One strategy to improve the piezoelectric/ferroelectric properties is to extend the solubility of Sc in wurtzite-type ScAlN. Herein, we demonstrated that introducing a lutetium (Lu) buffer layer with a hexagonal close-packed structure improved the crystallinity and <em>c</em>-axis orientation in wurtzite-type Sc<em>_x</em>Al_1-<em>_x</em>N thin films containing <em>x =</em> 0.508. The stabilization of the wurtzite phase was attributed to the epitaxial strain caused by the lattice matching between the Lu buffer layer and the ScAlN layer, resulting in an unprecedented piezoelectric constant of 35.5 pC/N, surpassing the previous 31.6 pC/N for <em>x =</em> 0.410. This value is an extension of the Sc concentration dependence predicted by first-principles calculations, suggesting that supersaturated Sc doping caused further elastic softening. Our results highlight interfacial engineering with lattice-compatible buffer layers as a straightforward and effective strategy to unlock the piezoelectric performance of ScAlN.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 85-95"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601807","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}

Herein, a template-confined microfluidic method that synergistically combines soft-imprinting and selected-location printing is reported for scalable printing of conformal electronics. This method allows precise printing of multiple materials and structures on large-area flexible/rigid and flat/curved substrates. The printed line width, confined by microarchitectural templates, reaches a high resolution of 300 nm. The microarchitecture topography is systematically investigated to optimize the wicking effects within the cross-scale templates. As a result, a phased-array antenna on a 1.25-meter-scale 3D surface can be fabricated in just 20 min due to the multi-directional parallel wicking occurring at multiple printing locations. Additionally, the printed circuits, embedded within and protected by the microarchitectural template, exhibit exceptional robustness by maintaining their initial resistance even after undergoing 600 cycles of an abrasion test. Furthermore, high-precise printing of commonly used functional nano-inks and graphics printing on arbitrarily curved substrates were also realized.

In this study, we propose a novel methodology that integrates electrophoretic assembly (electrophoretic deposition) and laser powder bed fusion additive manufacturing processes to create personalized, semipermeable, and biodegradable polymer/metal composite membranes suitable for guided bone regeneration applications. Specifically, we first designed a personalized porous Zn substrate using an adaptively unit-cell arrayed filling method, which achieved a complex and manufacturable curved surface shape while ensuring integrity of unit cells and uniform stress distribution. Subsequently, the Zn substrate was fabricated by laser powder bed fusion, and was utilized as both the bracing structure and the template for conformal electro-growth of chitosan/gelatin cryogel to obtain the desired polymer/metal composite membrane. This composite membrane allowed efficient nutrient transfer while inhibiting 100 % fibroblasts infiltration. As compared to Zn substate, coverage of conformal chitosan/gelatin cryogel enhanced mechanical properties and reduced the biodegradation rate of the membrane. Furthermore, the composite membrane exhibited remarkable osteogenesis and anti-infection capacity <em>in vitro</em>.

Additive manufacturing enables fast and easy fabrication of IMS devices from plastic. In recent works established drift time ion mobility spectrometers (DTIMS devices) were replicated using 3D printing technology by making use of functionalization through a conductive printing material. However, some electrical features such as the required resistance gradient were still set via conventional resistors. Therefore, new drift tube designs are presented with the intention of reducing the components and material used. For this purpose, three different drift tube types were fabricated, which were characterized and compared to a 3D printed drift tube with ring electrodes. Additionally, the analytical reproducibility was checked by comparing triplicates of the respective drift tube types. Cyclic olefine copolymer, which is particularly well suited for analytics due to its resistance to acids, alkalis and polar solvents, was used to manufacture the drift tubes. As a novel approach, a specially extruded coaxial filament is used, revolutionizing the manufacturing process of drift tubes in terms of effort, cost and time as the functionalization of the printed parts is already partly outsourced to the raw material.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 113-124"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mathematical model was developed to define the optimal parameters for the structure of a closed-cell matrix, maximizing its water-retaining and heat-absorbing capabilities. Specifically, we explicitly explained how the size of enclosed chambers varies with the changes in biopolymer molecular size and concentration, as well as freezable water content in the hydrogel. Moreover, scalable one-step chemical crosslinking processes were developed based on the optimized structure provided by the models, enabling controllable gelatin crosslinking in hydrogels to achieve the desired structural features. The JICs demonstrate significant promise for decarbonization efforts in many fields, especially by optimizing packaging efficiency in cold-chain logistics.
