Summary: In this study, a flame retardant structure (D-AB) with hydrogen bonds and pi-pi stacking effect was successfully synthesized and blended with poly (lactic acid) (PLA) to prepare flame-retardant films. The addition of D-AB significantly improved the viscoelasticity and complex viscosity of PLA due to synergistic effects. Furthermore, the PLA/D-ABs films exhibited excellent flame retardancy and achieved UL-94 VTM-0 rating and a high LOI value of 30.5% with only a 5 wt % addition of D-AB. The flame retardant mechanism of D-AB in PLA was also studied in detail, revealing the release of PO· radicals and non-combustible gas in the gas phase, as well as the formation of a dense and intact carbon layer in the condensed phase.

Summary: This study develops an ultra-stable and ultra-thin hydrogen organic framework nanosheet with exceptional long-term capacity retention in lithium-ion and sodium-ion batteries. Mechanism studies reveal that the impressive performance retention is attributed to large electron delocalization, fast ion diffusion, and physicochemical stability within the nanosheet. The advantageous features pave the way for developing next-generation low-cost and highly stable energy storage batteries.

Summary: This study reports the first example of non-contact, high-contrast sensing of aromatic amines in a hydrogen-bonded organic framework (HOF). Direct observation of the binding interactions of trapped amines is achieved, leading to charge separation-induced emission quenching between host and guests. Non-contact sensing of aniline and diphenylamine is realized with high quenching efficiencies, showing potential for versatile applications. This work provides an inspiring avenue to engineer multifunctional HOFs via co-crystal preparations, thus enriching applications of porous materials with explicit mechanisms.

Summary: In this study, a novel liquid-liquid-solid system is reported to regulate the selectivity of benzyl alcohol electrooxidation. The selectivity of benzaldehyde increases 200-fold from 0.4% to 80.4% compared with the liquid-solid system at a high current density of 136 mA cm(-2), which is the highest one up to date. In the tri-phase system, the benzaldehyde peroxidation is efficiently suppressed, with the conversion of benzaldehyde being decreased from 87.6% to 3.8%. The as-produced benzaldehyde can be in situ extracted to toluene phase and separated from the electrolyte to get purified benzaldehyde. This strategy provides an efficient way to enhance the selectivity of electrocatalytic cascade reactions.

Summary: This study proposes a metal oxide space-confined strategy to optimize the hierarchical structure of porous carbon cathodes, resulting in improved electrochemical performance of zinc-ion hybrid capacitors (ZIHC). By using low-cost aromatic hydrocarbons as precursors, 3D graphene-like porous carbon nanosheets (3DPC) doped with O and S heteroatoms are synthesized. The well-defined hierarchical porosity of 3DPC, coupled with rich O and S heteroatoms, enables effective ion transport and ion capture, leading to desirable capacity, rate capability, and cycling stability in aqueous ZIHC assemblies. Furthermore, the remarkable electrochemical performance of 3DPC is well-preserved in a quasi-solid-state ZIHC device under various harsh bent states, demonstrating its potential application in flexible and wearable energy storage.

Summary: Localized water-in-salt (LWIS) electrolytes are a promising candidate for high-voltage aqueous electrolytes with low viscosity and low salt content. The choice of an effective diluent is crucial for the properties of LWIS electrolytes. By identifying the donor number of solvents as a descriptor of solvent-salt interaction intensity, organic diluents that have minimal impact on the solvation microenvironment and intrinsic properties of the original high-salt electrolyte can be screened. This allows for the construction of a novel low-viscosity electrolyte with a low dosage of LiNO3 salt and well-preserved intrinsic Li+-NO3 (-)-H2O clusters, leading to improved performance in aqueous supercapacitors.
