"Pyrogenic" Natural Recordings by Native Speakers
Describing something that induces or is caused by fever.
Pyroelectricity is the property of certain crystals that show a temporary polarization and hence a temporary dipole moment when heated or cooled. This phenomenon was first detected by the German scientist Bernhard Riemann in 1887.
Pyroelectricity is a property of certain materials that cause them to generate an electric charge when they are heated or cooled. This effect is reversible, meaning that the charge is not retained after the heating or cooling is stopped. When a pyroelectric material is heated, it expands and its polarization (the alignment of its electric dipoles) changes, resulting in the creation of an electric charge. This charge can be harnessed to generate electricity.<br><br>Examples of materials that exhibit pyroelectricity include certain types of crystals, such as tourmaline, and some types of ceramics and plastics. Pyroelectricity is a type of piezoelectricity, a broader class of effects where certain materials generate an electric charge in response to mechanical stress or other changes in their environment.
Pyrogallate refers to a polyphenolic compound that has a 1,2,3-trihydroxybenzene structure (C6H3(OH)3).
Pyrogallic refers to something related to or containing gallic acid, a type of organic compound. In a broader sense, it can also imply a fiery or burning quality.
Pyrogallol is a chemical compound, a trihydroxybenzene. It is a modification of gallic acid, being obtained by the synthesis of gallic acid with sodium or potassium hydroxide. This compound is a potent disinfectant and is used to treat certain medical conditions. It can be corrosive and cause burns on the skin and in the eyes.
Pyrogen refers to a substance that induces a fever, typically in the form of a heat produced by the body in response to the introduction of an infectious agent or a foreign substance. It can also refer to a substance that causes inflammation, such as a fever-inducing toxin or a chemical reaction that generates heat.
Pyrogenation refers to the production of heat, usually in the context of biological systems, particularly in relation to the body's temperature regulation. It can also pertain to a chemical change or process that generates heat, such as a pyrogenic or heat-producing reaction.
Pyroglutamic acid (5-oxoproline), commonly known as 5-oxoproline or pyroglutamic acid, is an organic compound that serves as a five-membered heterocyclic lactam.
Pyroglutamine, also known as pyroglutamic acid or 5-oxoproline, is a naturally occurring compound produced from the breakdown of the amino acid glutamine.
Glyptic art is a method of enriched drawing in which designs are scratched or engraved on various materials, such as stone or metal. The most well-known artifacts associated with glyptic art are ancient seals, which were elevated from simple determinative signs to erotic pictorial compositions. They feature kisses, naked male and female forms embracing.
A type of hieroglyph associated with fire or heat. It typically depicted a stylized image of flames, a torch, or a burning substance, and was used to convey concepts such as warmth, energy, and spiritual power in ancient Mesopotamian and related cultures, including the Egyptians.
