When Illness Becomes Debt: Catastrophic Health Expenditures and Financial Distress—Evidence From India's Healthcare System

open access: yesWorld Medical &Health Policy, Volume 18, Issue 3, September 2026.
ABSTRACT This study examines the association between catastrophic health expenditure (CHE) and distress financing among India's uninsured “missing middle,” a population largely excluded from public insurance schemes and private coverage. While healthcare‐induced financial hardship is well documented, evidence on subsequent coping strategies among this ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2889-2905, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...
