    Abstract For the application of proton exchange membrane fuel cells (PEMFCs) in a wide temperature range, an ionogel incorporated into poly(2,5-benzimidazole) (ABPBI) membranes with low phosphoric acid doping levels was designed. The natural sepiolite was first acid-treated to obtain one-dimensional silicon nanorods (SNRs) with a large specific surface area and a hierarchical porous structure. The SNRs were then filled with imidazolium ionic liquid (IL) to prepare IL@SNR ionogels. Analysis of related spectra and thermal behavior verified that the IL molecules were confined in the inner channels of SNRs. The as-prepared IL@SNRs were embedded in the ABPBI to form composite membranes (ABPBI/IL@SNRs) via in situ synthesis. By immobilizing proton conductors, the ABPBI/IL@SNR composite membranes markedly improved proton conductivity with low phosphoric acid doping levels in a wide temperature range. A single-cell based on 5 wt% IL@SNRs embedded in a composite membrane achieved a maximum power density of 0.15 and 0.28 W cm−2 at 80 °C and 180 °C, respectively, with 0% RH. The proton conductivities were comparable to those of Nafion-based PEMFCs under the same temperature and humidity conditions and competed with those of reported polybenzimidazole–inorganic composite membrane-based PEMFCs at high temperatures. By using a facile method to prepare nanostructured fillers, the strategy of avoiding proton carrier wastage can be potentially used in the production of high-performance membranes for PEMFCs.

    Abstract Background: Pennisetum giganteum, an abundant, fast-growing perennial C
    Results: To elucidate the cold stress responses of P. giganteum, we carried out comprehensive full-length transcriptomes from leaf and root tissues under room temperature (RT) and chilling temperature (CT) using PacBio Iso-Seq long reads. We identified 196,124 and 140,766 full-length consensus transcripts in the RT and CT samples, respectively. We then systematically performed functional annotation, transcription factor identification, long non-coding RNAs (lncRNAs) prediction, and simple sequence repeat (SSR) analysis of those full-length transcriptomes. Isoform analysis revealed that alternative splicing events may be induced by cold stress in P. giganteum, and transcript variants may be involved in C18 unsaturated fatty acid biosynthesis and metabolism pathways at chilling temperature in P. giganteum. Furthermore, the fatty acid composition determination and gene expression level analysis supported that C18 unsaturated fatty acid biosynthesis and metabolism pathways may play roles during cold stress in P. giganteum.
    Conclusions: We provide the first comprehensive full-length transcriptomic resource for the abundant and fast-growing perennial grass Pennisetum giganteum. Our results provide a useful transcriptomic resource for exploring the biological pathways involved in the cold stress responses of P. giganteum.
