Magnetoelastic filaments Magnetoelasticity is the effect of elastic strain upon the magnetization of a ferromagnetic elastic material (as when the magnetization of a steel spring…

Colloidal Gold A gold colloid is a suspension consisting of sub-micron gold nanoparticles suspended within a solvent, most often water. It is a sol or…

Electrospray Ionization – a soft ionization technique Electrospray ionization (ESI) generates intact gas-phase ions from analytes in the solution for mass spectrometric investigations. It is…

Acoustic levitation uses acoustic radiation forces to counteract gravity and suspend objects in mid-air. It is a method for suspending matter in the air against…

In aerodynamic levitation, solids and liquids are floated in a vertical gas stream. Aerodynamic levitation is the use of gas pressure to levitate materials so…

Casimir Effect – in quantum field theory The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. In…

A clinostat is an apparatus for studying tropisms in plants, usually a rotating disc to which the plant is attached so that it receives an…

A tractor beam is a device with the ability to attract one object to another from a distance. In science fiction, it is a hypothetical…

Anti-gravity is the antithesis of gravity; a hypothetical force by which a body of positive mass would repel a body of negative mass. It also…

The term gravitational shielding refers to a hypothetical process of shielding an object from the influence of a gravitational field. In classical Newton’s theory of…

The Coriolis force acts in a direction perpendicular to Earth’s rotational axis. In physics, the Coriolis force is an inertial or fictitious force that acts…

Artificial gravity is a simulated gravity or sensation of weight established within a spacecraft by means of the craft’s rotation, acceleration, or deceleration. It is…
