Using childhood landscape memories to uncover the dynamics of Anthropocene in African Urbanscapes

People and Nature, EarlyView.
Abstract This perspective provides a reflective account of our personal experiences as African professors and lecturers in diverse fields of environmental sciences encountering the urban Anthropocene. Here, we explain the nature of the unprecedented, potent and hidden changes in our lived environments.

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

Propellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
