Summary: Electrochemical nitrogen reduction reaction (NRR) in ambient condition allows for sustainable large-scale NH3 production. However, developing effective and durable NRR catalysts to enhance NH3 synthesis rate and Faraday efficiency remains challenging due to the inertness of the N equivalent to N bond. In this study, porous NiBi catalysts with abundant active sites were prepared through chemical dealloying. The synergistic effect of Ni and NiBi was found to enhance N2 adsorption, inhibit competing reactions, and reduce the free energy of intermediates (*NNH). Porous Ni91.5Bi8.5 exhibited high catalytic activity for NH3 formation with a yield of 18.35 mu g h-1 mg-1 and a Faraday efficiency of 51.12% at -0.3 V vs. RHE, surpassing most reported NRR electrocatalysts under ambient conditions. This strategy represents an effective and universal technique for synthesizing catalysts with great potential in energy conversion applications.

Summary: The rapid development of sonodynamic therapy (SDT) provides a promising strategy for treating deep-seated multidrug-resistant (MDR) bacterial infection. However, the scarcity of biologically functional and efficient sonosensitizers limits the clinical practice of SDT. In this research, lattice-strain-rich Ti3C2 (LS-Ti3C2) was synthesized using Ti3C2 and meso-tetra(4-carboxyphenyl)-porphine (TCPP) to achieve extraordinary SDT. The intervention of TCPP caused structural distortion of Ti3C2, resulting in narrowed band gap and enhanced electron-hole pair separation under ultrasound irradiation, leading to US-mediated reactive oxygen species (ROS) production and robust bactericidal capability against MRSA. This research offers a perspective into the development of Ti-familial sonosensitizers for SDT practice.

Summary: This article discusses the isochronal creep recovery of a Zr-based material by constructing a dynamic viscoelastic model based on the Maxwell model, taking into account structural heterogeneity and relaxation effects. The study reveals that creep strain retention occurs when elastically deformed and plastically deformed regions coexist, and that residual creep strain is released when relaxation is activated sequentially. The temperature and time of stress-annealing treatment affect the creep strain recovery magnitude and peak temperature, while the stress-annealing stress only affects the recovery magnitude.
