In Dubuffet's ecstatic inventory of the morphology of blotted ink there's no mention of extraterrestrials, but he attests to a mystical experience of materials as the vehicle of sentient beings, insisting that "the being — more or less whimsical or spectral — populates materials we believe to be inert, in immense numbers; that supposedly deserted places are as rich in events as the heart of a great city […]" He seems to say that not only are we iconophiles, yearning to discern imagery in the arbitrary ebb and flow of pigment, we are lovers also of stories.

The crystallization vessels used are autoclaves. These are usually thick-walled steel cylinders with a hermetic seal which must withstand high temperatures and pressures for prolonged periods of time. Furthermore, the autoclave material must be inert with respect to the solvent. The closure is the most important element of the autoclave.

The support may be inert or participate in the catalytic reactions. Typical supports include various kinds of carbon, alumina, and silica. Immobilizing the catalytic center on top of nanoparticles with a large surface to volume ratio addresses this problem. In the case of magnetic nanoparticles it adds the property of facile a separation.

From the standpoint of aircraft design, air can be assumed to be inert for temperatures less than 550 K at one atmosphere pressure. The perfect gas theory begins to break down at 550 K and is not usable at temperatures greater than 2,000 K. For temperatures greater than 2,000 K, a heat shield designer must use a real gas model.

Once a pressure transmitting medium has lost its hydrostaticity, a pressure gradient forms in the chamber that increases with increasing pressure. This gradient can greatly affect the sample, compromising results. The medium must also be inert, as to not interact with the sample, and stable under high pressures. For experiments with laser heating, the medium should have low thermal conductivity.

Some resin-based materials also include an HSC with bismuth oxide. Problems have allegedly arisen with bismuth oxide because it is claimed not to be inert at high pH, specifically that it slows the setting of the HSC, but also over time can lose color by exposure to light or reaction with other materials that may have been used in the tooth treatment, such as sodium hypochlorite.

Hence, they have been renamed to 'noble gases', as the only two of these we know truly to be inert are helium and neon. However, a large amount of energy is required to drive such reactions, usually in the form of heat, pressure, or radiation, often assisted by catalysts. The resulting compounds often need to be kept in moisture-free conditions at low temperatures to prevent rapid decomposition back into their elements.

In 1898, Ernest Rutherford noted that thorium gave off a radioactive gas. In examining the radiation, he classified Becquerel radiation into two types, which he called α (alpha) and β (beta) radiation. Subsequently, Paul Villard discovered a third type of Becquerel radiation which, following Rutherford's scheme, were called "gamma rays", and Curie noted that radium also produced a radioactive gas. Identifying the gas chemically proved frustrating; Rutherford and Frederick Soddy found it to be inert, much like argon.

Mexicana maintenance personnel were blamed for negligence in maintaining the 727 and for filling the tire with compressed air, instead of nitrogen. About a year after the crash, the U.S. FAA released an Airworthiness Directive requiring the use of dry nitrogen (or other gases shown to be inert) when filling the tires on braked wheels of most commercial airliners. The crash remains the deadliest airline disaster in Mexican historyFields, Dana (May 23, 1986). Explosion, fire preceded plane crash that killed 167.

Accessed 19 May 2020.}}, showing a bioactive effect for a sphingolipid for the first time and suggesting that "a role for sphingolipids in transmembrane signaling may emerge" . Prior to this discovery, sphingolipids had primarily been thought to be inert, structural components of cell membranes. Subsequent work by Hannun and his laboratory demonstrated the turnover of sphingolipids in response to cell stimuli , analogous to phosphoinositide turnover, and the linking of sphingolipids, most notably ceramide, to biologies such as cell death, growth arrest, and differentiation.

The device was determined to be a three-foot (.9-m) long TOW missile used in the training of federal agents and bomb-sniffing dogs; although actually inert, it had been marked "live" in order to mislead arms traffickers in a planned law enforcement sting. On examination the missile was determined to be inert, and relief efforts resumed 45 minutes later. The last survivor, a 15-year-old girl found under the base of the collapsed building, was rescued at around 7 pm.

Thus, they cannot be used as oxygen carriers and are generally considered to be inert. These materials include Cr2O3 and SiO2. They can, however, be used as support materials along with active oxygen carrier materials. In addition to the relative redox potentials of metal oxide materials illustrated in Fig 1b, the development of desired oxygen carriers for chemical looping applications requires to consider such properties as oxygen carrying capacity, redox reactivity, reaction kinetics, recyclability, attrition resistance, heat carrying capacity, melting point, and production cost.

Syenite, a rising orogene star in the Fulcrum, is forcibly partnered with Alabaster, the most powerful living orogene, in order to conceive a child with him on a business trip to the countryside. Though they loathe each other, they have no choice in the matter. As they travel to their destination, Alabaster frequently alludes to hidden knowledge about the obelisks, strange crystals the size of buildings that drift amongst the clouds. They are assumed by most to be inert leftovers from a long-dead civilization.

Drugs may be sold to end users who are unaware they have been laced or are unaware what was used to lace them. At various points in the supply chain, in order to maximize profitability, many drugs are adulterated with cutting agents. Substances with similar physical and/or chemical properties can be used so the end product most closely resembles what it is purported to be. Inert substances with similar physical properties can be used to increase weight without changing the look and feel.

At that time the invoices accompanying a number of packages reflected that they contained firearm parts and accessories as well as various chemicals. He stated that in May 1992, a package which was addressed to the "Mag-Bag" accidentally broke open while it was being loaded on his delivery truck. He saw that it contained three other boxes, the contents of which were "pineapple" type hand grenades which he believed to be inert. He stated that there were about 50 of the grenades and that he later delivered them to the Mt. Carmel Center.

With no other ally, because Raven killed Chavez, Lin Feng angrily leaves the council. It is shown later that Lin Feng is actually part of The Disciples, as he is talking to Pietor Furan about what had happened. Furan orders Lin Feng to apologize to Nero and regain his seat in G.L.O.V.E. Furan then tells Dr. Creed, whom he saved from the rainforest, to conduct an autopsy on Trent, who has been dead for 2 weeks. It is believed that the Animus would be inert, but it surprisingly lurches out and consumes Dr. Creed.

Uranium trioxide reacts at 400 °C with freon-12 to form chlorine, phosgene, carbon dioxide and uranium tetrafluoride. The freon-12 can be replaced with freon-11 which forms carbon tetrachloride instead of carbon dioxide. This is a case of a hard perhalogenated freon which is normally considered to be inert being converted chemically at a moderate temperature. :2 CF2Cl2 \+ UO3 → UF4 \+ CO2 \+ COCl2 \+ Cl2 :4 CFCl3 \+ UO3 → UF4 \+ 3 COCl2 \+ CCl4 \+ Cl2 Uranium trioxide can be dissolved in a mixture of tributyl phosphate and thenoyltrifluoroacetone in supercritical carbon dioxide, ultrasound was employed during the dissolution.

Hydrogenation of the arene ring in the indenyl ligand resulted in CO substitution at about half the rate of the cyclopentadienyl compound. Work in the early 1980s by Basolo found the SN2 replacement of CO in Rh(η5-C9H7)(CO)2 to be 108 times faster than in Rh(η5-C5H5)(CO)2. Shortly afterwards, Basolo tested the effect of the indene ligand on Mn(η5-C9H7)(CO)3, the cyclopentadienyl analogue of which having been shown to be inert to CO substitution. Mn(η5-C9H7)(CO)3 did undergo CO loss and was found to substitute via an SN2 mechanism.

Slow strain rate testing (SSRT), also called constant extension rate tensile testing (CERT), is a popular test used by research scientists to study stress corrosion cracking. It involves a slow (compared to conventional tensile tests) dynamic strain applied at a constant extension rate in the environment of interest. These test results are compared to those for similar tests in a, known to be inert, environment. A 50-year history of the SSRT has recently been published by its creator.M. Henthorne, "The Slow Strain Rate Stress Corrosion Cracking Test - A 50 Year Retrospective", Corrosion, Vol 72, December 2016, NACE International.

Simons's fluorocarbons turned out to be inert enough to withstand the corrosive effects of uranium hexafluoride and thus could be used as factory parts in the chemical array of sealants, gaskets or pipes, for example. Simons invented a method for the large-scale, industrial production of fluorocarbons. In September 1948, he presented a series of papers at a Fluorocarbon Symposium by the American Chemical Society. On 29 November 1948 he filed an application to patent the electrochemical process of making fluorine-containing carbon compounds with two others from the Minnesota Mining & Manufacturing Company, St. Paul, Minnesota, which he received on 22 August 1950.

Work led by Kabanov has recently shown that some of these polymers, originally thought to be inert carrier molecules, have a very real effect on biological systems independently of the drug they are transporting. The poloxamers have been shown to incorporate into cellular membranes affecting the microviscosity of the membranes. The polymers seem to have the greatest effect when absorbed by the cell as an unimer rather than as a micelle. Effect on multi drug resistant cancer cells Poloxamers have been shown to preferentially target cancer cells, due to differences in the membrane of these cells when compared to noncancer cells.

There is usually little if any response to shortwave ultraviolet, in contrast to many diamond simulants. Similarly, because most diamond simulants are artificial, they tend to have uniform properties: in a multi- stone diamond ring, one would expect the individual diamonds to fluoresce differently (in different colors and intensities, with some likely to be inert). If all the stones fluoresce in an identical manner, they are unlikely to be diamond. Most "colorless" diamonds are actually tinted yellow or brown to some degree, whereas some artificial simulants are completely colorless—the equivalent of a perfect "D" in diamond color terminology.

On 14 October 1940 at Chapel Street, Coventry, Second Lieutenant Campbell along with Sergeant Michael Gibson and Sappers W. Gibson, R. Gilchrest, A. Plumb, R.W. Skelton and Driver E.F.G. Taylor were tasked to deal with a unexploded bomb. The sappers spent almost four days uncovering the bomb which was found to contain a very damaged delayed-action fuse mechanism which could not be removed in situ. Though any electrical charge within the fuse was thought to have dissipated, Campbell still applied a discharge tool. On the 17 October 1940, Campbell, believing the bomb to be inert ordered it to be moved.

In the nano-synthesis process, material is first heated up to evaporation in induction plasma, and the vapours are subsequently subjected to a very rapid quenching in the quench/reaction zone. The quench gas can be inert gases such as Ar and N2 or reactive gases such as CH4 and NH3, depending on the type of nanopowders to be synthesized. The nanometric powders produced are usually collected by porous filters, which are installed away from the plasma reactor section. Because of the high reactivity of metal powders, special attention should be given to powder pacification prior to the removal of the collected powder from the filtration section of the process.

Although Fluorinert was intended to be inert, the Lawrence Livermore National Laboratory discovered that the liquid cooling system of their Cray-2 supercomputers decomposed during extended service, producing some highly toxic perfluoroisobutene.Kwan, J. Kelly, R, Miller G. Presentation at the American Industrial Hygiene Conference, Salt Lake City, UT, May 1991 Catalytic scrubbers were installed to remove this contaminant. The science-fiction film The Abyss (1989) depicted an experimental liquid-breathing system, in which the use of highly oxygenated Fluorinert enabled a diver to descend to great depths. While several rats were shown actually breathing Fluorinert, scenes depicting actor Ed Harris using the fluid-breathing apparatus were simulated.

After the legal manufacture of the drug ended in the United States in 1982, underground laboratories in Mexico continued the illegal manufacture of methaqualone throughout the 1980s, continuing the use of the "714" stamp, until their popularity waned in the early 1990s. Drugs purported to be methaqualone are in a significant majority of cases found to be inert, or contain diphenhydramine or benzodiazepines. Illicit methaqualone is one of the most commonly used recreational drugs in South Africa. Manufactured in clandestine, often in unsanitary conditions in India, it comes in tablet form, but is smoked with marijuana; this method of ingestion is known as "white pipe".

Uranium tailings can retain up to 85% of the ore's original radioactivity. If uranium tailings are stored aboveground and allowed to dry out, the radioactive sand can be carried great distances by the wind, entering the food chain and bodies of water. The danger posed by such sand dispersal is uncertain at best given the dilution effect of dispersal. The majority of tailing mass will be inert rock, just as it was in the raw ore before the extraction of the uranium, but physically altered, ground up, mixed with large amounts of water and exposed to atmospheric oxygen, which can substantially alter chemical behaviour.

The yield of 15 megatons was triple that of the 5 Mt predicted by its designers. The cause of the higher yield was an error made by designers of the device at Los Alamos National Laboratory. They considered only the lithium-6 isotope in the lithium-deuteride secondary to be reactive; the lithium-7 isotope, accounting for 60% of the lithium content, was assumed to be inert. It was expected that the lithium-6 isotope would absorb a neutron from the fissioning plutonium and emit an alpha particle and tritium in the process, of which the latter would then fuse with the deuterium and increase the yield in a predicted manner. Lithium-6 indeed reacted in this manner.

Totem cabinets are made to be inert but also harmonically expressive, which means creating synergy between veneers, stains, and lacquers. Lock mitred, monocoque construction is an intricate woodworking method in which a zigzag pattern is cut into the ends of panels so they provide substantially more surface area on each joining piece and in turn have more area to grip and physically lock together in a much stronger fashion. They are finally glued together at a 90-degree angle, making the Totem cabinet up to 5 times stiffer than conventional cabinet assembly. The medium density fiberboard (MDF) used is a unique recipe with a density of 90% on the exterior speaker side and 65% towards the interior.

This allows aluminium to burn with a large release of heat in substances that one normally considers to be inert, such as carbon dioxide and water. However, aluminium combustion is normally hindered by the presence of a durable oxide layer that forms on the surface of aluminium particles, requiring significant heat to overcome. Additionally, aluminium oxide condenses out of the exhaust stream at high temperature, leaving it (and its heat of condensation) unable to contribute to expansion unless there is another gas present to function as a working fluid. This generally has relegated aluminium's role in rocketry to that of being an additive to solid rocket propellants, increasing their density and combustion temperature and stabilizing the burn.

An elegant demonstration of the power of asymmetric organocatalytic aldol reactions was disclosed by MacMillan and coworkers in 2004 in their synthesis of differentially protected carbohydrates. While traditional synthetic methods accomplish the synthesis of hexoses using variations of iterative protection-deprotection strategies, requiring 8–14 steps, organocatalysis can access many of the same substrates using an efficient two-step protocol involving the proline-catalyzed dimerization of alpha-oxyaldehydes followed by tandem Mukaiyama aldol cyclization. center The aldol dimerization of alpha-oxyaldehydes requires that the aldol adduct, itself an aldehyde, be inert to further aldol reactions. Earlier studies revealed that aldehydes bearing alpha-alkyloxy or alpha- silyloxy substituents were suitable for this reaction, while aldehydes bearing Electron-withdrawing groups such as acetoxy were unreactive.

Computer tomography (a) and electron micrograph (b) of the Ti foam made with saccharose as a space holder, showing two types of pores in titanium foam The selection of the space-holder is one of the most crucial steps because it defines many of the properties of the resulting foam, including cell shape, cell size and macroporosity. The space-holder should be inert and represent the size and shape of the desired pores. The porosity may be adjusted anywhere between 50 and 85% without the filler material becoming a part of the resultant foam. It is also important to select a spacer that has limited or no solubility in titanium, as this incorporation will affect the mechanical properties of the resulting foam.

Natural lithium is a mixture of lithium-6 and lithium-7 isotopes (with 7.5% of the former). The enriched lithium used in Bravo was nominally 40% lithium-6 (the balance was the much more common lithium-7, which was incorrectly assumed to be inert). The fuel slugs varied in enrichment from 37 to 40% in Li, and the slugs with lower enrichment were positioned at the end of the fusion-fuel chamber, away from the primary. The lower levels of lithium enrichment in the fuel slugs, compared with the ALARM CLOCK and many later hydrogen weapons, were due to shortages in enriched lithium at that time, as the first of the Alloy Development Plants (ADP) started production by the fall of 1953.

Pitt took part in the controversy which followed the establishment of a dispensary by the College of Physicians in 1696. He published in 1702 The Craft and Frauds of Physick exposed, dedicated to Sir William Prichard, president, and to the governors of St. Bartholomew's Hospital, and written to show the low cost of the useful drugs, the worthlessness of some expensive ones, and the dangers of taking too much physic. Sarsaparilla, which for more than a hundred years later was a highly esteemed drug, was detected by Pitt to be inert; and he condemned the use of bezoar, of powder of vipers, of mummy, and of many other once famous therapeutic agents, on the ground that accurate tests proved them of no effect. A second and third edition appeared in 1703.

The discovery that a hormone can influence phosphoinositide metabolism was made by Mabel R. Hokin (1924–2003) and her then husband Lowell E. Hokin in 1953, when they discovered that radioactive 32P phosphate was incorporated into the phosphatidylinositol of pancreas slices when stimulated with acetylcholine. Up until then phospholipids were believed to be inert structures only used by cells as building blocks for construction of the plasma membrane. Over the next 20 years, little was discovered about the importance of PIP2 metabolism in terms of cell signaling, until the mid-1970s when Robert H. Michell hypothesized a connection between the catabolism of PIP2 and increases in intracellular calcium (Ca2+) levels. He hypothesized that receptor-activated hydrolysis of PIP2 produced a molecule that caused increases in intracellular calcium mobilization.

Members of the proposed genus Scalindua are anaerobic anammox (ammonium oxidizing) bacteria. The ammonium- oxidizing reaction composes a significant part of the global nitrogen cycle; by some estimates it is the cause of up to 50% of total nitrogen turnover in marine environments. It consists of the oxidization of ammonium using nitrite as an electron acceptor (both are fixed nitrogen) and subsequent generation of nitrogen gas: “NH4+ \+ NO2− = N2 \+ 2H2O (ΔG° = -357 kj mol-1)” This reaction uses nitrite (NO2−) as a terminal electron acceptor to produce nitric oxide (NO), which is then combined with ammonium (NH4+) to produce the intermediate hydrazine (N2H4) and water (H2O). Hydrazine, a very reactive molecule also used for rocket fuel, is then oxidized into nitrogen gas (N2). The half reactions may be represented as: “NO2− \+ 2H+ \+ e− = NO + H2O (E° = +0.38V) NO + NH4+ \+ 2H+ \+ 3e− = N2H4 \+ H2O (E° = +0.06V) Mechanism of Ammonium Oxidation N2H4 = N2 \+ 4H+ \+ 4e− (E° = -0.75V)” This metabolic pathway occurs anaerobically, something that was once considered impossible as ammonium was thought to be inert in the absence of oxygen.
