Nanotechnology Part 1: Nanomechanics and Algodoo Simulator

Explore nanotechnology and nanomechanics with the Algodoo 2D simulator. Model interactive multi-physics systems under Newton’s laws and visualize forces, gravity, and friction.

Nanomaterials span 1–100 nanometers in at least one external dimension, including nanoparticles, carbon nanotubes, and nanostructured membranes, highlighting unique properties and potential on-chip applications.

Explore why small particulates rise in air due to surface charge and wind. See buoyancy, drag proportional to velocity squared, and gravity shaping motion depending on particle size and shape.

Algodoo illustrates small-particle sedimentation in liquid, where viscous drag balances gravity and buoyancy, yielding about 220 μm/s and ~7.8 minutes to travel 0.5 m.

Explore how liquid flow through nano and micro channels is shaped by inertial and viscous forces, with viscosity dominating as channel diameter shrinks, creating high external pressure needs.

Explore nanomechanics with the Algodoo simulator, modeling Brownian motion and mechanical mixers. Analyze particle dynamics at the nanoscale through hands-on simulations.

Explore nanomachines built with bottom-up self-assembly versus top-down fabrication, and analyze how diffusion, viscosity, and drag shape strength-to-weight, inertia, and gliding distance at micro scales.

Explore how drag, viscosity, and object radius set the nanocar's acceleration and coasting distance, while torque scales with the dimension to the fifth power, giving 1.4% of original torque.

Derive potential and kinetic energy for a mass and spring system, apply total energy conservation, and relate displacement and velocity to the probability distribution of position.

Explores simple harmonic motion through a mass-spring model representative of nanoscale beams and atoms, explaining elastic beams, resonance frequency, and the relationship between stiffness, mass, and period.

Explore how damping forces, including viscous damping and surface-related losses, drain energy from nanomechanical systems, lowering amplitude over time while leaving oscillation frequency unchanged.

Explore forced oscillations in nanomechanics, driven by external forces, damping, and spring forces; derive the motion equation and amplitude, and examine resonance at the damped natural frequency.

Explore nanomechanical mass sensors that detect added mass via shifts in the natural frequency of nanoscale beams, highlighting sensitivity, minimum detectable mass, and design trade-offs.

Explain the quality factor and damping effects on resonant response, showing how Q reflects peak sharpness, energy dissipation, and the relation to bandwidth in cantilever beams.

Explore mechano-chemistry by using bending cantilevers to detect molecules, linking surface stress to adsorption via Stoney and Shuttleworth relations and self-assembled monolayer coatings on gold.

Explore how the Schrödinger equation yields energy levels and wave functions. Examine the correspondence principle with the quantum harmonic oscillator and probability densities.

Explore atoms through temperature-driven vibrations, the simple harmonic oscillator framework, and Leonard–Jones potential; derive the bond spring constant from the slope at equilibrium, with an argon example.

Explore how central forces reduce a two-body system to a single mass via reduced mass, derive kinetic and potential energies, and compute bond frequencies, including Argon, in nanomechanics.

Explore quantum mechanics of oscillating atoms, using Leonardo's potential and parabolic approximations near equilibrium to derive the quantum harmonic oscillator spectrum and zero-point energy.
