Summary: Using different evaporation rates of the dispersion solvent, controlled assembly of CsPbBr3 nanoplatelets was achieved. Electron microscopy, X-ray scattering, and diffraction confirmed the superlattice structures in both the face-down and edge-up configurations. Polarization-resolved spectroscopy revealed significantly polarized emission in the edge-up superlattices compared to the face-down counterparts. Variable temperature X-ray diffraction revealed a uniaxial negative thermal expansion in ultrathin nanoplatelets, explaining the anomalous temperature dependence of the emission energy. Additional structural aspects were investigated by multilayer diffraction fitting, showing a decrease in superlattice order and an expansion of the organic sublattice and lead halide octahedral tilt with decreasing temperature.

Summary: The self-assembly of platy clay particles is influenced by the anisotropic surface charging properties of the particles, which can be controlled by solution pH. By adjusting pH, desired nanostructures can be formed through self-assembly of clay particles. This pH-dependent self-assembly can also be applied to other platy particles with anisotropic surface properties.

Summary: Cadmium chalcogenide nanoplatelets have a high affinity to self-assemble into ordered stacks from organic solvents through the addition of polar antisolvents. In this study, a new synthesis route is introduced to directly self-assemble the nanoplatelets into stacks in aqueous media by adding non-polar antisolvents. The mechanism of stacking and possible driving forces are analyzed using various measurements.

Summary: The study investigates the influence of external magnetic fields on the anisotropic collective dynamics of core/shell colloidal cubes with hematite cores and silica shells. Results show that these micrometer-sized particles self-assemble into chains and sediment to form higher-order structures, with dynamics following compressed exponential behavior in different directions with respect to the external field, indicating hyperdiffusive behavior. The anomalous dynamics are believed to be caused by the inhomogeneous distribution of stress points resulting from external field-induced alignment of chains.

Summary: A novel 2D-2D bentonite/g-C3N4 composite with a layer-layer cross structure and large surface area was successfully synthesized for the photocatalytic oxidation of arsenic in wastewater. The composite exhibited a significantly higher As(III) oxidation rate compared to pure g-C3N4, attributed to the enhanced specific surface area and suppressed electron-hole recombination. Additionally, the composite showed high photocatalytic oxidation efficiency over a wide pH range.

Summary: This study reports the first discovery of stable bulk bassanite precipitated in solution, filling the gap in the calcium sulfate phase diagram. By precisely controlling water activity and using a polymer, bulk bassanite is formed instead of transforming into thermodynamically favorable gypsum. A new thermodynamic model of the non-classical crystallization process is proposed, and molecular dynamics simulation demonstrates the role of water molecules in initiating the assembly and growth of bassanite.

Summary: This study proposes a novel design of Cu(I) active sites based on metal-organic framework (MOF) to capture OH- produced via Fenton-like processes and re-coordinate oxidized Cu sites, aiming to achieve high catalytic activity and stability. The Cu(I)-MOF exhibits excellent removal efficiency for sulfamethoxazole (SMX), with a high removal kinetic constant of 7.146 min-1. Through combining DFT calculations with experimental observations, it is revealed that the Cu of Cu(I)-MOF exhibits a lower d-band center, enabling efficient activation of H2O2 and spontaneous capturing of OH- to form Cu-MOF, which can be reorganized into Cu(I)-MOF through molecular regulation for recycle. This research demonstrates a promising Fenton-like approach for solving the trade-off between catalytic activity and stability and provides new insights into the design and synthesis of efficient MOF-based catalysts for water treatment.

Summary: This paper investigates the influence of noise effects, particle size, and sampling time on total internal reflection microscopy (TIRM) measurement results. It finds that detector shot noise and prolonged sampling times may cause erroneous results in steep parts of the interaction potential, while background noise has negligible effects. Noise does not significantly affect dynamic data, but lengthy sampling times and small probe particle radii can cause issues. Additionally, the study observes that dynamic results may differ from standard hydrodynamic predictions due to partial slip.

Summary: The near-wall Brownian dynamics of different types of colloidal particles were investigated, revealing that rough particles diffuse significantly slower compared to smooth particles. This difference in dynamics is attributed to the rough particles significantly changing their DLVO interaction with the wall, affecting their diffusion.

Summary: This study introduces a MPC implementation for layered immiscible fluids, exhibiting accurate flow profile simulations and shear stress functions. Additionally, the model is capable of determining the hydrodynamic mobilities of colloidal spheres near fluid-fluid interfaces. While computationally efficient, the model may not reproduce all hydrodynamic features of an ideally flat interface between immiscible fluids.

Summary: The study quantitatively determined the content of interfacial and bulk water in the parental microemulsions using FTIR spectroscopy, and investigated the nucleation and growth of PbCrO4 nanoparticles in the microemulsions. By controlling the water ratio in micellar droplets, the researchers were able to obtain amorphous nanoparticles in the interfacial water and nanocrystals in the bulk water. The amorphous nanoparticles with defined shapes were found to be stable in the microemulsion solution and did not transform into crystallites for several days, offering a method to control the metastable amorphous precursor for follow-up crystallization.
