Sericin Electrodes with Self-Adhesive Properties for Biosignaling The combination of green manufacturing approaches and bioinspired materials is growingly emerging in different scenarios, in particular in medicine, where widespread medical devices (MDs) as commercial electrodes for electrophysiology strongly increase the accumulation of solid waste after use. Electrocardiogram (ECG) electrodes exploit electrolytic gels to allow the high-quality recording of heart signals. Beyond their nonrecyclability/nonrecoverability, gel drying also affects the signal quality upon prolonged monitoring of biopotentials. Moreover, gel composition often causes skin reactions. This study aims to address the above limitation by presenting a composite based on the combination of silk sericin (SS) as a structural material, poly(vinyl alcohol) (PVA) as a robustness enhancer, and CaCl<sub>2</sub> as a plasticizer. SS/PVA/CaCl<sub>2</sub> formulations, optimized in terms of weight content (wt %) of single constituents, result in a biocompatible, biodegradable "green" material (free from potentially irritating cross-linking agents) that is, above all, self-adhesive on skin. The best formulation, i.e., SS(4 wt %)/PVA(4 wt %)/CaCl<sub>2</sub>(20 wt %), in terms of long-lasting skin adhesion (favored by calcium-ion coordination in the presence of environmental/skin humidity) and time-stability of electrode impedance, is used to assemble ECG electrodes showing quality trace recording over longer time scales (up to 6 h) than commercial electrodes. ECG recording is performed using customized electronics coupled to an app for data visualization.

Giant spin Seebeck effect in two-dimensional V<sub>2</sub>S<sub>2</sub>O altermagnet Altermagnet is an uncommon category of antiferromagnets distinguished by their non-overlapping spin-bands, drawing significant attention from researchers. However, while reports on their electronic and magnetic properties are increasing rapidly, the study on the transport properties is still in early stage. Therefore, we explored the orientational spin-dependent transport features of altermagnet V2S2O using Boltzmann transport technique. This altermagnet had 1.15 eV direct band gap energy and a critical temperature of 746 K. We obtained a directional spin-dependent feature in the band structure whose effect spans through all the spin-dependent transport parameters. We found a low isotropic lattice thermal conductivity of magnitude 0.2 Wm-1K-1 at 300 K. Above all, the V2S2O altermagnet displayed a giant spin-dependent Seebeck coefficient of about 1.8 mVK-1 at 300 K and at a small electron or hole doping. This value is multiple times greater than reported values for most transport materials. Besides, we also found a maximum figure of merit of 0.86 in the hole-doped systems. Thus, our findings suggest the possibility of pure spin current generation for possible applications in spintronics and thermoelectricity.

Laboratory-based X-ray diffractometer with fast time resolution for <i>operando</i> battery studies O<i>perando</i> X-ray diffraction (XRD) is an important characterization tool for real-time monitoring of structural changes in materials under different reaction conditions. In this study, we developed a laboratory-based diffractometer that could capture a full XRD spectrum within 10 s. The instrument has several advanced features. First, it uses a Ga–In alloy metal-jet X-ray source, thereby achieving high X-ray flux with a brightness of up to 3.0 × 10<sup>10</sup> photons/(s·mm<sup>2</sup>·mrad<sup>2</sup>). Second, it employs an ellipsoidal mirror with a multilayer coating to produce quasi-parallel monochromatic light characterized by a divergence of 0.6 mrad and an energy resolution of 5.9 × 10<sup>−3</sup>. Third, it is equipped with a high-efficiency, high-signal-to-noise-ratio Pilatus 3R 1M detector for collecting diffraction signals. These features make the developed instrument applicable in studying rapid phase transitions in lithium-ion batteries, especially under extremely fast charge–discharge conditions. The data quality was comparable to that of synchrotron radiation XRD.

Large Language Models (LLMs) as Graphing Tools for Advanced Chemistry Education and Research Large language models (LLMs) are positioned to transform how students interact with data in classroom and laboratory settings, both now and in the future. The integration of LLMs into chemical curricula, if done effectively, may improve student equity and learning outcomes and provide an alternative approach to data analysis alongside traditional methods. One of the key strengths of LLMs is their ability to efficiently summarize large data sets and transform them into understandable forms. Although the ability of LLMs to help students process qualitative data is well established, here we focus on use of LLMs to process quantitative data and, specifically, make high-quality data plots without relying exclusively on spreadsheet skills. Specifically, we tested the ability of OpenAI’s ChatGPT to plot Walsh diagrams relevant to an ongoing laboratory experiment conducted in an undergraduate inorganic chemistry course. It was found that the LLM could generate high-quality graphs from raw data with appropriate prompts. Furthermore, the LLM was able to parse long computational output files to extract relevant data as well as perform multivariate linear regression. A pilot experiment integrating LLMs as a tool to generate graphs from complex data sets into a 300-level inorganic chemistry laboratory showed that ∼60% of the students considered LLMs as an efficient tool for data analysis, ∼40% felt the tool significantly enhanced their learning, and ∼5% experienced frustration. Introducing LLMs as a supplementary tool for data processing could help students who struggle with spreadsheet software without replacing essential spreadsheet skills that are fundamental to training the STEM workforce. Implementation of LLMs as a data processing tool may bring about equitable outcomes in quantitative chemistry courses regardless of students’ prior experience with spreadsheet software.

Discreteness and dispersity in the design of polymeric materials Nature produces macromolecules with discrete molar mass and precise composition, both of which are essential for ensuring structural control, distinctive properties, and specific functions. However, in some cases, bioderived components are heterogeneous in size, and this plays a crucial role in defining their physicochemical characteristics. In a similar way, polymer scientists have been striving to develop robust synthetic protocols to access macromolecules with homogeneous composition and discrete molar mass. Simultaneously, significant advances in controlled polymerization techniques have enabled the precise regulation of chain length heterogeneity, or dispersity ( Đ ), across a wide range of values. Achieving perfectly monodisperse polymers is not only a remarkable synthetic achievement but also provides fundamental building blocks for new classes of polymeric materials. These materials could be either free of defects or exhibit properties that are precisely tunable in a quantized manner. On the other hand, obtaining polymer samples with controlled dispersity provides an additional tuning parameter for the physicochemical properties of a variety of materials formulations. By leveraging macromolecular discreteness and fine-tuning polymer dispersity, we have expanded the toolbox for designing advanced “soft” materials. Block copolymers with discrete segment lengths or controlled dispersity can be used to create novel nanostructured materials. Stimuli-responsive polymeric systems can be engineered to precisely adjust their physical transitions while maintaining a constant chemical composition. In addition, tailoring polymer dispersity during the fabrication of gels and brush coatings enhances the ability to fine-tune their physicochemical properties, further broadening their potential applications.

Triethylamine-mediated protonation–deprotonation unlocks dual-drug self assembly to suppress breast cancer progression and metastasis Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism. Specifically, TEA facilitated the deprotonation of Doxorubicin (Dox) and α-Tocopherol succinate (α-tos), causing Dox to transition from a hydrophilic to a hydrophobic state, while simultaneously increasing the hydrophilicity of α-tos. This allowed for a fine-tuned balance between the hydrophilic and hydrophobic properties of the two compounds, enabling their precise self assembly into a carrier-free nanomedicine (DT) with a tailored drug ratio. The engineered DT demonstrated the ability to accumulate at the tumor sites and release its therapeutic drugs in a controlled manner. The combination of Dox and α-tos synergistically generated reactive oxygen species and modulated the expression of tumor matrix metalloproteinase-9, leading to superior antitumor efficacy without significant metastasis, while maintaining excellent safety profiles. Our findings provided unique perspectives on the design of carrier-free nanomedicine for cancer therapy, thereby laying a solid foundation for its potential clinical translation.

Competing Self‐Assembly to Access Helical Chitin Nanofibers for Advanced Chitinous Materials Abstract Self‐assembly affords a rich design space in fabricating polymeric nanomaterials. However, the crystalline polymer often exhibits the vigorous self‐assembly process due to the extensive inter‐ and intra‐molecular interactions, leading to the challenge in controlling their self‐assembly behavior at the nanoscale. Herein, this work proposes a competing self‐assembly strategy to regulate the molecular self‐assembly tendency of chitin (a semi‐crystalline polysaccharide) for achieving the regenerated chitin nanofibers with helical structure. This approach focuses on subtly modulating the noncovalent interactions among the chitin chains through deacetylation in a homogeneous system. By fine‐tuning the degree of deacetylation (DD) to a moderate level (≈26%–37%), this work facilitates the chitin chains to compete self‐assembling into the α‐chitin and hydrated chitosan crystalline structure, which effectively mitigates the overall self‐assembly tendency of the chitin chains and ultimately restricting their aggregations to nanoscale dimensions. This fabrication concept achieves various chitin nanofibers morphology (single, randomly branched and comb‐like), all featuring a helical configuration. The chitin nanofibers are successfully processed into the nanopaper and bioink, highlighting the potential in constructing high‐performance materials. This work anticipates that the competing self‐assembly concept can be extended to other crystalline polymers with strong molecular interactions, offering a new pathway to design advanced nanomaterials for diverse applications.

3D-Printable Biobased Eutectogels Based on Soybean Oil and Natural Deep Eutectic Solvents for Underwater EMG Recording Hydrophobic eutectogels represent an emerging class of soft materials with significant potential to revolutionize underwater body signal recording and sensing technologies. Existing materials, however, are limited by poor performance or low biocompatibility. To address these challenges, herein, we propose a biobased eutectogel that combines hydrophilic and biocompatible deep eutectic solvents (DES) with a nontoxic and highly hydrophobic polymer matrix based on acrylated epoxidized soybean oil (AESO). We demonstrate fine-tuning of electrochemical, rheological, mechanical, and water-repelling properties by varying the degree of AESO functionalization and their DES composition and content. The resulting formulations demonstrated excellent suitability as inks for VAT photopolymerization three-dimensional (3D) printing, enabling the fabrication of structured hydrophobic gel electrodes. Underwater electromyography (EMG) recordings highlight the potential of these materials for use in marine biology, exploration, and environmental monitoring applications.

Nitrogen Insertion via Asymmetric Condensation and Chirality Transfer: A Stereodivergent Entry to Cyanocyclopropanes The condensation of prochiral cyclobutanones and diphenylphosphinyl hydroxylamine is achieved under Brønsted acid catalysis. Interestingly, the competing aza-Baeyer-Villiger reaction is completely suppressed and the axially chiral oxime esters can be isolated in excellent yield and selectivity (up to 96% yield, up to 97:3 er). Computational analysis highlights the crucial role of the Brønsted acid in facilitating a successful condensation. Building on the inherent reactivity of the corresponding oxime esters, a one-pot protocol toward cyanocyclopropanes was discovered, which establishes two consecutive stereocenters. This unusual ring contraction is triggered by strong base and permits an axial-to-point chirality transfer with good enantiospecificity (up to 98% es). Fine-tuning the reaction parameters enables stereodivergent access to both diastereomers of the cyanocyclopropanes, and the utility of this method is demonstrated through the formal synthesis of the drug tasimelteon.

Pd Ensemble Sites Tuned Local Environment of Cu Catalysts for Matching Propyne Semi‐Hydrogenation Abstract Tailoring local environments of active sites to match targeted configuration of key species is significant for controlling reaction pathways in selective hydrogenations. Herein, differently typed Pd sites are introduced onto Cu catalysts to tune the local environment of Cu sites for controlling the configuration of semi‐hydrogenation pathway of propyne hydrogenation used in production of polymer‐grade propylene. Detailed structure characterizations demonstrate the controllable construction of Pd single‐atom and Pd ensemble sites modified Cu surfaces and PdCu alloy via fine tuning the Pd/Cu ratios. Catalytic tests, kinetics analysis, and temperature‐programmed experiments demonstrate that the presence of Pd ensemble sites on Cu surface directly catalyzes the hydrogenation of propyne that occurs on the Cu sites in other cases, and enables a facile activation for hydrogen and simultaneously promotes the desorption of propylene against its hydrogenation. Accordingly, the selectivity to target propylene is up to 95.3% at the full conversion of propyne on the corresponding Pd 0.1 Cu catalyst. In contrast, the C─C coupling pathway is quite facile on the Cu surface tuned by single‐atom Pd sites, which is similar to that on the pristine Cu sites on the Cu catalyst, and the well‐defined Pd─Cu coordination on PdCu alloy catalyst leads to facile over‐hydrogenation process.
