Understanding the Factors Influencing the Properties of Biomass‐Derived Porous Carbon and Their Impacts on Electrical Double‐Layer Capacitor Electrodes: A Comprehensive Review

Journal of Renewable Energy, Volume 2024, Issue 1, 2024.
The use of biomass as carbon precursors has been extensively investigated, with a particular emphasis on examining the properties of derived porous carbon and its application in electrical double‐layer capacitors (EDLCs). Biomass‐derived porous carbon‐based electrodes have shown promising properties that can improve the efficiency of EDLCs.

CHARACTERIZATION OF PERIWINKLE SHELL ASH REINFORCED POLYMER COMPOSITE FOR AUTOMOTIVE APPLICATION

FUDMA JOURNAL OF SCIENCES
The Periwinkle shell (Tympanotonus fuscatus) is one of the most abundant wastes in the Calabar coastal region of  Nigeria and needs to be put into proper use. The great need to shift attention towards waste materials with good mechanical properties to replace some materials used in the Automobile industries for Automobile products is paramount.

Cymbopogon nardus Leaf Ash as an Alternative Material for Enhancing Concrete Strength

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Numerous waste materials containing calcium and silica have been adopted as partial cement substitutes. This practice is intended to reduce the environmental impact of cement production, specifically in terms of carbon dioxide (CO2) emissions. However, plantation waste, specifically waste from Cymbopogon nardus leaf, has not been completely exploited ...

Analyzing the Mechanical, Durability, and Microstructural Impact of Partial Cement Replacement with Pumice Powder and Bamboo Leaf Ash in Concrete

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
This study explores the physiomechanical and durability properties of C‐25 concrete by partially replacing cement with blends of pumice powder (PP) and bamboo leaf ash (BLA). The combined amount of major oxides SiO2, Al2O3, and Fe2O3 in PP is 84.59%, while in BLA, it is 74.4%, classifying PP and BLA as class N and F pozzolans.

Comparative Evaluation of Concrete Properties with Varying Proportions of Periwinkle Shell and Bamboo Leaf Ashes Replacing Cement

Ethiopian Journal of Environmental Studies and Management, 2013
The paper examined the performance of ternary blended cement concrete incorporating periwinkle shell ash (PSA) and bamboo leaf ash (BLA) as cement supplements. PSA and BLA were obtained by burning periwinkle shell and bamboo leaves in a furnace at a temperature of 600oC for 20 minutes. The chemical analysis of the ashes revealed that they are amorphous
