Summary: This study reports the formation of a unique, hierarchical, three-level pore structure through the processes of electroplating and dealloying. The co-deposition of Cu-Mn allows the formation of Cu-rich and Mn-rich regions. By removing Mn and its oxides through dealloying, Cu with a multi-porous structure is formed. The interconnected pore networks are proposed to be formed due to the growth of Cu and the rapid depletion of Cu ions during electroplating. This pore structure provides a large surface area and open pore structure, making it significant for future applications in functional chemistry and electrochemistry.

Summary: The microstructural characteristic evolution during thermomechanical processing of Ti-29Nb-9Ta-10Zr alloy was investigated. The alloy underwent multiple rolling processes, and the microstructural evolution occurred with increasing thickness reduction. The experimental results showed that finer grain size could be achieved by adjusting the heat treatment conditions. Two phases were observed through X-ray diffraction and SEM techniques, and the parameters and dimensions of the crystallites, as well as the micro-deformations at the crystalline network level, were determined. The β-Ti phase underwent refinement during the rolling processes, resulting in ultrafine/nano grain size, but its growth rate was slow during recrystallization and aging treatments.

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.

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.

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.

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: 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.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: This study presents a new approach to studying the mechanism of filiform corrosion in organic coated steel using the scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM). The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.
