In this study, a core-shell composite Fe₃O₄@MnOOH (FMO) was synthesized, where Fe₃O₄ serves as the core and MnOOH acts as the shell. The EMW absorbing material exhibits unique characteristics of frequency bandwidth reversible conversion between high and low frequency. Through heat treatment, a chemical transformation occurs in the shell of FMO enabling the regulation of frequency bandwidth movement towards lower or higher frequencies, within a range from 3.5 GHz to 18 GHz. Upon subjecting FMO to heat treatment at temperatures of 400 °C, 550 °C, and 1000 °C respectively, MnOOH undergoes conversion into MnO₂, Mn₂O₃, and Mn₃O₄, achieving FMO400, FMO550 and FMO1000 composites correspondingly. Consequently, the frequency bandwidth shifts from 5.1 to 9.2 GHz for FMO to higher frequencies for FMO400 (8.4−13.6 GHz), FMO550 (12.3−18.0 GHz), and lower frequencies for FMO1000 (3.5−9.3 GHz). Additionally, reversible conversion is achieved through inter-conversion between FMO and FMO400 by converting MnOOH to MnO₂ via heat treatment while allowing reversible conversion enables regulation back to MnOOH through hydrothermal reduction of MnO₂. This reversible conversion enables regulation of the frequency bandwidth from 8.4 to 13.6 GHz for FMO400 to 5.2−9.6 GHz for FMO. Furthermore, due to the synergistic effect and excellent impedance matching of the core-shell structure, FMO exhibits a minimum reflection loss of −65.2 dB and an effective absorption bandwidth of 4.4 GHz. These properties demonstrate superior EMW absorption performance within the frequency range of 2–18 GHz. Due to the unique reversible conversion and bandwidth regulation characteristics of high and low frequency, it has great potential in 5G communication, aerospace, and military equipment applications.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"29 ","pages":"Article 100568"},"PeriodicalIF":8.2,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143175315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although most focus on finding approaches to address these two challenging issues of environmental stability and spatial dispersity, there has been no investigation of the impact of block copolymer (BCP) architectures on the performance of photomemory devices based on PVSK floating gates. Herein, this study explores carbohydrate-based BCPs to passivate the PVSKs. The dispersion of the CsPbBr₃ PVSKs is improved by a series of diblock and triblock BCPs comprising polydimethylsiloxane (PDMS) and maltoheptaose (MH). Benefitting from the strong hydrophobicity of PDMS blocks and strong hydrophilicity of sugar blocks, the resulting synthetic polymers form as high-<em>χ</em> BCPs, where <em>χ</em> is the Flory–Huggins interaction parameter. In addition, the wealthy hydroxy groups of sugar blocks interact with the PVSK precursors, which instantaneously control the crystallization growth by self-assembly microstructures. The PVSK/BCP nanocomposite films exhibit good optical performance, strong photoluminescence emission, a long exciton lifetime, an efficient charge transfer, excellent morphological topography, and optimal crystallinity of PVSK nanocrystal well-dispersed in the polymeric matrix. As an aspect of the application, the photomemory device based on the triblock BCP comprising PDMS and MH outperforms the diblock counterparts on long-term memory behavior, giving a high memory ratio &gt; 10⁴ over 10,000 s and high stability after 40 endurance cycles. In conclusion, the carbohydrate-based BCPs utilized as a floating-gate layer in photomemory with a photo-writing/electrical-erasing program show conspicuous data discrepancy, stable digital capacity, and decent switchability. The results indicate that the high-<em>χ</em> BCP architecture and polar group contents play an essential role in PVSK allocations, thereby boosting the photoresponse and stability in phototransistor memory.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"29 ","pages":"Article 100563"},"PeriodicalIF":8.2,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143176212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fabrication of free-standing PAA templates, several microns thick, as well as their applications, have been largely described in the literature. In recent years, research has focused on the synthesis of ultra-thin anodic alumina membranes (UTAMs), making them compatible with top-down fabrication and large-scale production. The ability to obtain these nanostructures on different surfaces, including glass, silicon wafers, or flexible substrates, extends their range of applications, enabling the integration of nanostructured materials on top of thin layers and allowing for the precise tuning of the physical and chemical properties of the materials. This review focuses on this new and promising nanopatterning approach to fabricate large areas of ordered nanostructures using UTAMs as patterning masks.
