This study investigates the influence of microplatelet orientation in composite materials, utilizing the magnetically assisted direct ink writing method (M-DIW) to create microstructured microplatelet-reinforced composites. Experimental and computational approaches are employed to explore the critical role of microplatelet orientation on the flexural properties of these materials. Horizontal microplatelets are found to significantly enhance the composite’s flexural toughness by promoting overlap and increasing fracture energy during crack propagation. Vertical microplatelets contribute to increased flexural modulus and strength. Perpendicular microplatelets facilitate straight crack paths and smoother fracture surfaces. Moreover, complex microstructural designs were introduced by strategically combining microplatelet orientations to optimize mechanical properties. These findings emphasize the vital role of microplatelet orientation in composite materials, offering potential for tailored materials with superior performance.</p> </span> <span> <h3>Impact statement</h3> <p>The findings of this research carry significant implications in the fields of materials science and engineering. By comprehensively examining the role of microplatelet orientation in composite materials, this study offers a novel perspective on how to optimize mechanical properties for various applications. The identification of distinct strengths and limitations associated with horizontal, vertical, and perpendicular microplatelet orientations enables the creation of tailored materials with enhanced mechanical performance. This customization potential holds considerable promise for industries that rely on composite materials, such as aerospace, automotive, and construction. Moreover, the introduction of hierarchical designs presents innovative avenues for engineering materials with superior properties. These designs showcase the potential to achieve a delicate balance between flexural toughness, strength, and modulus, allowing for materials that can outperform traditional monolithic structures. Ultimately, this research empowers materials scientists and engineers to make informed decisions regarding microplatelet orientation, enhancing the efficiency and versatility of composite materials across a wide range of industries. As a result, it brings us one step closer to a future where materials can be precisely tailored to meet the demands of specific applications, driving innovation and progress in diverse sectors.</p> </span> <span> <h3>Graphical abstract</h3> <p><span> <span> <img alt=\"\" src=\"https://static-content.springer.com/image/MediaObjects/43577_2024_670_Figa_HTML.png\"/> </span> </span></p> </span>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"129 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140037816","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}

Most of their movements rely on the movement of water into and out of their cells or tissues, which are intrinsically soft and porous. Understanding and harnessing these natural processes can lead to the development of environmentally friendly and biocompatible soft actuator systems. This article explains the strategies employed by plants to generate movement through water transportation, categorizing them into osmosis-driven and hygroscopic swelling-driven mechanisms. Additionally, we discuss the latest trends in soft actuators that replicate plant water-utilizing movements, suggest directions for further development, and provide a review of practical applications.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"178 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945933","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}

Currently, multiple classes of actuators can operate at the micron scale, be patterned using lithographic techniques, and be driven by complementary metal oxide semiconductor (CMOS)-compatible voltages, enabling new technologies, including digitally controlled micro-cilia, cell-sized origami structures, and autonomous microrobots controlled by onboard semiconductor electronics. This field is poised to grow, as many of these actuator technologies are the firsts of their kind and much of the underlying design space remains unexplored. To help map the current state of the art and set goals for the future, here, we overview existing work and examine how key figures of merit for actuation at the microscale, including force output, response time, power consumption, efficiency, and durability are fundamentally intertwined. In doing so, we find performance limits and tradeoffs for different classes of microactuators based on the coupling mechanism between electrical energy, chemical energy, and mechanical work. These limits both point to future goals for actuator development and signal promising applications for these actuators in sophisticated electronically integrated microrobotic systems.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"1 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139917906","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}

Because of their presence in almost all environments known to humans, insects have inspired many small-scale flying, swimming, crawling, and jumping robots. This inspiration has affected all aspects of the robots’ design, ranging from gait specification, materials properties, and mechanism design to sensing, actuation, control, and collective behavior schemes. This article highlights how insects have inspired a new class of small and ultrafast robots and mechanisms. These new robots can circumvent motors’ force-velocity tradeoffs and achieve high-acceleration jumping, launching, and striking through latch-mediated spring-actuated (LaMSA) movement strategies. In the article, we apply a solution-driven bioinspired design framework to highlight the process for developing LaMSA-inspired robots and systems, starting with understanding the key biological themes, abstracting them to solution-neutral principles, and implementing such principles into engineered systems. Throughout the article, we emphasize the roles of modeling, fabrication, materials, and integration in developing bioinspired LaMSA systems and identify critical future enablers such as integrative design approaches.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":18828,"journal":{"name":"Mrs Bulletin","volume":"47 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139917851","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}

This approach has been instrumental in creating high-performance contacts for delicate lead halide perovskites, enabling quantum transport studies at low temperatures. Additionally, vdW integration has led to the development of vdW superlattices, and the chiral molecular intercalation superlattice offers a platform for exploring exotic chiral-induced spin selectivity effect and unconventional superconductivity. Together, vdW integration offers precise control over material composition and electronic structure, paving the way for innovative devices and the exploration of emergent quantum phenomena, all at the atomic scale.
