Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Performance of Light Weight Concrete with Coconut Shell and Fly Ash

International Journal for Research in Applied Science and Engineering Technology, 2021
Abstract: The major factor that affects the housing delivery is high cost of materials for any conventional concrete. This has lead to find an alternative. An attempt has been made to find an alternative by using partial replacement of coarse aggregate by coconut shell aggregate and cement by fly ash.

Basic Experimental Studies on Coconut Shell Charcoal Ash in Modified Bitumen [PDF]

Materials Research Proceedings, 2021
Abstract. For reducing the cost in bitumen roads and also increasing the efficiency of bituminuous roads, varieties of materials are used for improving the road by using coconut shell charcoal ash as fillers in the flexible pavement. In the literature work, the main descriptive of the work is to compare the results with different percentages of coconut

Utilization of Coconut Shell Ash as a Substitute Material in Paving Block Manufacturing

IOP Conference Series: Earth and Environmental Science, 2022
Abstract In this study, coconut shell ash (CSA) was used as a substitute for cement in the manufacture of paving blocks. The research aims to determine the CSA substitution effect on the mortar compressive strength. The replacement percentages were 0, 3, 5, 8, 10, and 12%.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
