Summary: We numerically investigated the clustering of finite-size disks in a linear array of two-dimensional convection cells. The disks tend to form coherently rotating structures at the center of each cell due to steric interactions and pair collisions. Different patterns emerge depending on the suspension density, but thermal fluctuations dissolve them. Pair collisions activate cell crossings and cause athermal diffusion even by noiseless disks. The robustness of these collision induced effects is studied against thermal noise, transverse biases, and particle self-propulsion.

Summary: Inorganic CsPbI2Br halide perovskites are extensively studied as absorber layers for solar cells due to their high thermal and phase stability. However, CsPbI2Br solar cells face challenges including poor film morphology, large energy offset at the interfaces with charge transporting layers or carbon electrodes, large tensile strain, and degradation caused by hygroscopic dopants in the hole transporting layer. This review provides fundamental knowledge on CsPbI2Br perovskites and reviews the recent developments in CsPbI2Br perovskite solar cells through film optimization, charge transporting layer optimization, interface engineering, etc. The authors discuss the challenges, optimization methodologies, and present conclusions and future outlook for developing highly efficient and stable CsPbI2Br solar cells.

Summary: Atoms serve as an inspiration for colloidal self-assembly, allowing building blocks to combine and confer functionality through principles like directionality, valence, and reversible binding. Tetrahedral structures inspired by carbon atoms bonding are now accessible through molecular mimetic colloidal building blocks. Complex colloidal particles can be synthesized and arranged in their own periodic table, leading to diverse assembly routes based on unique particle shape and surface chemistry.

Summary: We present a solvable model to study the time-dependent spreading of partially wetting droplets on a substrate. The model considers both small droplets driven by capillarity and large droplets driven by gravity. We measure the equilibrium radius vs droplet volume for various household fluids and compare the results with predictions based on energy minimization, finding good agreement. We then develop equations of motion for the spreading dynamics, taking into account the forces balance inside the droplet and at the moving contact line. Our approach successfully describes prior data for capillary-driven droplets and fits well to new data for gravity-driven droplets.

Summary: Colloidal microcontainers, such as hollow capsules and colloidosomes, can be created through a self-assembly approach to encapsulate cargo particles within well-defined porous membranes or cages. The process involves camouflaging the cargo within a liquid matrix and forming densely packed shells around it. The self-standing cages are formed by fusing satellite particles, and the liquid matrix is then dissolved to trap the cargo. The porosity of the cages can be controlled by adjusting the fusion protocol. This technique has potential applications in transmembrane transport phenomena, such as delivering nanoparticles.

Summary: Researchers investigate nontrivial topological phases in arrays of interacting gyroscopes using experiments, numerical simulations, and analytic tools. They propose a general method for predicting the existence of band gaps and approximating the Chern number based on local features to avoid costly diagonalization of the system dynamics matrix. The study also reveals interactions between strong disorder and band topology in gyroscopic metamaterials, showing similar critical behavior to periodic lattices, and identifies a topological Anderson insulation transition caused by disorder.

Summary: This method involves the large-scale fabrication of bowl-shaped colloidal particles using an emulsion templating technique, where compliant seed particles are deformed by surface tension on oil droplets as templating surfaces. By adjusting droplet size and seed particle diameter, the final particle shape can be precisely controlled, ranging from shallow lenses to deep bowls. The resulting uniformly-shaped colloidal particles allow for depletion-mediated assembly of flexible colloidal chains and clusters.
