CO2 capture with polyamine-based protic ionic liquid functionalized mesoporous silica

Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; He, Yi; Shi, Yao

A mesoporous silica supported polyamine-based protic ionic liquid (PIL) sorbent has been prepared by impregnating tetraethylenepentammonium nitrate onto the surface of SBA-15. This innovative hybrid adsorbent exhibits an excellent CO2 adsorption rate in the rate-controlling step of 147?×?10?3 mmol g?1 s?0.5, at least threefold better than other IL-functionalized and amine-modified…

Relation Between Charge Transport and the Number of Interconnected Lamellar Poly(3-Hexylthiophene) Crystals

Wang, Binghua; Chen, Jingbo; Shen, Changyu; Reiter, Günter; Zhang, Bin

We have investigated the lateral charge transport in a multilamellar network of crystalline structures of poly(3-hexylthiophene) (P3HT) embedded in a matrix of small crystallites and amorphous polymers resulting from crystallization at temperatures close to the melting point. Removing the matrix by an appropriate washing process allowed us to observe a…

A unique Microfiltration membrane derived from the poly(ethylene-co-methyl acrylate)/Poly(vinylidene fluoride) (EMA/PVDF) biphasic blends and surface modification for antifouling application

Remanan, Sanjay; Chandra Das, Narayan

A new polymeric blend system is developed from the EMA and PVDF by melt-mixing at various blend compositions. Different techniques characterize the prepared blends, and especially, optical microscopy, XRD, and SAXS analyses study the blend crystallization. A microporous structure is prepared by selective solubilization of PVDF from the EMA/PVDF blends…

Structural evolution of flow-oriented high density polyethylene upon heating: In situ SAXS and WAXD studies

Liao, Tao; Zhao, Xintong; Yang, Xiao; Coates, Phil; Whiteside, Ben; Jiang, Zhiyong; Men, Yongfeng

The structural evolution of micro-injection molded high density polyethylene (HDPE) at the molecular and lamellar levels was investigated as a function of temperature during heating process using wide angle X-ray diffraction (WAXD) and small angle X-ray scattering (SAXS) techniques. The molded sample exhibits a peculiar multilayer structure of skin and…

Precipitation in original Duralumin A-U4G versus modern 2017A alloy

Brunet, Magali; Malard, Benoit; Ratel-Ramond, Nicolas; Deshayes, Christophe; Joulié, Sébastien; Warot-Fonrose, Bénédicte; Sciau, Philippe; Douin, Joël; De Geuser, Frédéric; Deschamps, Alexis

Precipitation in Duralumin, a historic quaternary alloy of the type: Al–Cu–Mg–Si, was never fully studied nor observed by current electron microscopy techniques. This article presents the full characterization and comparison of two alloys: a Duralumin (A-U4G) from the 1950s collected on a vintage aircraft and its modern equivalent: a 2017A…

Effect of Oleic Acid Coating of Iron Oxide Nanoparticles on Properties of Magnetic Polyamide-6 Nanocomposite

Gupta, Ranjeetkumar; Pancholi, Ketan; De Sa, Rulston; Murray, Duncan; Huo, Dehong; Droubi, Ghazi; White, Maggie; Njuguna, James

This work reports the development and testing of a magnetic polymer (Polyamide 6, PA6) nanocomposite capable of melting when exposed to an external magnetic field. Addition of high concentrations of iron oxide nanoparticles (NPs) can induce quick melting but is detrimental to the mechanical properties of the polymer. To reduce…

Adsorption of organic pollutants by amine functionalized mesoporous silica in aqueous solution. Effects of pH, ionic strength and some consequences of APTES stability

Otalvaro, Julian Ortiz; Avena, Marcelo; Brigante, Maximiliano

A mesoporous silica with MCM-41 type pore array was synthesized by hydrothermal method and then was functionalized with known amounts of 3-aminopropyltriethoxysilane (APTES) in order to study the selective adsorption towards several species/pollutants. Antibiotics doxycycline hydrochloride (DC) and norfloxacin (NFX), the dye methyl orange(MO) and the pesticide 2,4-dichlorophenoxyacetic acid…

Synergistic Enhancement of CO2 Adsorption Capacity and Kinetics in Triethylenetetrammonium Nitrate Protic Ionic Liquid Functionalized SBA-15

Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; Li, Younan; Cao, Guanghan; He, Yi; Shi, Yao

A series of triethylenetetrammonium nitrate protic ionic liquid (TNPIL) functionalized, highly ordered mesoporous SBA-15 molecular sieves with different loadings have been synthesized via impregnation. The CO2 capture performance of the hybrid sorbents was evaluated under conditions mimicking a combustion flue gas (15% CO2) over the temperature range of 298–348 K.…
