Electrospun Fibers of Polyhydroxyalkanoate/Bacterial Cellulose Blends and Their Role in Nerve Tissue Engineering Abstract Multimaterial blends are crucial for developing scaffolds for tissue engineering. In this study, novel blend electrospun nanofibers are created by combining short‐chain length polyhydroxyalkanoates (SCL‐PHAs), medium‐chain length polyhydroxyalkanoates (MCL‐PHAs), and bacterial cellulose (BC) using the electrospinning technique. The resulting fibrous materials are characterized for their thermal properties, morphology, and cytocompatibility with NG108‐15 neuronal cells. The fabricated blend nanofibers demonstrate good cytocompatibility, as indicated by trends in cell viability and neurite outgrowth in NG108‐15 cells. Importantly, the inclusion of BC in the blend significantly improves the thermal stability of the polymer matrix, as confirmed by thermogravimetric analysis. This study introduces the concept of environmentally friendly and multifunctional materials, highlighting their potential for diverse applications in various scientific disciplines and industries, particularly in the field of nerve tissue engineering.

Adaptive Co‐Crystals with Switchable Host‐Guest Stoichiometry for Dynamic Regulation of Photoluminescence The development of photoluminescence materials with tunable properties through structural and functional modifications remains a fascinating yet challenging task. In this work, the concept of adaptive co-crystals featuring switchable host-guest stoichiometry within the realm of pillararene-based supramolecular chemistry is proposed. This strategy allows for the rational design of a diverse range of through-space charge-transfer co-crystals, enabling dynamic modulation of photoluminescence in the solid state. Experimental and theoretical findings unveil two distinct phases within each set of co-crystal architectures, characterized by different donor/acceptor stoichiometric ratios as well as molecular packing modes. Notably, these co-crystalline phases undergo vapor-induced stoichiometry switching and structural interconversion, resulting in unique charge-transfer transition states and enabling reversible control over photoluminescent behavior. Particularly, this dynamic modulation of the cavity apertures, driven by stoichiometric variation, facilitates highly selective capture and release of 1-bromoalkane under mild conditions. The present study highlights the potential application of vapor-mediated co-crystals with switchable stoichiometry as a supramolecular strategy for modulating the intrinsic characteristics of intermolecular donor-acceptor materials.

Unveiling the complex morphologies of sessile droplets on heterogeneous surfaces Abstract Droplets exhibiting a myriad of shapes on surfaces are ubiquitous in both nature and industrial applications. In high-resolution manufacturing processes, e.g., semiconductor chips, precise control over wetting shapes is crucial for production accuracy. Despite the high demand for describing droplet wetting shapes and their transformations across a wide range of applications, a robust model for precisely depicting complex three-dimensional (3D) wetting droplet shapes on heterogeneous surfaces remains elusive. Herein, we fill this gap by developing a universal, high-precision model that accurately describes wetting shapes, including those with polygonal baselines and irregular footprints. Our model reveals the intricate wetting morphologies beyond the classic Young’s law and Cassie-Baxter-Wenzel models. Besides, it aligns quantitatively with physical simulations for various droplet volumes. This work provides a potential method to achieve highly complex morphologies of droplets via low-cost beforehand design of the surfaces, thereby opening up potential applications in 3D printing, printed electronics, and microfluidics.

High‐Security and High‐Efficiency Information Encryption/Decryption Based on 2D Hybrid Organic–Inorganic Perovskites via Delicate Organic‐Cation Engineering Optical encryption based on stimuli-responsive luminescence (SRL) materials has received enormous interest in the field of information security. Metal-halide perovskites, as a newly emerging SRL material, have shown great potential for confidential information encryption/decryption (InfoED) applications. However, it is rather challenging to ensure high security and achieve high readout efficiency in perovskite SRL-based InfoED. Herein, we present a unique InfoED strategy using 2D hybrid organic-inorganic perovskites via delicate organic-cation engineering, benefiting from the high contrast and quick response of their photoluminescence behaviors. Indistinguishably encrypted information can be efficiently decrypted through triple-key implementation (i.e., ultraviolet-light irradiation, temperature control, and narrow-bandpass filtering) that operates in multiple switching modes, enabling us to demonstrate extremely high security by adopting dot-matrix patterning scenarios that are virtually uncrackable. As a proof of principle, a simple 2 × 2 patterning can yield a code dictionary with random variants as high as ∼10<sup>47</sup>, which will take as long as ∼10<sup>22</sup> years to crack using the hitherto fastest supercomputer, El Capitan. Our perovskite SRL-based InfoED strategy provides a promising solution for information security based on optical encryption.

Mesoporous Hollow Carbon Spheres/Nanofibers Anchored With Conductive Bimetallic for Efficient Microwave Absorption ABSTRACT To break electromagnetic wave absorption (EMA) tech's single‐attenuation bottleneck, enhancing multi‐wave absorption synergy in composites is key for microstructure design. This study uses mesoporous hollow carbon spheres to make metal nanospheres with cobalt, iron, and nickel nanoparticles, then encapsulates them via electrospinning into a unique carbon shell–cavity–core fiber structure. It is light, low‐density, and defect‐rich. The numerous heterogeneous interfaces embedded in carbon fiber endow it with excellent conductivity and high specific surface area. Based on this, the three‐dimensional conductive network further optimizes the transmission loss path of incident electromagnetic waves. Thanks to the effective cooperative of multiple absorption mechanisms, the NiFe 2 O 4 @PCHMs/CF composite material achieves an of −50.05 dB, and its maximum effective absorption bandwidth (EAB max ) reaches 7.68 GHz at a thickness of 7.2 mm. This outstanding performance far exceeds that of the NiCo@PCHMs/CF and CoFe 2 O 4 @PCHMs/CF fiber samples. This study not only explores the potential applications of electrospinning materials, but also provides new insights for the optimization design of electromagnetic wave (EMW) absorbing materials.

Photopharmacological activation of adenosine A1 receptor signaling suppresses seizures in a mouse model for temporal lobe epilepsy Up to 30 % of epilepsy patients suffer from drug-resistant epilepsy (DRE). The search for innovative therapies is therefore important to close the existing treatment gap in these patients. The adenosinergic system possesses potent anticonvulsive effects, mainly through the adenosine A<sub>1</sub> receptor (A<sub>1</sub>R). However, clinical application of A<sub>1</sub>R agonists is hindered by severe systemic side effects. To achieve local modulation of A<sub>1</sub>Rs, we employed a photopharmacological approach using a caged version of the A<sub>1</sub>R agonist N<sup>6</sup>-cyclopentyladenosine, termed cCPA. We performed the first in vivo study with intracerebroventricularly (ICV) administered cCPA to investigate the potential to photo-uncage and release sufficient amounts of cCPA in the hippocampus by local illumination in order to suppress hippocampal excitability and seizures in mice. We validated the presence of cCPA in the hippocampus after ICV injection and explored its pharmacokinetic profile and in vivo stability. Using hippocampal evoked potential recordings, we showed a reduction in hippocampal neurotransmission after photo-releasing CPA, similar to that obtained with ICV injection of CPA. Furthermore, in the intrahippocampal kainic acid mouse model for DRE, photo-release of CPA in the epileptic hippocampus resulted in a strong suppression of seizures. Finally, we demonstrated that intrahippocampal photo-release of CPA resulted in less impairment of motor performance in the rotarod test compared to ICV administration of CPA. These results provide a proof of concept for photopharmacological A<sub>1</sub>R modulation as an effective precision treatment for DRE.

Strain-induced lead-free morphotropic phase boundary Enhanced susceptibilities in ferroelectrics often arise near phase boundaries between competing ground states. While chemically-induced phase boundaries have enabled ultrahigh electrical and electromechanical responses in lead-based ferroelectrics, precise chemical tuning in lead-free alternatives, such as (K,Na)NbO<sub>3</sub> thin films, remains challenging due to the high volatility of alkali metals. Here, we demonstrate strain-induced morphotropic phase boundary-like polymorphic nanodomain structures in chemically simple, lead-free, epitaxial NaNbO<sub>3</sub> thin films. Combining ab initio simulations, thin-film epitaxy, scanning probe microscopy, synchrotron X-ray diffraction, and electron ptychography, we reveal a labyrinthine structure comprising coexisting monoclinic and bridging triclinic phases near a strain-induced phase boundary. The coexistence of energetically competing phases facilitates field-driven polarization rotation and phase transitions, giving rise to a multi-state polarization switching pathway and large enhancements in dielectric susceptibility and tunability across a broad frequency range. Our results open new possibilities for engineering lead-free thin films with enhanced functionalities for next-generation applications.

Tellurium-Terminated MXene Synthesis via One-Step Tellurium Etching With the rapid development of two-dimensional MXene materials, numerous preparation strategies have been proposed to enhance synthesis efficiency, mitigate environmental impact, and enable scalability for large-scale production. The compound etching approach, which relies on cationic oxidation of the A element of MAX phase precursors while anions typically adsorb onto MXene surfaces as functional groups, remains the main prevalent strategy. By contrast, synthesis methodologies utilizing elemental etching agents have been rarely reported. Here, we report a new elemental tellurium (Te)-based etching strategy for the preparation of MXene materials with tunable surface chemistry. By selectively removing the A-site element in MAX phases using Te, our approach avoids the use of toxic fluoride reagents and achieves tellurium-terminated surface groups that significantly enhance sodium storage performance. Experimental results show that Te-etched MXene delivers substantially higher capacities (exceeding 50% improvement over conventionally etched MXene) with superior rate capability, retaining high capacity at large current densities and demonstrating over 90% capacity retention after 1000 cycles. This innovative synthetic strategy provides new insight into controllable MXene preparation and performance optimization, while the as-obtained materials hold promises for high-performance sodium-ion batteries and other energy storage systems.

Foliar application of fullerenol and zinc oxide nanoparticles improves stress resilience in drought-sensitive Arabidopsis thaliana This study aimed to characterise the chemical properties of fullerenol nanoparticles (FNP) and zinc oxide nanoparticles (ZnO nano), as well as their physiological and molecular effects following foliar application on Arabidopsis thaliana. Additionally, we explored the potential synergistic impact of combining ZnO nano with FNPs to enhance plant resilience under drought stress conditions. Chemical characterisation confirmed the successful formation of a stable FNP-ZnO aggregate. The previously established biostimulatory effects of fullerenol at micromolar concentrations were reaffirmed, highlighting its unique chemical properties. We demonstrated that a low dose (10 mg/L) of ZnO nano, used as a foliar application for the first time in Arabidopsis thaliana, positively influenced drought stress acclimatization. Our findings indicate that FNP and ZnO alleviate oxidative stress by mitigating the impact of reactive oxygen species (ROS), modulating antioxidant enzyme activities, and stabilising redox balance. Photosynthetic performance, stomatal conductance and water-use efficiency were optimized, particularly through fullerenol application, due to its unique antioxidative and hygroscopic properties. We further analyzed the expression of selected drought-response genes involved in ABA-dependent and ABA-independent water deficit acclimation in Col-0 wild-type and pp2ca-1 drought hypersensitive mutant backgrounds. Our results revealed distinct gene expression changes in response to nanoparticle treatments, demonstrating modulation of ABA signaling and stress-related transcription factors. The combined application of FNP and ZnO exhibited unique, synergistic protective effects in drought acclimation. Future research will further elucidate the direct mechanisms linking these physiological outcomes to specific nanoparticle properties, paving the way for innovative strategies in sustainable agriculture.

Backbone Engineering of Bithiophene Imide Dimer‐Based Polymeric Mixed Ionic‐Electronic Conductors for High‐Performance n‐Type Organic Electrochemical Transistors Polymeric mixed ionic-electronic conductors (PMIECs) are gaining significant attention due to their potential applications in organic electrochemical transistors (OECTs). However, the performance of n-type OECTs still lags behind that of their p-type counterparts. Here, the structure-performance correlation of fused bithiophene imide dimer (BTI2)-based PMIECs is systematically investigated with the backbone evaluation from acceptor-strong donor (A-SD) to acceptor-donor (A-D), to acceptor-weak donor (A-WD), to acceptor-weak acceptor (A-WA), and finally to A-A structures. Compared to other PMIECs, the A-A backbone-based PMIEC PBTI2g-BTI features the most suppressed lowest unoccupied molecular orbital energy level, a highly planar backbone, and superior n-type electrochemical dopability. Consequently, polymer PBTI2g-BTI delivers an exceptional unipolar n-type OECT performance with a high electron mobility of 0.25 cm<sup>2</sup> V⁻¹ s⁻¹ and a remarkable µC<sup>*</sup> value of 63.79 F cm⁻¹ V⁻¹ s⁻¹, both of which are significantly higher than those of other types of PMIECs. This study demonstrates that the A-A backbone strategy is an effective approach to developing high-performance n-type PMIECs for applications in OECTs.

Peptide‐Carbazolyl Cyanobenzene Conjugates: Enabling Biomolecule Functionalization via Photoredox and Energy Transfer Catalysis Since their discovery in 2012, carbazolyl (iso)phthalonitrile (Cz(I)PN) derivatives have found significant applications as photocatalysts (PCs) in organic chemistry. Herein, we introduce two efficient methods for incorporating carbazolyl cyanobenzenes into various peptide sequences. The first method involves a photomediated decarboxylative functionalization of the C-terminus of peptides, leading to the formation of various carbazolyl benzonitrile (CzBN) derivatives. The second method exploits a cysteine-selective S<sub>N</sub>Ar reaction on a fluorinated arene precursor, resulting in novel peptide-3CzIPN (triscarbazolyl-isophthalonitrile) conjugates. Both types of conjugates maintain delayed fluorescence properties, exhibit similar or wider redox potential, and possess higher excited state energy when compared to currently used cyanoarenes. We demonstrated the photocatalytic activity of these conjugates first through a photo-mediated peptide C-terminal decarboxylative alkynylation. Then, water-soluble peptide conjugates were used to catalyze a thiol-ene reaction on cysteine in aqueous media. Finally, we achieved protein labeling via aryl azide excitation both in vitro and at the cellular level using peptide-CzIPN conjugates. By incorporating a peptide ligand of the protein integrin α<sub>v</sub>β<sub>3</sub>, proximity-driven labeling next to this target was realized by aryl azide excitation in living cells, showing an excellent overlap with antibody-based imaging. These findings reveal the potential of cyanoarene-peptide conjugates for proximity-driven photochemistry in a complex biological context.
