"Polymetallic" Natural Recordings by Native Speakers
Having or consisting of multiple metals.Example: The polymetallic nodules found on the ocean floor contain a combination of copper, zinc, and nickel.
Capable of undergoing polymerization, especially the process of combining to form a polymer.
Polymerization is a chemical reaction in which small molecules, such as monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. This process is a type of condensation reaction and is often initiated by heat, light, or a catalyst.
To combine or merge molecules to form a polymer, often through a chemical reaction such as polymerization, bonding the molecules together to create a more complex molecule or large chain.
Formed or composed of polymers, particularly in the process of undergoing polymerization, a chemical reaction in which various molecules combine to produce a large molecule, or polymer.
The process of polymerizing refers to the chemical reaction in which small molecules known as monomers combine to form a large molecular chain called a polymer. This process can occur naturally or be induced artificially through heat, pressure, or the presence of a catalyst. In general, polymerization involves the formation of chemical bonds between the monomer molecules to produce a larger, three-dimensional polymer chain. This process is commonly used in the production of synthetic materials, including plastics, adhesives, and fibers.
Having many such parts or occurrences.Example: The polymerous flowers are arranged in clusters.In biology, it refers to a cell division in which a single cell splits into multiple cells, resulting in a multinucleate cell.In botany, it refers to a flower or inflorescence that has multiple ovaries in a single receptacle.
Polymer: A large molecule, made from many repeated subunits, such as a long chain or network, typically having high molecular weight.Synonyms: Macromolecule, Large molecule, Synthetic fibre.Antonyms: Simple molecule, Small molecule.Example sentence: "The new plastic bags are made from a type of polymer that is biodegradable."
Poly(methyl) refers to a polymer consisting of methyl (CH3) groups. Poly(methyl) can also refer to Poly(methyl methacrylate) (PMMA), a transparent thermoplastic made of plastic polymer.In biochemistry, "Poly(methyl)" can refer to polymers of methyl groups in metabolic pathways, such as in the production of poly(methyl-glutaconate), a polyketide intermediate.In organic chemistry, a polymethyl compound is a type of molecule that contains repeating methyl groups.
Polymicrobial refers to the presence or growth of multiple microorganisms, such as bacteria, viruses, fungi, or other microbes, in a particular environment, sample, or infection. This can include mixtures of different species, strains, or types of microbes that work together or separately to produce effects, cause disease, or influence ecological or pathological processes.
Polymicrogyria is a rare brain malformation characterized by an excessive number of small folds (gyri) on the brain's surface. This condition can affect various parts of the brain, including the cerebral cortex, cerebellum, or brainstem.The term "polymicrogyria" comes from the Greek words "poly" (many) and "microgyria" (small folds). In individuals with polymicrogyria, the normal six-layered structure of the neocortex is often disrupted, leading to a decreased distance between the gyri and an abnormal cortical lamination pattern.Polymicrogyria can be classified into different subtypes based on its location and extent, which can help clinicians diagnose the condition more accurately. Some common subtypes include:1. Perisylvian cortical polypmicrogyria: affects the sylvian fissure area.2. Bilateral perisylvian polymicrogyria: affects both sides of the sylvian fissure area.3. Landau-Kleffner syndrome (LKS): affects the language areas of the brain.4. Subcortical band heterotopia: involves abnormal band-like structures in the subcortical area.Symptoms of polymicrogyria vary greatly among affected individuals, depending on the extent and location of the brain malformation. People with polymicrogyria may experience developmental delays, seizures, intellectual disability, speech and language difficulties, and muscle weakness or paralysis.
A rare or obsolete word!Polymict means "of or relating to a mixture of two or more different things; mingled; composed of diverse parts or elements."It can also be used to describe a type of sedimentary deposit, such as a polymict conglomerate, which is a rock that is composed of a mixture of different-sized clasts or fragments.In a more modern sense, the word can also be used figuratively to describe a mixture of different ideologies, cultures, or styles, such as a polymict ideology that combines elements from multiple sources.It's worth noting that this word is not commonly used in everyday language, and is generally only encountered in academic or scientific contexts.
Polymide is a type of high-performance synthetic fiber or resin made from a polyamide polymer. It is known for its excellent mechanical properties, such as high tensile strength, chemical resistance, and thermal stability.In more specific contexts, the word "polymide" can also refer to:<em> Polymide film: a type of thin, strong, and flexible film made from a polymide polymer, often used in applications such as electrical insulation, adhesives, and coatings.</em> Polymide-based resins: a type of thermoplastic resin known for its high weight-to-strength ratio, resistance to abrasion and chemicals, and ability to withstand high temperatures.Additionally, Polymide is also a brand name of a type of adhesive film made by a Chinese company.
