Fenton-like reaction has been widely used to decompose organic pollutants via heterogeneous catalysis mechanism. Graphene-based materials have attracted lots of attention in catalysis process, but the catalysis efficiency and stability of these materials are still needed to improve. In this work...

We report the use of triethylenetetramine (TETA) as a dopant of graphene transparent conducting electrodes (TCEs) for Si heterojunction solar cells. The molar concentration (nD) of TETA is varied from 0.05 to 0.3 mM to optimize the graphene TCEs. The TETA-doped graphene/Si Schottky solar cells s...

The triethylenetetramine-functionalized graphene (TFGn) was prepared using graphene oxide (GO) and triethylenetetramine as raw materials through a one-step reaction under alkaline condition. The triethylenetetramine not only acted as cross-linker to combine GO, but also as reductant of GO. The T...

In this article, the dataset on the effect of different triethylenetetramine (TETA: C6H18N4) concentrations on the corrosion-rate of steel-rebar embedment in steel-reinforced concrete immersed in 0.5 M H2SO4 (for simulating industrial/microbial environment) is presented. The corrosion test-data ...

Mesoporous silica particles, based on SBA-15 matrix, were functionalized with triethylenetetramine (TETA), and characterized by transmission electron microscopy (TEM), small angle X-ray scattering (SAXS), and N2-adsorption/desorption isotherms (surface area and pore size distribution). The funct...

A novel triethylenetetramine (TEAE) modified chitosan microbeads with multicavity structure encapsulated in alginate backbone (named as HCTA) was fabricated for Cr(VI) removal from aqueous solution. Cr(VI) removal was investigated in batch and column modes. FTIR, SEM-EDS, XRD and XPS, etc. were ...

Uptake of metals, organics, and formation of metal-organic complexes on the surface or in the interlayer of clay minerals had been studied extensively over the last half century. In this study, we investigated the uptake mechanisms of Cu2+, triethylenetetramine (TETA), and Cu-TETA on rectorite a...

The solid–liquid–gas equilibrium data of the tetra-n-heptyl ammonium bromide ([thepAm][Br])–CO2 system, and then the solubility and absorption kinetic data of CO2 in different phases of [thepAm][Br] were measured by a high pressure quartz spring method. Results showed high molar fractions of ...

This research focused on two classes of synthetic and naturally derived toxins with the specific goal of identifying materials that elicit rapid neurological impacts. The insecticidal chemistries studied here included five heterobicyclic compounds and eight formate esters. We also tested four pr...

Solubilization of cholesterol, differential scanning calorimetric (DSC), nuclear magnetic resonance (NMR) and dynamic light scattering (DLS) measurements were performed in order to reveal the dispersion mechanisms of stratum corneum (SC) into each intact corneocytes in the following systems: (1)...

The dispersion of stratum corneum (SC) into intact cells has been studied in aqueous mixed micelle solutions containing α-Terpineol (α-T) solubilized in solutions of N,N-dimethyldodecylamine oxide (C12,DMAO). The dispersion was found to be most effective when α-T is solubilized in the saturat...

The dispersion of stratum corneum (SC) into each intact cell was studied in aqueous micellar solutions of N,N-dimethyldodecylamine oxide (C12DMAO) solubilizing limonene and was found to be the most effective, especially when the saturated amount of limonene was solubilized in the micellar soluti...

Emulsions have been widely applied in subterranean enhanced oil recovery processes, cosmetics and chemistry engineering fields, etc. Current research interests are focusing on improving the stability of emulsion by involving surfactants or colloidal materials. This work aims to enhance the emuls...

Density functional theory (B3LYP) calculations of the hydration of trimethylamine-N-oxide (TMAO) and a surfactant dimethyldodecylamine-N-oxide (DDAO) are reported. Hydrogen-bonded complexes of DDAO with up to three water molecules and of TMAO with up to five water molecules are studied. Interact...

The surface excess of dimethyldodecylamine-N-oxide (DDAO) surfactant at the mica–water interface has been determined using phase modulated ellipsometry. Surface excess versus bulk surfactant concentration isotherms were constructed at different pH values. The plateau adsorbed amount reaches a m...

Zn-SiO2 composite electrodeposits have been produced from a sulphate bath. The effects of process parameters such as current density, agitation, particle loading and deposition time on the rate of particle incorporation are presented. It was shown that the amount of SiO2 embedded in the coating ...

Surfactant crystallisation is important in many applications in the food, consumer product and medical sectors. However, these processes are not well understood. In particular, surfactant crystallisation can be detrimental to the stability of detergent formulations, such as dish liquid products,...

HypothesisAt low temperatures stability issues arise in commercial detergent products when surfactant crystallisation occurs, a process which is not currently well-understood. An understanding of the phase transition can be obtained using a simple binary SDS (sodium dodecyl sulfate) + DDAO (N,N-...

A new N,N-dimethyldodecylamine functionalized magnetic adsorbent (Fe3O4@MDHM) was fabricated and used for the efficient enrichment of flavonoids under the format of magnetic solid phase extraction (MSPE). Different techniques were utilized to characterize the spectroscopic, morphology and magnet...

The synthesis of decyl acetate, by the transesterification of vinyl acetate with decanol, was studied using supercritical CO2 as solvent and immobilized Candida antarctica lipase B as catalyst (Novozym® 435). The enzymatic content was determined for each particle size of the catalyst, indicating...
