Reinhard Pippan, retired vice director and group leader at the Erich Schmid Institute, has devoted his career to exploring the mechanical properties of metals, alloys, and composites. His work spans the realms of plastic deformation, fatigue and fracture, as well as micro- and nanomechanics, with a strong focus on severe plastic deformation (SPD), novel nanostructured materials that can be synthesized by this, as well as uncovering their sometimes rather unexpected deformation and failure mechanisms.&lt;/p&gt;&lt;p&gt;Reinhard's journey in academia began with his education in physics at the Technical University Graz, culminating in a PhD from the Montanuniversität Leoben in 1982 under the supervision of Prof. H.P. Stüwe. His career has been predominantly associated with the Erich Schmid Institute (ESI) of Materials Science of the Austrian Academy of Sciences, where his research has flourished. Reinhard has been instrumental in introducing discrete dislocation mechanics to fracture and fatigue, leading to a deeper understanding of fatigue crack propagation and fracture processes. For the first 20 years of his career, this remained his main focus and led to significant impacts in these fields.&lt;/p&gt;&lt;p&gt;Driven by the idea that nanostructured materials should possess outstanding fracture and fatigue properties, Reinhard entered the field of severe plastic deformation (SPD) with the intention to synthesize such materials at ESI. Even though in the early days several SPD-techniques, such as equal channel angular pressing (ECAP), were already available at ESI, he early recognized the advantages of high pressure torsion for basic research work, rooted in the simplicity of the process and the extensive accessible parameter space. At the beginning, his main interest targeted the microstructural processes leading to ultrafine and nanograined structures, the limits of grain refinement and the underlying structure property relationships. His further advancements in the HPT-technology have created pathways to synthesize novel materials, for example super-saturated solid solutions, placing his SPD group at the forefront of this rapidly evolving field. Additionally, Reinhard placed great efforts in the upscaling of the process and made first steps into industrial applications of the HPT-technique.&lt;/p&gt;&lt;p&gt;Due to the limited material quantities available by SPD deformation and the need to better understand the uncommon mechanical properties of ultrafine-grained and nanostructured materials, the scope of Reinhard's research in the last twenty years extended into the micro- and nanomechanics domain, where his pioneering visions in micromechanical testing have set new standards. This encompasses for example the discrete dislocation based deformation of confined sample vol","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202401772","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The porous structure formed by selective laser melting technology offers many advantages, but it also presents some challenges, for instance, how to how to ensure that the density is greatly reduced without sacrificing the material's mechanical properties. The Schoen I-graph-wrapped package structure with different cell sizes under the same volume fraction had been designed and fabricated by selective laser melting technology using CuCrZr powder as the raw material. The microstructure, grain orientation, and static properties were explored. At the same volume fraction, the pores were almost completely blocked when the cell size was 2 mm, with reduced powder adhesion when the cell size was 9 mm. As the cell size decreases, the compressive strength increases, with the compressive strength reaching 180 MPa at a cell size of 2 mm. Moreover, the energy absorption efficiency increases with the increase in cell size, with the highest energy absorption efficiency of 28% at a cell size of 9 mm. The limit dimensions under these conditions were determined to provide a reference for related research in this field.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267988","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}

However, it faces critical challenges throughout the cryopreservation process, such as loading/unloading of cryoprotective agent (CPA), ice inhibition during cooling, and ultrafast and uniform heating during rewarming. Applying nanomaterials in cryopreservation has emerged as a promising solution to address these challenges in each step due to their unique properties. For instance, in order to deliver nonpermeating CPA into cells, some nanomaterials, such as polymeric nanocapsule, can carry nonpermeating CPA to penetrate into the cells, regulating the intracellular ice crystal. During cooling, some nanomaterials, such as graphene oxide, can bind to basal or prism planes of ice crystals, suppressing the ice growth. During rewarming, some nanomaterials, such as magnetic nanoparticles, can improve the heating performance, preventing devitrification and recrystallization during rewarming. However, challenges in nanomaterials-assisted cryopreservation remain, including the need for comprehensive studies on nanomaterials toxicity and the development of scalable manufacturing processes for industrial applications. This review examines the role of nanomaterials in cryopreservation, focusing on their mechanisms, applications, and associated challenges.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142267946","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}
