Piezoluminescence
Piezoluminescence is a form of luminescence created by pressure upon certain solids. This phenomenon is characterized by recombination processes involving electrons, holes and impurity ion centres. Some piezoelectric crystals give off a certain amount of piezoluminescence when under pressure. Irradiated salts, such as NaCl, KCl, KBr and polycrystalline chips of LiF (TLD-100), have been found to exhibit piezoluminescent properties. It has also been discovered that ferroelectric polymers exhibit piezoluminescence upon the application of stress. In the folk-literature surrounding psychedelic production, DMT, 5-MeO-DMT, and LSD have been reported to exhibit piezoluminescence. As specifically noted in the book '' Acid Dreams'', it is stated that Augustus Owsley Stanley III, one of the most prolific producers of LSD in the 1960s, observed piezoluminescence in the compound's purest form, an observation confirmed by Alexander Shulgin: "A totally pure salt, when dry and when shaken in th ...

Luminescence
Luminescence is a spontaneous emission of radiation from an electronically or vibrationally excited species not in thermal equilibrium with its environment. A luminescent object emits ''cold light'' in contrast to incandescence, where an object only emits light after heating. Generally, the emission of light is due to the movement of electrons between different energy levels within an atom after excitation by external factors. However, the exact mechanism of light emission in vibrationally excited species is unknown. The dials, hands, scales, and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as ''luminising''. Types * Ionoluminescence, a result of bombardment by fast ions * Radioluminescence, a result of bombardment by ionizing radiation * Electroluminescence, a result of an electric current passed through a substance ** Cathodoluminescence, a result of a luminescent material being struck by elect ...

Mechanoluminescence
Mechanoluminescence is light emission resulting from any mechanical action on a solid. It can be produced through ultrasound, or through other means. * Electrochemiluminescence is the emission induced by an electrochemical stimulus. * Fractoluminescence is caused by stress that results in the formation of fractures, that in turn yield light. * Piezoluminescence is caused by pressure that results in elastic deformation and large polarization from the piezoelectric effect. * Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound. * Triboluminescence is nominally caused by rubbing, but sometimes occurs because of resulting fractoluminescence. It is often used as a synonym. See also *List of light sources This is a list of sources of light, the visible part of the electromagnetic spectrum. Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different freque ...

Piezoelectricity
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The piezoelectric effect is a reversible process: materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied. The inverse piezoelectric effect is used in the pro ...

Dimethyltryptamine
Dimethyltryptamine (DMT), also known as ''N'',''N''-dimethyltryptamine (''N'',''N''-DMT), is a Psychedelic drug, serotonergic hallucinogen and Investigational New Drug, investigational drug of the substituted tryptamine, tryptamine family that natural product, occurs naturally in many plants and animals, including humans. DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. DMT has a rapid onset of action, onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the "businessman's trip" during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as Lysergic acid diethylamide, LSD or psilocybin mushrooms. DMT can be inhaled or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last about five to fifteen minutes ...

5-MeO-DMT
5-MeO-DMT (5-methoxy-''N'',''N''-dimethyltryptamine), also known as ''O''-methylbufotenin or mebufotenin (), is a naturally occurring psychedelic of the tryptamine family. It is found in a wide variety of plant species, and is also secreted by the glands of at least one toad species, the Colorado River toad. It may occur naturally in humans as well. Like its close relatives dimethyltryptamine (DMT) and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include ''five-methoxy'', ''the power'', ''bufo'', and ''toad venom''. The drug has been described as the most powerful psychedelic and, by journalist Michael Pollan, as the "Mount Everest of psychedelics". Adverse effects of 5-MeO-DMT include sickness, vomiting, headache, chest pressure, fatigue, anxiety, fear, terror, confusion, paranoia, crying, loss of awareness and motor control, and reactivations. The drug acts as a non-selective serotonin receptor agonist, including of the sero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lysergic Acid Diethylamide
Lysergic acid diethylamide, commonly known as LSD (from German ; often referred to as acid or lucy), is a Semisynthesis, semisynthetic, Hallucinogen, hallucinogenic compound derived from ergot, known for its powerful psychological effects and Serotonin, serotonergic activity. It was historically significant in psychiatry and 1960s counterculture; it is currently legally restricted but experiencing renewed scientific interest and increasing use. When taken orally, LSD has an onset of action within 0.4 to 1.0 hours (range: 0.1–1.8 hours) and a duration of effect lasting 7 to 12 hours (range: 4–22 hours). It is commonly administered via tabs of Blotting paper, blotter paper. LSD is extremely potent, with noticeable effects at doses as low as 20 Microgram, micrograms and is sometimes taken in much smaller amounts for microdosing. Yet no fatal human overdoses have been documented. LSD is mainly used recreationally or for spiritual purposes. LSD can cause mystical experiences. ...

Acid Dreams (book)
''Acid Dreams: The Complete Social History of LSD: the CIA, the Sixties, and Beyond'', originally released as ''Acid Dreams: The CIA, LSD, and the Sixties Rebellion'', is a 1985 book by Martin A. Lee and Bruce Shlain, in which the authors document the 40-year social history of lysergic acid diethylamide (LSD), beginning with its synthesis by Albert Hofmann of Sandoz Pharmaceuticals in 1938. During the Cold War period of the early 1950s, LSD was tested as an experimental truth drug for interrogation by the United States intelligence and military community. Psychiatrists also used it to treat depression and schizophrenia. Under the direction of Sidney Gottlieb, the drug was used by the Central Intelligence Agency (CIA) in cooperation with participating "colleges, universities, research foundations, hospitals, clinics, and penal institutions". LSD was tested on "prisoners, mental patients, volunteers, and unsuspecting human subjects". In the mid to late 1950s, many intellect ...

Owsley Stanley
Augustus Owsley Stanley III (January 19, 1935 – March 12, 2011) was an American-Australian audio engineer and clandestine chemist. He was a key figure in the San Francisco Bay Area hippie movement during the 1960s and played a pivotal role in the decade's counterculture. Under the professional name Bear, he was the sound engineer for the Grateful Dead, recording many of the band's live performances. Stanley also developed the Grateful Dead's Wall of Sound, one of the largest mobile sound reinforcement systems ever constructed. Stanley also helped Robert Thomas design the band's trademark skull logo. Called the Acid King by the media, Stanley was the first known private individual to manufacture mass quantities of LSD. By his own account, between 1965 and 1967, Stanley produced at least 500 grams of LSD, amounting to a little more than five million doses. He died in a car accident in Australia (where he had taken citizenship in 1996) on March 12, 2011. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Shulgin
Alexander Theodore "Sasha" Shulgin (June 17, 1925 – June 2, 2014) was an American biochemist, broad researcher of synthetic psychoactive compounds, and author of works regarding these, who independently explored the organic chemistry and pharmacology of such agents—in his mid-life and later, many through preparation in his home laboratory, and testing on himself. He is acknowledged to have introduced to broader use, in the late 1970s, the previously-synthesized compound MDMA ("ecstasy"), in research psychopharmacology and in combination with conventional therapy, the latter through presentations and academic publications, including to psychologists; and for the rediscovery, occasional discovery, and regular synthesis and personal use and distribution, of possibly hundreds of Psychoactive drug, psychoactive compounds (for their Psychedelic drug, psychedelic and MDMA-like empathogenic bioactivity, bioactivities). As such, Shulgin is seen both as a pioneering and a controversi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ann Shulgin
Laura Ann Shulgin ( Gotlieb; March 22, 1931 – July 9, 2022) was an American author and the wife of chemist Alexander Shulgin, with whom she wrote ''PiHKAL'' and '' TiHKAL''. Life and career Laura Ann Gotlieb Detailed biography of Ann Shulgin was born in Wellington, New Zealand, to parents Bernard Gotlieb and Gwen Ormiston, but grew up in the village Opicina outside the Italian city Trieste.

Triboluminescence
Triboluminescence is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed (see tribology). The phenomenon is not fully understood but appears in most cases to be caused by the separation and reunification of static electric charges, see also triboelectric effect. The term comes from the Greek τρίβειν ("to rub"; see tribology) and the Latin ''lumen'' (light). Triboluminescence can be observed when breaking sugar crystals and peeling adhesive tapes. ''Triboluminescence'' is often a synonym for ''fractoluminescence'' (a term mainly used when referring only to light emitted from fractured crystals). Triboluminescence differs from piezoluminescence in that a piezoluminescent material emits light when deformed, as opposed to broken. These are examples of mechanoluminescence, which is luminescence resulting from any mechanical action on a solid. History Quartz rattlers of the Uncompahgre Ute indigenous ...
