CP2K is a software tool for performing atomistic and molecular simulations. It is used to study the  (more)properties of materials, such as their electronic structure, structural stability, and chemical reactivity. CP2K is based on density functional theory (DFT), a computational method for predicting the behavior of electrons in materials based on quantum mechanics. It includes a range of features for performing atomistic simulations, such as calculating energy levels, optimizing structures, and predicting the properties of materials. CP2K is developed by a team of researchers at ETH Zurich in Switzerland and is available for free download for Windows, Linux, and Unix operating systems. It is widely used in research and industry to study the properties of materials and chemical systems. Operating system: Linux, Windows License: GNU General Public License

RQDA (R-based Qualitative Data Analysis) is a software tool for analyzing qualitative data, such as  (more)text, audio, and video. It is an open-source software program developed by the R Project and is used in a variety of applications, including social science research, education, and healthcare. RQDA includes a range of features for organizing, coding, and analyzing qualitative data, such as tools for transcribing audio and video, creating and managing codebooks, and generating reports. It is used to study the content and meaning of qualitative data, such as conversations, interviews, and observations. RQDA is available for free download for Windows, macOS, and Linux operating systems. It is often used in conjunction with other software tools, such as the statistical programming language R.
