Here, we report an interfacial self-assemblystrategy to fabricate large-area polyaniline (PANI) thin films featuringa hierarchically porous architecture and thickness-dependent porositygradient.

Here, combining first-principles calculations and Monte Carlo simulations, we identify monolayer CrGaTe3, derived from the Ga2S3 structure, as a ferromagnetic half-metal and a robust platform for hosting topological spin textures. The system exhibits a substantial Dzyaloshinskii−Moriya interaction (DMI) of 2.36 m V, arising from intrinsic inversion asymmetry and strong spin−orbit coupling, alongside sizable Kitaev exchange and magnetic anisotropy. At zero field, the ground state adopts a Néel-type cycloid state, which evolves into stable skyrmion phases under moderate external magnetic fields. Remarkably, beyond field tuning, we find that biaxial strain not only modulates the skyrmion size but also induces skyrmion states under tensile conditions, offering an additional degree of freedom for topological phase engineering. Furthermore, our parameter-resolved analysis reveals that while DMI is pivotal for skyrmion nucleation, the Kitaev interaction and magnetic anisotropy collectively govern the size and density of the skyrmion lattice. These findings establish monolayer CrGaTe3 as a promising candidate for sub-10 nm spintronic devices and demonstrate that the synergy between intrinsic symmetry breaking and external stimuli provides a generalizable strategy for designing functional 2D magnets.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"14 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374665","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}

Zn K-edge EXAFS gives Zn−O = 2.03 Å with a six-coordinate model in every state. The transformed phase has a smaller slow-process impedance and a larger initial utilization than crystalline controls, and DFT + U models of a reduced amorphous network with the same Zn content stabilize ionized Zn in O-rich disordered sites.

This investigation uses mixtures of well-known LiMn0.7Fe0.3PO4 (LMFP) and LiNi0.8Mn0.1Co0.1O2 (NMC) materials as a model blend system to investigate rate- and composition-dependent effects on performance. A combination of electrochemical and operando techniques reveals that deviations in performance with respect to the linear combination of the component materials originate from uneven current distribution, leading to different effective rates between components and spontaneous lithium-ion redistribution, commonly termed the “buffer effect”. Results of experiments using a specially adapted three-electrode setup show that the effective rates of the components vary considerably depending on the cell state of charge, with much higher effective rates being reached than the applied cell rate. The same setup allows the direction of lithium redistribution to be visualised when the system relaxes following a current pulse, and this directionality also varies with cell state of charge. Electrochemical investigations and Raman spectra reveal that blending reduces chemical sensitivity to ambient storage conditions and leads to reduced degradation by forming a protective LMFP layer around the more reactive NMC particles. Operando data shows that the blend components evolve largely as expected when taking into account their specific effective rates, in line with the materials retaining their individual electrochemical properties. This study highlights the importance of considering relative windows of electrochemical activity when selecting blend components and paves the way for future optimisation of electrode blends for high rate lithium-ion batteries.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"8 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368286","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}

Plasmon-assisted nanolithography has recently emerged as a powerful strategy to address this challenge by exploiting the highly confined electromagnetic fields and hot carriers generated during plasmon excitation to confine organic or inorganic layers at the nanoscale. Among the surface chemistries compatible with this approach, aryl diazonium salts are particularly attractive because their reduction produces highly reactive aryl radicals that form robust covalent bonds with metallic surfaces under mild conditions. Under light excitation, the plasmon-induced reduction of aryl diazonium salts enables the rapid and site-selective grafting of functional organic layers confined to plasmonic hot spots. The resulting functional films provide versatile chemical handles for further modification. However, to date, the use of plasmon-mediated diazonium grafting as a spatially controlled primer layer to direct the site-selective immobilization of colloidal nanoparticles remains unexplored. We address this gap by using lithographic gold nanodisc arrays as optically programmable templates. Under plasmon excitation, these nanostructures enable the formation of positively charged nanoscale anchoring domains at plasmonic hot spots, derived from diazonium salts bearing amine groups. These localized charged domains can then guide the spatial organization of negatively charged colloidal gold nanoparticles. The geometrical parameters of the plasmonic arrays, including nanodisc diameter and interparticle spacing, were carefully tuned to access different plasmon excitation regimes around the 633 nm laser wavelength, enabling blue-shifted, near-resonant, and red-shifted conditions, and expanding the variety of achievable hybrid patterns. Complementary characterization using SEM, UV−vis spectroscopy, and FDTD simulations demonstrates that this approach provides a straightforward and versatile strategy to direct the assembly of colloidal nanoparticles on lithographic nanostructures via optical excitation.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"29 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368213","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}

This Perspective evaluates compositional and structural descriptors by physical meaning, reference frame, covariance, and transferability. Pairwise cation mismatch contains the same information as size variance, whereas host-referenced misfit adds a reference-dependent mean-radius offset. Analysis of twenty-four published compositions from three systematic datasets illustrates the limits of configurational entropy and size variance as independent descriptors of phase formation and transport. With equal Hf, Zr, and Ce fractions, changing the host reference reverses misfit rankings and alters the host-offset term up to 78-fold. In twelve dual-phase zirconates and mixed zirconate-hafnates, the nominal rA/rB ratio correlates with phase fraction but describes neither coexisting phase, whereas measured phase compositions give non-overlapping fluorite and pyrochlore values, distinguishing descriptor limitations from inappropriate evaluation frames. Structural observables are assessed by specificity, reproducibility, and relevance. Together, these criteria and the compositional analysis define a framework that distinguishes compositional inputs, multiplicity and crystal-chemical mismatch, from their structural realization. Its purpose is to test descriptor relevance and limits rather than predict untested compositions.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"7 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2026-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149360582","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 report the synthesis and interfacial evolution of ZIF-8/ASO heterostructures and the in situ formation of metallic Ag nanoparticles (NPs) under electron irradiation. X-ray diffraction confirms the coexistence of cubic ZIF-8 (I43m) and monoclinic ASO (P21/c) phases, with a microstructure consisting of ZIF-8 NPs uniformly anchored on ASO microrods in intimate interfacial contact.

Photoluminescence measurements show pronounced emission quenching and spectral redistribution, indicating modified optoelectronic behavior following heterostructure formation. First-principles calculations identify the ZIF-8/ASO(010) interface as a favorable configuration, characterized by strong interfacial interaction and significant charge redistribution.
