Enhanced activity of bimetallic Fe-Cu catalysts supported on ceria toward water gas shift reaction: synergistic

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 1962-1972 doi: 10.1007/s11705-023-2359-z

Abstract: Within the “hydrogen chain”, the high-temperature water gas shift reaction represents a key step to improve the H2 yield and adjust the H2/COx ratio to fit the constraints of downstream processes. Despite the commercial application of the high-temperature water gas shift, novel catalysts characterized by higher intrinsic activity (especially at low temperatures), good thermal stability, and no chromium content are needed. In this work, we propose bimetallic iron-copper catalysts supported on ceria, characterized by low active phase content (iron oxide + copper oxide < 5 wt %). Fresh and used samples were characterized by inductively coupled plasma mass spectrometry, X-ray diffraction, nitrogen physisorption, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, and temperature programmed reduction in hydrogen to relate physicochemical features and catalytic activity. The sample with iron/copper ≈ 1 and 4 wt % active phase content showed the best catalytic properties in terms of turnover frequency, no methane formation, and stability. Its unique properties were due to both strong iron-copper interaction and strong metal-support interaction, leading to outstanding redox behavior.

Structural engineering of transition metal-based nanostructured electrocatalysts for efficient water splitting

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4,   Pages 838-854 doi: 10.1007/s11705-018-1746-3

Abstract: Water splitting is a highly promising approach for the generation of sustainable, clean hydrogen energy. Tremendous efforts have been devoted to exploring highly efficient and abundant metal oxide electrocatalysts for oxygen evolution and hydrogen evolution reactions to lower the energy consumption in water splitting. In this review, we summarize the recent advances on the development of metal oxide electrocatalysts with special emphasis on the structural engineering of nanostructures from particle size, composition, crystalline facet, hybrid structure as well as the conductive supports. The special strategies relay on the transformation from the metal organic framework and ion exchange reactions for the preparation of novel metal oxide nanostructures with boosting the catalytic activities are also discussed. The fascinating methods would pave the way for rational design of advanced electrocatalysts for efficient water splitting.

Exceptionally flame-retardant flexible polyurethane foam composites: synergistic effect of the silicone

Qian Wu, Jincheng Zhang, Shengpeng Wang, Bajin Chen, Yijun Feng, Yongbing Pei, Yue Yan, Longcheng Tang, Huayu Qiu, Lianbin Wu

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 4,   Pages 969-983 doi: 10.1007/s11705-020-1988-8

Abstract: A facile strategy was developed to fabricate flexible polyurethane (PU) foam composites with exceptional flame retardancy. The approach involves the incorporation of graphene oxide (GO) into a silicone resin (SiR) solution, which is then deposited onto a PU foam surface via the dip-coating technique and cured. Fourier-transform infrared spectroscopy, scanning electron microscopy, and Raman spectroscopy measurements demonstrated that the SiR and GO were successfully coated onto the PU skeleton and the intrinsic porous structure of the PU foam remained intact. The effects of SiR and GO on the mechanical and thermal stability and flame retardancy of PU composites were evaluated through compression tests, thermogravimetric analysis, vertical combustion tests, and the limiting oxygen index. The measurement results revealed that the composites (PU@SiR-GO) showed superior flame retardancy and thermal and mechanical stability compared to pristine PU or PU coated with SiR alone. The mechanical and thermal stability and the flame-retardant properties of the PU composites were enhanced significantly with increasing GO content. Based on the composition, microstructure, and surface morphology of PU@SiR-GO composites before and after combustion tests, a possible flame-retardance mechanism is proposed. This work provides a simple and effective strategy for fabricating flame-retardant composites with improved mechanical performance.

MicroRNA-142-3p and microRNA-142-5p are downregulated in hepatocellular carcinoma and exhibit synergistic

Felice Ho-Ching Tsang,Sandy Leung-Kuen Au,Lai Wei,Dorothy Ngo-Yin Fan,Joyce Man-Fong Lee,Carmen Chak-Lui Wong,Irene Oi-Lin Ng,Chun-Ming Wong

Frontiers of Medicine 2015, Volume 9, Issue 3,   Pages 331-343 doi: 10.1007/s11684-015-0409-8

Abstract:

MicroRNAs (miRNAs), an important class of small non-coding RNAs, regulate gene expression at the post-transcriptional level. miRNAs are involved in a wide range of biological processes and implicated in different diseases, including cancers. In this study, miRNA profiling and qRT-PCR validation revealed that miR-142-3p and miR-142-5p were significantly downregulated in hepatocellular carcinoma (HCC) and their expression levels decreased as the disease progressed. The ectopic expression of miR-142 significantly reduced HCC cell migration and invasion. Overexpression of either miR-142-3p or miR-142-5p suppressed HCC cell migration, and overexpression of both synergistically inhibited cell migration, which indicated that miR-142-3p and miR-142-5p may cooperatively regulate cell movement. miR-142-3p and miR-142-5p, which are mature miRNAs derived from the 3′- and 5′-strands of the precursor miR-142, target distinct pools of genes because of their different seed sequences. Pathway enrichment analysis showed a strong association of the putative gene targets of miR-142-3p and miR-142-5p with several cell motility-associated pathways, including those regulating actin cytoskeleton, adherens junctions, and focal adhesion. Importantly, a number of the putative gene targets were also significantly upregulated in human HCC cells. Moreover, overexpression of miR-142 significantly abrogated stress fiber formation in HCC cells and led to cell shrinkage. This study shows that mature miR-142 pairs collaboratively regulate different components of distinct signaling cascades and therefore affects the motility of HCC cells.
