🔬 Nanotechnology Fundamentals
Nanotechnology is the manipulation of matter at the atomic and molecular scale, typically between 1 and 100 nanometers.
Quantum Size Effects
The relationship between particle size and quantum properties:
E = ħ²π²/(2mL²)
Where E is the energy level, ħ is the reduced Planck constant, m is the particle mass, and L is the characteristic size.
Surface Area to Volume Ratio
The relationship between surface area and volume in nanoparticles:
SA/V = 3/r
Where SA/V is the surface area to volume ratio and r is the radius of the particle.
Van der Waals Forces
Intermolecular forces that become significant at the nanoscale:
F = -6A/(r⁷) + 12B/(r¹³)
Where A and B are constants, and r is the distance between molecules.
⚛️ Key Insight: At the nanoscale, quantum effects dominate, and materials exhibit unique properties that differ from their bulk counterparts.
