A new Mg-Cu system has been developed to fabricate monolithic nanoporous copper (NPC) ribbons and bulk NPC through chemical dealloying in a 5 wt.% HCl solution. The microstructures of the NPC ribbons were characterized using X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis. The results show that the compositions of the melt-spun Mg-Cu alloys have an important effect on the dealloying process and microstructures of the NPC ribbons. Moreover, the synergetic dealloying of Mg2Cu and MgCu2 in two-phase Mg-Cu alloys results in the formation of NPC with a uniform porous structure. (C) 2009 Elsevier Ltd. All rights reserved.

Formalism of rotating-wave approximation in high-spin system with quadrupole interaction

Wen-Kui Ding, Xiao-Guang Wang

Summary: We investigate the application of rotating wave approximation in a high-spin quantum system driven by a linearly polarized alternating magnetic field in the presence of quadrupole interactions. The conventional method assumes dynamics restricted to the reduced Hilbert space, but leakage from the target resonance subspace becomes significant in a multi-level quantum system when the driving strength is strong or off resonant. We propose a correct formalism that considers this leakage and applies the rotating wave approximation in the full Hilbert space, showing great advantages over the conventional method.

One-shot coherence distillation in superconducting circuit systems

Shaojie Xiong, Rui Zhang, Bo Liu, Wangjun Lu, Zhe Sun, Xiaoguang Wang

Summary: Distilling quantum coherence is essential for optimizing quantum technologies, but it is not always guaranteed. Thus, probabilistic distillation of quantum coherence has been developed and successfully implemented. We propose a scheme to achieve one-shot coherence distillation in a superconducting circuit system. By using appropriate incoherent operations, the target maximally coherent state can be extracted from a single prepared state with a finite error tolerance. Our scheme is easy to implement in experiments, requiring only a superconducting qubit as the auxiliary system. Numerical simulations under typical experimental conditions show that the distillation rate of coherence resource can be well achieved with current techniques.

Karst genesis and wormhole formation in carbonate joint networks: A comparison between 3D and 2D modeling

Chuanyin Jiang, Xiaoguang Wang, Shengyan Pu, Herve Jourde

Summary: Accurate modeling of karst genesis in carbonate rocks is crucial for understanding transport properties. Previous modeling focused on simplified 2D networks, neglecting wormhole formation on the scale of individual conduits. This study used a 3D discrete fracture network model to simulate karst genesis and wormhole formation in carbonate joint networks. The results showed that the breakthrough time in 3D models was less sensitive to network connectivity compared to 2D models due to flow focusing during wormhole formation. The dimensions and characteristics of dissolving networks were also altered when transitioning from 2D to 3D modeling. This study highlights the importance of considering the third dimension in accurate predictions of karst network evolution.

Nanoporous NiBi catalyst for efficient electrochemical N2 fixation

Wei Li, Zizai Ma, Kai Liu, Shiwei Wei, Yining Ban, Xiaoguang Wang

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.

Shiwei Wei, Xiaoyang Deng, Wei Li, Kai Liu, Jianxing Wang, Heming Zhao, Xiaoguang Wang

Summary: N-doped porous carbon nanosheets (NPCS) were synthesized using a facile recyclable molten salt strategy and low-cost coal tar pitch as the precursor. The NPCS exhibited a continuous conductive network with a high nitrogen content, enabling efficient migration of electrons and ions during sodium ion insertion/de-insertion. The NPCS demonstrated a high reversible capacity and excellent rate capability in sodium-ion half cells, as well as in a full cell using a Na3V2(PO4)3 cathode. The use of coal tar pitch via an eco-friendly approach holds promise for the development of high-performance electrodes in sodium ion electrochemical storage technology.
