The anhydrous proton conductivity of Im@IEF-11 resulting from the integration of imidazole and porous IEF-11 has been investigated, and the highest proton conductive value can reach up to 7.64 × 10−2 S cm−1. Furthermore, IEF-11 is also developed to reduce CO2 due to its reasonable structure and suitable energy band, and its CO formation rate is 31.86 μmol g−1 h−1. [ABSTRACT FROM AUTHOR]

Background. In recent years, a growing body of research has revealed that long noncoding RNAs (lncRNAs) participate in regulating genomic instability. Materials and Methods. We obtained RNA expression profiles, somatic mutation profiles, clinical information, and pathological features of colorectal cancer (CRC) from The Cancer Genome Atlas project. We divided the cohort into two groups based on mutation frequency and identified genomic instability-related lncRNAs (GI-lncRNAs) using R software. We further analyzed the function of identified GI-lncRNAs and established a prognostic model through Cox regression. Using the established prognostic model, we divided the cohort into the high- and low-risk groups and further verified the prognostic differences between the two groups as well as the predictive power of prognosis-related lncRNAs in the genomic instability of CRC. Results. We identified a total of 143 GI-lncRNAs that were differentially expressed between the higher mutation frequency group and the lower mutation frequency group. According to Kyoto Encyclopedia of Genes and Genomes pathway and Gene Ontology analyses, a series of cancer-associated terms were enriched. We further constructed a prognostic model that included five GI-lncRNAs (lncRNA PTPRD-AS1, lncRNA AC009237.14, lncRNA LINC00543, lncRNA AP003555.1, and lncRNA AL109615.3). We confirmed that the expression of the five GI-lncRNAs was associated with prognosis and the mutation of critical genes in the CRC patient cohort. Conclusions. The present research further confirmed the vital function of GI-lncRNAs in the genomic instability of CRC. The five GI-lncRNAs identified in our study are potential biomarkers and need to be studied in more depth. [ABSTRACT FROM AUTHOR]

Metal–organic frameworks (MOFs) provide an ideal platform for loading various guests owing to their available space, and can be developed as a class of multifunctional materials. Herein, we cover the design and synthesis of two kinds of exchanged frameworks with multifunctional applications based on H3ImDC and In(NO3)3·2H2O through guest exchange inside the framework. The guest ammonium ion (NH4+) and [Ru(2,2′-bipyridine)3]2+ (Rubpy) are selected to exchange the dimethylammonium cation (Me2NH2+) encapsulated within In-MOF, giving birth to two kinds of new MOFs, named NH4+@In-MOF and Rubpy@In-MOF respectively. The proton conduction of NH4+@In-MOF and the CO2 photoreduction of Rubpy@In-MOF are investigated. Under different test conditions, the proton conductive behaviors of NH4+@In-MOF are evaluated and the best proton conductive value can reach up to 9.81 × 10−3 S cm−1. Compared to the original In-MOF, Rubpy@In-MOF exhibits a significantly enhanced CO2 photoreduction performance under a pure CO2 atmosphere. Furthermore, its photocatalytic activity is retained even under a 10% CO2 gas atmosphere, displaying a synergistic effect between Rubpy and In-MOF24 within Rubpy@In-MOF. [ABSTRACT FROM AUTHOR]

Hybrid materials PPy/Ni–Co LDH based on polypyrrole nanotubes and Ni–Co LDH from ZIF-67 templates were employed as electrode materials for supercapacitors, where Ni–Co LDH possesses a hollow structure. With the help of appreciative composition and a hollow structure, the optimum PPy/Ni–Co LDH shows an excellent performance with high specific capacitances (4.4 C cm−2 at 1 mA cm−2 and 3.35 C cm−2 at 20 mA cm−2).

KVPC exhibit high proton conductive behaviours due to particles with different sizes. This is the first metal organic-phosphate framework in which proton conductivity has been tuned by different particle sizes. • KVPC exhibit different conductive behaviors due to particles with different sizes. • The conductivity of KVPC-S is high to 1.15 × 10−2 S cm−1 at 40 °C under 95% RH. • The conductivity of membranes reach up to 1.19 × 10-3 S cm−1 and remain no significant change within 6 h. The proton conductions of open-framework metal phosphates K 2 [(VO) 2 (HPO 4) 2 (C 2 O 4)] (KVPC) with large and small particle sizes, namely KVPC-L and KVPC-S, have been evaluated. Varied particle sizes result in different proton conductive behaviors. KVPC-S exhibits a high proton conductivity of 1.15 × 10−2 S cm−1 under 40 °C, 95% RH and possesses a stable proton conduction for 4 h. Furthermore, proton conductivities of composite membranes are investigated, and the value can reach up to 1.19 × 10-3 S cm−1 under 60 °C, 95% RH and remain no significant change within 6 h.

Reasonable construction of electrodes materials with heterostructures is a very effective way to enhance the electrochemical performance. Herein, a series of hybrid electrodes materials (PPy/Ni–Co LDH) based on nickel-cobalt layered double hydroxide (Ni–Co LDH) with zeolitic imidazolate framework-67 (ZIF-67) as the template and polypyrrole (PPy) nanotubes have been synthesized. Various precursors PPy/ZIF-67 based on polypyrrole nanotubes with the same amount have been prepared, where the mass ratio of polypyrrole nanotubes to ZIF-67 are varied in the process of crystallization. As-synthesized precursors PPy/ZIF-67 serve as sacrificial templates and give birth to various hybrid electrodes materials PPy/Ni–Co LDH with the core-shell structure, where Ni–Co LDH is closely coated on the external surface of polypyrrole nanotubes. The experimental findings reveal the electrochemical performance of PPy/Ni–Co LDH becomes better and better with increasing masses of Ni–Co LDH. Benefiting from their core-shell structure and the synergy effect between polypyrrole nanotubes and Ni–Co LDH, the optimized sample displays a specific capacitance of 13.0 F cm−2 (1858.3 F g−1) at 1 mA cm−2 and a favorable rate capability. Furthermore, a symmetric coin-type hybrid supercapacitor based on the optimized sample has also been fabricated, and exhibits an energy density of 10.425 mWh·cm−2 at the power density of 0.25 mW cm−2. Hybrids PPy/Ni-Co LDH are used for supercapacitors and show high specific capacitances via synergistic effect between Ni-Co LDH and PPy. Image 1 • Polypyrrole inter-connected hollow Ni/Co LDH hybrids are prepared. • Their performance are better and better with increasing Ni–Co LDH masses. • The optimum sample displays a capacity of 13 F/cm2 and a favorable rate capability. • Their performance can attribute to the synergy effect between PPy and Ni–Co LDH.

With the increasing demand for preparing energy storage devices, composites containing metal oxides, have been widely developed and used as supercapacitors. However, the electrochemical performances of such materials are unable to be satisfied owing to the inherent poor conductivity. Herein, we employ "in-situ pyrolysis" approach to fabricate composite electrode materials without binding agents, which are obtained by the direct calcination of the mixture MnO 2 and poly (vinylidene difluoride) coated on carbon cloths, generating a family of binder-free electrode materials BE-X. For comparison, another family of electrode materials CE-X have been obtained through the conventional method. Naturally, two different families of electrode materials are prepared and exhibit different electrochemical performances. In general, the performances of electrode materials prepared by an "in-situ pyrolysis" approach are better than those of electrode materials via the conventional method, indicating the enhanced adhesion between electrode materials and current collectors could be benefit for the electrochemical process. Among all prepared electrode materials, BE-7 exhibits the best performance (5.44 F cm−2 at 5 mV s−1) as well as a good rate stability. Furthermore, a flexible symmetric supercapacitor device based on BE-7 is also prepared, and exhibits an areal capacitance of 100.50 mF cm−2. Two family of electrodes prepared by different methods exhibit varied performances, where the performances of binder-free electrodes prepared by the in-situ pyrolysis approach are better than those of electrodes by the conventional methods. Image 1 • An efficient binder-free electrode has been prepared simply through "in-situ pyrolysis" approach. • The electrodes prepared by different methods result in different performances. • The performance of binder-free electrodes are better than those of electrodes prepared by conventional electrodes. • A flexible symmetric supercapacitor device exhibits an areal capacitance of 100.5 mF cm−2.
