{"title":"Effect of Methylcellulose Chain Design on Gelation and Fibril Structure Using Coarse-Grained Modeling","authors":"Stephen Kronenberger, Arthi Jayaraman","doi":"10.1021/acs.chemmater.5c00862","DOIUrl":"https://doi.org/10.1021/acs.chemmater.5c00862","url":null,"abstract":"Aqueous solutions of methylcellulose (MC) undergo thermoreversible gelation making them useful as additives for formulations with desired rheological properties. This gelation occurs at elevated temperatures and concurrently with the formation of stiff, high aspect ratio fibrils composed of several MC chains. The sol–gel transition temperature as well as the fibrillar structure of the gel state can be controlled by the molecular weight of the MC chains, MC concentration, and the design of the MC chains. One such MC design parameter is the degree of substitution (DS) which varies between 0 (cellulose) to 3.0 (fully methylated cellulose chain). The DS of commercially available MC (e.g., International Flavors and Fragrances’ Methocel A) is ∼1.8. The DS as well as the pattern of methylation (i.e., homogeneous or heterogeneous substitution) along the MC backbone can be tailored using variations in the synthesis protocols. To elucidate the effect of these MC chain design parameters on the sol–gel transition and the fibrillar structure of the MC chains, we conducted a multiscale computational study. First, we developed a coarse-grained (CG) model for MC with the model’s bonded parameters informed from atomistic simulations using Boltzmann inversion and nonbonded parameters informed from previous experimental studies of aqueous MC sol–gel phase behavior using surrogate Bayesian optimization. We performed molecular dynamics (MD) simulations of aqueous MC solutions with this CG model and characterized the effect of DS and methylation pattern on the gelation temperature and the MC chains’ fibril structure, specifically fibril diameter and persistence length. Fibril diameters and persistence lengths in our simulated systems agree well with those found from previous small-angle scattering analysis and electron microscopy measurements, providing validation for the results from the CG MD simulations. Using these CG MD simulations, we span a large MC design parameter space and identify these key design rules: (i) Aqueous solutions with MC chains having larger heterogeneity in the DS along the chain backbone, will gel at lower temperatures and assemble into fibrils with a smaller diameter. (ii) As the DS becomes “blockier” along the MC backbone, gelation will occur at lower temperatures, and fibril diameters will decrease. We expect our model development and the above design rules will aid future work focused on synthesis and/or simulation of MC with tailored gel properties for desired applications.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"9 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340880","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}

These side-chains can strongly influence the repeat unit symmetry, polarity, steric bulk, and noncovalent interactions that collectively dictate how polymer chains pack and assemble. Acyclic dioxythiophene polymers (PAcDOTs) are highly redox-active thiophene-based organic mixed ionic-electronic conductors (OMIECs) where both the 3- and 4-positions of the thiophene ring are substituted by alkoxy groups. In this study, we explore the solution and solid-state structures of both symmetric (R1 = R2) and asymmetric (R1 ≠ R2) PAcDOTs, where R1 and R2 are both either nonpolar or amphiphilic, and we observe rich process-structure behavior. The combination of regio-symmetric and amphiphilic side-chains results in a chiral, lyotropic phase in chloroform solutions that persists as a metastable state in thin films. Temperature-dependent grazing incidence X-ray scattering and cross-polarized optical microscopy indicate that PAcDOTs with regio-symmetric linear side-chains can crystallize into highly ordered morphologies upon thermal treatment. Finally, we show that side-chain polarity, symmetry, and thermal annealing affect the electrochemical doping and dedoping processes.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"51 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335083","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}

Among them, metastable-phase 2D transition metal nitrides (Meta-2D TMNs), structural analogues of MXenes, exhibit significant potential for electrochemical energy conversion due to their noble-metal-like electronic configurations and excellent electrical conductivity. However, the scalable synthesis and performance optimization of Meta-2D TMNs remain challenging. These challenges primarily stem from the instability of high-energy 2D structures during formation and competing side reactions, such as the decomposition of ammonia precursors that promote nitrogen triple-bond formation at elevated temperatures. This review systematically evaluates the emerging synthetic strategies and design principles for developing high-performance Meta-2D TMN-based electrocatalysts. Key topics include formation mechanisms, thermodynamic and kinetic barriers, and approaches to lower formation energy while suppressing undesirable side reactions. Particular emphasis is placed on the role of structural and compositional engineering in tuning electrocatalytic performance, thereby advancing the understanding of structure–property relationships in metastable systems. By highlighting advances in controlled synthesis, fundamental structure–property correlation, and the exploration of metastable compounds, this review provides insights into the rational design of Meta-2D TMNs and their potential applications in sustainable energy conversion and storage technologies.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"146 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144329195","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}

Through nanosizing, solid solution formation can be achieved even for immiscible elements, but conventional synthesis of such alloy nanoparticles (ANPs) often requires harsh conditions, such as high temperature, pressure, and organic solvents. Therefore, developing simpler, low-temperature, liquid-phase synthesis methods is highly desirable. However, reactant diffusion during insufficient mixing of precursor solutions hinders uniform nucleation and composition control. In this study, we synthesized Pd–Ru ANPs in an aqueous solution at room temperature using a microreactor with excellent mixing performance, which created a uniform reaction field. This technique allowed the simultaneous reduction of different ions before nucleation, enabling precise composition control. The resulting Pd–Ru ANPs exhibited uniform size and composition, and their catalytic properties showed enhanced activity compared to monometallic nanoparticles, as evaluated via carbon monoxide (CO) oxidation rate measurements. Notably, under room-temperature conditions, increasing Ru content resulted in a reduced crystallinity and induced localized structural disorder. This unique structural feature enabled optimal CO oxidation activity at a lower Pd composition than that reported previously. This method provides a simple and effective approach for the synthesis of ANPs with controlled compositions under mild conditions.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"16 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144329136","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}

We demonstrate that the formation of intermetallic compounds or multimetallic metal oxides can further extend the aqueous stability window of a given metal species, even if the corresponding pure metal or metal oxides are inherently unstable within water. Such stabilizing effect arose from thermodynamic principles, as multimetallic, intermetallic, or metal oxide ground states need to show negative formation energy in the convex hull made from the single metal counterparts, e.g., pure metal or binary oxides. This synergy between different metals provides a valuable framework for guiding the compositional design of corrosion resistance for multimetallic systems.

Despite the promising attributes of GeTe as a midtemperature p-type thermoelectric material, its practical efficiency remains constrained by inherent challenges, namely, its high lattice thermal conductivity and suboptimal carrier concentration. In this study, we introduce an innovative dual-strategy framework that seamlessly integrates tailored alloying and band convergence to achieve a profound decoupling of electrical and thermal transport properties in GeTe. Through systematic investigations of Se and Pb alloying, we demonstrate that Se alloying effectively reduces lattice thermal conductivity by enhancing phonon scattering, while maintaining superior carrier mobility─outperforming Pb alloying in this regard. Moreover, the strategic incorporation of Sb doping at Ge sites not only refines carrier concentration to optimal levels but also enhances crystal symmetry, thereby fostering valence band convergence and significantly elevating the Seebeck coefficient─a critical metric for thermoelectric performance. The synergistic implementation of these advanced strategies culminates in the optimized composition Ge_0.9Sb_0.1Te_0.9Se_0.1, which attains a remarkable peak ZT value of approximately 1.8 at 773 K and maintains an impressive average ZT of 1.1 across the temperature range 300–773 K.

The trimethylammonium headgroup is bulky, and the unique chemical shifts of its protons allow for systematic studies of ligand density and dynamics as a function of both nanoparticle size and ligand length for fully saturated surfaces. Chemical shift analysis of the solvent-exposed headgroup protons supports the notion that ligand headgroups pack closer together as the AuNP diameter increases for all ligands. Quantitative analysis shows that ligand density for the shorter ligands (MUTAB (<i>X</i> = 11) and MTAB (<i>X</i> = 16)) is dependent on nanoparticle size, ranging from ∼10 to ∼2 molecules/nm² as the nanoparticle size increases, while ligand density is independent of size (∼2 molecules/nm²) for longer ligands (MOTAB (<i>X</i> = 18) and MITAB (<i>X</i> = 20)). <i>T</i>₂ relaxation analysis shows less headgroup motion and therefore more ordering as both the NP diameter and the chain length increase. Gold etching experiments with potassium cyanide were performed to determine the ability of ions to penetrate the ligand layers; core protection and headgroup motion, as judged by <i>T</i>₂, were negatively correlated for the two shorter ligands but not correlated with the two longer ligands. Molecular dynamics simulations indicated that the longer ligands have a stronger tendency to form ligand islands on curved surfaces due to increased van der Waals interactions between the alkane portions of ligands, suggesting that the presence of patchy ligand islands displays hydrophobic character that prevents the cyanide ion from penetrating the AuNP cores. The relationship between ligand length and nanoparticle diameter/curvature leads to rudimentary predictions of ligand dynamics.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"46 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319915","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}

However, it remains a significant challenge for the electrocatalysis community, requiring an urgent demand for developing highly selective electrocatalysts for H₂O₂ generation. Herein, a cost-effective and nonprecious perovskite oxide composite material, BiFeO₃/g-C₃N₄ (BFO_gCN), has been successfully synthesized as an electrocatalyst for the 2e^– ORR through a simple physical mixing, followed by calcination, demonstrating its exceptional selectivity for H₂O₂ generation. The synthesis technique allows for altering the electronic structure of BiFeO₃ (BFO) and g-C₃N₄ (gCN), ensuring a high oxygen vacancy, increased hydroxyl adsorption on the surface of the BFO_gCN composite, and conductive gCN sheets that facilitate the ORR. The composite catalyst (50_BFO_gCN) exhibits high H₂O₂ selectivity, exceeding 70% throughout a broad potential range of 0.3–0.6 V versus RHE, compared to other composites for the ORR in an alkaline medium. The H₂O₂ selectivity of the synthesized electrocatalyst is consistently sustained for 50 h at 0.5 V during a durability assessment. The yield rate of H₂O₂ reaches a maximum of 1528.8 mmol g^–1 h^–1 at 0.5 V, exhibiting a faradaic efficiency (FE) of 94.9% after 3 h of electrocatalysis. To assist the experimental observation, the Perdew–Burke–Ernzerhof (PBE) functional with the Grimme’s third-order (-D3) dispersion corrections (in short PBE-D method) has been employed to explore the ORR mechanism. These calculations reveal that the improved performance of the subject material is due to the oxygen vacancy at the Fe site, and it also stabilizes the critical intermediates, such as OOH*, thereby preventing O–O bond breaking and suppressing the 4e^– pathway. This study introduces a highly selective electrocatalyst for the 2e^– ORR and offers an approach to electrocatalyst design.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"11 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305196","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}
