Summary: In this paper, a novel cathode material, quinone functionalized hexahydroxytriphenylene (HHTP) and diphenylbutadiynebis (boronic acid) (DPB) based porous polymer (QHHTP-DPB), is suggested for magnesium-ion batteries (MIBs). The material exhibits a stable and highly porous structure with strong affinities for magnesium ions.

Summary: Honeycomb-layered oxides with monovalent or divalent, monolayered cationic lattices have diverse crystalline features and are attractive for next-generation energy storage applications. This study investigates the composition and properties of global honeycomb-layered oxides, specifically Ag2M2TeO6 (M=Ni,Mg,etc), which exhibit Ag atom bilayers with sub-valent states within Ag-rich crystalline domains and Ag-deficient domains. The material shows high ionic conductivity and oxygen-hole electrochemistry during silver-ion extraction, and the bilayered structure and sub-valent states are theoretically understood by spontaneous symmetry breaking of SU(2)x U(1) gauge symmetry interactions. These findings suggest that bilayered frameworks have research applications beyond energy storage.

Summary: Based on ab initio structure searches using evolutionary algorithms, we explored the LaF3-LaX3 (X=Cl, Br, I) system and predicted the structures of LaF2X and LaFX2 (X=Br, I) compounds. LaF2Br and LaFI2 were successfully synthesized and LaF2I showed similar structure but different layer stacking. LaF2I exhibits fluoride ion conductivity comparable to that of non-doped LaF3 and has the potential for better ionic conductivity with appropriate doping. This study demonstrates that structure prediction using evolutionary algorithms can accelerate the discovery of mixed-anion compounds, particularly those with an ordered anion arrangement.

Summary: Fluoride-ion conducting solid materials have potential applications in solid electrolytes for sensing devices and next-generation rechargeable batteries. Previous materials have been limited to single-anion compounds, but the introduction of multiple anions can lead to the formation of anion-ordering crystal structures with new fluoride-ion conducting layers. The fluorosulfide La2+xSr1-xF4+xS2 is found to exhibit fluoride-ion conduction due to the presence of sulfide ions increasing the number of interstitial sites for fluoride ions.

Summary: Lanthanide hydride chalcogenides LnHSe and LnHTe crystallize in 2H and 1H structures, respectively. We expanded the LnHCh (Ch = O, Se, and Te) family to include LnHS (Ln = La, Nd, Gd, and Er) and found that larger Ln prefers the 2H structure while smaller Er prefers the 1H structure. The stability of the 2H structure can be attributed to the relatively small electrostatic repulsion between ChLn6 octahedra.

Summary: A highly efficient g-C3N4 photocatalyst (SF-CN) is developed using a one-pot thermal polymerization method in a salt fog environment. SF-CN is an oxygenated ultrathin porous carbon nitride with an intermolecular triazine-heptazine heterostructure, exhibiting improved band gap, specific surface area, and photocurrent response compared to pristine g-C3N4. Theoretical simulations show that SF-CN has better photocatalytic hydrogen evolution capability than pure triazine and heptazine carbon nitrides. SF-CN achieves an excellent visible light PHE rate of 18.13 mmol h(-1) g(-1), 259.00 times higher than pristine g-C3N4.

Summary: The use of a quasi-monolayer Pt shell (Pt-qms) on a Pd core (Pd-c) can achieve cost and activity targets for the electrocatalytic oxygen-reduction reaction (ORR). In situ X-ray absorption spectroscopy was used to monitor the structural evolution of Pd(c)Pt(qms) during ORR, revealing that Pt-qms undergoes restructuring to form Pt clusters and holes while Pd-c remains stable. Protecting the structure of Pd-c is crucial in the development of high-performance Pd(c)Pt(qms) electrocatalysts.

Summary: By exploiting the chiral-induced spin selectivity (CISS) effect, the authors demonstrate enantioselectivity in the assembly of mesoscale helical supramolecules consisting of achiral molecules without the need for chiral catalysis. Unlike chiral molecules, the helical nature in these supramolecules is revealed to be mesoscopically incorporated by dislocation-induced discretized twists. The appearance of spin-polarized current further confirms the relevance of the CISS effect in these discretized helical supramolecules.
