Abstract:
... The so-called coffee-ring effect (CRE) is extraordinarily common, problematic in industry and attractively puzzling for researchers, with the accepted rule that it requires two key-ingredients: solvent evaporation and contact line pinning. Here, we demonstrate that the CRE also occurs when the solvent of a pinned sessile drop transfers into another liquid, without involving any evaporation. We sho ...

Herein, we report the controllable synthesis of CsₓPbyBrz-based perovskites by a simple polar solvent-triggered (H₂O, CH₃OH) chemical transformation method. The phase of CsₓPbyBrz-based perovskites can be successfully converted from Cs₄PbBr₆ ...

Abstract:
... The extraction of blueberry anthocyanins with natural deep eutectic solvents (NADES) based on choline chloride:glycerol:citric acid was optimized by simplex centroid design to find the best molar ratio for the solvent. Choline chloride:glycerol:citric acid at the molar ratio of 0.5:2:0.5 (NADES 6) was the optimal NADES for extraction. NADES 6 was as efficient as the conventional organic solvent (m ...

Abstract:
... Black phosphorus is currently among the most explored two-dimensional (2D) materials. Currently, the synthesis methods are dominantly based on vapor-phase growth of black phosphorus. In this manuscript, we demonstrate large-scale synthesis of black phosphorus by rapid high-pressure transition of red phosphorus. The high-pressure conversion of red phosphorus led to high-density nanocrystalline blac ...

Abstract:
... Establishing that a nanoparticle dispersion can, in fact, be treated as a solution has an important practical ramification, namely the application of solubility theories for solvent selection. However, what distinguishes a solution and dispersion has remained ambiguously understood. Based on the recent progress in statistical thermodynamics on multiple-component solutions, here we establish the co ...
