Bio‐Inspired Damage‐Tolerant Si‐Based Anode for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Silicon is a promising anode material for lithium‐ion batteries due to its high specific capacity, but it suffers from large volume change and rapid brittle fracture during the lithiation/delithiation cycling process. Although the majority of the literature work has tried to avoid fracture by restraining volume expansion or relieving expansion

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Vanadium redox flow batteries show considerable promise for energy storage, yet their overall performance is still hindered by the limited electrochemical activity of graphite felt (GF) electrodes. Herein, using folic acid and metal salts as precursors, M–N–C functionalized carbon nanosheets (M–NC, M=Co, Fe, and Ni) were prepared via a ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Agricultural development initiatives in sub‐Saharan Africa have emphasized improved crop varieties as a pathway to food security, resilience, and rural poverty reduction. However, empirical evidence often focuses narrowly on plot‐level outcomes and overlooks whole‐farm effects and the substantial heterogeneity in farmers' management practices,
