Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

River-groundwater transformation and ecological effects in the Tuwei River watershed [PDF]
The Tuwei River, an important tributary of the Yellow River, located in the eastern Jiziwan region exhibits a close hydraulic connection between atmospheric precipitation, groundwater, and river-lake water in the watershed. This connection influences the

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
