Read full descriptionHide full description
ChemARise contains a library of chemical structures that can be visualized in 3D and interacted with to apply rotation, translation and scaling. The app also proposes an augmented reality mode (AR) to detect some chemical structures from university courses or scientific publications via the camera and display them in 3D. This app is designed to help students and researchers visualize the spatial arrangement of atoms in molecules to better understand concepts such as chirality, steric hindrance, or symmetry.
