These materials blend order and disorder, making their structures difficult to describe and, thus, reproduce. Their practical design involves the approximate replication of geometries found in biological tissues, aiming to achieve desired functionalities using a diverse array of human-made molecular and nanoscale components. Although this approach led to the successful development of numerous high-performance nanocomposites, the rapidly growing demand for better and better materials in energy, water, health and other technologies necessitates an accelerated design process, multidimensional property assessment and, thus, a shift towards quantitative biomimetics. In this Perspective, we approach the design of complex bioinspired materials from the standpoint of interfacial chemistry and physics. Analysing typical examples of biological composites and their successful replicates, we propose a framework based on Taylor series and property differentials that quantifies their interdependence. Five specific cases are considered for limiting their cross-products in Taylor expansions, including discontinuities of differentials at interfaces and multiple scales of organization. We also discuss how the integration of theory, simulations and machine learning is central to the development of quantitative biomimetics. This approach will enable the <i>n</i>-dimensional optimization of contrarian properties by leveraging materials with a high volumetric density of interfaces, graph theoretical description of complex structures and hierarchical multiscale architectures.</p>","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"27 1","pages":""},"PeriodicalIF":83.5,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142788681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional artificial vision systems (AVS) are hindered by several limitations, including narrowed field of view, optical aberrations, limited adaptability and suboptimal efficiency. Advancements in nanomaterials have facilitated the development of biomimetic optoelectronics that structurally or functionally mimic biological eyes. Two main approaches have revolutionized AVS: biomimetic designs that replicate the superior optical performance of biological eyes, enhancing the field of view, imaging quality and adaptability, and neuromorphic optoelectronics that integrate processing functions at the sensory endpoints, thus boosting computational and energy efficiency. This Review emphasizes nanomaterial-based biomimetic optoelectronics, featuring novel curved image sensors and neuromorphic devices. We delve into advanced nanomaterials and innovative design strategies that underpin these novel AVS.

{"title":"Binding energy referencing in X-ray photoelectron spectroscopy","authors":"Grzegorz Greczynski,&nbsp;Lars Hultman","doi":"10.1038/s41578-024-00743-5","DOIUrl":"10.1038/s41578-024-00743-5","url":null,"abstract":"Binding energy (BE) referencing is critical to the reliability of chemical analysis performed by X-ray photoelectron spectroscopy. Although the procedure is straightforward for metallic samples, no universal solution is available for insulators, wherein a build-up of positive charge during photoemission results in an uncontrolled change in the BE of the core-level peaks. As these peaks are used to assess the chemical bonding, shifts caused by charging lead to problems with spectra interpretation and contribute to an unacceptably large spread in the BE values reported for the same chemical state. It is often unclear which referencing methods should be applied to which sample type and which referencing approaches should be rejected. In this Perspective, we review essential concepts and key experiments related to BE referencing. We discuss energy diagrams and appropriate reference levels for conducting and insulating samples with and without electrical contact with the spectrometer, and we define criteria for the ultimate charge-reference method, using them to evaluate common referencing techniques. Although no method is free of issues, the most popular one, based on the adventitious carbon (AdC), turns out to be the least reliable. In particular, because the vacuum level aligns at the AdC–sample interface, the BE of the reference C 1s peak from AdC is not constant but varies with the sample work function. To rectify the situation, we suggest easy-to-do control experiments that refute the notion that the C 1s peak has constant BE. We further use the framework of energy diagrams to explain the consequences of the vacuum level alignment at the AdC–sample interface for measurements performed in the most common experimental configurations. Finally, we suggest ideas for improving the reliability of chemical analysis to stimulate the development of new referencing standards. Binding energy referencing is critical for the reliability of chemical analysis performed by X-ray photoelectron spectroscopy. This Perspective discusses the essential concepts related to this procedure and formulates the criteria for the ultimate charge reference, using them to expose problems with the existing referencing methods with the goal of stimulating the development of new approaches.","PeriodicalId":19081,"journal":{"name":"Nature Reviews Materials","volume":"10 1","pages":"62-78"},"PeriodicalIF":79.8,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Review, by regarding metal NCs as metallic analogues of organic molecules, we summarize methodological and mechanistic advances in their precise synthesis at the molecular and atomic levels. We first decipher cluster structure based on a protein-like hierarchical scheme and discuss synthetic strategies that realize molecular monodispersity in these clusters. We resolve formation mechanisms of metal NCs at the molecular level, aiming to establish step-by-step reaction maps reminiscent of total synthesis routes of organic molecules. We then examine approaches to customize the composition and morphology of the metal core, metal–ligand interface and ligand shell at the atom level.
