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.…

The mechanical properties and the hierarchical filler structures were characterized on a series silica-filled silicone rubber with a filler fraction (?Si) varied from 0.05?phr to 80?phr (parts per hundred rubber). Uniaxial elongation measurement suggests that there is a percolation threshold between 10 and 30?phr. Moreover, an optimum ?Si range from…

The electronegative low-density lipoprotein, LDL (?), is an endogenously modified LDL subfraction with cytotoxic and proinflammatory actions on endothelial cells, monocytes, and macrophages contributing to the progression of atherosclerosis. In this study, epitopes of LDL (?) were mapped using a phage display library of peptides and monoclonal antibodies reactive to…

High-Performance Lignin-Containing Polyurethane Elastomers with Dynamic Covalent Polymer Networks

Liu, Weifeng; Fang, Chang; Wang, Shengyu; Huang, Jinhao; Qiu, Xueqing

High-performance lignin-containing polyurethane elastomers (LPUes) were successfully synthesized via partially substituting petroleum-derived polyols with depolymerized enzymatic hydrolysis lignin (DEL). The influences of DEL on the structure, thermostability, mechanical performance, and thermal reprocessability of LPUes were systematically studied. The tensile strength and toughness of PUes were…

Ion Transport in Pendant and Backbone Polymerized Ionic Liquids

Kuray, Preeya; Noda, Takeru; Matsumoto, Atsushi; Iacob, Ciprian; Inoue, Tadashi; Hickner, Michael A.; Runt, James

Polymerized ionic liquids (PILs) are single-ion conductors in which one of the ionic species is tethered to the polymer chain while the other is free to be transported. The ionic species can either be directly incorporated into the polymeric backbone (backbone PILs) or placed as pendant groups to the chain…

A kind of side-chain type anion exchange membranes (AEMs) with high ionic conductivity and good comprehensive stability was prepared via direct modification of commercial engineering plastic polyketone with diamines through Paal-Knorr reaction and quaternization reaction. It was found that the amount of diamine can effectively tune the microphase morphology and…

Due to their distinctive molecular architecture, ABA triblock copolymers will undergo specific self-assembly processes into various nanostructures upon introduction into a B-block selective solvent. Although much of the focus in ABA triblock copolymer self-assembly has been on equilibrium nanostructures, little attention has been paid to the guiding principles of nanostructure…

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…

The operational stability of organic solar cells (OSCs) is the essential barrier to commercialization. Compared to thermally-induced degradation, photo-stability of OSCs is far away from being resolved. Here, we demonstrate that the thermal- and photo-degradation of metastable bulk-heterojunction OSCs are governed by the same mechanism. Understanding the fundamental principles behind…
