A blue fluorescent tetraphenylethylene-based dication and a red-NIR phosphorescent rhenium octahedral cluster tetra-anion are associated electrostatically to generate a supramolecular ionic framework which crystallizes in the 1̄ centric space group. The emission properties of the hybrids are studied in the crystalline state and in solution revealing a resonant energy transfer and a high sensitivity toward oxygen.

The dynamics of the different constituents of the ionic liquid 1-hexyl-3-methylimidazolium chloride (HmimCl) is investigated using nuclear magnetic resonance including chlorine relaxometry, line shape analysis, and proton-detected diffusometry, as well as frequency-dependent shear mechanical measurements. This combination of techniques is useful to probe the individual motions of the anions and the cations, and the sample's overall flow response. The 35Cl- dynamics appears to be close to the structural (or α-) relaxation as seen by rheology.

The LiAlTi(PO) (LATP)-polymer composite solid electrolyte offers environmental stability and safety for high-energy lithium metal batteries (LMBs), yet suffers from interfacial instability and high interfacial resistance. Herein, a Janus self-supporting skeleton (J-SSK) is engineered via multi-scale coupling of poly(vinylidene fluoride-trifluorethylene) (PVDF-TrFE), LATP, 2-(3-(6-methyl-4-oxo-1,4-dihydropyrimidin-2-yl) ureido) ethyl methacrylate (UPyMA) monomer, where intermolecular multiple hydrogen bonds reinforce mechanical robustness while the Janus structure isolates LATP from direct Li contact. In situ copolymerizing vinylene carbonate (VC) and UPyMA monomer in J-SSK to construct Janus composite quasi-solid electrolyte (J-CQSE) achieves seamless integration of electrode/electrolyte interfaces and establishes hierarchical coupling across J-SSK, polymer matrix, and lithium salts.

Self-healing polymeric coatings represent a transformative class of smart materials capable of autonomously or stimuli-responsively repairing mechanical or environmental damage, thereby significantly extending the operational lifespan of protected substrates. This review systematically elucidates the underlying mechanisms and chemistries enabling self-healing behavior, encompassing both extrinsic strategies such as microcapsules, microvascular networks, and corrosion inhibitor reservoirs and intrinsic approaches based on dynamic covalent (e.g.

Ruthenium (Ru) has emerged as a highly promising and cost-effective alternative to Ir- and Pt-based electrocatalysts for water electrolysis, making the development of efficient and stable Ru-based bifunctional catalysts a critical research objective. Herein, an AgCl/RuO heterojunction is prepared via a facile electrospinning-calcination strategy. The AgCl undergoes a reduction to form metallic Ag under hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) processes, which can be integrated with RuO active sites to facilitate HO dissociation and enhance the electron transfer while simultaneously suppressing RuO over-oxidation.

Pharmaceutical cocrystals have emerged as a transformative approach in drug development, enhancing the physicochemical properties of active pharmaceutical ingredients (APIs) such as solubility, bioavailability, stability, and dissolution rate without altering their pharmacological characteristics. Defined as multicomponent crystalline solids composed of two or more neutral molecules in a stoichiometric ratio, cocrystals are formed through non-ionic interactions like hydrogen bonding and π-π stacking. This review explores the evolution, design, preparation, and applications of pharmaceutical cocrystals, highlighting their ability to improve drug performance, enable controlled release, and offer intellectual property opportunities.
