dring at 50 deg. C under vacuum.

title: Extracted Data from: Chemical Safety and Hazardous Investigations Board (CSB), Current Investigations

description: “The CSB is an independent federal agency charged with investigating chemical incidents to determine the cause or probable cause. Headquartered in Washington, DC, the Agency's board members are appointed by the President and confirmed by the Senate. The CSB's public safety mission is to 'drive chemical safety excellence through independent investigations to protect communities, workers, and the environment.'
The CSB's vision is "a nation free from chemical disasters.” [Quote from https://www.csb.gov/about-the-csb/mission/, accessed on 2025-11-18.]
&lt;br /&gt; 
&lt;br /&gt; 
The Current Investigations section of the CSB website shows linked pages for incidents where the investigation is not “complete”; that is, an incident where a Final Report has not been issued yet, or the case has not been closed by the Board.
&lt;br /&gt; 
&lt;br /&gt; 
Upon download, there were eight (8) open investigations. For each investigation, a PDF of the CSB landing page (with URL links) is included in the archive. There is no README for the archive. The files are arranged as zip files with the date (YYYYMMDD) at the beginning of the zip folder name.
&lt;br /&gt; 
&lt;br /&gt; 
There are also a couple of files that pertain to several investigations that are included.
description: Another archive on CAFE Dataverse contains all of the Past Investigations data, plus Recommendations.
