Self-assembly fundamentally implies the organization of small sub-units into large structures or patterns without intervention specific local interactions. This process is commonly observed in nature, occurring at various scales ranging from atomic/molecular assembly to formation complex biological structures. Colloidal particles may serve as micrometer-scale surrogates for studying assembly, particularly poorly understood kinetic and dynamic processes atomic scale. Recent advances colloidal self-assembly have enabled programmable creation novel materials with tailored properties. We here provide an overview comparison both passive active self-assembly, a discussion on energy landscape interactions governing types. In realm many impressive important been realized, including molecules, one-dimensional chains, two-dimensional lattices, three-dimensional crystals. contrast, driven by optical, electric, chemical, other fields, involves more intricate processes, offering flexibility potential new applications. A comparative analysis underscores critical distinctions between assemblies, highlighting unique collective behaviors emerging systems. These encompass motion, motility-induced phase segregation, exotic properties arising out-of-equilibrium thermodynamics. Through this comparison, we aim identify future opportunities research, which suggest application domains.

High-Yield Synthesis of Colloidal Carbon Rings and Their Applications in Self-Standing Electrodes of Li–O₂ Batteries

Journal of the American Chemical Society, Год журнала: 2023, Номер 145(50), С. 27664 - 27671

Опубликована: Дек. 1, 2023

The use of carbon materials in porous electrodes has impressive advantages. However, precisely tailoring the multilevel pore structure remains an unsolved challenge. Here, we report a highly efficient site-selective growth strategy to synthesize colloidal rings by templating patchy droplets. Carbon are used for direct fabrication self-standing with hierarchical pores lithium-oxygen batteries (LOBs). In situ atomic force microscopy reveals that during discharge products densely nucleate and grow on rings, demonstrating such very potential electrode material LOBs. hollow ring (HCRE) possesses micrometer-scale channels formed random packing nanochannels consisting ring-shaped cavities connected nanosized wall. Both contribute ion transportation gas diffusion, but storage mainly lies channels, leading high capacity LOBs (20 658 mAh/g). Our work paves new way construct hierarchically application electrocatalysis electrochemical energy storage.

Опубликована: Сен. 24, 2024

Programming the organization of discrete building blocks into periodic and quasi-periodic arrays is challenging. Methods for organizing materials are particularly important at nanoscale, where time required processes practically manageable in experiments, resulting structures interest applications spanning catalysis, optics, plasmonics. While assembly isotropic nanoscale objects has been extensively studied described by empirical design rules, recent synthetic advances have allowed anisotropy to be programmed macroscopic assemblies made from blocks, opening new opportunities engineer even quasicrystals with unnatural properties. In this review, we define guidelines leveraging individual direct matter. First, nature spatial distribution local interactions considered three rules that guide particle derived. Subsequently, examples literature examined context these rules. Within discussion each rule, delineate according dimensionality (0D-3D) blocks. Finally, use geometric considerations propose a general inverse design-based construction strategy will enable engineering colloidal crystals unprecedented structural control.

Abstract When in equilibrium, thermal forces agitate molecules, which then diffuse, collide and bind to form materials. However, the space of accessible structures micron-scale particles can be organized by is limited, owing slow dynamics metastable states. Active agents a passive fluid generate flows, forming bath with active fluctuations. Two unanswered questions are whether those drive assembly components into unconventional states material properties they will exhibit. Here we show that passive, sticky beads immersed swimming Escherichia coli bacteria aggregate clusters gels controlled activity bath.
