Facilitated Transport Membranes With Ionic Liquids for CO Separations.

In recent years, significant development milestones have been reached in the areas of facilitated transport membranes and ionic liquids for CO separations, making the combination of these materials an incredibly promising technology platform for gas treatment processes, such as post-combustion and direct CO capture from air in buildings, submarines, and spacecraft. The developments in facilitated transport membranes involve consistently surpassing the Robeson upper bound for dense polymer membranes, demonstrating a high CO flux across the membrane while maintaining very high selectivity. This mini review focuses on the recent developments of facilitated transport membranes, in particular discussing the challenges and opportunities associated with the incorporation of ionic liquids as fixed and mobile carriers for separations of CO at low partial pressures (<1 atm).

Capsules of Reactive Ionic Liquids for Selective Capture of Carbon Dioxide at Low Concentrations.

The task-specific ionic liquid (IL), 1-ethyl-3-methylimidazolium 2-cyanopyrolide ([EMIM][2-CNpyr]), was encapsulated with polyurea (PU) and graphene oxide (GO) sheets via a one-pot Pickering emulsion, and these capsules were used to scrub CO (0-5000 ppm) from moist air. Up to 60 wt % of IL was achieved in the synthesized capsules, and we demonstrated comparable gravimetric CO capacities to zeolites and enhanced absorption rates compared to those of bulk IL due to the increased gas/liquid surface-to-volume area. The reactive IL capsules show recyclability upon mild temperature increase compared to zeolites that are the conventional absorber materials for CO scrubbing.

Mixed-matrix membranes incorporated with porous shape-persistent organic cages for gas separation.

There has been much recent interest in the use of porous materials derived from self-assembling, shape-persistent organic cages due to their solubility and easy post-synthetic modification. Herein we report the preparation of novel mixed-matrix membranes (MMMs) employing the porous organic cage Noria and its derivatives Noria-Boc and Noria-COBu as the fillers, and a fluorine containing polyimide, 6FDA-DAM, as the polymeric matrix. The physical structures and properties of Noria and its derivatives were measured and investigated.

Aberrant expression of the autocrine motility factor receptor correlates with poor prognosis and promotes metastasis in gastric carcinoma.

AMFR, autocrine motility factor receptor, also called gp78, is a cell surface cytokine receptor which has a dual role as an E3 ubiquitin ligase in endoplasmic reticulum-associated degradation. AMFR expression is associated with tumor malignancy. We here investigated the clinical significance of AMFR and its role in metastasis and prognosis in gastric cancer.

Expression and role of grainyhead-like 2 in gastric cancer.

The aim of this study was to evaluate the expression and role of Grhl2 in gastric cancer. Immunohistochemistry was performed to explore the expression of Grhl2 in gastric cancer and surrounding non-tumor tissues. Moreover, the mRNA and protein expression level of Grhl2 in human immortalized gastric epithelial cell line GES-1 and four gastric cancer cell lines (MGC803, SGC7901, MKN45, HGC27) were detected by qRT-PCR and Western blotting, respectively.
