## Visão geral

Interactive visualization of carbon nanomaterials - Explore graphene (2D honeycomb sp² lattice, single-atom layer), carbon nanotubes with chirality (n,m) classification showing armchair (n=n) metallic, zigzag (n,0) semiconducting, and chiral (n≠m≠0) types, fullerene C₆₀ truncated icosahedron structure, and carbon nanofibers. Features interactive 3D Three.js visualization with real-time parameter adjustment for nanotube chirality (n=1-10, m=0-10), diameter calculation d = (a/π)√(n²+m²+nm) where a=0.246nm, automatic metallic/semiconducting classification based on (n-m)%3==0 condition, rotation animation control, and display options (atoms, bonds, labels, electron flow animation). Electronic structure visualization showing Dirac cones at K and K' points with linear dispersion E(k)=±ħvF|k|, zero band gap semiconductor behavior, carrier mobility ~200,000 cm²/V·s, and density of states vanishing at Dirac point. Physical properties display including electrical conductivity ~10⁶ S/m (high mobility from sp² hybridization and delocalized π-electrons), thermal conductivity ~5000 W/m·K (exceptional from strong covalent bonds and phonon transport), mechanical strength with Young's modulus ~1 TPa (130 GPa tensile strength, strongest material ever measured), and surface area ~2630 m²/g (theoretical specific surface area). Chirality diagram showing hexagonal lattice with basis vectors a₁ and a₂, chiral vector Cₕ=n·a₁+m·a₂, and real-time visualization of chirality vector changes. Band gap calculation: graphene 0 eV (zero-gap), CNTs metallic if (n-m)%3==0 else semiconducting with Eg≈0.9/(n+m) eV, fullerene ~1.9 eV, nanofiber ~0.5 eV variable. Applications covered include electronics (transistors, interconnects, flexible displays, touch screens), composites (reinforced polymers, conductive materials, structural components), energy storage (batteries, supercapacitors, fuel cells, hydrogen storage), and sensors (gas sensors, biosensors, strain sensors, chemical detection). Synthesis methods explained: Chemical Vapor Deposition (CVD) for large-area growth using hydrocarbon gases on metal catalysts, Arc Discharge high-temperature method producing high-quality CNTs and fullerenes using graphite electrodes, Laser Ablation for high-purity CNT synthesis using laser vaporization of graphite target, and Exfoliation (mechanical/chemical) for producing graphene layers. Comprehensive educational content covering carbon allotropes based on sp² hybridization, graphene structure and properties (2D honeycomb lattice, Dirac cone electronic structure, exceptional mechanical and thermal properties), CNT chirality and electronic properties (armchair/zigzag/chiral classification, diameter-dependent properties, metallic vs semiconducting behavior), fullerene C₆₀ structure (truncated icosahedron with 12 pentagons + 20 hexagons, 1.9 eV band gap, electron acceptor properties), and carbon nanofiber multi-walled structures. Perfect for chemistry education, materials science learning, nanotechnology understanding, and exploring carbon allotropes, nanomaterial properties, electronic structure, and applications in electronics, energy storage, and composite materials.
