We have investigated the effects of molecular organization in mixed Langmuir-Blodgett (LB) films of 11-(9-carbazolyl)undecanoic acid (CUA) and palmitic acid on the fluorescence characteristics of these films. The fluorescence from carbazolyl chromophores was quenched rapidly at the initial stage...

Crystal structures are reported of cycloamylose containing 26 d-glucose residues (CA26, cyclohexaicosaose, C156H260O130) in complexes with undecanoic acid (CA26·2C10H21COOH·34.95H2O, orthorhombic P212121, one CA26 and two bound undecanoic acids F1 and F2 in the asymmetric unit, resolution 0.95...

In this paper, we discuss the use of 10-undecanoic acid monolayers on silicon dioxide films in a novel electron beam patterning process. The monolayers are locally fixed by electron exposure and subsequently act as an oxide etch initiator in HF vapor, thereby allowing the oxide to be patterned. ...

In this study, the surface charge properties of perfluorinated C8 (PerfluoroC8) and undecanoic acid (UDA) modified silica hydride stationary phases have been investigated. The zeta potential values of these stationary phases were measured in aqueous/acetonitrile mobile phases of different pH, bu...

Vibrio harveyi are Gram-negative marine luminescent bacteria and most of them are multi-drug resistant pathogens. The incidence of biofilm mediated antibiotic resistance stresses the quest for novel therapeutics to treat luminescent vibriosis in aquaculture. This study intended to explore the co...

Five α-linked diglucosyl disaccharides (isomaltose, nigerose, kojibiose, maltose, and α,β-trehalose) and two trisaccharides (isomaltotriose and panose) were produced in 90% aqueous solutions of 2-methoxyethyl ether, 2-ethoxyethyl ether, or triethylene glycol dimethyl ether by glucoamylase-cat...

A detailed chemical kinetics model has been developed to elucidate the auto-ignition behavior of diethyl ether (DEE) under conditions relevant for internal combustion engines. The present model is composed of a C0–C4 base module from literature and a DEE module. For the low-temperature oxidatio...

1H-Pyrazolo[4,3-d]pyrimidines are a class of potent and selective second generation phosphodiesterase 5 (PDE5) inhibitors. This work explores the potency, selectivity and efficacy of 1-(2-ethoxyethyl)-1H-pyrazolo[4,5-d]pyrimidines as PDE5 inhibitors resulting in the advancement of a clinical can...

Ether groups are well-known for their unique contribution to low viscosity and high conductivity, hence ether-functionalized ionic liquids (EFILs) have been widely studied and successfully employed in various applications. Three EFILs 1-(2-methoxyethyl)-3-methylimidazolium chloride, 1-(2-ethoxye...

As part of a systematic study on thermodynamic properties for aqueous solution of alkoxyethanols, this paper reports data of densities and viscosities for aqueous solution of tetraethylene glycol monomethyl ether (CH3(OCH2CH2)4OH) as a function of composition at T = (293.15, 303.15, 313.15, 323....

As a continuation of thermodynamic study on aqueous solution of glycol ether, this paper reports new measurements of densities and viscosities for the binary liquid mixture of ethylene glycol monomethyl ether (CH3O(CH2)2OH) + water as a function of composition at T = (293.15, 303.15, 313.15, 323...

The solubility of methane in triethylene glycol monomethyl ether (TEGMME) has been measured at 40, 70 and 100 °C at pressures up to 8.4 MPa. The solubility data obtained are compared with those of methane in n-formyl morpholine, sulfolane and methanol. The results were correlated with the Peng ...

This paper reports new measurements of densities and viscosities for the binary liquid mixture of triethylene glycol monomethyl ether CH3O(CH2)2O(CH2)2O(CH2)2OH + water as a function of composition at T = (293.15, 303.15, 313.15, 323.15, 333.15) K under atmospheric pressure. Densities were deter...

The thermodynamic functions of activation for viscous flow have been evaluated from the dynamic viscosity values of binary mixtures considering Eyring's transition state theory. Kinematic viscosities and densities of binary mixtures containing triethylene glycol monomethyl ether + (2-propan...

Properties of di(triethylene glycol monomethyl ether) squarate relevant to conjugation of carbohydrates to proteins have been reinvestigated and compared with those of dimethyl squarate. It is concluded that the commercially available, crystalline dimethyl squarate remains the most convenient an...

The formate–nitrite transporter family is composed of integral membrane proteins that possess six to eight α-helical transmembrane domains. Genes encoding these proteins are observed widely in prokaryotic genomes as well as certain groups of lower eukaryotes. Thus far, no structural informatio...

The oxidation of methyl and n-octyl α-d-glucopyranoside to methyl and n-octyl α-d-glucopyranosiduronate with molecular oxygen over a graphite-supported platinum catalyst was investigated. An increase of the length of the n-alkyl substituent from methyl to n-octyl resulted in a ten-fold decreas...

Formaldehyde dehydrogenase (FaldDH) is used as a catalyst to reduce formate to formaldehyde in a cascade reaction to convert CO2 to methanol. This enzyme, however, has low activity and is sensitive to substrate/product concentration and pH. To improve the performance of FaldDH, it can be immobil...

In this study, the anion exchange reaction of an organic cation chloride with excess KHCO2 to synthesize formate-based ionic liquids (ILs) was performed in water, and the water-miscible IL products were easily obtained via salting-out phase separation caused by the excess KHCO2. According to the...

The decomposition of 1-decanol and decanal in the presence of hydrogen by using Ni- and H-ZSM-5 embedded within a silica binder was investigated. Temperatures and pressures for the decanol decomposition ranged from 572 to 666 K and 0.57 to 1.45 MPa, whereas for decanal the ranges were 622 to 722...
