Zemin Zheng,Huiyong Li,Xudong Zhang,Hao Jiang,Xuemin Geng,Simin Li,Hongyu Tu,Xinran Cheng,Peng Yang,Yanfen Wan +9 more
TL;DR: In this article, an innovative 3D nanocomposite Au@Bi2MoO6-carbon dots (CDs) solar steamer has been prepared: it exhibits outstanding light absorption of 70%, a photothermal conversion efficiency of 97.1% and an evaporation rate of 1.69 kg m-2 h-1 under one sun illumination.
Journal ArticleDOI
Mechanical Properties of Au Supracrystals Tuned by Flexible Ligand Interactions
Mélanie Gauvin,Mélanie Gauvin,Yanfen Wan,Yanfen Wan,Imad Arfaoui,Imad Arfaoui,Marie-Paule Pileni,Marie-Paule Pileni +7 more
TL;DR: In this paper, the properties of face cubic centered colloidal crystals obtained out of equilibrium by solvent evaporation of coated Au nanocrystals suspension, called supracrystals, are reported as a function ligand chain length (n) and interparticle edge-to-edge distance within the supracerystals (δpp) for two nanocrystal sizes.
Journal ArticleDOI
Hierarchy in Au Nanocrystal Ordering in a Supracrystal: II. Control of Interparticle Distances
TL;DR: It is shown that the interparticle distance is independent of the supracrystal growth mechanisms, which is explained by the influence of depletion forces created by the presence of thiol-containing molecules physisorbed on the coating molecules on the internal structure of these suprachrystals.
Journal ArticleDOI
Substrate effects on the CVD growth of MoS2 and WS2
TL;DR: In this paper, the morphology, crystalline quality and optical properties have been modified while changing substrates, which can be derived from lattice matching between 2D materials and substrate, defect/impurities on the interface and conductance/transparency of different substrates.
Journal ArticleDOI
Integrated multifunctional device based on Bi2S3/Pd: Localized heat channeling for efficient photothermic vaporization and real-time health monitoring
TL;DR: In this article, a highly efficient solar evaporator is achieved by an innovative solar absorber (Bi2S3/Pd composite) owing to excellent photothermal conversion performance.
