Composite protective coatings are critical for material durability but face challenges like fragmented knowledge and scalability issues. Existing research lacks the systematic integration of nanomaterial properties with macroscale performance and standardized evaluation protocols for hybrid systems. This study uses CiteSpace to analyze 18,363 publi...

Background The gaseous detonation method is a promising method for the rapid and large-scale preparation of graphene quantum dots (GQDs). However, the relationship between detonation parameters and the morphological and optical properties of GQDs remains unclear and needs further investigation. Methods This study systematically investigates the in...

Chloride binding technology can effectively reduce the content of free chloride ions in seawater (used for cementitious materials), thereby extending the service life of seawater concrete structures. Currently, affordable and highly dispersed nanomaterials that can enhance the chloride binding capability of seawater cement are finite. This paper pr...

Chloride-caused corrosion of reinforcing steel is a dominant factor in the durability degradation of reinforced concrete (RC) structures. Nevertheless, there remains a deficiency in suitable additives to augment the resistance of RC structures against chloride-induced corrosion. In light of this, a novel nanomaterial (i.e., polymer dots (PDs)) with...

Carbon dots (CDs) as a newfangled and eco-friendly nanomaterial exhibit a promising engineering application in strengthening mechanical properties of cement matrices. However, the modification effectiveness of CDs on mechanical performance lacks enough investigation. More seriously, the influence of their sizes is still a research gap, enormously h...

Nanomaterials have made significant progress in the field of cementitious materials, but suffer from primary problems of high cost and poor dispersity. Carbon dots (CDs) as a novel low-cost and high-dispersity nano-material preliminarily demonstrate their potential for cement. Nevertheless, it lacks systematic research on their effects on cement pr...

This study investigated the influence of microbead dosages (0, 5, 10, 15, and 20%) on the frost resistance of expanded polystyrene (EPS) concrete. Five groups of EPS concrete specimens were prepared and subjected to rapid freeze–thaw tests. The freeze–thaw deterioration of EPS concrete was assessed using macroscopic indicators, including mass loss,...

Tremendous progress has been made in the employment of two-dimensional (2D) nanomaterials in cement composites.

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...

Corrosion inhibitors as the most important component play a crucial role in the quality of pickling solution. Carbon dots (CDs) have been demonstrated to be a novel and efficient corrosion inhibitor.

This work aims to propose a new method to overcome the shortcomings of slow setting and low early strength occurring in cement-based composites with high-volume fly ash (HVFA). The effects of binary system containing calcined hydrotalcite (CHT) and Na2SO4 (NS) on early strength, hydration process, pore structure and microstructural morphology of HV...

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...

Carbon dots (CDs) have opened up a new field of carbon nanomaterials and successively attracted increasing attention since their discovery in 2004.
