“…In this regard, the field of NP self-assembly is realizing its potential for the development and manufacturing of materials and devices with important properties which otherwise are not available, or are limited by the cost. The present status of the field suggests that self-assembled materials are gaining ground in chemical separations, electronics, photonics, and energy storage and conversion. − In a recent study, Xu, Klajn, Kotov, Kuang, and co-workers designed polarization-sensitive optoionic membranes from self-assembled chiral plasmonic NPs (Figure a, b) . It is quite challenging to achieve optoelectronic effects that can differentiate between absorption of circularly polarized lights, and hence often necessitates the use of chiral metasurfaces having out-of-plane architecture.…”

The creation of matter with varying degrees of complexities and desired functions is one of the ultimate targets of self-assembly. The ability to regulate the complex interactions between the individual components is essential in achieving this target. In this direction, the initial success of controlling the pathways and final thermodynamic states of a self-assembly process is promising. Despite the progress made in the field, there has been a growing interest in pushing the limits of self-assembly processes. The main inception of this interest is that the intended self-assembled state, with varying complexities, may not be “at equilibrium (or at global minimum)”, rendering free energy minimization unsuitable to form the desired product. Thus, we believe that a thorough understanding of the design principles as well as the ability to predict the outcome of a self-assembly process is essential to form a collection of the next generation of complex matter. The present review highlights the potent role of finely tuned interparticle interactions in nanomaterials to achieve the preferred self-assembled structures with the desired properties. We believe that bringing the design and prediction to nanoparticle self-assembly processes will have a similar effect as retrosynthesis had on the logic of chemical synthesis. Along with the guiding principles, the review gives a summary of the different types of products created from nanoparticle assemblies and the functional properties emerging from them. Finally, we highlight the reasonable expectations from the field and the challenges lying ahead in the creation of complex and evolvable matter.

Self-assembly offers unique possibilities for fabricating nanostructures, with different morphologies and properties, typically from vapor or liquid phase precursors. Molecular units, nanoparticles, biological molecules and other discrete elements can spontaneously organise or form via interactions at the nanoscale. Currently, nanoscale self-assembly finds applications in a wide variety of areas including carbon nanomaterials and semiconductor nanowires, semiconductor heterojunctions and superlattices, the deposition of quantum dots, drug delivery, such as mRNA-based vaccines, and modern integrated circuits and nanoelectronics, to name a few. Recent advancements in drug delivery, silicon nanoelectronics, lasers and nanotechnology in general, owing to nanoscale self-assembly, coupled with its versatility, simplicity and scalability, have highlighted its importance and potential for fabricating more complex nanostructures with advanced functionalities in the future. This review aims to provide readers with concise information about the basic concepts of nanoscale self-assembly, its applications to date, and future outlook. First, an overview of various self-assembly techniques such as vapour deposition, colloidal growth, molecular self-assembly and directed self-assembly/hybrid approaches are discussed. Applications in diverse fields involving specific examples of nanoscale self-assembly then highlight the state of the art and finally, the future outlook for nanoscale self-assembly and potential for more complex nanomaterial assemblies in the future as technological functionality increases.

“…Note that while the possibility of a large-scale and porous SEI layer has been previously discussed in some of the SEI growth models, cryo-EM allowed direct observation of this previously proposed SEI structure. 26 , 40 , 41 , 42 Interestingly, instead of both layers forming on the same particle, the compact and extended SEI layers are observed on separate particles. Cryo-EM characterizations of both layers further indicate that the lack of inorganic crystalline SEI particles in extended SEI might be the reason for its poor passivation.…”

“…Extended SEI is critical to the battery’s performance as such large-scale SEI growth greatly contributes to the Li inventory loss during cycling and is detrimental to the lithium-ion transport. 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 However, these structures have been previously overlooked because they can be easily removed by the washing and drying sample preparation steps common in other characterization techniques. Cryo-EM is able to preserve the native state of these extended SEI structures by vitrifying the solid-liquid interfacial structures, thus allowing researchers to better probe the nanoscale features at the interface.…”
