An explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances.
Wilson's disease is a genetic disorder in which excess copper builds up in the body. Symptoms are typically related to the brain and liver. Liver-related symptoms include vomiting, weakness, fluid build up in the abdomen, swelling of the legs, yellowish skin and itchiness. Brain-related symptoms include tremors, muscle stiffness, trouble speaking, personality changes, anxiety, and psychosis.
Hexamethylenetetramine or methenamine, also known as hexamine or urotropin, is a heterocyclic organic compound with the formula (CH2)6N4. This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane. It is useful in the synthesis of other organic compounds, including plastics, pharmaceuticals, and rubber additives. It sublimes in vacuum at 280 °C.
Ammonal is an explosive made up of ammonium nitrate and aluminium powder, not to be confused with T-ammonal which contains trinitrotoluene as well to increase properties such as brisance.
Rodenticides are used to kill not only rats and mice, but also squirrels, woodchucks, chipmunks, porcupines, nutria, beavers, and voles. They are typically non-specific pest control chemicals made and sold for the purpose of killing rodents.
Adamantane is an organic compound with a formula C10H16 or, more descriptively, (CH)4(CH2)6. Adamantane molecules can be described as the fusion of three cyclohexane rings. The molecule is both rigid and virtually stress-free. Adamantane is the most stable isomer of C10H16. The spatial arrangement of carbon atoms in the adamantane molecule is the same as in the diamond crystal. This similarity led to the name adamantane, which is derived from the Greek adamantinos (relating to steel or diamond). It is a white solid with a camphor-like odor. It is the simplest diamondoid.
Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor 'sweat', are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct. There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species:
Michael Heidelberger was an American immunologist. He and Oswald Avery showed that the polysaccharides of pneumococcus are antigens, enabling him to show that antibodies are proteins. He spent most his early career at Columbia University and comparable time in his later years on the faculty of New York University. In 1934 and 1936 he received the Guggenheim Fellowship. In 1967 he received the National Medal of Science, and then he earned the Lasker Award for basic medical research in 1953 and again in 1978. His papers are held at the National Library of Medicine in Bethesda, Maryland.
Penicillamine, sold under the trade names of Cuprimine among others, is a medication primarily used for the treatment of Wilson's disease. It is also used for people with kidney stones who have high urine cystine levels, rheumatoid arthritis, and various heavy metal poisonings. It is taken by mouth.
Palladium(II) dicyanide is the inorganic compound with the formula Pd(CN)2. A yellow solid, it is a coordination polymer. It was the first palladium compound isolated in pure form. In his attempts to produce pure platinum metal in 1804, W.H. Wollaston added mercuric cyanide to a solution of impure platinum metal in aqua regia. This precipitated palladium cyanide which was then ignited to recover palladium metal—a new element.
Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with the molecular formula N(CH3)4+ OH−. It is commonly encountered as concentrated solutions in water or methanol. The solid and solutions are colorless, or yellowish if impure. Although TMAH has virtually no odor when pure, samples often have a strongly fishy smell from the trimethylamine which is a common impurity. TMAH has numerous and diverse industrial and research applications.
Tetramethylenedisulfotetramine (TETS) is an organic compound that is used as a rodenticide. It is an odorless, tasteless white powder that is slightly soluble in water, DMSO and acetone, and insoluble in methanol and ethanol. TETS is a sulfamide derivative. It can be synthesized by reacting sulfamide with formaldehyde under acidic condition. When crystallized from acetone, it forms cubic crystals with a melting point of 255–260 °C.
PLX, or Picatinny Liquid Explosive, is a liquid binary explosive, a mixture of 95% nitromethane (NM) along with 5% ethylene diamine (EDA) as a sensitizer. Other amine compounds can be used instead of ethylene diamine, such as triethylene tetramine or ethanolamine, but EDA has been found to be most effective. PLX is a fairly powerful high explosive, marginally exceeding the destructive yield of TNT.
Buccinum undatum, the common whelk or the waved buccinum, is a large, edible marine gastropod in the family Buccinidae, the "true whelks".
The Sommelet reaction is an organic reaction in which a benzyl halide is converted to an aldehyde by action of hexamine and water.
Neptunea antiqua, common name the red whelk, is a species of Northeast Atlantic sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks.
Barbitonia arthritica is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks.
Buccinum leucostoma, common name the yellow-mouth buccinum, is a species of sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks.
Tetramethylammonium (TMA) or (Me4N+) is the simplest quaternary ammonium cation, consisting of four methyl groups attached to a central nitrogen atom, and is isoelectronic with neopentane. It is positively charged and can only be isolated in association with a counter-ion. Common salts include tetramethylammonium chloride and tetramethylammonium hydroxide. Tetramethylammonium salts are used in chemical synthesis and are widely employed in pharmacological research.
In chemistry, a macrocyclic ligand is a macrocycle with a ring size of at least nine and three or more donor sites. Classic examples are crown ethers and porphyrins. Macrocyclic ligands exhibit particularly high affinity for metal ions.
