Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Effects of aggregates on the mechanical properties and microstructure of geothermal metakaolin-based geopolymers

open access: yesResults in Physics, 2018
Geothermal clay rich in kaolinite was first prepared into geopolymers in the preparation of alkali-activated cementitious binders (AACBs). Effects of silica sand and steel fiber aggregates on the microstructure and mechanical strength of the geothermal ...

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

open access: yesCarbon 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.

The Role of Awareness in Sustainable Construction Materials Uptake in Developing Economies: Evidence From Nigeria

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainable Construction Materials (SCM) are crucial for reducing lifecycle emissions in the built environment, yet their adoption remains limited in many developing economies, such as Nigeria. This study investigates how awareness influences the adoption of SCM among professionals in Nigeria's Architecture, Engineering, and Construction (AEC)
