Prediction and classification for GPCR sequences based on ligand specific features [PDF]

open access: yes, 2006
Functional identification of G-Protein Coupled Receptors (GPCRs) is one of the current focus areas of pharmaceutical research. Although thousands of GPCR sequences are known, many of them are orphan sequences (the activating ligand is unknown). Therefore,

Selective removal of H2S from sour gases with microporous membranes. Part II. A liquid membrane of water-free tertiary amines [PDF]

open access: yes, 1993
In the present study the application of a liquid membrane for selective removal of H2S from gases also containing CO2 was investigated. The liquid membrane was filled with pure methyl-di-ethanol-amine (MDEA). A theoretical model was developed to describe:

Deactivation of gold(I) catalysts in the presence of thiols and amines – characterisation and catalysis [PDF]

open access: yes, 2013
Thiols and amines, which are common heteroatom nucleophiles in gold-catalysed reactions, are known to dampen the reactivity of gold catalysts. In this article, the identity and activity of gold(I) catalysts in the presence of thiols and amines is ...

Chiral molecule adsorption on helical polymers [PDF]

open access: yes, 2003
We present a lattice model for helicity induction on an optically inactive polymer due to the adsorption of exogenous chiral amine molecules. The system is mapped onto a one-dimensional Ising model characterized by an on-site polymer helicity variable ...

How cinchona alkaloid-derived primary amines control asymmetric electrophilic fluorination of cyclic ketones. [PDF]

open access: yes, 2014
The origin of selectivity in the α-fluorination of cyclic ketones catalyzed by cinchona alkaloid-derived primary amines is determined with density functional calculations.

Efficacy of different antifouling treatments for seawater cooling systems [PDF]

open access: yes, 2010
In an industrial seawater cooling system, the effects of three different antifouling treatments, viz. sodium hypochlorite (NaClO), aliphatic amines (Mexel1432) and UV radiation, on the characteristics of the fouling formed were evaluated.
