Aqueous Zn-ion BatteriesIndium surface-modified Zn powders are utilized in a pilot-scale solvent-free electrode process (SFE@In), resulting in the formation of a 3D Zn deposition network with uniformly distributed electric field. This approach enables the fabrication of soft-packaged batteries that eliminates dendrite short-circuiting and hydrogen evolution. The battery exhibits remarkable stability, maintaining over 200 cycles at the assembled 2.4 Ah level. More in article number2308541, Haitao Zhou and co-workers. (Source: Small)

Interfacial Triboelectricity Lights Up Phosphor ‐Polymer Elastic Composites: Unraveling the Mechanism of Mechanoluminescence in Zinc Sulfide Microparticle‐Embedded Polydimethylsiloxane Films (Small 17/2024)
MechanoluminescenceThe cover image illustrates that self-recoverable mechanoluminescence (ML) in ZnS:Cu microparticles embedded in PDMS is originated from electroluminescence of ZnS:Cu achieved through triboelectricity between alumina-coated particle surfaces and PDMS. This enables repeatable ML generation with a gentle touch, press, or stretch, without requiring substantial particle pressure or pre-irradiation with UV/blue light, significantly expanding ML applications by softness and repeatability.

Reduction ‐Induced Uptake of Cs+ in Metal–Organic Frameworks Loaded with Polyoxometalates (Small 17/2024)
Metal –Organic FrameworksThe hybridization of metal –organic frameworks (MOFs) with polyoxometalates (POMs) offered increased Cs+ capture properties in comparison to pristine MOFs. The Cs+ uptake capacity was significantly elevated through the reduction and subsequent increase in the overall negative charge of the POMs. In article number2307004, Naoki Ogiwara, Sayaka Uchida, and co-workers establish the correlation between composition, structure, and Cs+ uptake properties for POM/MOF composites.

Magnesium Ions Promote the Induction of Immunosuppressive Bone Microenvironment and Bone Repair through HIF ‐1α‐TGF‐β Axis in Dendritic Cells
Mg2+ promotes bone regeneration by inducing imDC suppression of effector T cell-mediated adaptive immune inflammation. Specifically, Mg2+ activates the MAPK signaling pathway through the TRPM7 channel on the DC surface, which in turn activates the HIF-1 α-TGF-β axis to inhibit effector T cell activation. Induction of key target HIF-1α expression by roxadustat significantly promotes regeneration in bone-deficient mice. AbstractThe effect of immunoinflammation on bone repair during the recovery process of bone defects needs to be further explored. It is reported that Mg2+ can promote bone repair with immunoregulatory effe...

Continuous Flow Electrochemical Synthesis of Olivine ‐Structured NaFePO4 Cathode Material for Sodium‐Ion Batteries from Recycle LiFePO4
Schematic of the working principle of a continuous flow electrochemical solid-liquid coupled reactor for the synthesis of NFP, by which NFP is successfully synthesized at 50% of the theoretical reductant dosage. The binding energy of NaxFePO4 (0< x< 0.95) is calculated to investigate the incomplete insertion of sodium ions during NFP synthesis. AbstractTo mitigate the environmental impact of the improper disposal of spent LiFePO4 batteries and reduce resource waste, the development of LiFePO4 recycling technologies is of paramount importance. Meanwhile, olivine-structured NaFePO4 in sodium-ion batteries has received ...

Aggregation Inducing Reversible Conformational Isomerization of Surface Staple in Au18SR14 Nanoclusters
Adding alcohol or lowering the pH of the aqueous solution causes the aggregation of Au18SR14, which promotes the reversible change in the folding mode of the unique Au4SR5 staple. This conformational isomerization results in a shift in the solution color between green and orange-red, as well as a transformation in the single and dual emissions. AbstractThe conformation of molecules and materials is crucial in determining their properties and applications. Here, this work explores the reversible transformation between two distinct conformational isomers in metal nanoclusters. This work demonstrates the successful manipulati...
