The demand for deep human-machine fusion propels the development of artificial neuron. However, emulating the neuronal spiking in aqueous environments remains challenging. Inspired by the biocompatibility of metal-organic frameworks (MOFs), Zhao et al. reported a MOF neuron with biochemical perception for the first time. Based on the real neurotransmitter—dopamine (DA) mediation, the neuron not only emulated some sophisticated neuronal functions but also controlled peripheral equipment, providing a new perspective for artificial neuron development.

A recent study published in National Science Review analyzes a new type of solar energetic particle event with faster particles arriving later than slower ones. The analysis of such events reveals that the energetic particles are confined and accelerated to higher energy by interplanetary shocks through the diffusive shock acceleration mechanism, which results in the late release of high-energy particles. This study challenges the traditional picture and opens a new window for diagnosing the remote interplanetary shock from observed IVD structure.

A new study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth’s core, by showing how it was able to crystallise millions of years ago. The study has been published today (Sept. 4) in Nature Communications.

Recent experimental findings from the research team led by Prof. Jianbo Hu at the Institute of Fluid Physics, China Academy of Engineering Physics (CAEP), revealed partial dislocation-mediated plastic flow in shock-loaded single-crystal aluminum.​​ The experiment was conducted at the PF-AR NW14A beamline of the High Energy Accelerator Research Organization (KEK). Utilizing laser ablation to generate shock waves and employing ultra-bright, ultra-short X-ray pulses from synchrotron radiation, the team captured in situ Laue diffraction patterns of single-crystal Al during dynamic loading. ​​This work provides the first experimental evidence of partial-dislocation-dominated plastic flow in shock-compressed single-crystal Al​​, enabling analysis of the distinct deformation mechanisms between quasi-static and dynamic loading in aluminum—a high stacking fault energy metal. ​​These findings offer new insights into the plastic deformation of aluminum under high strain rates and establish novel theoretical and experimental foundations for multi-scale research on material performance under extreme conditions.​Recent experimental findings from the research team led by Prof. Jianbo Hu at the Institute of Fluid Physics, China Academy of Engineering Physics (CAEP), revealed partial dislocation-mediated plastic flow in shock-loaded single-crystal aluminum.​​ The experiment was conducted at the PF-AR NW14A beamline of the High Energy Accelerator Research Organization (KEK).

This study achieved the controllable generation of the Z phase in P2-type layered oxides through the Al substitution strategy, revealing the mechanism by which flexible Al-O bonds suppress irreversible phase transitions and stabilize local structures. This provides new insights into addressing the structural degradation issues caused by lattice oxygen redox.

Researchers at the University of Missouri are working to make hydrogen energy as safe as possible.
