Localized High‐Concentration Electrolytes With Semi‐Solvated Hexafluoroisopropyl Methyl Ether Diluent for Wide‐Temperature‐Range Lithium Metal Batteries
Abstract Conventional electrolytes in lithium metal batteries (LMBs) suffer from irreversible interfacial degradation at elevated temperatures and sluggish Li⁺ desolvation/transport kinetics under cryogenic conditions. Herein, we present an innovative semi‐solvated hexafluoroisopropyl methyl ether (HFME) diluent in localized high‐concentration electrolytes (LHCEs) that strategically addresses these limitations. Li⁺ hopping networks within the electrolyte can be preserved even at low temperatures due to the coordination of lithiophilic groups in HFME molecules with Li⁺. Simultaneously, lithiophobic group induced spatial confinement effects promote the formation of anion–cation aggregates (AGGs), significantly optimizing Li⁺ desolvation kinetics and boosting the formation of inorganic‐dominated solid electrolyte interphase (SEI) with exceptional thermal stability. Li||LiFePO 4 (LFP) cell with the diluent‐coordinated LHCEs (DCL) can deliver 125.4 mA h g −1 initial capacity at −20 °C with 92.2% retention after 150 cycles. Under elevated temperatures (65 °C), the DCL‐based Li||LFP cell can maintain the capacity retention of 91.3% over 60 cycles. The Li||NCM811 pouch cell (10 cm × 6.5 cm, capacity: 1000 mA h) based on the DCL exhibits outstanding cycling stability, retaining 91.6% of its initial capacity after 75 cycles. This work pioneers a solvent chemistry paradigm through spatially modulated solvation structures, establishing fundamental design principles for electrolyte for wide‐temperature‐range LMBs.

Heritable symbiont producing nonribosomal peptide confers extreme heat sensitivity and antifungal protection on its host
Insects frequently form associations with maternally transmitted symbiotic bacteria. This transmission mode ensures that symbiont-conferred effects, both beneficial and negative, are passed onto offspring. Here, we report an extreme example of symbiont-mediated temperature sensitivity imposed by a vertically transmitted, defensive symbiont. Pea aphids infected with the bacterial endosymbiont, Fukatsuia symbiotica, resist infection by fungal pathogens but produce few or no offspring when moved from cool (15 °C) to mildly warmer temperatures (20 °C). This temperature-dependent reduction in host fitness is associated with increased symbiont abundance, disordered symbiont localization, and high expression of a horizontally acquired nonribosomal peptide synthetase (NRPS) locus. This NRPS operon is syntenic with the locus responsible for the production of Herbicolin A, a known antifungal produced by some plant-associated Erwiniaceae . Activity of chemical extracts from infected aphids is predictive of in vivo protection against entomopathogenic fungi, indicating that an Herbicolin A–like molecule is the likely source of Fukatsuia’s protective effects against fungal pathogens. Injection of the same chemical extracts into naive aphids partially recapitulates developmental defects observed in natural infections at 20 °C, suggesting that increased levels of this compound contribute to disrupted embryonic development. Finally, the purification of the causal agent revealed Fukatsuia produces a compound similar but not identical to Herbicolin A, that exhibits both antifungal and hemolytic activity. These results suggest that F. symbiotica infection imposes a trade-off between antifungal defense and disrupted embryonic development, mediated by a single genetic locus.
A constricted mitochondrial morphology formed during respiration
Abstract Mitochondria assemble in a dynamic tubular network. Their morphology is governed by mitochondrial fusion and fission, which regulate most mitochondrial functions including oxidative phosphorylation. Yet, the link between mitochondrial morphology and respiratgion remains unclear. Here, we uncover a mitochondrial morphology dedicated to respiratory growth of Saccharomyces cerevisiae, which we refer to as “Ringo”. The Ringo morphology is characterized by stable constrictions of mitochondrial tubules. Ringo constrictions are mediated by the yeast dynamin Dnm1 and, unlike mitochondrial fission, occur in the absence of contacts with the endoplasmic reticulum. Our data show that blocking formation of the Ringo morphology correlates with decreased respiration, decreased expression of OXPHOS subunits and perturbed mitochondrial DNA distribution. These results open important perspectives about the link between mitochondrial form and function.
