Hierarchical Ni-Mn LDHs@CuC\u3csub\u3e2\u3c/sub\u3eO\u3csub\u3e4\u3c/sub\u3e Nanosheet Arrays-Modified Copper Mesh: A Dual-Functional Material for Enhancing Oil/Water Separation and Supercapacitors

The pursuit of superhydrophilic materials with hierarchical structures has garnered significant attention across diverse application domains. In this study, we have successfully crafted Ni-Mn LDHs@CuC2O4 nanosheet arrays on a copper mesh (CM) through a synergistic process involving chemical oxidation and hydrothermal deposition. Initially, CuC2O4 nanosheets were synthesized on the copper mesh, closely followed by the growth of Ni-Mn LDHs nanosheets, culminating in the establishment of a multi-tiered surface architecture with exceptional superhydrophilicity and remarkable underwater superoleophobicity. The resultant Ni-Mn LDHs@CuC2O4 CM membrane showcased an unparalleled amalgamation of traits, including superhydrophilicity, underwater superoleophobicity, and the ability to harness photocatalytic forces for self-cleaning actions, making it an advanced oil-water separation membrane. The membrane’s performance was impressive, manifesting in a remarkable water flux range (70 kL•m-2•h-1) and an efficient oil separation capability for both oil/water mixture and surfactant-stabilized emulsions (below 60 ppm). Moreover, the innate superhydrophilic characteristics of the membrane rendered it a prime candidate for deployment as a supercapacitor cathode material. Evidenced by a capacitance of 5080 mF•cm-2 at a current density of 6 mA cm-2 in a 6MKOH electrolyte, the membrane’s potential extended beyond oil-water separation. This work not only introduces a cutting-edge oil-water separation membrane and supercapacitor electrode but also offers a promising blueprint for the deliberate engineering of hierarchical structure arrays to cater to a spectrum of related applications

The spread of intangible cultural heritage in the rural agricultural environment of modern China under the epidemic economic environment

In the rural agricultural environment, intangible cultural heritage has proved to be a resilient and essential component of community identity and well-being, especially in the face of the challenges posed by the epidemic economic environment. The preservation and celebration of intangible cultural practices, such as traditional agricultural methods, local festivals, and folk arts, provide opportunities for community connection, pride, and economic development despite the economic recession. The current financial crisis threatens China's rural agricultural communities' intangible cultural assets and long-term viability. Using awareness (as a mediator) and access to resources (as a moderator), this study examines how the expansion of intangible cultural assets and the rural agricultural environment affects preservation and sustainability in modern China's rural agricultural environments during the economic epidemic. A simple random sampling technique was used to collect information from 430 participants. Smart-PLS was employed to assess the dependability of data and the relationship between factors. The results indicate that disseminating intangible cultural heritage and the rural agricultural environment is advantageous to preserving intangible cultural heritage and the viability of rural communities. Moreover, resource access regulates and modulates this link. According to the study, increasing awareness and providing access to resources can help rural communities preserve intangible cultural assets and nurture long-term development.Xuanyi Wu (Ph.D. candidate, Universiti Putra Malaysia, Faculty of Modern Languages and Communication), Megat Al Imran Yasin (TS.

Magnetoelectric coupling induced by interfacial orbital reconstruction

The magnetoelectric coupling effect with profound physics and enormous potential applications has provoked a great number of research activities in materials science. Here, we report that the reversible orbital reconstruction driven by ferroelectric polarization modulates the magnetic performance of ferroelectric ferromagnetic heterostructure. Mn in plane orbital occupancy and related interfacial exotic magnetic state are enhanced and weakened by the negative and positive electric field, respectively. Our findings thus not only present a broad opportunity to fill the missing member, orbital in the mechanism of magnetoelectric coupling, but also make the orbital degree of freedom straight forward to the application in microelectronic device.Comment: 26 pages, 5 figures, Accepted by Advanced Material
