Ricerca di articoli scientifici semantici
Semantic Scholar is a free search engine for scientific literature, run by the Allen Institute for AI (Ai2). It indexes over 238 million papers from all fields and adds citation information and AI assisted reading features such as the Semantic Reader. The originality of Semantic Scholar lies in its public API, giving programmatic access to […]
Archivio di preprint arXiv
arXiv is the open access archive of about 2.4 million preprints in physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. Authors post the papers, and arXiv does not peer review them. Subject browsing, daily new and recent listings per category, and an advanced search allow close tracking […]
JupyterLite Python Notebooks nel browser
JupyterLite is a distribution of JupyterLab that runs entirely in the web browser. Python code executes through WebAssembly, so no server and no local Python installation are needed. Notebooks, files and settings are stored in the browser. It starts in seconds and offers the familiar notebook interface with interactive widgets. The limits are real: it […]
NIST Chemistry Webbook
The NIST Chemistry WebBook is the online reference of NIST Standard Reference Database 69. It provides thermochemical, thermophysical and ion energetics data for over 40,000 chemical species, together with IR, mass and UV/Vis spectra, gas chromatography retention indexes and computed 3D structures.Search works by name, formula, CAS number, InChI, reaction, author or molecular weight.The data […]
CoBLIS, simulatore di daltonismo.
CoBLIS (for Color BLIndness Simulator.) transforms an uploaded image to show how it appears to people with red, green, blue or complete color blindness. A pan and zoom function allows inspection of details. All calculations should run on your own machine, so no image is uploaded and there is no size limit. Note: the simulation […]
MolView Visualizzatore ed editor di molecole (2D e 3D)
MolView combines a structural formula editor with a 3D model viewer in the browser. You draw a molecule, convert it to 3D, then rotate or measure it.Super great: it can also searches PubChem compounds, RCSB Protein Data Bank macromolecules and the Crystallography Open Database.It shows mass, IR and predicted H1 NMR spectra, exports MOL, PDB […]
