(1) Background: In time, stone monuments suffer a process of aging and loss aesthetic mechanical properties. order to restore stop the their properties, various treatments are used, in this context, new class discovered materials with interesting properties layered double hydroxides, or LDHs. (2) Methods: The LDHs, prepared by coprecipitation method, were characterized structure X-ray diffracti...

Layered double hydroxides (LDHs) are a class of two-dimensional (2D) clay compounds that consist positively charged host layers and exchangeable interlayer anions. The stability their assemblies in aqueous environment is challenge due to the extremely high hydrophilicity, which limits use membrane-based technologies. Here, we propose graphene oxide (GO) armour protection strategy substantially ...

Graphene quantum dots (GQDs) have received much research attention due to their unique optical/electrical/magnetic features. However, the intrinsic relationship between the structure and properties of GQDs remains not fully understood, because the controlled synthesis and the accurate structure determination of GQDs are still a great challenge. Here, single-layered GQDs are successfully obtaine...
