The synthesis methods, structural categories, and multipurpose uses of carbon gels, such as aerogels, xerogels, cryogels, and hydrogels, are all well covered in this review. These materials are appropriate for a variety of applications due to their special qualities, which include high surface area, hierarchical porosity, electrical conductivity, and mechanical tunability. Recent developments in green synthesis techniques employing precursors generated from biomass are highlighted, including the creation of hybrid systems that combine metal oxides, graphene, and carbon nanotubes to improve mechanical strength, conductivity, and catalytic activity. A critical analysis of how different drying and carbonization methods affect pore structure, stability, and performance is conducted. Carbon gels' uses in fuel cells, lithium-ion/sodium-ion batteries, supercapacitors, and water treatment are discussed, with an emphasis on how their structural characteristics affect their adsorption and electrochemical properties. The analysis also examines the increasing interest in hydrogels based on graphene and gels made from biomass as environmentally friendly and sustainable substitutes for energy systems. Despite impressive advancements, problems with mechanical robustness, pore structure management, and cost-effective large-scale production still exist. In order to create next-generation carbon gel materials for worldwide energy and environmental solutions, future prospects are examined with a focus on combining green chemistry, functionalization methods, and innovative composite designs.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 20","pages":" 7153-7206"},"PeriodicalIF":4.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00786k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of the magnet caused the rutile TiO2 nanoparticles to self-assemble into a branching, hierarchical particle agglomerate structure, with a large surface area comprising various pore sizes. These structural features appear to be due to ferromagnetism induced by surface oxygen vacancies in anatase and rutile TiO2, or to electrostatic charging effects. The resulting chain-like structures present themselves as a film 10 micrometers in thickness. As observed by helium ion microscopy, and scanning as well as transmission electron microscopy, this structure is highly porous featuring remarkably high specific surface areas, quantified as 650 m2 g−1 by BET nitrogen absorption measurement. The elemental composition, chemical bonding, and purity of the collected rutile TiO2 nanoparticles were analyzed by TOF-ERDA, XAS, and TEM EDS, as well as FTIR, UV-Vis, and Raman spectroscopies, confirming the prevalence of the rutile phase. This highly porous and easily accessible structure was able to photocatalytically degrade dyes at rates compatible with the typical photocatalytic performance of rutile TiO2. We believe that upon further development, this synthesis technique holds great potential for the selective synthesis of high-purity few-nanometer-sized rutile without the need for high temperatures, providing a facile fabrication route for a reference model system in photocatalytic conversion reactions.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 19","pages":" 6764-6774"},"PeriodicalIF":4.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00186b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The voids are nearly eliminated by annealing between 1120 °C and 1160 °C under Ar which also leads to grain growth. However, the out diffusion of the voids through the single crystal Cu2O grains is accompanied by the formation of holes at the surface. We show that the layer of voids can be removed by polishing the Cu2O down to ∼10 μm in order to preserve the single crystal nature of the grains obtained at 1020 °C while keeping the thermal budget to a minimum and discuss the limitations in exploiting the Cu2O obtained in this way for the fabrication of devices.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 19","pages":" 6868-6876"},"PeriodicalIF":4.7,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00642b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces the development of an innovative non-enzymatic electrochemical biosensor designed for the sensitive detection of creatinine. The biosensor was created by functionalizing carbon nanotubes with anhydrous copper acetate through a simple one-step hydrothermal method. The unique properties of carbon nanotubes provide numerous adsorption sites that promote specific coordination interactions between copper nanoparticles and creatinine, thereby establishing the foundation for the sensor's enhanced sensitivity. The sensor exhibits remarkable specificity, with the creatinine concentration demonstrating a linear response within the range of 0.01 mM to 1 mM, and an exceptional sensitivity of 8617.86 μA mM−1 cm−2. Notably, superior sensors of this type have been documented, particularly within the narrower concentration range of 0.01 mM to 0.05 mM, indicating that this sensor outperforms others in its class. Furthermore, density functional theory (DFT) calculations, encompassing electron state density, differential charge density, and adsorption energy assessments, corroborate the material's outstanding properties and elucidate the underlying detection mechanism. Furthermore, a range of flexible creatinine sensors was developed utilizing 3D printing and sputtering techniques. These sensors demonstrated exceptional sensing performance, thereby expanding the potential applications of the material and effectively highlighting its intrinsic properties.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 20","pages":" 7494-7504"},"PeriodicalIF":4.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00644a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces an open-source computational framework—GRATEv2 (GRaph-based Analysis of TEM, Version 2)—designed for near-real-time analysis of semi-crystalline, polymeric microstructures; its capabilities are illustrated on poly[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT), a benchmark material in organic photovoltaics. GRATEv2 employs fast, automated image processing algorithms, enabling rapid extraction of structural features like d-spacing, orientation, and crystal shape metrics. Bayesian optimization rapidly identifies the parameters (that are traditionally user-defined) in the approach, reducing the need for manual parameter tuning and thus enhancing reproducibility and usability. Additionally, GRATEv2 is compatible with high-performance computing (HPC) environments, allowing for efficient, large-scale data processing at near real-time speeds. A unique feature of GRATEv2 is a Wasserstein distance-based stopping criterion, which optimizes data collection by determining when further sampling no longer adds statistically significant information. This capability optimizes the amount of time the TEM facility is used while ensuring data adequacy for in-depth analysis. Open-source and tested on a substantial PCDTBT dataset, this tool offers a powerful, robust, and accessible solution for high-throughput material characterization in organic electronics.","PeriodicalId":18242,"journal":{"name":"Materials Advances","volume":" 19","pages":" 6820-6842"},"PeriodicalIF":4.7,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ma/d5ma00409h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, very limited literature is available on the development of UD jute fibre-reinforced composites from biodegradable matrices such as polylactic acid (PLA). This work presents the development of highly compressed UD jute fibre preforms and composites from a PLA matrix. The results support the fact that compared to the mechanical properties of neat PLA, those of the composites improve significantly with an increase in the fibre content. At 50% fibre content, the composite achieved the highest tension strength of about ∼187 MPa and flexural strength of approximately ∼91.77 MPa.

The proposed architecture of PW materials can effectively suppress irreversible phase transitions at high operating voltages by stabilizing the lattice structure and hindering the formation of undesirable phases, thus improving battery performance.
