A device for automatically maintaining any desired concentration of triethylene or propylene glycol vapor in air is described. It can also be used to measure very rapidly the glycol content of room air. This instrument should greatly facilitate tests of the efficacy of glycol vapors in preventing air-borne infections.

The objective of this study was to evaluate the effects of Lriethylc}ne glyco] (TEG) and triethylene glycol monomethacrylate (TEG)vlA) solutions as dentin primers on dentin bonding. To this end, wall-Lo-wall polyTnerization contraction gap vL,idth of a resin cornposite ill a cylindrical dentin eavity and shear bond strength to a flat dentin surface were measured. Dentin was pretreated with an e...

Magnetite (Fe3O4) nanoparticles were synthesized by coprecipitation route. Coprecipitation is a simple, reproducible and accessible technique relying on the coprecipitation of Fe2+ and Fe3+ cations by NaOH as base at low temperature (~80 °C). In this work, the role of different solvents (H2O, ethylene glycol, diethylene glycol, triethylene glycol) on phase, structure, microstructure and magneti...

The objective of this study was to evaluate the effects of triethylene glycol (TEG) and triethylene glycol monomethacrylate (TEGMA) solutions as dentin primers on dentin bonding. To this end, wall-to-wall polymerization contraction gap width of a resin composite in a cylindrical dentin cavity and shear bond strength to a flat dentin surface were measured. Dentin was pretreated with an experimen...

Inherently chiral biscalix[4]arenes have been designed and synthesized by covalently assembling two calix[4]arene building blocks in a 1,3-position linking with 1,2-position pattern at the lower rims via two triethylene glycol bridges.

polyvinyl butyral (pvb) was synthesized by condensation reaction of polyvinyl alcohol (pva) with butanal in aqueous medium containing an effective emulsifier and an inorganic acid as catalyst. the product was characterized by, ir, tg and dtg techniques. percentage of vinyl alcohol groups in the pvb was determined by a chemical method according to a standard method. some clear and soft film samp...

Insomnia is the most common sleep complaint which occurs due to difficulty in falling asleep or maintaining it. Most of currently available drugs for insomnia develop dependency and/or adverse effects. Hence natural therapies could be an alternative choice of treatment for insomnia. The root or whole plant extract of Ashwagandha (Withania somnifera) has been used to induce sleep in Indian syste...

The biocidal and biostatic activities of seven glycol monoalkyl ether compounds were evaluated as part of an effort to find an improved anti-icing additive for jet aircraft fuel. Typical fuel contaminants, Cladosporium resinae, Gliomastix sp., Candida sp., Pseudomonas aeruginosa, and a mixed culture containing sulfate-reducing bacteria were used as assay organisms. Studies were carried out over...

Two kinds of fluorinated polymers were synthesized: an acrylate polymer having a fluorinated triethylene glycol as a pendant group (2a) and a fluoroalkyl acrylate polymer (2b). The contact angle of these fluorinated polymers against water, non-fluorinated alcohols and fluorinated alcohols were evaluated. As compared with the fluoroalkyl polymer (2b), fluoroethylene glycol polymer (2a) showed sm...
