A facile, universal surface engineering strategy is proposed to address the volume expansion and slow kinetic issues encountered by SiO/C anodes. A B-/F-enriched buffering interphase is introduced onto SiO/C by thermal treatment of pre-adsorbed lithium salts at 400 °C. The as-prepared anode integrates both high-rate performance and long-term cycling durability.

Objective: Adeno-associated viruses (AAVs) are widely used as gene therapy vectors due to their safety, stability, and long-term expression characteristics. The objective of this work is to develop an aqueous two-phase system (ATPS) as a universal platform for the separation and purification of AAVs.
Results: This study utilized polyethylene glycol (PEG)/salt ATPSs to separate and purify various AAV serotypes, including AAV5, AAV8, and AAV9, which focusing on serotype-specific performance and partial empty capsid removal.

The random distribution of organic-phases (OPs) and inorganic-phases (IOPs) in native solid electrolyte interface (SEI) derived a sluggish Li-ion de-solvation and transmission, impairing the high-rate performance of lithium metal anodes (LMAs). Herein, a multiphases gradient distribution hybrid interface is constructed on metallic Li by surface chemical reconstruction. Theoretical simulations and experiments verify that the Li-ion unloading and infiltrating behaviors are tuned by functional complementary effects, enabling speedy kinetics.

The irreversibility and low utilization of Zn anode stemming from the corrosion and dendrite growth have largely limited the commercialization of aqueous zinc batteries. Here, a carbonyl-rich polymer interphase of zinc polyacrylate (ZPAA) is spontaneously in-situ constructed on Zn anode to address the above-mentioned dilemmas. The ZPAA interlayer enables fast transport kinetics of Zn and tailors the interfacial electric field for realizing the uniform Zn deposition due to superior zincophilicity, high Zn transference number and inherent ion-diffusion channel.

All-solid-state batteries with oxide electrolytes and high-nickel layered oxide cathodes (LiNiCoMnO and LiNiCoAlO, + + = 1, ≥ 60%) have received widespread attention owing to their high energy density and high safety. However, they generally suffer from interfacial structural instability when coupled with solid-state electrolytes, which strongly diminishes the longevity of the battery. In this work, we propose adding a sacrificial additive C to the catholyte buffer layer between LiAlTi(PO) (LATP) and LiNiCoMnO (NCM811) to enhance the electrochemical stability under high-voltage operating conditions.
