Unlike conventional perovskite ferroelectrics, HfO2-based materials offer robust ferroelectricity at nanoscale thicknesses, large coercive fields (Ec), and innate compatibility with mainstream CMOS technology, thus overcoming long-standing integration challenges. This review comprehensively examines the development of HfO2-based ferroelectric field-effect transistors (HfO2-FeFETs) employing oxide semiconductor (OS) channels such as indium oxide (In2O3) and indium gallium zinc oxide (IGZO). We first discuss material-level optimizations via atomic layer deposition (ALD) processes, interfacial engineering, and capping layers to enhance ferroelectric performance and endurance. At the device level, we analyze the operational principles, unique challenges, including the weak erase effect due to the absence of hole carriers, and emerging solutions such as defect-assisted switching and novel gate-stack designs. We also highlight recent demonstrations of high-density 3D FeFET arrays and energy-efficient in-memory computing applications like ternary content-addressable memory (TCAM). Finally, we outline remaining challenges in scalability, variability, and switching linearity, pointing toward future research directions aimed at harnessing the full potential of OS-FeFETs for beyond-von Neumann computing architectures.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500353"},"PeriodicalIF":7.5,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147638007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many adsorbents materials were used in previous research but covalent organic frameworks (COFs) have shown significant potential. They are formed by chemically linking organic building blocks into a periodic framework, resulting in an ordered porous crystalline structure with high gas adsorption and retention capacity. COFs possess unique architecture, excellent crystallinity, high surface area, and high porosity which are the ideal condition for a good adsorbents. This review deeplyexplored the application of multidimensional (1-D, 2-D, and 3-D) COFs frameworks for CO2 adsorption.

The performance of TE systems is critically influenced by the synthesis techniques employed, which determine phase purity, compositional uniformity, microstructural features, and transport behavior. This review comprehensively analyses synthesis approaches across multiple material scales, bulk, nanostructured, and thin-film, highlighting how processing-structure-property correlations govern TE efficiency. Bulk synthesis routes such as arc melting, levitation melting, melt spinning, zone melting and self-propagating high-temperature synthesis (SHS) are discussed with emphasis on their control of grain growth, defect formation, and compositional homogeneity. Nanostructure-oriented methods, including high-energy ball milling, hydrothermal/solvothermal synthesis, coprecipitation, sol-gel processing, spark plasma sintering (SPS), and hot extrusion (HE), are evaluated for their ability to enhance phonon scattering and tailor carrier concentration through controlled grain refinement and defect engineering. Thin-film deposition techniques such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and wet-chemical methods are further reviewed for their precision in thickness control, crystallographic orientation, and interface stability, which are crucial for device-level integration. By linking processing strategies to TE performance, this review highlights hybrid synthesis, interface engineering, and eco-friendly materials as critical avenues for developing efficient and scalable TE technologies.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500299"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145833282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing efficient and cost-effective strategies to combat environmental pollution is of paramount importance. Metal-organic frameworks (MOFs) have recently emerged as a versatile photocatalytic platform, distinguished by their structurally tunable porosity, exceptional light-harvesting capacity, and superior charge separation efficiency. In particular, the intrinsically crystalline 3D structures of MOFs, characterized by highly ordered coordination networks and well-defined pore architectures, provide stable channels for molecular transport and endow the spatial organization of catalytically active sites. This review systematically summarizes the fundamental mechanisms and recent progress in MOF-based photocatalysis for environmental remediation, focusing on the degradation of organic pollutants, decomposition of antibiotics, and reduction of toxic heavy metal ions.

However, in complex matrices, nonspecific adsorption, ion competition, and background noise often compromise the accuracy and reliability of detection. In recent years, interfacial modification has provided effective solutions to these challenges. This review summarizes various interfacial engineering methods for solid-state nanochannels, focusing on three main aspects: stability enhancement, specific recognition, and signal amplification. For stability enhancement, strategies such as antifouling coating, surface charge/hydrophilicity regulation, and covalent crosslinking are highlighted. For specific recognition, structure-adaptive modification, biomimetic engineering, and cooperative self-assembly are discussed. For signal amplification, in situ nucleic acid amplification, nanotag-assisted amplification, and catalysis-mediated signal amplification are presented. Finally, current challenges and future perspectives are outlined, emphasizing that the integration of interfacial modification with multidisciplinary approaches, including nanomaterials, molecular engineering, and artificial intelligence-driven signal processing, which will further advance high-precision detection in complex matrices.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500264"},"PeriodicalIF":7.5,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146028582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
