Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

open access: yesCarbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

URBAN COMPETITIVENESS AND URBAN GOVERNANCE IN THE GLOBALIZING WORLD

Asian Geographer, 2004
Abstract This paper discusses the ideas of urban competitiveness and urban governance in the context of urban transformation in the age of globalization. There are independent spheres of competitiveness at firm, sectoral, urban and national levels due to their own characteristics. But competitive cities are backed by competitive firms.
