Geopolymers are presented as a chemically programmable platform whose properties emerge from activation chemistry, nanoscale disorder, and interfacial design. The review highlights sustainability challenges, the shift toward nanoengineered and hybrid systems, and the rise of halloysite‐based architectures enabling tunable structures across scales for ...

The influence of fly ash as substitute of cement in the durability of concrete [PDF]
Limitation of transport capacity through the concrete is one of the key points in the improvement of the material’s durability. The use of fly ash as an admixture to concrete is widely extended; a general consensus has been established due to the pore ...

Coal Mine Wastewater as a Secondary Resource: Advances in Treatment and Value Recovery Technologies
ABSTRACT Coal mine wastewater, which has historically been considered an environmental problem, is becoming more widely recognized as a secondary resource with substantial value recovery potential. Nevertheless, recent progress demonstrates that this wastewater could be converted into highly useful, industrially available pigments (like iron oxides) by

Unmothered at Work: Organizational Silence Around Reproductive Loss
ABSTRACT An identity transition refers to changes in self‐concept that can result from professional or personal shifts. Although organizations increasingly support institutionally legible and culturally normative nonwork transitions, others remain professionally stigmatized or culturally unspeakable.

ABSTRACT The use of supplementary cementitious materials (SCMs) is a major way to reduce the carbon footprint of concrete. Mechanochemical activation (MCA) can be used to activate inert materials that can then be used as SCMs. In this study, the effect of MCA using a planetary ball mill was investigated for 16 materials, ranging from natural occurring ...
