PdML/Ni(1 1 1) and PdML/Co(1 1 1) surfaces were built via Pd atoms substituting the upper one layer atoms of Ni(1 1 1) and Co(1 1 1) surfaces, and have been discussed toward dimethyl oxalate (DMO) synthesis using density functional theory (DFT) calculation and micro-kinetic modeling, which were ...

The ketone C5F10O (C5-PFK) has been considered as substitute for SF6 in the past two years. And there are few reports on the interaction between C5-PFK and materials used in electrical equipment, which may have an influence on its long term behavior. In this paper, we explored the interaction be...

We have analyzed the effects of n-hexane, 1-hexanethiol, and 1-hexanol on the coupled respiration of rat liver mitochondria. Incubation of mitochondria with n-hexane, 1-hexanethiol and 1-hexanol resulted in a stimulation, at low concentrations, and an inhibition, at high concentrations, of the s...

Gold nanoparticles functionalized with mixtures of 1-hexanethiol and 4-mercaptophenol were investigated as chemiresistor sensors for use in aqueous solutions. X-ray photoelectron spectroscopy (XPS) studies confirmed that it was possible to form mixed ligand compositions on the surface of the nan...

Hydrogels of chitosan (CS) and glutaraldehyde (GA) were synthesized for tissue engineering applications by using a Schiff reaction. CS was reacted with GA (a cross-linker) at different concentrations, which were expressed as percentage of weight (2, 4, 6, 8 and 10 wt%). An evaluation was made of...

PurposeThe purpose of this in-vitro study was to evaluate the effect of 0.5% glutaraldehyde spray disinfection on surface wettability of vinyl polysiloxane and polyether impression materials.

Glutaraldehyde (GA) is the most common biocide used in unconventional oil and gas production. Photocatalytic degradation of GA in brine simulating oil and gas produced water using Ag/AgCl/BiOCl composite as a photocatalyst with visible light was investigated. Removal of GA at 0.1 mM in 200 g/L N...

High IgG-binding capacity of protein A affinity chromatography is crucial to its application in the antibody purification and autoantibody-associated disease treatment. An oriented immobilization strategy was used to covalently conjugate the recombinant protein A (rSpA) on the glutaraldehyde act...

Three β-glucosidases (Pectinex Ultra SP-L, Pectinex Ultra Clear and homemade preparation from Aspergillus niger) were immobilized using different strategies: ionic adsorption on aminated (MANAE)-agarose beads at pH 5, 7, and 9, followed by biocatalysts modification with glutaraldehyde, or on gl...

In this work, we present a method to improve the mechanical properties of CNF films by replacing the secondary hydrogen bonding in CNF films with glutaraldehyde (GA)-based covalent bonds using acidic catalysts. The CNF film treated with GA exhibits ∼180% higher tensile strength than that for th...

Electrospinning of PVA nanofiber-crosslinked by glutaraldehyde (GA) has been prepared and characterized. The PVA nanofibers have been produced by injecting 10 % w/v of PVA into electrospinning machine. The in-situ method has been used for crosslinking step for 4 hours using 0.5 M glutaraldehyde ...

Water generated by hydraulic fracturing for the production of oil and gas, commonly termed ‘produced water’, may contain residual organic compounds from the fracturing process or the subsurface formation. Biological treatment is a potential technology to remove residual organic compounds in pr...

Vapor-phase dehydration of 1,4- and 1,5-alkanediols was investigated over three scandium ytterbium mixed oxides, Sc2-xYbxO3 (x = 0.5, 1.0, and 1.5), to produce the corresponding unsaturated alcohols. In the dehydration of 1,5-pentanediol, Sc0.5Yb1.5O3 was more active than simple rare earth oxide...

For the first time, V modified Ir/SiO2 (Ir–VOx/SiO2) catalyst was used for the selective hydrogenolysis of tetrahydrofurfuryl alcohol (THFA) to 1,5-pentanediol and exhibited better performance than those of V modified other noble metal (Rh, Ru, Pt and Pd) catalysts. The optimum V/Ir atomic rati...

In this work, MoOx promoted Ir/SiO2 catalysts were prepared and used for the selective hydrogenolysis of tetrahydrofurfuryl alcohol (THFA) to 1,5-pentanediol in a continuous flow reactor. The effects of different noble metals (Ir, Pt, Pd, Ru, Rh), supports and Ir contents were screened. Among th...

1,5-Pentanediol (PeDO) is a biobased but less studied diol monomer for polyester synthesis. As one of a series of studies on PeDO-derived polyesters, two aliphatic-aromatic copolyesters, poly(pentylene succinate-co-terephthalate) (PPeST) and poly(pentylene adipate-co-terephthalate) (PPeAT), were...

Vapor-phase catalytic dehydration of 1,5-pentanediol (1,5-PDO) was investigated over monoclinic ZrO2 catalysts modified with basic oxides. An unsaturated alcohol, 4-penten-1-ol (4P1OL), was produced together with the formation of tetrahydropyran, δ-valerolactone, 1,4-pentadiene, pentanal, 1-pen...

Densities (ρ) and speed of sound (u) were measured in the binary liquid mixture of water and 1,5-pentanediol (PD) over the entire mixture composition range. Densitometric measurement were conducted in a temperature range of 278.15–333.15 K under atmospheric pressure, using a precise sealed vib...
