Summary: This study reports the synergy effects in promoting catalytic power in ternary transition metal Zn, Co, Ni alloy nanoparticles that embeds in the carbonized Ppy/CNT multilayered matrix. Experimental and DFT calculation results indicate that the ternary transition metal catalysts in the N-doped carbon matrix present special electronic structure, which benefits the reversible transition-state adsorption in HER and OER and render the catalysts high conductivity in room temperature. These findings contribute to the further development of efficient transition metal HER and OER catalysts.

Summary: Bimetallic catalysts have been widely used for peroxymonosulfate (PMS) activation, but the synergy between Zn and other transition metals in PMS activation is rarely studied. In this work, a Co/Zn co-doped carbonaceous catalyst derived from ZIF-67@ZIF-8 (Z67@8D) was prepared and used to activate PMS for sulfamethoxazole (SMX) degradation. The Co/Zn synergy was revealed by experiments and density functional theory (DFT) calculations, showing that Zn can adjust the electron distribution of Co and enhance PMS decomposition and singlet oxygen (O-1(2)) formation. The catalyst also demonstrated good stability, reusability, and universal applicability.

Summary: Spinel copper cobaltite (CuCo2O4), as a bifunctional oxygen electrocatalyst, has attracted significant research interest due to its tailored electronic structure and adjustability of active area. However, its poor oxygen evolution reaction (OER) performance hinders its practical use in rechargeable zinc-air batteries. Therefore, researchers have constructed a CuCo2O4/NiFe LDH oxide/hydroxide interface to enhance OER activity and reduce charging overpotential. The achieved electrocatalysts show improved OER performance, resulting in high round-trip efficiency and low voltage gap in zinc-air batteries.

Summary: By combining first-principles calculations, machine learning fitted potential, and solving the phonon Boltzmann transport equation, we propose a new group of two-dimensional covalent organic frame semiconductors 2AL-PR-X (X = 2H, Ni, Pt, Zn) as promising organic thermoelectric materials. We found that embedding metal atoms in the center can greatly enhance the stability of the porphyrin ring and reduce thermal conductivity. Among the studied 2AL-PR-X materials, 2AL-PR-Pt shows the best thermoelectric performance with a peak ZT of 0.32 at room temperature and around 0.9 at 800 K.

Summary: The study investigated the competitive sorption and transport of nickel (Ni) and zinc (Zn) in Olivier and Windsor soils. The results showed that the sorption of Ni and Zn was mutually reduced in multicomponent systems, indicating competition for sorption sites. When applied concurrently, competition increased the mobility of both ions during miscible displacement experiments. A novel CDI isotherm provided a superior description of the competitive batch data, while CDIT and SRST generally described the transport data well. The CDI/CDIT approach may be more generally applicable to multicomponent systems and warrants further study.

Summary: Electric-driven CO2 reduction is a promising strategy for converting CO2 into valuable chemicals and fuels, but finding low cost and efficient catalysts remains a challenge. In this study, a highly selective and stable layer-stacked Zn catalyst was developed for CO2 reduction to CO through an efficient and facile electrochemical method. The catalyst exhibited more than 90% Faradaic efficiency for CO production and maintained similar selectivity for more than 70 hours, surpassing the durability of previous Zn-based catalysts. The robust catalytic performance could be easily recovered through simple electrochemical methods, thanks to the maintained layer-stacked structure.

Summary: Controlling the interaction between localized spins and itinerant electrons at oxide interfaces can result in exotic magnetic states. In this study, SrTiO3/LaTiO3/SrTiO3 heterostructures with varying thickness of the LaTiO3 layer (n monolayers) were used to investigate magnetic interactions in a two-dimensional electron gas system. Significant Kondo effect was observed when the LaTiO3 layer was thin, indicating strong interaction between itinerant electrons and localized magnetic moments at the interfaces. This effect was greatly inhibited when the LaTiO3 layer was thicker. Notably, distinct Shubnikov-de Haas oscillations and a nonzero Berry phase were observed in the thinner LaTiO3 layers, but absent in the thicker one. These phenomena were interpreted as a result of subband splitting and symmetry breaking due to the interplay between interfacial Rashba spin-orbit coupling and magnetic orderings in the heterostructures. These findings provide insights into manipulating nontrivial electronic band structures at complex oxide interfaces.

Summary: In this study, researchers developed a facile carbonization coupled oxidation strategy to produce NiO clusters-decorated Ni-N-C SACs. These SACs exhibited a high Faradaic efficiency of CO and a high turnover frequency for CO production even at high overpotentials. Density functional theory calculations revealed that the highly dispersed NiO clusters played a crucial role in enhancing the reaction kinetics for CO production. This study provides a new pathway for the construction of oxygen-regulated metal-based SACs and various catalytic applications.

Summary: In this study, nanosized LaInO3 perovskite catalyst was synthesized and applied to CO2 electrocatalytic reduction reaction (CO2RR), showing excellent activity for formate production. The highest faradaic efficiency of formate reaches 91.4% and the partial current density of formate is 106.8 mA cm(-2) at a moderate overpotential of 0.9 V. Experimental research and DFT calculations indicate that the outstanding activity of LaInO3 is mainly attributed to its intensive adsorption stability to free radical intermediates (CO2 center dot-) and lower desorption free energy of formate products during reaction.

Summary: In this study, lightweight, flexible and high-performance composite foams (TPU/EG/Ag) with a three-dimensional isolated conductive network were successfully manufactured by combining supercritical carbon dioxide (scCO2) foaming and chemical deposition. The composite foam achieved high conductivity (171.2 S/m) and EMI shielding effectiveness (56.3 dB) with only 0.58 vol% Ag, thanks to the volume exclusion of pores and the selective enrichment of Ag nanoparticles. The weight reduction rate of the composite exceeded 74%, and the density of the foamed sample could be as low as 0.21 g/cm3. Interestingly, the presence of porosity not only alleviated impedance mismatch and reduced reflectivity of the composite, but also improved compressible recovery performance and shielding stability. This work proposes a new idea for lightweight and flexible EMI shielding composites, opening a new path for the development of next-generation absorption-based EMI shielding materials.
