Talanta. 1967 Oct;14(10):1163-8.

Some aliphatic amines have been titrated enthalpimetrically. The heats of neutralization have been calculated from the results and correlated with the basicity of the amines and the number of hydroxyl and amine groups present. The titration curves were all...

Amine borate catabolism by bacteria isolated from contaminated metal-working fluids.

Sherburn RE, Large PJ.
PMID: 10594706
J Appl Microbiol. 1999 Nov;87(5):668-75. doi: 10.1046/j.1365-2672.1999.00906.x.

Four bacterial strains (tentatively identified as strains of Aeromonas, Pseudomonas, Flavobacterium and Bacillus) isolated from contaminated metal-working fluids were assayed for the capacity to utilize the borate derivatives of monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA). Two of these...

A series of novel precursors for MOCVD of metallic copper have been synthesized and structurally characterized. These precursors are composed of Cu(hfacac)(2), which serves as a volatile source of Cu, and amino alcohols, which act as reductants and anchor...

Effect of Ethanolamines on the Electroless Deposition of Copper on Functionalized Organic Surfaces.

Langmuir : the ACS journal of surfaces and colloids

Ellsworth AA, Walker AV.
PMID: 29526106
Langmuir. 2018 Apr 10;34(14):4142-4149. doi: 10.1021/acs.langmuir.7b03725. Epub 2018 Mar 27.

Electroless deposition (ELD) is widely used in industry to deposit metals because it is inexpensive and compatible with organic materials. The deposition rate and deposited film properties critically depend on the reducing agent, complexing agent, and bath pH and...

Ceria nanoparticles as heterogeneous catalyst for CO2 fixation by omega-aminoalcohols.

Chemical communications (Cambridge, England)

Juárez R, Concepción P, Corma A, García H.

Chem Commun (Camb). 2010 Jun 21;46(23):4181-3. doi: 10.1039/c001955k. Epub 2010 Apr 21.

In contrast to gamma-Al(2)O(3), TiO(2), ZrO(2), MgO and Y(2)O(3), CeO(2) is a reusable catalyst for the reaction of CO(2) with omega-aminoalcohols to form cyclic carbamates; the highest yield (68%) was obtained for the preparation of N-alkyl 1,3-oxazolidin-2-ones from N-alkyl...

Low-Temperature Reductive Aminolysis of Carbohydrates to Diamines and Aminoalcohols by Heterogeneous Catalysis.

Angewandte Chemie (International ed. in English)

Pelckmans M, Vermandel W, Van Waes F, Moonen K, Sels BF.
PMID: 28892238
Angew Chem Int Ed Engl. 2017 Nov 13;56(46):14540-14544. doi: 10.1002/anie.201708216. Epub 2017 Oct 13.

Short amines, such as ethanolamines and ethylenediamines, are important compounds in today's bulk and fine chemicals industry. Unfortunately, current industrial manufacture of these chemicals relies on fossil resources and requires rigorous safety measures when handling explosive or toxic intermediates....

Carbamate stabilities of sterically hindered amines from quantum chemical methods: relevance for CO2 capture.

Chemphyschem : a European journal of chemical physics and physical chemistry

Gangarapu S, Marcelis AT, Zuilhof H.
PMID: 24203852
Chemphyschem. 2013 Dec 02;14(17):3936-43. doi: 10.1002/cphc.201300820. Epub 2013 Nov 06.

The influence of electronic and steric effects on the stabilities of carbamates formed from the reaction of CO2 with a wide range of alkanolamines was investigated by quantum chemical methods. For the calculations, B3LYP, M11-L, MP2, and spin-component-scaled MP2...

The Ability of Metabolomics to Discriminate Non-Small-Cell Lung Cancer Subtypes Depends on the Stage of the Disease and the Type of Material Studied.

Cancers

Identification of the NSCLC subtype at an early stage is still quite sophisticated. Metabolomics analysis of tissue and plasma of NSCLC patients may indicate new, and yet unknown, metabolic pathways active in the NSCLC. Our research characterized the metabolomics...

Fatty acid composition of milk phospholipids. II. Sheep, Indian buffalo and human milks.

Lipids

Morrison WR, Smith LM.
PMID: 17805746
Lipids. 1967 Mar;2(2):178-82. doi: 10.1007/BF02530919.

Phospholipids were isolated from sheep, Indian buffalo, and human milks, and their fatty acid compositions determined by gas chromatography.
