Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 828-839, May 2026.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Wealth inequality and epidemics in the Republic of Venice (1400–1800)

open access: yesThe Economic History Review, Volume 79, Issue 2, Page 811-849, May 2026.
Abstract This article analyses wealth inequality in the Republic of Venice during 1400–1800. The availability of a large database of homogeneous inequality measurements allows us to produce the most in‐depth study of the factors affecting inequality at the local level available thus far for any preindustrial society.

Cooperative human signals to honeyguides form local dialects

open access: yesPeople and Nature, Volume 8, Issue 3, Page 682-694, March 2026.
Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

Climate Shapes the Ratio Between Aboveground Plant Biovolume and Topsoil Macronutrients Worldwide

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Soil nutrients are a major limiting factor for plant biomass, yet paradoxically, some of the most productive ecosystems thrive in nutrient‐poor soils. Here, we conducted a global field survey in 421 sites across all major biomes to investigate the environmental factors controlling the ratio between plant biovolume (a proxy for aboveground ...
