Cellulose nanomaterials (CNMs) have emerged as bio-based feedstocks due to their exceptional strength and sustainability. However, challenges such as hornification and poor dispersion in polymer matrices still limit large-scale CNM–polymer composite manufacturing, requiring novel strategies. This review outlines an approach starting with atomic-level simulations to link molecular composition to key parameters like bulk density, viscosity, and modulus. These simulations provide data for finite element analysis (FEA), which informs large-scale experiments and reduces the need for extensive trials. The strategy explores how atomic interactions impact the morphology, adhesion, and mechanical properties of CNM-based composites in AM processes. The review also discusses current developments in AM, along with predictions of mechanical and thermal properties for structural applications, packaging, flexible electronics, and hydrogel scaffolds. By integrating experimental findings with molecular dynamics (MD) simulations and finite element modeling (FEM), valuable insights for material design, process optimization, and performance enhancement in CNM-based AM are provided to address ongoing challenges.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"25 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901751","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}

Generally, an ideal dynamic structural color platform requires full hue-saturation-brightness (HSB) control, high switching contrast, and a simple operation manner. Unfortunately, to date, it remains challenging to simultaneously achieve all these features using previous approaches. Here, a novel electrically and thermally switchable reflective nanoprinting platform is reported by integrating polarization-sensitive silver nanogroove arrays with a twisted nematic LC cell. Compared to conventional LC-assisted dynamic nanoprinting, the device can simultaneously achieve superior color purity, wider gamut, and higher switching contrast. Moreover, through the implementation of a sub-pixels scheme, arbitrary colors in the color gamut can be created by a mixture of red, green, and blue (RGB) channels at different ratios. As a proof of concept, dynamic switching of photorealistic nanoprinting with full HSB control at a high pixel density (>4,000 pixels per inch) as well as information switching and steganography are demonstrated, suggesting that the device possesses great potential in optical display and information security applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"95 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901750","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, atomically dispersed iron (Fe) and cobalt (Co) dual sites anchored N-doped graphene carbon (FeCoCN) catalyst is rationally constructed to achieve photothermally augmented catalytic oxidation for effective biocatalytic tumor nanotherapy. Compared with Fe SAzyme, FeCoCN SAzyme can significantly accelerate the charge transfer and improve the activity of catalytic reactions. Co-doping optimizes coordination structure and charge redistribution by facilitating the ratio of Fe2+ and regulating charge transfer between different metal sites and nearby coordination atoms. Bimetallic FeCoCN SAzyme possessed an ultra-high affinity for substrate H2O2, and the catalytic kinetic Km value (0.589 mm) is superior to natural catalase and most reported nanozymes. The boosted catalytic activity in producing •OH is identified by density functional theory (DFT) studies. In vivo, investigation demonstrates that atomically dispersed Fe and Co dual sites anchored FeCoCN SAzyme significantly suppresses tumor proliferation under NIR laser irradiation by photothermally enhanced catalytic oxidation. Additionally, Fe- and Co-doping in FeCoCN make it suitable as a tracer for T2 magnetic resonance imaging.

Herein, we develop an electron-dilution strategy by introducing Pd/Pt species into semiconductor ZnSe to construct electron-deficient Se surface, exhibiting excellent H2 sensing performances. It is found that different metal doping can induce remarkable electric environment changes of Se atoms. For example, compared with Pd, Pt display stronger electronic dilution ability to adjacent Se atoms. X-ray photoelectron spectroscopy (XPS) characterizations further prove that the doping of Pd/Pt will induce the generation of the electron-deficient Se sites, appearing a new and high binding energy state. Furthermore, the density functional theory (DFT) calculations show that the deficient Se sites on the Pt-ZnSe surface could reduce the level of anti-bonding orbital filling, thus enhancing the stability of the Se-Hads bond and strengthening the H2 adsorption. As a result, the Pt-ZnSe based micro-electromechanical systems (MEMS) gas sensors exhibit high response value of 3.22 to 10 ppm H2 at low operation temperature of 145 °C. Inserting the Pt-ZnSe MEMS sensors array into multifunctional wireless sensing device, it can realize real-time H2/temperature/humidity monitoring and cloud data transmission for hydrogen agriculture on production, preserving and storing crop.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"48 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901747","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}

However, the reactivity and stability of MOF are often impeded in catalytic reactions by structural collapse or phase transition stemming from commonly employed strategies such as defect engineering. The present work investigates a novel strategy for designing highly active Co₁Ni₁@UiO-66-NH₂ catalysts by embedding Co₁Ni₁ within the UiO-66-NH₂ framework. This approach facilitates efficient charge transfer between the reactants and the catalysts, thereby preserving both reactivity and structural integrity. The turnover frequency of Co1Ni1@UiO-66-NH2 is 430 h⁻¹, in contrast to 18 h⁻¹ of UiO-66-NH2, demonstrating that the transfer hydrogenation activity of Co1Ni1@UiO-66-NH2 is 24 times greater than that of UiO-66-NH2. More importantly, the reaction rate achieves 7.27 mol g⁻¹ h⁻¹, with a furfuryl alcohol (FOL) yield of 100%, and the Co₁Ni₁@UiO-66-NH₂ catalyst retains its excellent catalytic activity even after eight cycles of applications. Density functional theory calculations indicate that, in comparison to UiO-66-NH₂, Co- and Ni@UiO-66-NH₂, Co₁Ni₁@UiO-66-NH₂ exhibits relatively strong interactions and significant charge exchanges between reactants and catalysts. These interactions not only facilitate the dehydrogenation of isopropanol but also enhance the hydrogenation of furfural. Furthermore, the density of states reveals a greater number of states near the Fermi level in Co1Ni1@UiO-66-NH2 compared to Co- and Ni@UiO-66-NH2, and thereby facilitates the substantial charge exchanges and efficient catalytic performance of Co1Ni1@UiO-66-NH2.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"7 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901749","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}

Hydrogels as TENGs electrodes are common, but their use as direct triboelectric layers remains insufficiently explored. Here, a novel zwitterionic monomer 3-{1-[6-(hydroxymethyl)-2-methyl-3,8-dioxo-9-aza-4,7-dioxadodec-1-en-12-yl]imidazol-3-ium-3-yl}propane-1-sulfonate (VNIPS) is synthesized in combination with acrylic acid (AA) and zwitterionic sulfobetaine methacrylate (SBMA) to create a double-network zwitterionic hydrogel. The hydrogel is developed using a solvent-exchange process that facilitated the creation of microphase-separated domains, notablely increasing its mechanical strength (211.9 kPa, 472.3%), conductivity (0.6 mS cm−1), and anti-freezing capability (−18.3 °C). In addition, the hydrogel's hydrophilic groups interacted with water molecules, reducing charge loss in humid conditions. When employed as the triboelectric positive layer, the hydrogel-based TENGs achieved a substantial charge density of 456 µC m−2 and an output power density of 464 mW m−2, while maintaining a steady open-circuit voltage (Voc) of 97 V, with 92% retention under 80% relative humidity. Moreover, the hydrogel's strong adhesion and biocompatibility make it suitable for wearable applications, such as motion sensing and Morse code communication.

However, conventional IPDT faces challenges related to post-treatment safety, owing to the use of residual photosensitizers (PSs). In this study, on a novel H2O2-responsive aggregation-induced emission PS is reported, TBZPYBE, designed to selectively target cancer cells and enhance the therapeutic efficacy and postoperative safety of IPDT. Although TBZPYBE exhibits weak fluorescence, strong reactive oxygen species (ROS) are produced under light irradiation, demonstrating its high photodynamic therapy (PDT) efficacy in vitro and in vivo. Following PDT, TBZPYBE underwent self-quenching in the presence of H2O2, converting it to TBZPY, which exhibits strong fluorescence but reduced ROS generation. Simultaneously, quinone methide, a glutathione scavenger that amplifies PDT efficiency, is released. Furthermore, TBZPYBE activated the immune response by promoting dendritic cell maturation and polarizing M2 to M1 macrophages. The observed IPDT effects of TBZPYBE can be attributed to tumor selectivity, self-quenching mechanisms, and the ability to trigger immune responses, offering a balanced cancer treatment approach with improved post-treatment safety.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"70 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901871","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}

The TE figure of merit zT and, therefore, the device efficiency must be optimized by tuning the carrier concentration. However, electron concentrations in self-doped n-type Bi2SeO2 span several orders of magnitude, even in samples with the same nominal compositions. Such unsystematic variations in the electron concentration have a thermodynamic origin related to the variations in native defect concentrations. In this study, first-principles calculations are used to show that the selenium vacancy, which is the source of n-type conductivity in Bi2SeO2, varies by 1–2 orders of magnitude depending on the thermodynamic conditions. It is predicted that the electron concentration can be enhanced by synthesizing under more Se-poor conditions and/or at higher solid-state reaction temperatures (TSSR), which promote the formation of selenium vacancies without introducing extrinsic dopants. The computational predictions are validated through solid-state synthesis of Bi2SeO2. More than two orders of magnitude increase are observed in the electron concentration simply by adjusting the synthesis conditions. Additionally, a significant effect of grain boundary scattering on the electron mobility in Bi2SeO2 is revealed, which can also be controlled by adjusting TSSR. By simultaneously optimizing the electron concentration and mobility, a zT of ≈0.2 is achieved at 773 K for self-doped n-type Bi2SeO2. The study highlights the need for careful control of thermodynamic growth conditions and demonstrates TE performance improvement by varying synthesis parameters according to thermodynamic guidelines.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"41 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901864","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}
