Are you looking for SOLUTION OF RHODIUM SULFATE (Ⅱ)?

Rhodium sulfate exists as a whitish-red or translucent liquid. Its molecular weight is 566.05. At the molecular level, it's composed of two rhodium atoms bonded to three sulfate molecules, which themselves are composed of a sulfate atom bonded to four oxygen atoms.
The specification describes novel rhodium sulfate complex solutions which have a minimum of metal to metal complexing and are mostly complexed through the sulfate groups. Use of these solutions as electrolytes for plating rhodium results in electroplated layers with improved brightness and reduced stress.
Rhodium plated electrodes are used in the soda industry for electrolysis of salt water, and for electrodes for domestic water treatment. Rhodium plating is used widely in the jewelry industry. In the electronics industry, rhodium plating is used for electrical contacts in, e.g., ferreed switches.
The rhodium sulfate complex that is formed by standard hydrolysis is shown in FIG. 1. It is characterized by rhodium-rhodium bonding as well as bonding through the sulfate groups. By controlling the hydrolysis reaction, as described below, the rhodium to rhodium bonding is essentially eliminated and the rhodium sulfate complexes as shown in FIG. 2, with a simple bridge between the sulfate groups.
The technique for preparing this rhodium sulfate complex is described by the flow chart of FIG. 3. Rhodium is refluxed in sulfuric acid as shown to produce a rhodium sulfate concentrate. Rhodium sulfate is then neutralized with a mild base, in this case, ammonium hydroxide, by the two procedures shown in the figure. The first, Process A, is the conventional hydrolysis in which the acid and base are simply combined, with both reagents typically at room temperature. The neutralization reaction is exothermic, and the solution characteristically heats to a temperature substantially above room temperature. In the process of the invention, Process B, the neutralization reaction is controlled by cooling the rhodium sulfate to a temperature below room temperature, e.g., below 20° C., and maintaining the reagent mixture at a temperature below 25° C. during the reaction. This can be achieved by actively cooling the reaction vessel. In practice, it was found that using a jacketed reaction vessel, and flowing cool or cold water, e.g. water at 10° C., through the vessel jacket, the temperature of the reagent mixture can be controlled to a temperature below 25° C. Without active cooling during the reaction, as described above, the reagent mixture heats to a temperature above 25° C.

Cholesteryl acetate was a flowing liquid exhibiting optical properties previously attributed only to crystals. The discovery brought into question the belief of the time that only three states of matter could exist (liquid, solid, and gas). More recently, liquid crystals such as cholesteryl acetate have come to be used in cosmetics, wrist watches, thermometers, propane tank volume indicators, video displays, and in the "mood rings" of the late 1970s fad.
Synthesis of cholesteryl acetate from cholesterol involves heating the cholesterol in a solution of acetic acid and acetic anhydride. Although synthesized in the laboratory and on a commercial scale, cholesteryl acetate exists as a naturally occurring substance as well. For example, it is found as one of the three cholesterol esters composing the outer cuticle layer lipid coating of the brown dog tick
Cholesteryl acetate disrupts the packing order of the DMPC acyl chains from 0 to ca. 35 mol% cholesterylacetate. As the concentration of cholesterylacetate is increased from ca. 14 to ca. 35 mol% the DMPC acyl chains become more ordered and cholesterylacetate appears to form a crystalline phase that remains inn suspension with the lecithin. As more cholesterylacetate is added, these crystalline regions become larger and begin to form a precipitate which is structurally identical to those particles which remain in suspension.

What is Sodium tetrachloroaurate (III) dihydrate

Sodium tetrachloroaurate (III) dihydrate
CAS Number: 13874-02-7
Molecular Weight: 397.80
Molecular Formula: NaAuCl4•2H2O
Physical Appearance: Yellow to gold powder or crystals
Description
Sodium tetrachloroaurate (III) dihydrate is a water/alcohol soluble Au(I) complex that is formed from NaAuCl4. It has potential for application in chemotherapeutics.
Sodium Tetrachloroaurate(III) Dihydrate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.
Sodium is a metallic element with a symbol Na, and atomic number 11. It is a soft, silvery-white, highly reactive metal and is a member of the alkali metals within "group 1". It has one stable isotope, 23Na.
Elemental sodium was first isolated by Humphry Davy in 1807 by passing an electric current through molten sodium hydroxide. Elemental sodium does not occur naturally on Earth, because it quickly oxidizes in air and is violently reactive with water, so it must be stored in a non-oxidizing medium, such as a liquid hydrocarbon. The free metal is used for some chemical synthesis, analysis, and heat transfer applications.
Characteristics
At room temperature, sodium metal is soft enough that it can be cut with a knife. In air, the bright silvery luster of freshly exposed sodium will rapidly tarnish. The density of alkali metals generally increases with increasing atomic number, but sodium is denser than potassium. Sodium is a fairly good conductor of heat.
Sodium changes color at high pressures, turning black at 1.5 megabar, becoming a red transparent substance at 1.9 megabar, and is predicted to become clearly transparent at 3 megabar. The high pressure allotropes are insulators and take the form of sodium electride.

What is Kinetin?

Kinetin is a kind of cytokinin, a class of plant hormone that promotes cell division. Kinetin was originally isolated by Miller and Skoog et al. as a compound from autoclaved herring sperm DNA that had cell division-promoting activity. It was given the name kinetin because of its ability to induce cell division, provided that auxin was present in the medium. The story of the discovery of kinetin is a fascinating example of the twists and turns of scientific discovery. Kinetin is often used in plant tissue culture for inducing formation of callus (in conjunction with auxin) and to regenerate shoot tissues from callus (with lower auxin concentration).
For a long time, it was believed that kinetin was an artifact produced from the deoxyadenosine residues in DNA, which degrade on standing for long periods or when heated during the isolation procedure. Therefore, it was thought that kinetin does not occur naturally, but, since 1996, it has been shown by several researchers that kinetin exists naturally in the DNA of cells of almost all organisms tested so far, including human and various plants. The mechanism of production of kinetin in DNA is thought to be via the production of furfural — an oxidative damage product of deoxyribose sugar in DNA — and its quenching by the adenine base's converting it into N6-furfuryladenine, kinetin.
Since 1994, Kinetin has been thoroughly tested for its powerful anti-aging effects in human skin cells and other systems. At present, kinetin is one of the widely used components in numerous skin care cosmetics and cosmeceuticals, such as Valeant products kinerase . There are some reports published on other biological effects of kinetin in human beings, for example its effects as anti-platelet aggregation factor reducing thrombosis formation. In addition, it has been shown to be capable of correcting RNA mis-splicing in the disease of familial dysautonomia, in which exon 20 of IKBKAP is skipped instead of included in the disease, leading to insufficient levels of IKBKAP protein product as a result of frame-shift-induced nonsense-mediated decay.
Kinetin stimulates skin cells at the deepest layers of skin's surface to keep them healthier longer. It is Kinerase's signature ingredient that has successfully transformed women's skin for more than 10 years, visibly improving wrinkles, tone and texture.
