Magnetic resonance, absorption or emission of electromagnetic radiation by electrons or atomic nuclei in response to the application of certain magnetic fields. The principles of magnetic resonance are applied in the labor ...
Experiments on salts of the iron group of elements. ESR has made possible the study of such phenomena as the structural defects that give certain crystals their colour, the formation and destruction of free rad ...
In chemistry, orbital hybridisation is the concept of mixing atomic orbitals into new hybrid orbitals suitable for the pairing of electrons to form chemical bonds in valence bond theory. ...
In physics and engineering, fluid dynamics is a sub-discipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several sub-disciplines, including aerodynamics (the study of air and other gases in motion) and hy ...
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and properties of matter. The behavior of these quantities is governed by the four laws of thermodynamics which convey a qu ...
Dye, substance used to impart colour to textiles, paper, leather, and other materials such that the colouring is not readily altered by washing, heat, light, or other factors to which the ma ...
Biomass production refers to the increase in the amount of organic matter. It is the addition of organic matter in a given area or population. Biomass is considered renewable energy because it is replenished as plants an ...
Natural products are small molecules produced naturally by any organism including primary and secondary metabolites. They include very small molecules, such as urea, and complex structures, such as Taxol. As they may onl ...
A natural product is a chemical compound or substance produced by a living organism that is, found in nature.In the broadest sense, natural products include any substance produced by life. Natural products can also be pr ...

Phytochemicals are chemicals of plant origin. Phytochemicals are chemicals produced by plants through primary or secondary metabolism. They generally have biological activity in the plant host and play a role in ...
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt curren ...
The plants and animals that live and then die are the bio part; the earth that they decompose into comprises the geo part; and the process by which organic matter returns to the chemical elements in the earth is explained by the chemical part. The ...

A chemical hazard is a type of occupational hazard caused by exposure to chemicals in the workplace. Exposure to chemicals in the workplace can cause acute or long-term detrimental health effects. The use of chemicals has increased ...
In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime.The moving fluid creates a space devoid of downstream-flowing fluid on the downst ...
The Batchelor vortex is an approximate solution to the Navier-Stokes equations obtained using a boundary layer approximation. The physical reasoning behind this approximation is the assumption that the axial gradient of the flo ...
