Recycling Ni‐Rich NCM Cathode Materials From Spent Li‐Ion Batteries as Efficient Electrocatalyst for Urea Oxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mounting battery waste demands sustainable solutions. We recycle spent NCM cathodes into high‐performance urea oxidation catalysts, enabling sustainable hydrogen production and simultaneous urea waste treatment. The burgeoning electric vehicle industry has intensified the demand for high‐energy Ni‐Co‐Mn (NCM) cathodes, yet their end‐of‐life management ...

Functional Urban Areas in Colombia

OECD Regional Development Working Papers, 2016
This paper applies the OECD-EU methodology to identify the functional urban areas (FUAs) in Colombia. Using the municipal boundaries, population grid data and inter-municipalities commuting flows from the 2005 population census, the paper identifies 53 FUAs accounting for 27 million people, or 63% of the national population. The resulting FUAs are then

The Urban Hierarchy and Urban Area Production Function: A Synthesis

Urban Studies, 1977
Urban production functions, often used to indicate optimal city size, usually deal with one city in isolation. This paper introduces differing production and transport costs and demand intensities in order to generate an urban hierarchy of differing urban sizes and market areas.
