Although the geopolymer is generally regarded as a solution to low-carbon building materials, the intrinsic high brittleness greatly limits its further engineering practices. Here, we performed multi-scale ab-initio modeling and experiment on synergi

Abstract In this work, laser-induced breakdown spectroscopy (LIBS) was applied to qualitatively evaluate lead adsorbed from industrial wastewater by nano-CaCO3. Eggshell as a natural source of CaCO3 has been used as a sorbent owing to its low cost an
