For example, coral reef is able to accumulate reinforcing calcium carbonate from wave agitation and water current that stabilizes gaps in the structure and increases the reef density and strength through diagenetic reef cementation. Bone responds to repeated stress by translating deformations and fluid movement in the bone matrix into cellular signals that trigger bone formation through mechanotransduction. Utilizing these mechanisms as inspiration, synthetic materials have been developed that utilize stress-generated piezoelectric charges to attract mineral ions to form reinforcing mineral layers that can repair defects and damage over time and extend material lifetime. In this article, we examine natural adaptive processes that give inspiration for new synthetic materials with similar dynamic adaptive properties. We also introduce the capabilities of existing bioinspired synthetic materials, current challenges these systems face, potential application areas of this technology, and future research opportunities of these adaptive materials.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ensuring their sustainable and safe use in hydrogen technologies is a key factor in the ramp-up of the hydrogen economy. This requires extensive materials qualification, however, most of the accepted; and standardized test methods for determining the influence of gaseous hydrogen on metallic materials describe complex and costly procedures that are only available to a very limited extent worldwide. The hollow specimen technique is a simple, rapid, and economical method designed to overcome the limitations of the current methods for the qualification of metallic materials under high-pressure hydrogen gas. However, this technique is not yet standardized. The TransHyDE-H2Hohlzug project is presented in this article, along with the main steps required to optimize the hollow specimen technique. This includes closing knowledge gaps related to the specimen geometry, surface quality, and gas purity in dedicated working packages, thus contributing to a comprehensive standardization of the technique for tests in high-pressure hydrogen gas.</p><h3 data-test=\"abstract-sub-heading\">Impact statement</h3><p>The hydrogen economy is considered a key solution for achieving climate neutrality in Europe, as it plays a crucial role in the decarbonization of sectors such as transport, industry, power, etc. Ensuring the safety and reliability of infrastructure is crucial for the ramp-up of the hydrogen economy. Therefore, it is necessary to meticulously study the materials and components used for infrastructure under conditions that closely resemble in-service conditions. The currently standardized methods are limited as they do not precisely replicate in-service conditions, and when they do, they are often complex, costly, and not easily accessible. This article presents the hollow specimen technique, a simple, and economical method developed to address the limitations of current standardized methods. The results from this work will contribute to the standardization of this technique for tests in high-pressure hydrogen gas. This will enable a faster evaluation of materials for hydrogen applications by industry and academia, thereby contributing to the growth of the hydrogen economy.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nano-sized Cu-rich nanoprecipitates improved the strength of alloys by hindering the movement of grain boundaries, revealing the disordering strengthening effect. Meanwhile, dense precipitates prevented grain growth, thereby improving grain refinement and further increasing the strength. Particularly, samples with Cu alloying exhibited a more pronounced grain refinement effect on grain-refined samples compared to ones without alloying, thus showing a more significant strengthening effect.

While recent advances in sequencing have yielded abundant insights, relatively little is known concerning post-translational modifications (PTMs) in spider silk. Here, we probe the PTM landscape of dragline silk from the Jorō spider (<i>Trichonephila clavata</i>) using a combination of mass spectroscopy and solid-state nuclear magnetic resonance (NMR). The results reveal a wide array of potential modifications, including hydroxyproline, phosphorylation, and dityrosine cross-links, encompassing the different spidroin constituents. Notably, the MaSp3 repetitive region displayed numerous PTMs, whereas MaSp1 and MaSp2 variants showed distinct phosphorylation patterns in its terminal domains. The N-terminal domain (NTD) phosphorylation sites were found predominantly at the dimer interface, suggesting a modulatory function with respect to its pH-driven dimerization function, a hypothesis supported by studies using phosphomimetic NTD mutants. Possible roles of phosphoserine in limiting β-sheet formation, and hydroxyproline in disrupting β-turns are also discussed.</p><h3 data-test=\"abstract-sub-heading\">Impact statement</h3><p>Spider silk is an archetypal biomaterial that can outperform our most sophisticated artificial fibers. The secret to its mechanical properties lies in its complex hierarchical structure—encompassing the nano- to macroscales—that forms through a process of molecular self-assembly of the constituent spidroin proteins. While recent advances in \"biomateriomics” have given us tremendous insights into the sequence–function relationships that determine spider silk behavior, the picture is still far from complete. One area that has received little attention is posttranslational modifications (PTMs). PTMs are ubiquitous biological phenomena that are crucial for providing dynamic control of the proteome, and effectively expand the structural and functional design space of proteins beyond that provided by the canonical amino acids. Here, we undertook a comprehensive analysis of PTMs from spider dragline silk fiber, which revealed numerous potential sites for a wide array of modifications. The results provide a fascinating window into additional layers of complexity underlying the mechanical behavior of spider silk, and suggest further avenues for creating novel, dynamically tunable, bioinspired materials.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":null,"pages":null},"PeriodicalIF":5.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are easily transported over long distances via fibers or even satellites due to their remarkably weak interaction with each other. Therefore, some sort of link between photons is required to carry out quantum operations. Ideally, this process is carried out on a robust solid-state chip infrastructure. In this context, excitons (i.e., bound electron–hole pairs in semiconductors) are an ideal connection between photons and the solid state. Due to their mostly strong dipole character, excitons can be efficiently created by photons and inversely create photons upon recombination. This makes excitons in various semiconductor platforms key players in modern quantum technology approaches. While in extended crystal systems, excitons can be transported, their confinement to quasi-0D is used to create stationary solid-state qubits. In addition, excitons provide interactions with other degrees of freedom that can be harnessed in quantum technologies (i.e., spin or mechanical excitations of the host crystal lattice). Here, we review different approaches that use static or dynamic strain to tailor the optical properties of excitons or provide transport channels for excitons.
