J Dent (Tehran). 2010;7(2):71-6. Epub 2010 Jun 30.

OBJECTIVE: The aim of the present study was to evaluate the efficacy of two caries detector dyes in the diagnosis of dental caries.MATERIALS AND METHODS: Twenty extracted human posterior teeth without pulpal exposure were sectioned mesiodistally through the center...

Enhanced Controlled Transdermal Delivery of Ambroxol from the EVA Matrix.

Indian journal of pharmaceutical sciences

Cho CW, Kim DB, Cho HW, Shin SC.
PMID: 23325993
Indian J Pharm Sci. 2012 Mar;74(2):127-32. doi: 10.4103/0250-474X.103844.

To avoid the systemic adverse effects that might occur after oral administration, transdermal delivery of ambroxol was studied as a method for maintaining proper blood levels for an extended period. Release of ambroxol according to concentration and temperature was...

Dilatant effect enhancers for silica dispersions in poly(propylene glycols).

Journal of colloid and interface science

Orawiec M, Kaczorowski M, Rokicki G.
PMID: 29859455
J Colloid Interface Sci. 2018 Oct 15;528:301-308. doi: 10.1016/j.jcis.2018.05.097. Epub 2018 May 29.

Shear thickening fluids have found many applications in energy damping materials such as sports guards and liquid body armors. Therefore, an additive which could tailor the dilatant properties of such fluids without significantly affecting other properties, especially zero shear...

Basic poly(propylene glycols) as reference compounds for internal mass calibration in positive-ion matrix-assisted laser desorption/ionization mass spectrometry.

European journal of mass spectrometry (Chichester, England)

Gross JH.
PMID: 29183190
Eur J Mass Spectrom (Chichester). 2017 Dec;23(6):411-416. doi: 10.1177/1469066717726485. Epub 2017 Aug 16.

Basic poly(propylene glycols), commercially available under the trade name Jeffamine, are evaluated for their potential use as internal mass calibrants in matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry. Due to their basic amino endgroups Jeffamines are expected to deliver [M+H]

Ru-Containing Magnetically Recoverable Catalysts: A Sustainable Pathway from Cellulose to Ethylene and Propylene Glycols.

ACS applied materials & interfaces

Manaenkov OV, Mann JJ, Kislitza OV, Losovyj Y, Stein BD, Morgan DG, Pink M, Lependina OL, Shifrina ZB, Matveeva VG, Sulman EM, Bronstein LM.
PMID: 27484222
ACS Appl Mater Interfaces. 2016 Aug 24;8(33):21285-93. doi: 10.1021/acsami.6b05096. Epub 2016 Aug 11.

Biomass processing to value-added chemicals and biofuels received considerable attention due to the renewable nature of the precursors. Here, we report the development of Ru-containing magnetically recoverable catalysts for cellulose hydrogenolysis to low alcohols, ethylene glycol (EG) and propylene...

Reactive matrices for matrix-assisted laser desorption/ionization mass spectrometry of primary amines.

European journal of mass spectrometry (Chichester, England)

Zaikin VG, Borisov RS, Polovkov NY, Slyundina MS.
PMID: 26307721
Eur J Mass Spectrom (Chichester). 2015;21(3):403-11. doi: 10.1255/ejms.1353.

Some aromatic carbonyl compounds [2,4-dihydroxybenzaldehyde (2,4-DHBA), 2,5- dihydroxyacetophenone (DHAP), 2,3,5-trihydroxybenzaldehyde and 2,4-dinitrobenzaldehyde] were examined as potential reactive matrices for the analysis of mono-, di-, and polyamines by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS). Although all the above compounds...

Facile conversion of cis into trans oxane as liquid crystals.

Scientific reports

Dong Z, Fan P, Chen Q, Chen C.
PMID: 32332816
Sci Rep. 2020 Apr 24;10(1):6936. doi: 10.1038/s41598-020-63902-y.

Trans-oxanes are important liquid crystals. The commonly used techniques for the synthesis were to react 2-substituted propylene glycols with substituted formaldehydes. Such process produces toxic cis-oxanes, which are harmful to the environment. The cis to trans isomerization of wasted...

PPG-Terminated Tetra-Carbamates as the Toughening Additive for Bis-A Epoxy Resin.

Polymers

Zhang M, Chen M, Ni Z.
PMID: 31546854
Polymers (Basel). 2019 Sep 19;11(9). doi: 10.3390/polym11091522.

We synthesized PPG-terminated tetra-carbamates as a new toughening additive for epoxy thermosets through facile addition reaction of hexamethylene diisocyanate (HDI) with poly(tetra-methylene glycols) (PTMG) and poly(propylene glycols) (PPG). The effects of prepared tetra-carbamates on the rheological behavior of neat...

Trace determination of glycols by HPLC with UV and electrospray ionization mass spectrometric detections.

Analytical chemistry

Holčapek M, Virelizier H, Chamot-Rooke J, Jandera P, Moulin C.
PMID: 21662779
Anal Chem. 1999 Jul 01;71(13):2288-93. doi: 10.1021/ac981087y.

A high-performance liquid chromatography/mass spectrometry (HPLC/MS) method is developed for trace determination of glycols (ethylene glycol, 1,2- and 1,3-propylene glycols, and 2,3-butylene glycol) in water after derivatization with benzoyl chloride. Benzoyl esters of glycols are separated by microcolumn reversed-phase...
