Erbium oxide (CAS 12061-16-4)
Erbium oxide (CAS 12061-16-4)
The applications of Er2O3 are varied due to their electrical, optical and photoluminescence properties. Nanoscale materials doped with Er3+ are of much interest because they have special particle-size-dependent optical and electrical properties. Erbium oxide doped nanoparticle materials can be dispersed in glass or plastic for display purposes, such as display monitors. The spectroscopy of Er3+ electronic transitions in host crystals lattices of nanoparticles combined with ultrasonically formed geometries in aqueous solution of carbon nanotubes is of great interest for synthesis of photoluminescence nanoparticles in ‘green’ chemistry. Erbium oxide is among the most important rare earth metals used in biomedicine. The photoluminescence property of erbium oxide nanoparticles on carbon nanotubes makes them useful in biomedical applications. For example, erbium oxide nanoparticles can be surface modified for distribution into aqueous and non-aqueous media for bioimaging. Erbium oxides are also used as gate dielectrics in semi conductor devices since it has a high dielectric constant (10–14) and a large band gap. Erbium is sometimes used as a coloring for glasses and erbium oxide can also be used as a burnable neutron poison for nuclear fuel.

Ethanolamine (CAS 141-43-5)
Ethanolamine (CAS 141-43-5)
Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is an organic chemical compound with the formula HOCH2CH2NH2 (C2H7NO). The molecule is bifunctional, containing both a primary amine and a primary alcohol. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. Its derivatives are widespread in nature; e.g., lipids, as precursor of a variety of N-acylethanolamines (NAEs), that modulate several animal and plant physiological processes such as seed germination, plant–pathogen interactions, chloroplast development and flowering, as well as precursor, combined with arachidonic acid (C20H32O2; 20:4, ω-6), to form the endocannabinoid anandamide (AEA: C22H37NO2; 20:4, ω-6).
The ethanolamines comprise a group of amino alcohols. A class of antihistamines is identified as ethanolamines, which includes carbinoxamine, clemastine, dimenhydrinate, Chlorphenoxamine, diphenhydramine and doxylamine.

Ethyl acetate (CAS 141-78-6)
Other names: Ethyl acetate, ethyl ethanoate
Description:
Ethyl acetate is an ethyl etheric acid in the form of a combustible colorless volatile liquid substance with a sharp smell of fruit. There are no mechanical impurities. It is a moderately polar solvent product with the properties of esters. The solution is supplied in methylcarbinol, ethyl ether, benzene, methylene chloride, methylbenzene and some other organic solvents. In water, the dissolution is weaker. Ethyl acetate has a solvent effect on cellulose esters, oil-based resin lacquers, fats and waxes.
Production on an industrial scale occurs during the reaction of ethanol and acetic acid. It is also possible to process ethanol with carbomethylene or synthesize it from acetic aldehyde in the presence of an aluminum alkoxide catalyst.

Ethylene glycol (CAS 107-21-1)
Ethylene glycol (1,2-dioxane, glycol, ethanediol-1,2) is a sweet-tasting, odorless, colorless, hygroscopic oily liquid. It is obtained by wetting ethylene in the presence of phosphoric or sulfuric acids. Ethylene glycol mixes well with water and alcohol. It has high boiling points and low freezing temperatures, which is why it is widely used as a heat carrier in heating and cooling systems. The crystallization temperature of the concentrate is higher than that of aqueous glycol solutions, therefore it must be diluted with distilled water before use.

Eucalyptus oil
Eucalyptus oil
Eucalyptus oil is a generic name for distilled oil that comes from the leaves of the Eucalyptus genus of the Myrtaceae plant family, native to Australia and cultivated worldwide. Eucalyptus oil has been widely used as a pharmaceutical agent, antiseptic, repellent, aroma, fragrance and industrial use. The leaves of selected eucalyptus species are steam distilled to extract eucalyptus oil.
