Cathodes, crucial for determining capacity and voltage, face challenges like degradation in the form of thermal runaway and battery failure. Understanding these degradation phenomena is vital for developing mitigation strategies. Experimental techniques such as XAS, XPS, PES, UV–Vis, RIXS, NMR, and OEMS are commonly used, but theoretical modelling, particularly atomistic modelling with density-functional theory (DFT), provides key insights into the microscopic electronic behaviours causing degradation. While DFT offers a precise formulation, its approximations in the exchange-correlation functional and its ground-state, 0K limitations necessitate additional methods like ab initio molecular dynamics. Recently, many-body electronic structure methods have been used alongside DFT to better explain electron–electron interactions and temperature effects. This review emphasizes material-specific methods and the importance of electron–electron interactions, highlighting the role of many-body methods in addressing key issues in cathode degradation and future development in electron–phonon coupling methods.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"59 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A phenomenon that leads to the formation of these structures in thin films is diffusion-limited aggregation. The assumption in diffusion-limited aggregation is that formation of such structures is independent of the source conditions and relies only on film-substrate interactions with requirement of single crystallinity in both cases. The possibilities of fractal structures occurring in amorphous or crystalline film-on-amorphous or crystalline substrate have received limited attention. However, results on sputter deposited transition metal nitride thin films show that these combinations can indeed lead to fractal structures such as dendrites and snowflakes. In this work we postulate that the formation of these microstructures is perhaps related and sensitive to the initial conditions provided for growth, which leads to a conclusion that perhaps chaos-related dynamics is at work. We believe that a new theoretical framework is required to explain these phenomena. An attempt to identify the knowns and the unknowns in this area is made using our results as well as some available in the literature.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"701 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective of this work is to provide scientific clarifications regarding the relevance of Garvie factor for important doped zirconia systems. With the commercially popular compositions of yttria-stabilized zirconia (YSZ) systems, our results illustrate no relevance of a Garvie criterion for YSZ systems (for yttria doping ≥ 2.5 mol.%). The same was found to be true for ceria (12–20 mol.%)-doped zirconia (CeTZP) systems. The Garvie criterion seems to be strongly system dependent as it was found to be valid for tetragonal CaO-doped (3–4 mol.%) zirconia (CaSZ) systems. Contrary to a ‘consolidation factor’ that was credited for stabilization of tetragonal CaSZ ceramic, an opposite trend (between grain and particle size) was observed for YSZ and CeTZP systems. This was explained in terms of their possible difference and crossover between their respective surface and grain boundary diffusion parameters.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"49 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being assembled upon stimuli-responsive materials, the state-of-the-art soft actuators are presumed to not only perform complex robotic tasks, but also to be repaired after mechanical damage or long-term usage. Although meeting these requirements could be a challenge for actuators based on traditional thermosetting/thermoplastic elastomers, soft actuators built on restructurable materials can be an alternative, since both the actuation and healing functions rely on the stimuli-responsive structural rearrangement of these materials. Specifically, self-healing polymers have been demonstrated to be promising candidates for assembling restructurable actuators. This paper summarizes the reprogramming pathways of stimuli-responsive actuators; reviews the design strategies for constructing reprogrammable mono-layered actuators with the various types of dynamic polymer networks, especially with self-healing polymers; the design strategies for assembling bi- or multi-layered actuators with tailored interfacial structure, and proposes the outlook for the development of restructurable actuators.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":16306,"journal":{"name":"Journal of Materials Research","volume":"36 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
