Self-assembling peptides have great potential in nanotechnology. Here, we introduce the naphthalene-modified dipeptide isoleucine-phenylalanine (2NapIF) as a modular system for creating various nanostructures via self-assembly, including fibers, nanotubes, and bundles, resulting from the addition of salts. Mechanical stirring is crucial for developing certain supramolecular architectures. Using cryo-electron microscopy (cryo-EM), we found that the structural organization of these nanostructures is primarily driven by hydrophobic stacking of aromatic rings and hydrogen bonding among peptide atoms. The diversity in packing arises from the ability of 2NapIF to adopt multiple conformations, with our study revealing 18 distinct conformations within a KCl-induced nanotube. This results in a large asymmetric unit containing 18 molecules, with 18 conformations, that could never have been predicted with current tools. This modular system has potential applications in creating innovative materials, including robust, salt-responsive “noodles” that exceed a meter in length.

Geometric classifications of 3D pores are useful for studying relationships between pore geometry and function in granular materials. Pores are typically characterized by size, but size alone cannot explain 3D phenomena like transport. Here, we implement a K-nearest neighbor (KNN)-based pore classification approach emphasizing shape-related properties. We find that pore types produced in randomly packed systems resemble those of ideal, hexagonally packed systems. In both random and perfect systems, pores tend to configure as octahedrons (Os) and icosahedrons (Is). We demonstrate the physical implications of this by running flow simulations through a granular system and observe differences in fluid dynamic behaviors between pore types. We finally show that the O/I pore distribution can be tuned by modifying particle properties (shape, stiffness, and size). Overall, this work enables analysis of granular system behaviors by 3D pore shape and informs system design for desired distributions of pore geometries.

Synthetic hydrogels provide powerful material platforms to engineer cellular microenvironments with control over stiffness, viscoelasticity, porosity, degradability, and biochemical signals. Here, we demonstrate how orthogonal crosslinking reactions allow fabrication of covalent adaptable networks to tailor photopolymerizable bioresin formulations relevant for tissue engineering. Specifically, we synthesize multifunctional poly(ethylene glycol) (PEG) macromers containing dynamic boronate ester bonds and dithiolane and norbornene moieties that allow for photopolymerization and projection-based biofabrication. These materials are used to print human mesenchymal stromal cells (MSCs) in formulations where the ratio of elastic versus adaptable crosslinks is engineered to study and manipulate MSC spreading, actin structure, and macroscopic material-level deformation. We demonstrate how material and print parameters, peptide ligands, actomyosin-modulating drug treatments, and cell types influence cell-material interactions and emergence of morphogenesis that is uniquely enabled by viscoelasticity. The presented materials introduce a versatile strategy for spatiotemporal control over dynamic mechanical properties in cell-laden matrices.

The commercialization of inverted perovskite solar cells (PSCs) is urgently limited by stability, an issue closely related to the heterointerface. In this work, we rationally synthesized two phenanthroline-based isomers—2-(3,4-dimethoxyphenyl)-1,10-phenanthroline (J2) and 5-(3,4-dimethoxyphenyl)-1,10-phenanthroline (J5)—as novel interfacial modifiers to enhance the interface stability. The J2 with co-directional binding sites was incorporated into [6,6]-phenyl-C₆₁-butyric acid methyl ester (PCBM) to interact with it in a π-π manner and coordinate with perovskite, strengthening the interface adhesion. The J5 with opposite-directional binding sites was incorporated into MeO-4PACz to π-π interact with it and coordinate with the FTO substrate and perovskite, respectively, thus stabilizing MeO-4PACz and reinforcing interface. Owing to the improved interfacial mechanical durability and reduced interfacial carrier recombination, the 0.08 cm2-PSC and 1 cm2-PSC achieved efficiencies of 26.55% and 25.00%, respectively. Moreover, unencapsulated devices can retain 92% of their initial efficiency after operating 3,000 h under continuous 1-sun illumination and 91% after 150 harsh thermal cycles.
稳定性是制约倒钙钛矿太阳能电池（PSCs）商业化的重要因素，而稳定性是与异质界面密切相关的问题。本文合理合成了2-（3,4-二甲氧基苯基）-1,10-菲罗啉（J2）和5-（3,4-二甲氧基苯基）-1,10-菲罗啉（J5）两种邻菲罗啉异构体作为新型界面改性剂，提高了界面稳定性。将具有共向结合位点的J2掺入[6,6]-苯基- c₆₁-丁酸甲酯（PCBM）中，以π-π方式与之相互作用，并与钙钛矿配位，增强了界面附着力。将具有相反方向结合位点的J5加入到MeO-4PACz中，使π-π与MeO-4PACz相互作用，并分别与FTO底物和钙钛矿配位，从而稳定MeO-4PACz并增强界面。0.08 cm - psc和1 cm - psc的效率分别为26.55%和25.00%，这是由于提高了界面力学耐久性和减少了界面载流子复合。此外，未封装的设备在连续1个太阳照射下运行3000小时后可以保持92%的初始效率，在150次严酷的热循环后可以保持91%的初始效率。

Natural soils form hierarchical structures through physicochemical self-assembly—a principle that can be harnessed to design sustainable, high-performance building materials. We present a scalable approach that tunes kaolinite self-assembly via controlled chemical environment and guar gum (GG) addition, enhancing strength while retaining 3D printability. Physicochemical, rheological, and mechanical analyses show that pH regulates clay self-assembly by altering particle surface charge, whereas GG restructures networks through polymer bridging. Multiscale characterization reveals that although similar microstructures can develop across compositions when stabilized with sufficient biopolymer at different pH, the pathways leading to their formation differ. Networks are formed primarily through colloidal interactions (van der Waals and electrostatic forces) or induced by biopolymer bridging. Despite appearing structurally similar, biopolymer-assembled networks exhibit significantly greater strength—exceeding 110% improvement—compared to those formed through colloidal interactions. These results highlight that the origin of microstructure critically governs performance, introducing a new designing principle for sustainable, printable materials.

Metal-halide X-ray scintillators have substantial potential in various applications, including medical diagnosis, nondestructive inspection, security checking, and space exploration. However, it has been found that the formidable humidity decomposition of conventional scintillators remains a great obstacle in advancing next-generation X-ray imaging technology. Herein, we report a nontoxic copper-halide scintillator featuring an organic framework structure, where hydrophobic long-chain molecules impart exceptional waterproof properties to the scintillator even after being soaked in water for 500 days. Moreover, a flexible film achieved from the stable scintillator demonstrates remarkable radiation robustness along with a high spatial resolution of 16.6 lp mm−1 and a low limit of detection of 33.75 nGyair s−1. Finally, leveraging color and spatial reconfiguration technologies enables impressive 3D X-ray imaging, revealing clear and distinct internal details of objects. This work highlights significant advantages of our waterproof scintillator for efficient 3D X-ray imaging, paving the way for its diverse applications in challenging environments.

Flexible, self-powered thermoelectric temperature sensors with high reliability are increasingly recognized as essential components in tactile perception, wearable technologies, and medical monitoring. To fulfill the performance requirements of these applications—specifically, achieving high Seebeck coefficients and superior resolution—traditional fabrication strategies typically rely on intricate molecular engineering, microscale structural optimization, or macroscale topological design. However, these approaches often involve complex manufacturing processes and elevated production costs, constraining large-scale deployment. Here, we propose a simple multilayer assembly approach that harnesses a self-permeation effect to enable the facile and cost-effective fabrication of flexible thermoelectric sensors with significantly improved sensitivity and resolution. By inducing intensive p-n heterojunctions through self-permeation and leveraging phonon scattering at multilayer-structured interfaces, the obtained sensor exhibits an unprecedented sensitivity of 1,203.6 μV K−1 and an ultimate temperature difference detection capability of 0.001 K, showcasing great potential for applications in three-dimensional environmental monitoring and bionic robotic tactile sensing.

Natural muscles feature resilient actuation, but currently developed artificial muscle fibers do not. The main challenge is serious plastic elongation, especially when artificial muscle fibers are operated at heavy loads, significantly limiting their applications. We report a resilient artificial muscle fiber that deploys an elastic sheath. The sheath enables full lengthwise recovery of the coiled artificial muscle fiber straightened at 375% strain. This muscle fiber produces natural muscle-like resilient actuation, which features elastic elongation when bearing heavy loads and consistent contractions at load-balanced muscle lengths. Two muscle fibers connected in an antagonistic structure, amounting to ∼8% of the weight of an electrical rudder system, efficiently control the flight attitude of a commercial ornithopter. An adaptive pressure band based on these muscle fibers provides rhythmic pressure to prevent venous diseases. Such resilient muscle fibers can offer important potential in robotics and wearable technologies that require high durability and adaptability.

Metal halide perovskites (MHPs) have emerged as promising materials for next-generation display and lighting technologies, owing to their wide color tunability, high color purity, narrow emission bandwidths, high photoluminescence quantum yields, and compatibility with low-cost solution processing techniques. While significant progress has been made in monochromatic perovskite light-emitting diodes (PeLEDs), with external quantum efficiencies exceeding 20%, their commercialization still faces critical challenges in device engineering and stability. This review provides a comprehensive overview of recent advances in multi-color PeLEDs. We first introduce their operating principles and compare them with other emissive technologies. We then discuss the potential of MHPs for tunable multi-color and white-light emission, with an emphasis on phase segregation issues and lead-free compositions. The review further explores key device engineering strategies, including single-layer white emissions, color patterning techniques, and the emerging concept of hybrid tandem PeLEDs. By covering compositional engineering, degradation mechanisms and mitigation approaches, and advanced device architectures, this review aims to guide future research and accelerate the development of efficient and stable multi-color PeLEDs.

While significant progress has been made in monochromatic perovskite light-emitting diodes (PeLEDs), with external quantum efficiencies exceeding 20%, their commercialization still faces critical challenges in device engineering and stability. This review provides a comprehensive overview of recent advances in multi-color PeLEDs. We first introduce their operating principles and compare them with other emissive technologies. We then discuss the potential of MHPs for tunable multi-color and white-light emission, with an emphasis on phase segregation issues and lead-free compositions. The review further explores key device engineering strategies, including single-layer white emissions, color patterning techniques, and the emerging concept of hybrid tandem PeLEDs.
