Since its discovery a few years ago, the Boyajian’s star has become an interesting mystery. The star experiences fading events that astronomers still cannot explain.…

Escape velocity is the speed that an object needs to be traveling to break free of a planet or moon’s gravity well and leave it…

Also known as the microwave hearing effect or the Frey effect, the microwave auditory effect consists of audible clicks caused by pulsed/modulated microwave frequencies that…

The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also called micron, metric…

In simple terms, mirror means a smooth and highly polished glass surface, through which images are formed by reflection, as the light falls on it.…

Iron Oxide Nanoparticles Iron oxides are common natural compounds and can also easily be synthesized in the laboratory. Iron oxide nanoparticles are iron oxide particles…

Superparamagnetism is a property occurring principally in small, single-domain magnetic particles without magnetic memory. It is a form of magnetism that appears in small ferromagnetic…

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…
