Ion bridging enables high-voltage polyether electrolytes for quasi-solid-state batteries.

Polyether electrolytes have been widely recognized for their favorable compatibility with lithium-metal, yet they are hampered by intrinsically low oxidation thresholds, limiting their potential for realizing high-energy Li-metal batteries. Here, we report a general approach involving the bridge joints between non-lithium metal ions and ethereal oxygen, which significantly enhances the oxidation stability of various polyether electrolyte systems. To demonstrate the feasibility of the ion-bridging strategy, a Zn ion-bridged polyether electrolyte (Zn-IBPE) with an extending electrochemical stability window of over 5 V is prepared, which enables good cyclability in 4.

Revealing the Complex Interaction of Noncoding RNAs, Sirtuin Family, and Mitochondrial Function.

Mitochondria are key organelles that perform and coordinate various metabolic processes in the cell, and their homeostasis is essential for the maintenance of eukaryotic life. To maintain mitochondrial homeostasis and cellular health, close communication between noncoding RNAs (ncRNAs) and proteins is required. For example, there are numerous crosstalk between ncRNAs and the sirtuin (SIRT1-7) family, which is a group of nicotinamide adenine dinucleotides (NAD(+))-dependent Type III deacetylases.

Marek's disease virus-encoded microRNA-M6-5p facilitates viral latent infection by targeting histone demethylase KDM2B.

Marek's disease virus (MDV), a highly contagious and oncogenic avian alphaherpesvirus, establishes a latent infection primarily in CD4 T cells. Latent infections are necessary for both persistent lifelong MDV infection and viral tumorigenesis. MicroRNAs (miRNAs) play critical roles as post-transcriptional regulators of viral infections.

Fluorinated and methylated -benzodipyrrole-based acceptors suppressing charge recombination and minimizing energy loss in organic photovoltaics.

The elimination of the A' unit from -type Y6-derivatives has led to the development of a new class of -benzodipyrrole (-BDP)-based A-DBD-A-type NFAs. In this work, two new A-DBD-A-type NFAs, denoted as CFB and CMB, are designed and synthesized, where electron-withdrawing fluorine atoms and electron-donating methyl groups are substituted on the benzene ring of the -BDP moiety, respectively. CFB exhibits a blue-shifted absorption spectrum, stronger intermolecular interactions, shorter π-π stacking distances, and more ordered 3D intermolecular packing in the neat and blend films, enabling it to effectively suppress charge recombination in the PM6:CFB device showing a higher PCE of 16.
