Designing multicomponent reticular structures has been limited by the availability of suitable structural blueprints. Recently, a groundbreaking work reported by Eddaoudi and co-workers in Science has introduced a merged-net approach that expands the design space of reticular chemistry by combining edge-transitive nets, accelerating the discovery of intricate reticular materials.

Micro-nano capsules have garnered significant attention due to their potential applications. However, the capacity to load these capsules with various substances and induce dynamic color-changing effects remains an unexplored area of research. Here, inspired by the color-changing abilities of tree frogs, we developed a dual-compartment composite microcapsule that responds to multiple stimuli. This microcapsule was fabricated by electrostatically adsorbing nanocapsules onto its surface, enabling full-spectrum color changes in response to UV light and temperature variations. By precisely regulating the number of nanocapsules on the surface of the composite microcapsules and adjusting the micro-nano-level coloration on individual composite microcapsules, a variety of stable and coordinated colors can be achieved. The microcapsules possess stable and fully reversible multicolored changing properties and can effectively be used as anti-counterfeiting inks in the screen-printing process. This advancement holds wide-ranging potential applications in the next generation of anti-counterfeiting labels and information encryption.

Chiral-induced spin selectivity (CISS) has been widely used in electrocatalysis due to its properties of inducing spin polarization and fast charge transfer. The outstanding performance of the CISS effect in electrocatalytic reactions brings new avenues for the development of electrocatalysis. In this review, we first illustrate the prospects of the CISS effect for application in electrocatalysis by introducing two important features (induced spin polarization and rapid charge transfer). Subsequently, we summarize the current status of the application of the CISS effect in electrocatalytic reactions. In addition, we classify and summarize the potential CISS catalysts based on the above research status. Finally, we outline the breakthrough points of the CISS effect in a wide range of electrocatalytic applications and propose the possibilities, future prospects, and limitations of the CISS effect in electrocatalysis.

The delicate processes following the photoexcitation underpin technologies and applications related to light utilization and conversion. However, understanding the relaxation mechanisms of excited states, especially in aggregates, remains challenging. In a recent study published in Chem, Prof. Li and co-workers combined machine learning techniques with multiscale theoretical calculation methods to create a powerful “computational microscopy,” enabling direct observation of the excited-state dynamics in aggregates and identification of the origin of reduced non-radiative decay in aggregation-induced emission.

Hot carriers generated by localized surface plasmon resonance (LSPR) in metal nanoparticles can drive chemical reactions such as secondary metal deposition and catalytic reactions. Rationally designing plasmonic nanostructures requires understanding how particle geometry impacts hot carrier reaction dynamics. Here we use liquid-phase transmission electron microscopy (LP-TEM) and an electron radiolysis-resistant solvent to visualize hot carrier-mediated silver deposition and gold nanorod (AuNR) reshaping. AuNRs grew primarily in the transverse direction and displayed tip sharpening and preferential growth at LSPR hotspots. Ex situ white-light illumination produced similar morphological and compositional changes, whereas radiolysis products did not. Growth dynamics relative to electron beam flux and AuNR orientation were consistent with numerical simulations of hot carrier generation. Isolating hot carrier-induced redox processes on AuNRs during LP-TEM enabled quantifying spatially varying hot electron reaction dynamics. This approach is expected to enable quantifying and visualizing a broad range of plasmonic carrier-mediated reactions.

Bovine pericardium, a tissue commonly used to make artificial heart valves, fulfills two fundamental mechanical requirements: a low modulus to ensure opening and closing in cyclic pulsatile flow and a high fatigue threshold to prevent crack growth. The tissue consists of a soft matrix and crimped fibers. Inspired by this architecture, we develop a composite of a soft polymer matrix and a knitted fabric. When the stretch is small to modest, the knitted fabric is easily stretched, so that the composite is soft. When the stretch is large, the knitted fabric is stiff and strong, so that the composite resists fatigue crack growth. The mechanical behavior of the composite is comparable to that of bovine pericardium. The composite has an exceptionally long fatigue life, enduring 25 million cycles of pulsatile flow, two orders of magnitude longer than the polymer matrix. This soft and fatigue-resistant composite may find broad applications in biomedicine.

Rapid data growth highlights the increasing demand for high-density storage solutions. Multiplexed optical recording based on synthetic inorganic nanoparticles represents the next generation of data storage. However, diverse photophysical properties of nanoparticles reduce their reliability and information density. Here, we present a highly programmable polychromatic DNA tetrahedral framework (PDTF) that enables precise control over their optical performances. By programming the size of PDTFs, we reduce the feature size of the recording medium to 3.4 nm, which was 41-fold smaller than that of commercially available Blu-ray technology. PDTF chains with up to 47 million distinct color codes further enhance optical storage with higher information capacity. Additionally, nanopatterning technology integrates the PDTFs into on-chip architectures, achieving an impressive density of 25.9 Gb/cm2. Finally, the PDTFs demonstrate excellent re-writability and long-term stability (10,826 years at room temperature), exhibiting promising potential in high-density and secure data storage applications.

Flexible piezoresistive sensors have attracted great attention for the real-time monitoring of sleep apnea syndrome (SAS) through respiratory airflow. Although two-dimensional ultrathin Ti3C2 is regarded as a promising piezoresistive material, its poor structural compressibility and antioxidation limit its practical applications. Here, an innovative atomic sulfur-bonded strategy is proposed to fabricate large-sized, crumpled, and antioxidative Ti3C2/Na2S (TS) flakes for preparing flexible piezoresistive sensors. The fundamental mechanism is rooted in the synergistic effect of lateral boundary assembly of Ti3C2 nanosheets into large flakes (∼7 μm), lattice distortion to induce crumpled structures, and edge passivation by S2− ions to mitigate oxidation (105 days). The crumpled microstructure provides abundant voids for enhanced compressibility and contact site variability, resulting in a 5-fold sensitivity improvement over the Ti3C2 sensor and an ultralow detection limit of 0.2 Pa. We demonstrate the practical application of highly sensitive and stable piezoresistive sensors integrated into a respiratory monitoring system for SAS detection.

Photoluminescence (PL) emission in two-dimensional (2D) materials is of great interest for nanophotonics applications. While excitonic emission has been observed in numerous 2D materials, tunable multi-band luminescence is rare. Here, we present single-crystalline AgErP2Se6, a 2D material that exhibits bright, multi-band PL emission from Er3+ ions within the lattice. The emission bands cover a wide range (350–1,550 nm), with ultra-narrow (as low as 0.5 nm at room temperature) emission peaks and room temperature lifetimes up to ∼4 μs. The intensities of the PL emission bands from the single crystals depend strongly on temperature and pressure, enabling sensing over a wide temperature and pressure range. Furthermore, the PL persists in exfoliated flakes down to at least 11 nm thick and demonstrates thickness-dependent Purcell enhancement. This work establishes 2D AgErP2Se6 as a multi-band luminescent emitter and sensor, poised to enable integration into a number of optoelectronic and nanophotonic applications.

The exploration of biomimetic materials for bioelectronics is driving transformative advancements in medical technology and beyond. Drawing inspiration from nature’s intricate designs, these materials hold immense potential for creating bioelectronics that integrate seamlessly with living tissues. This work highlights three key biomimetic strategies in the current bioelectronics community: structural design, material properties, and natural processes. We demonstrate how these approaches significantly enhance the bioelectronic performance in the aspects of bio-signal acquisition, transduction, and analysis, addressing critical challenges in current biomedical technologies. By incorporating these principles, biomimetic materials and technologies are poised to revolutionize the conventional medical model, fostering the development of more intelligent, efficient, and biocompatible bioelectronic devices.
