Composition optimization, structural design, and introduction of external magnetic fields into the catalytic process can remarkably improve the oxygen evolution reaction (OER) performance of a catalyst. NiFe2O4@(Ni, Fe)S/P materials with a heterogeneous core–shell structure were prepared by the sulfide/phosphorus method based on spinel-structured NiFe2O4 nanomicrospheres. After the sulfide/phosphorus treatment, not only the intrinsic activity of the material and the active surface area were increased but also the charge transfer resistance was reduced due to the internal electric field. The overpotential of NiFe2O4@(Ni, Fe)P at 10 mA cm–2 (iR correction), Tafel slope, and charge transfer resistance were 261 mV, 42 mV dec–1, and 3.163 Ω, respectively. With an alternating magnetic field, the overpotential of NiFe2O4@(Ni, Fe)P at 10 mA cm–2 (without iR correction) declined by 45.5% from 323 mV (0 mT) to 176 mV (4.320 mT). Such enhancement of performance is primarily accounted for the enrichment of the reactive ion OH– on the electrode surface induced by the inductive electric potential derived from the Faraday induction effect of the AMF. This condition increased the electrode potential and thus the charge transfer rate on the one hand and weakened the diffusion of the active substance from the electrolyte to the electrode surface on the other hand. The OER process was dominantly controlled by the charge transfer process under low current conditions. A fast charge transfer rate boosted the OER performance of the catalyst. At high currents, diffusion exerted a significant effect on the OER process and low OH– diffusion rates would lead to a decrease in the OER performance of the catalyst.

The low electron transfer efficiency compared to precious metals, few active sites and poor stability of transition metal sulfides (TMSs) limit their wide application in electrocatalysis. Optimizing the electronic structure and morphology is an effective means to improve the catalytic performance of TMSs. In this work, we synthesized a heterogeneous core–shell CoFeMo polymetallic sulfide/N-rich carbon skeleton composite catalyst (CFMS/NC) with CoMo-S as the core and CoFeMo-S as the shell by using MOF as precursor and stepwise substitution method. Compared with monomeric sulfides, polymetallic sulfides can exert the synergistic effect between metals, optimize the electronic structure and improve the intrinsic activity of metallic sulfides. Meanwhile, the core–shell structure supported by N-rich carbon skeleton has larger active specific surface area, higher stability and conductivity. The overpotential of CFMS/NC catalyst is only 122 mV at 10 mA cm −2 for hydrogen evolution reaction (HER) and 325 mV at 50 mA cm −2 for oxygen evolution reaction (OER). Besides, CFMS/NC exhibits outstanding performance in overall water splitting, achieving a current density of 100 mA cm −2 at only 1.76 V and maintaining good stability for 30 h. This study proposes a practical method for synthesizing highly efficient electrocatalysts for water splitting.

The poor moisture resistance of Mn4+-activated fluoride red phosphors restricts their practical applications. Herein, this work proposes the embedment of small radius cations (Si4+ or Ge4+) into the inert shell (K2TiF6) constructed on the surface of K2TiF6:Mn4+ particles, which increases the covalence of the surface lattice and thus leads to a significant improvement of the stability of the fluoride. By using multidimensional microstructural characterization techniques, we confirmed the construction of a heterogeneous shell (K2Ti1−xSixF6 and K2Ti1−yGeyF6) and systematically investigated the construction process. Compared to the untreated K2TiF6:Mn4+, the external quantum efficiencies of the K2TiF6:Mn4+@K2Ti1−xSixF6 and K2TiF6:Mn4+@K2Ti1−yGeyF6 heterogeneous core–shell particles improved by 2–3%, and 99% and 88% of the initial luminescence intensity were maintained after boiling in water for 50 min, respectively, which are significantly better than that (25%) of the homogeneous K2TiF6:Mn4+@K2TiF6. The aging of red and white light-emitting diode devices at a high temperature (85 °C) and a high humidity (85%) shows that the heterogeneous core–shell structures have higher stability than their homogeneous counterparts. The surface lattice enhancement strategy proposed in this work is useful as a reference for improving the properties of other under-stable materials.

Heterogeneous nuclear ribonucleoproteins (hnRNPs) are a group of 34–120 kDa nuclear proteins that have recently been reported to participate in virus replication. The hnRNP family contains approximately 20 members, including hnRNP A1, hnRNP A2, hnRNP A2B1, hnRNPC, hnRNPD and hnRNPK. HnRNPC plays important roles in RNA biology, including expression, stability, mRNA splicing, nonspecific sequence export and 3’-end processing; however, the mechanisms underlying hnRNPC regulatory roles are not fully understood. Here, we found that zebrafish hnRNPC promoted spring viraemia of carp virus (SVCV) replication by increasing the stability of SVCV phosphoprotein while inhibiting the K48-linked ubiquitination of virus phosphoprotein, thereby suppressing the type I interferon (IFN) response. Mechanistically, hnRNPC could interact with the mediator of IFN regulatory factor 3 activation (MITA) to activate K48-linked ubiquitination for MITA degradation through the C-terminal domain of hnRNPC. We also showed that human hnRNPC could interact with MITA and that the overexpression of human hnRNPC decreased MITA protein in HEK293 cells, suggesting that the negative regulatory effects of hnRNPC on the type I IFN response are evolutionarily conserved. Collectively, our data indicate that hnRNPC promotes virus replication by suppressing IFN production activated by MITA and increasing the availability of viral proteins. Our work reveals an evolutionarily conserved mechanism that controls the IFN-mediated antiviral response by a member of the hnRNP family in vertebrates.

This work reports the use of compositionally heterogeneous asymmetric [email protected] core–satellite nanoassembly functionalized with DNA sequence as unique signaling nanoprobes for the realization of new energy-transfer-based photoelectrochemical (PEC) immunoassay of prostate- specific antigen (PSA). Specifically, the [email protected] asymmetric core–satellite nanoassemblies ( [email protected] ACS) were fabricated on a two-dimensional glass substrate by a modified controlled assembly technique, and then functionalized with DNA sequences containing PSA aptamers as signaling nanoprobes. Then, the sandwich complexing between the PSA, its antibodies, and the signaling nanoprobes was performed on a CdS QDs modified indium tin oxide (ITO) electrode. The single stranded DNA can server as a facile mediator that place the [email protected] ACS in proximity of CdS QDs, stimulating the interparticle exciton–plasmon interactions between [email protected] ACS and CdS QDs and thus quenching the excitonic states in the latter. Since the damping effect is closely related to the target concentration, a novel energy-transfer-based PEC bioanalysis could be achieved for the sensitive and specific PSA assay. The developed biosensor displayed a linear range from 1.0×10 −11 g mL −1 to 1.0×10 −7 g mL −1 and the detection limit was experimentally found to be of 0.3×10 –13 g mL −1 . This strategy used the [email protected] ACS-DNA signaling nanoprobes and overcame the deficiency of short operating distance of the energy transfer process for feasible PEC immunoassay. More significantly, it provided a way to couple the plasmonic properties of the Ag NPs and Au NPs in a single PEC bioanalytical system. We expected this work could inspire more interests and further investigations on the advanced engineering of the core–satellite or other judiciously designed nanostructures for new PEC bioanalytical uses with novel properties.
