MatSearch Live

MatSearch brings the world's two largest open materials databases — Materials Project and NOMAD — to your pocket. Type a chemical formula or take a photo, and explore the computed properties of thousands of materials in seconds. TWO DATABASES, ONE APP • Materials Project: inorganic crystals, stability, electronic & mechanical properties • NOMAD: millions of DFT calculations; compare different methods (GGA, hybrid...) for the same material • Choose which database to search in WAYS TO SEARCH • Search by chemical formula (e.g. Fe2O3, TiO2, GaN) — case-insensitive • Natural-language search (e.g. "table salt") — AI converts it to a formula • Photo identification: snap an object, let the AI identify its material • Ion group search (phosphate, sulfate, carbonate...) + element filter • Search NOMAD by uploader (researcher) EXPLORE • Interactive periodic table: 118 elements with phase, melting/boiling point, density, electronegativity, electron configuration • Compound Finder: pick 2-3 elements, see every known compound in that system • Material comparison: put 3 materials side by side, highlight differences, share FEATURES • 3D crystal structure viewer (including molecules) • Electronic: band gap (DFT-PBE), direct/indirect type, metal/semiconductor/insulator class • Density of States (DOS) and band structure plots • Optical & dielectric: refractive index, dielectric constant, piezoelectric modulus • Mechanical: bulk modulus, shear modulus, Poisson ratio, elastic anisotropy • Magnetic and thermodynamic properties; phase diagram (stability curve) • Molecular calculations (NOMAD): HOMO-LUMO, total energy, functional and basis set • Molecular data for organics/plastics (PubChem) • Favorites, search history, light/dark theme • English, Turkish, German WHO IS IT FOR? A quick reference tool for students, researchers and enthusiasts in materials science, chemistry, physics and engineering. DATA SOURCES Data comes from the Materials Project (materialsproject.org) and NOMAD (nomad-lab.eu) under CC-BY 4.0, and from PubChem for organic molecules. MatSearch is an independent viewer app and is not an official product of these projects. IMPORTANT NOTE Band gaps are computed with the DFT-PBE method and may underestimate experimental values. Data is for scientific reference and educational purposes.
