Phthalocyanines bearing coumarin moiety may exhibit interesting properties and also can soluble in organic solvents, easily. In this work, the phthalocyanine compounds bearing tetra-(3,6-dihexyl-7-oxy-4-methylcoumarin) units were synthesized and characterized. Firstly, the starting coumarin comp...

The thermodynamic parameters ΔG°, ΔH° and ΔS° for the formation of silver(I) mononuclear (AgL+) and polynuclear ([Ag2L]2+, [Ag3L2]3+) complexes with 1,4,7,10,13-pentaazatridecane (L=tetren) have been obtained in dimethyl sulfoxide (dmso) at 25°C and in an ionic medium of 0.1 mol dm−3. The...

The 3-mercaptopropionic acid (MPA) capping water-soluble ZnS:Mn2+ nanocrystal was successfully transferred into organic phase by using 1-dodecanethiol in presence of sodium hydroxide as phase-transfer agent. The MPA ligand can be replaced completely by the long chain thiol even in a single water...

In an effort to understand the effects of the molecular structures of self-assembled monolayers on the patterns formed by immobilized Au nanoparticles (AuNPs), we characterized and compared the morphologies and properties of AuNPs adsorbed onto self-assembled monolayers formed by 1-dodecanethiol...

The potential-controlled assembly of 1-dodecanethiol (DT) onto the polycrystalline gold surface from ethanolic solution was studied using in situ methods. The initial stage of DT adsorption and DT film nucleation were carried under potentiostatic control. The anodic polarization speeds up 1-dode...

Copper selenide nanocrystals with hierarchical morphologies were prepared using solution processed colloidal method by employing cost effective environmentally benign surfactants. The hierarchical morphologies such as interconnected nanoflakes, stacked hexagonal nanoplatelets and nanoflowers lik...

A 1-dodecanethiol-based phase-transfer protocol is developed for the extraction of noble metal ions from aqueous solution to a hydrocarbon phase, which calls for first mixing the aqueous metal ion solution with an ethanolic solution of 1-dodecanethiol, and then extracting the coordination compou...

As a typical semiconductor material, germanium has the potential to replace silicon for future-generation microelectronics, due to its better electrical properties. However, the lack of stable surface state has limited its extensive use for several decades. In this work, we demonstrated highly s...

Mesoporous hydroxyapatite with different pore diameters and pore volumes were synthesized by the self-assembly method using Cetyltrimethylammonium bromide (CTAB) as the cationic surfactant and 1-dodecanethiol as the pore expander at different micellization pHs, solvent types and surfactant conce...

Gold can be associated with hydrocarbons in hydrothermal gold deposits, but the near-absence of experimental data on gold-hydrocarbon interactions at hydrothermal conditions prevents a quantitative interpretation of this relationship. In this study, we investigate the ability of liquid hydrocarb...

Textile with Janus wetting properties, viz., one side super-nonwetting (abridged as SNW) and the other side super-wetting (SW), was fabricated via copper (Cu) deposition and subsequent chemical vapor deposition (CVD) of 1-dodecanethiol (DT). To facilitate or hinder the deposition of DT molecules...

Thermal phase diagrams are computed for binary mixtures of different fatty acids with 1-dodecanol to design new eutectic phase change materials with melting temperatures and latent heatof fusion ranging from 15.5 to 19 °C and 183 to 188 kJ kg−1, respectively. The lauric (LA), myristic (MA) and ...

A polytetrafluoroethylene (PTFE) membrane was used in membrane-assisted extractive (MAE) fermentation of acetone–butanol–ethanol (ABE) by Clostridium saccharoperbutylacetonicum N1-4. The growth inhibition effects of 1-dodecanol, which has a high partition coefficient for butanol, can be preven...

Multiwall carbon nanotubes supported MoO3 (Mo/MWCNTs) and potassium containing Mo/MWCNTs (K/Mo/MWCNTs) catalysts were prepared and characterized with XRD, N2-physisorption, SEM, TEM, NH3-TPD, and TGA/DTA. Increasing the Mo content (5–15 wt%) in Mo/MWCNTs samples diminished BET surface area and ...

Growing interest in finding renewable alternatives to conventional fossil fuels and petroleum-derived specialty chemicals has motivated the investigation of biomass-derived alcohols to make ethers as diesel additives or lubricants. To optimize the direct etherification of long chain alcohols in ...

Vapor–liquid (VLE), liquid–liquid (LLE), and vapor–liquid–liquid equilibria (VLLE) data for the carbon dioxide + 1-dodecanol system at 293.15, 303.15, 313.15, 333.15, and 353.15 K up to 9.36 MPa and phase compositions of the two liquid phases and vapor phase as a function of temperature alon...

Sodium dodecyl sulfate (SDS) exhibits crystallisation upon exposure to low temperatures, which can pose a problem in terms of product stability.
