Molvelle AR brings you into the molecular world of Sugammadex, a modified cyclodextrin used to reverse anesthesia effects. This augmented reality app allows you to visualize how Sugammadex binds with Rocuronium—a muscle relaxant crucial in anesthetic procedures—as well as with Cholesterol and Vitamin D3. Using molecular dynamics simulations (originally conducted in water, with solvent removed for clarity), the app provides an immersive experience. Rotate the interactive volvelle to switch between ligands and observe each binding interaction in detail, making this app a valuable tool for education and research. Developed within the framework of the European Bicyclos project (EC-funded Staff Exchange project n° 101130235) in collaboration with the University of Santiago de Compostela, MD.USE Innovations SL, Carbohyde, and IES Rosalía de Castro, Santiago de Compostela. Features: Interactive volvelle to select and explore Sugammadex binding with Rocuronium, Cholesterol, or Vitamin D3. 3D molecular dynamics simulations illustrating binding orientations. Educational content on Sugammadex’s role in anesthetic reversal and its research applications. Augmented reality for an engaging educational and research experience in molecular science. Step into molecular interactions with Volvelle AR—where education and research converge in augmented reality.

Explore the true size of countries, continents, and regions with TrueSize app. Move territories around an interactive map and compare their real proportions without the size distortion of traditional flat maps. Key Features • True-size comparisons Compare countries and regions using spherical geometry, without the size distortion caused by flat map projections. • 750,000+ geographic regions Explore countries, territories, states, provinces, historical borders, islands, and more. • Historical timeline Play through history or jump to any year, BC or AD, and watch borders, names, and flags change on the map. • Population tool Draw a circle anywhere on the map and see roughly how many people live inside it, along with the population density. • Languages and language families See the approximate areas where languages and language families are spoken, then move and compare them like any other region. • Natural features Explore mountains, peaks, deserts, islands, peninsulas, archipelagos, seas, bays, lakes, rivers, and river basins. • Geography games Play the TrueSize Challenge to guess the larger territory, or test your knowledge with the Flag Quiz. • Measurement tools Measure true geodesic distances in kilometers or miles, check compass bearings, and draw custom shapes. • Edit any boundary shape Modify the vertices of countries, regions, and other map shapes directly on the map. Add, move, select, or delete points with Undo and Redo support. • Facts and geographic details View population, area, flags, and useful facts for regions you explore. • Import & edit GeoJSON / TopoJSON files Load your own map data, modify shapes, simplify or merge boundaries, and export your changes. Ideal for students, educators, and GIS enthusiasts. • Share your discoveries Create and share interactive map comparisons with others. Perfect For • Students learning geography and map accuracy • Teachers explaining map projection distortion and how borders changed through history • Travelers visualizing distances and regions • Geography enthusiasts exploring historical and modern borders • Language lovers discovering where the world's languages are spoken • Anyone curious about the real scale of our world Why TrueSize? Traditional flat maps can significantly distort the apparent size of countries and regions, especially near the poles. TrueSize uses spherical geometry to provide more realistic size comparisons while letting you freely move and explore territories around the globe. From the creators of TrueSize.net, the official TrueSize app brings interactive geography tools, hundreds of thousands of regions, a historical timeline, population and language maps, games, measurements, and custom geographic data to your device. Rediscover the world as it truly appears – clearly, accurately, and interactively.
