The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the suggestion that Ryugu/CI chondrites formed in a different region of the accretion disk, possibly around the orbits of Uranus and Neptune. We show that, like for Fe, Ryugu and CI chondrites also have indistinguishable Ni isotope anomalies, which differ from those of other carbonaceous chondrites. We propose that this unique Fe and Ni isotopic composition reflects different accretion efficiencies of small FeNi metal grains among the carbonaceous chondrite parent bodies. The CI chondrites incorporated these grains more efficiently, possibly because they formed at the end of the disk’s lifetime, when planetesimal formation was also triggered by photoevaporation of the disk. Isotopic variations among carbonaceous chondrites may thus reflect fractionation of distinct dust components from a common reservoir, implying CI chondrites/Ryugu may have formed in the same region of the accretion disk as other carbonaceous chondrites. © 2024, CC BY.

Proton‐coupled electron‐transfer oxidation of a Ru II −OH 2 complex, having an N‐heterocyclic carbene ligand, gives a Ru III −O . species, which has an electronically equivalent structure of the Ru IV =O species, in an acidic aqueous solution. The Ru III −O . complex was characterized by spectroscopic methods and DFT calculations. The oxidation state of the Ru center was shown to be close to +3; the Ru−O bond showed a lower‐energy Raman scattering at 732 cm −1 and the Ru−O bond length was estimated to be 1.77(1) Å. The Ru III −O . complex exhibits high reactivity in substrate oxidation under catalytic conditions; particularly, benzaldehyde and the derivatives are oxidized to the corresponding benzoic acid through C−H abstraction from the formyl group by the Ru III −O . complex bearing a strong radical character as the active species.

Despite intensive research on sustainable elastomers, achieving elastic vitrimers with significantly improved mechanical properties and recyclability remains a scientific challenge. Herein, inspired by the classical elasticity theory, we present a design principle for ultra-tough and highly recyclable elastic vitrimers with a defined network constructed by chemically crosslinking the pre-synthesized disulfide-containing polydimethylsiloxane (PDMS) chains with tetra-arm polyethylene glycol (PEG). The defined network is achieved by the reduced dangling short chains and the relatively uniform molecular weight of network strands. Such elastic vitrimers with the defined network, i.e., PDMS-disulfide-D, exhibit significantly improved mechanical performance than random analogous, previously reported PDMS vitrimers, and even commercial silicone-based thermosets. Moreover, unlike the vitrimers with random network that show obvious loss in mechanical properties after recycling, those with the defined network enable excellent thermal recyclability. The PDMS-disulfide-D also deliver comparable electrochemical signals if utilized as substrates for electromyography sensors after the recycling. The multiple relaxation processes are revealed via a unique physical approach. Multiple techniques are also applied to unravel the microscopic mechanism of the excellent mechanical performance and recyclability of such defined network.

In this paper, we investigate topological states in a two-dimensional distorted Kagome lattice with next- nearest-neighbour (NNN) coupling. We show that introducing NNN coupling leads to the emergence of a new type of higher-order corner states in a non-trivial topological phase. Using near-field scanning technique, we verify our theoretical predictions in the microwave frequency range and demonstrate field profiles for both conventional and new type of corner states. The experimental results are in perfect agreement with numerical simulations of finite structure.

Photonic actuators, serving as an emerging kind of intelligent stimuli-responsive material, can exhibit the abilities to change their structural colors/fluorescence and shapes under specific external stimuli, which have demonstrated essential applications in the fields of intelligent soft robotics, sensors, bionics, information storage, anti-counterfeiting, and energy harvesting. In this review, we reported the state-of-the-art research progress of stimuli-responsive photonic actuators classified on the basis of the material type and focusing on the actuation mechanisms, design principles, and processing techniques. We also broadly summarized the relative applications of photonic actuators in bionics, intelligent robots, sensors, and so on. Finally, a vision for the challenges in the area and future promising directions of stimuli-responsive photonic actuators is presented.

Dissipative self-assembly (DSA) system requires a continuous supply of fuels to maintain the far-from-equilibrium assembled state. Living organisms exist and operate far from the thermodynamic equilibrium by continuous consumption of energy taken from the surroundings, so how to realize the construction of the artificial DSA system has attracted much attention by researchers all over the world. Owing to dynamic controllable noncovalent interactions, artificial supramolecular DSA systems have achieved higher functions fueled by various types of energy, such as chemical fuels, light, electric energy, acoustic energy, and mechanical energy. Upon the input of external fuels, nonactive precursors can be activated to form building blocks at higher energy levels and then self-assemble into transient supramolecular structures. As the proceeding of deactivation reaction, the building blocks with higher energy level dissipate back to the initial precursors, resulting in the disassembly process, to complete a full cycle. In this review, we summarize the recent advances of artificial supramolecular DSA systems on its construction strategies and energy-fueled regulation approaches. The applications of supramolecular DSA systems in luminescence modulating, information encryption, self-regulating gels, drug delivery, and catalysis are also discussed. We hope that this review article will facilitate further understanding and development of DSA systems.
