Al together now! A new stable aluminum aminoterephthalate system contains octameric building blocks that are connected by organic linkers to form a 12-connected net (see picture). The structure adopts a cubic centered packing motive in which octameric units replace individual atoms, thus forming distorted octahedral (red sphere) and tetrahedral cages (green spheres) with effective accessible diameters of 1 and 0.45 nm, respectively.

The crystal structure determines the properties of compounds and materials, although one can find simple yet industrially relevant compounds such as potassium acetate (KOAc) and its hydrates for which the properties and even the composition still remain misunderstood, owing to the lack of structural data. In this study, the crystal structures of KOAc polymorphs and hydrates were determined for the first time. The water content in the crystal hydrates was reliably determined revealing two new phases 3KOAc·2HO and KOAc·HO ( = 0.

The limited cycling durability of Zn anode, attributed to the absence of a robust electrolyte-derived solid electrolyte interphase (SEI), remains the bottleneck for the practical deployment of aqueous zinc batteries. Herein, we highlight the role of local supersaturation in governing the fundamental crystallization chemistry of Zn4SO4(OH)6·xH2O (ZSH) and propose a subtle supersaturation-controlled morphology strategy to tailor the interphase chemistry of Zn anode. By judiciously creating local high-supersaturation environment with organic caprolactam to manipulate the precipitation manner of zinc sulfate hydroxide (ZSH), lattice-lattice matched heterogeneous nucleation of ZSH (001) and Zn (002) is realized in aqueous ZnSO4, producing a dense, pseudo-coincidence interface capable of functioning as decent SEI.

Metal-Organic Frameworks (MOFs) attract attention for their intrinsic porosity, large surface area, and functional versatility. To fully utilize their potential in applications requiring precise control at smaller scales, it is essential to overcome challenges associated with their bulk form. This is particularly difficult for 3D MOFs with spin crossover (SCO) behavior, which undergo a reversible transition between high-spin and low-spin states in response to external stimuli.

Functionalized separators are expected to serve as protective barriers to conquer the lithium dendrite penetration in lithium metal batteries. Herein, a novel self-supporting separator material has been successfully synthesized based on the cellulose acetate and Keggin-type polyoxometalate HPMoO·HO (denoted as CA/PMo). The incorporation of PMo facilitates the transformation of the original finger-like structure of the CA separator into a uniform three-dimensional porous grid architecture, which is more effective in inhibiting the growth of lithium dendrites.

Optimizing hydrogen adsorption and enhancing water absorption are essential for the design of effective hydrogen evolution reaction (HER) electrocatalysts. Herein, a well-defined core-shell-structured P-CoNiMoO@CoP-NiP catalyst was synthesized on nickel foam via high-temperature phosphidation of heterostructured precursor CoMoO·xHO/NiMoO·xHO with hydrogen (H) assistance. This catalyst exhibits good HER performance, requiring only 24 mV of overpotential to achieve a current density of 10 mA cm, and long-term stability, maintaining a current density of 100 mA cm for over 100 h.
