Photoreaction of molecular complex composed of ozone and dimethylamine is investigated by matrix-isolation IR and UV–visible spectroscopies. The UV–visible spectrum of the molecular complex isolated in an Ar matrix shows two broad bands in the region between 400 and 700 nm. Upon red-light irra...
Dimethylamine (DMA) possesses an obnoxious odor which has resulted in public concern during the past several decades. A rare bacterial species proficient to degrade DMA, designated IR-26, was isolated from Indian Oil Corporation Limited (IOCL) and identified as Agromyces and Ochrobactrum sp., wh...
Dimethylamine (DMA), which is mostly generated in fine chemical industry, has enormously threatened the public health, therefore should be eliminated from water efficiently. Superior to any other methods to remove DMA, adsorbing it by sorbent could avoid the generation of secondary pollution. Am...
Herein, we report a highly active [email protected] nanocatalyst for the hydrolytic dehydrogenation of dimethylamine-borane under room conditions. The [email protected] nanocatalyst was readily prepared, stabilized and used effectively in the catalytic dehydrogenation reaction of dimethylamine-b...
The effective coagulation aid epichlorohydrin-dimethylamine was synthesized, its co-effect with three ferric iron species in polyferric chloride on humic acid elimination and membrane pollution in coagulation-ultrafiltration hybrid technique were appraised to improve the hybrid water treatment t...
Stimuli responsive luminescent materials have attracted increasing attention for their potential application in many fields. In this work, dimethylamine substituted bisbenzocoumarins amides (DBCE and DBCP) are synthesized and their optical properties are investigated. These molecules show solvat...
Palladium(II) 2,4-pentanedionate, impregnated on alumina nanopowder, was reduced by dimethylamine borane (DMAB) forming Pd(0) nanoparticles (NPs) at room temperature. Pd(0) NPs could be isolated from solution and characterized by ATR-IR, UV–vis, XRD, SEM, TEM, XPS and BET. The results obtained ...
Molecular dynamics simulation was applied to test and evaluate the ability of several models of carbon dioxide on predicting thermodynamics and transport properties. Firstly, we compared the liquid-vapor coexist curves of seven kinds of carbon dioxide models by molecular dynamics simulations. It...
For the first time, we reported the preparation of the oligomer of carbon dioxide. The oligomerization of carbon dioxide was carried out with the aid of the synergetic catalysis of 1,8-diazabicyclo(5, 4, 0)undec-7-ene (DBU) and quaternary salt of water-soluble chitosan (QWSC), which was conducte...
Fischer-Tropsch is one of the commercially available processes for producing clean synthetic fuel from syngas. Industrially, coal/petcoke/biomass to synthetic fuel processes emits a large amount of greenhouse gas carbon dioxide which itself be utilized to enhance fuel production. This work is an...
Carbon dioxide (CO2) is the largest anthropogenic greenhouse gas (GHG) on the planet contributing to the global warming. Currently, there are three capture technologies of trapping CO2 from the flue gas and they are pre-combustion, post-combustion and oxy-fuel combustion. Among these, the post-c...
Recycling CO2 into fuels and chemicals would lessen dependence on fossil fuels and help to mitigate CO2 emissions. Writing in Proceedings of the National Academy of Sciences, U.S.A., Patterson et al. propose that solar methanol islands, man-made oceanic structures that use renewable energy to ha...
Using carbon dioxide as a resource for enhancing the exploitation of fossil energy and geothermal energy, while realizing the geological storage of carbon dioxide, is an important direction in carbon dioxide capture, utilization, and storage studies. A carbon dioxide wellbore flow model is devel...
The conversion of carbon dioxide (CO2) into fuels using solar energy have been studied extensively since it is very attractive in that this can provide a solution to both problems of the increasing carbon dioxide concentration in the atmosphere and the finding new energy sources. Various materia...
The combination of geothermal energy extraction from hot dry rocks and geological storage of carbon dioxide is a technology whose implementation would contribute to reducing the anthropogenic emission of this gas.The possibility of using carbon dioxide as a working fluid absorbing heat from hot ...
Taking maximum flame propagation velocity, maximum explosion pressure, maximum rate of pressure rise and time-average of rising pressure impulse as index, this paper is aimed at evaluating the inerting effects of carbon dioxide on confined hydrogen explosion by varying initial pressure, carbon d...
The flotation of magnesite and dolomite were investigated with the presence of single dodecylamine (DDA) and combined mixtures of DDA and monohydric alcohols, respectively. The adsorption behavior of DDA, butanol, hexanol and octanol on the surface of the two minerals were shown by molecular dyn...
A pendant bubble tensiometer was modified for the dynamic surface tension (ST) measurement of a dodecylamine (DDA) surfactant solution. The dynamic STs of DDA solutions showed a peculiar relaxation: the ST relaxed from the ST of the solvent, reached a minimum, and then increased to ∼72 mN/m. Th...
Dodecylamine was successfully intercalated into the layer space of kaolinite by utilizing the methanol treated kaolinite–dimethyl sulfoxide (DMSO) intercalation complex as an intermediate. The basal spacing of kaolinite, measured by X-ray diffraction (XRD), increased from 0.72 nm to 4.29 nm aft...
Although dodecylamine (DDA) is a conventional collector for the flotation of smithsonite, the interaction mechanism between DDA and smithsonite is still unclear. In this study, time-of-flight secondary ion mass spectrometry (ToF-SIMS) and principal component analysis (PCA) were used to investiga...
