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.

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip. The study, led by Carlos A. Meriles, Martin and Michele Cohen Professor of Physics in the Division of Science and entitled “Emission of Nitrogen–Vacancy Centres in Diamond Shaped by Topological Photonic Waveguide Modes,” appears in the journal Nature Nanotechnology.

Rice computer scientists have developed algorithms that account for quantum noise that is not just random, but malicious interference from an adversary.
