Bio-based plastics offer the advantage of biodegradability over traditional petroleum-based plastics, enabling natural reintegration into the environment and positioning them as a more sustainable alternative. DNA, as a natural biopolymer, exhibits excellent biocompatibility and degradability. However, the mechanical strength of currently biomass DNA-based materials is inferior to that of other bio-based and petroleum-based plastics. In this work, DNA plastics with a ″brick-and-mortar" structure were fabricated using DNA extracted from onions through bidirectional freezing, water vapor annealing, and compression densification. This biomimetic design significantly enhances the fracture toughness (∼1.5 MPa·m1/2) while possessing a high elastic modulus (∼560 MPa) of DNA plastic, making it superior or comparable to existing bio-based plastics and petroleum-based plastics, and thus positioning it as a potential structural material. Analysis of crack propagation behavior in DNA plastics reveals that their high toughness stems from a hierarchical ″brick-and-mortar″ structure operating across multiple length scales, facilitating a multiscale fracture process from macroscopic to molecular levels. Furthermore, these DNA plastics can be efficiently recycled in aqueous environments and fully biodegraded by enzymes, demonstrating strong environmental friendliness and significant potential for sustainable development. © 2025 The Authors.

Charge density wave (CDW) and their interplay with correlated and topological quantum states are at the forefront of condensed matter research. The 4Hb−TaS2 is a CDW ordered quantum heterostructure that is formed by alternative stacking of Mott insulating 1T-TaS2 and Ising superconducting 1H-TaS2. While the 13×13 and 3×3 CDWs have been respectively observed in the bulk 1T-TaS2 and 2H-TaS2, the CDWs and their pivotal role for unconventional superconductivity in the 4Hb−TaS2 remain unsolved. In this Letter, we reveal the two-dimensional (2D) 13×13 chiral CDW in the 1T layers and intraunit cell coupled 2D 2×2 CDW in the 1H and 1H' layers of 4Hb−TaS2. Our results establish 4Hb−TaS2 a 2.5D quantum heterostructure, where 2D quantum states emerge from 3D crystalline structure.

The design and synthesis of porous materials represent a critical strategy for advancing multifunctional applications of phthalonitrile resins. By coupling the intrinsic thermomechanical stability derived from heterocyclic macromolecular architectures with the functional benefits imparted by micro- and nanoporous structures, these materials offer enhanced high-performance options to meet demanding service conditions. Herein, we present a novel multi-step methodology for fabricating nanoporous phthalonitrile aerogel composites (PNAC), comprising phthalonitrile solution formulation, fiber reinforcement impregnation, sol-gel reaction, ambient-pressure drying, and post-curing. The resulting aerogel matrix features a three-dimensional porous skeleton composed of interconnected nanoparticles. Thermal analysis reveals exceptional stability, with a 5 % weight loss temperature (Td5) of 466 °C and a char yield of 55 wt% at 1000 °C. Incorporation of needled quartz fiber felt significantly improves the dimensional stability during processing. The prepared PNAC demonstrates a unique combination of properties: low density (0.28 g cm3), ultralow thermal conductivity (54.3 mW·m−1·K−1 at 25 °C;58.7 mW·m−1·K−1 at 200 °C), pronounced hydrophobicity (static contact angle: 141°), and self-extinguishing behavior. This multifunctional profile positions PNAC as a promising candidate for extreme-environmental applications. © 2025 Elsevier Ltd

Conductive hydrogels with water-enriched pores have shown great potential in electromagnetic wave protection and flexible wearable electronics. However, hydrogel with high water content often results in some challenges such as water loss and low-temperature freezing. In this study, porous gelatin/ChCl/MXene Ti3C2Tx (GCM) hydrogels were prepared via a simple, scalable one-pot method. The introduction of ChCl forms abundant hydrogen bonds in GCM hydrogel, which endows the hydrogel long-term anti-drying (30 days) and anti-freezing abilities (-30 °C). Due to the synergistic effects of the porous structure, highly conductive MXene and water molecules, the electromagnetic interference (EMI) shielding effectiveness (SE) reach up to 108 dB in the X-band. Significantly, the effects of water molecules on EMI SE are quantitatively identified by controlling the water content in the GCM hydrogels. Moreover, the gelatin-based hydrogel exhibits super-elasticity (0.25 MPa at 80% strain) and demonstrates no significant decrease in EMI SE after 100 compression cycles. Finally, the excellent pressure-sensing capabilities of GCM hydrogel enable sensitive and reliable detection in human motion and smart coding. Therefore, the developed GCM hydrogel demonstrates promising application prospects in the fields of EMI shielding and sensing for wearable electronic devices. © 2025, The Authors.

The Li-CO2battery has been highly rated as an intriguing technique for balancing the carbon cycle for years, but it is still significantly challenged by the obstacles such as limited reversibility, sluggish kinetics,and poor energy efficiency. Hence, the design and development of advance catalysts that can enhance the kinetics and reversibility of the CO2electrochemical cycling reactions are considered the imperative tasks. Transition metal-based catalysts are widely considered appealing owing to their unfilled dorbitals, rich and adjustable valences, as well as processibility. In this review, the working mechanism and the key issues of the CO2electrochemical cycling reaction are discussed first. Then the strategies for composition and structure design of different type of transition metal-based catalysts are highlighted,including their benefits, limitations, and the ways to implement these strategies. Finally, based on the pioneering research, the perspectives on the challenges and key points for the future development of cathode catalyst are proposed.

Polymer materials possess unique chain connectivity structure, which endows them with distinctive features in terms of structure, thermodynamics, and dynamics. Traditional polymer physics focuses on how this unique chain connectivity governs the microscopic dynamics and interactions in polymer systems, differentiating their properties from those of small-molecule systems. This review revisits our several efforts made using molecular simulations to explore specific, unresolved issues in polymer systems, offering readers a personal perspective on the significant role of molecular simulation methods in advancing polymer physics. The review discusses the effects of chain connectivity from the perspectives of entanglement constraints, chain segment stretching, and orientation, introducing phenomena including chain orientation tumbling and shear banding in nonlinear polymer rheology, crystallization in biaxially stretched and entanglement-modified polymer melts, and bond orientation-determined stress in glassy polymers. © 2025 Elsevier Ltd
