Tremendous progress has been made in the employment of two-dimensional (2D) nanomaterials in cement composites. However, high cost and poor dispersion of 2D nanomaterials immensely hinder their extensive use. To address these issues, in this work, a scalable, simple, and eco-friendly graphene quantum dots (GQDs)-assisted ultrasonic exfoliation appr...

Carbon dots (CDs) have been demonstrated to be a novel, green and effective corrosion inhibitor. Nevertheless, it still remains an enormous challenge to obtain CDs corrosion inhibitors by an energy-efficient and time-saving way. Meanwhile, there is no investigation to evaluate the inhibition effect of CDs with Schiff base structures. To surmount th...

Carbon dots (CDs), a rising star in carbon nanomaterials, have attracted enormous attention since their discovery in 2004. Up to now, a large number of approaches have been developed to synthesize CDs, and many efforts have been made to exploit facile, low-cost and large-scale preparation routes. At the same time, photoluminescence (PL) mechanisms...
