Summary: To achieve better overall catalytic performance, it is necessary to minimize the potential drop and energy overhead caused by serial resistances in electrocatalytic systems. This study develops a silver nanowire (AgNW) aerogel-based support that enables highly energy-efficient catalytic systems upon catalyst loading. Through a case study of two Ni-based catalytic systems, superior performance with ultralow solution resistance and overpotential without iR compensation is achieved. Density functional calculations support the hypothesis that the support-induced hierarchical nanostructures enhance hydrogen adsorption sites, conductivity, and HER activity. This work opens up the possibility of developing highly efficient catalytic systems using NW-based supports.

Summary: Substrate-independent and robust coatings with desired functions are in high demand, but their fabrication and fundamental theory remain challenging due to conflicting requirements on surface free energy (SFE) at different interfaces. A novel strategy based on counterion exchange has been developed to tailor SFE continuously and reversibly. PVDF-g-IL coating with hierarchical surface roughness was fabricated and exhibited excellent bondability and robustness. Controlled counterion exchange was used to tune SFE at the top interface, enabling super-hydrophilic/super-hydrophobic properties and tunable adsorption at multiple interfaces.

Summary: In this study, a series of stainless steel thin films were fabricated by DC power magnetron sputtering at various argon working pressures. The films exhibited a single phase, body-centered cubic ferrite crystal structure, with a textured surface morphology composed of nano-sized pyramids at pressures of 6 mTorr and above. As the argon pressure increased, the microstructural evolution from dense, fibrous grains to coarse tapered grains was observed, leading to a significant reduction in static water contact angle.

Summary: This article explores the wide application prospects of surface wettability in energy harvesting, conversion, and emission control technology, focusing on the recent interest in altering surface wettability through nanomaterial fabrication and coating. Surface properties such as roughness, surface energy, porosity, capillarity, and structure play a major role in changing the wettability of liquids over surfaces, with surface chemistry being a key factor in inducing wettability alteration. Surface pre- and post-treatments like laser, ozone plasma, and UV irradiation contribute to changes in surface energy, leading to superhydrophilicity and superhydrophobicity.

Summary: A mechanically tunable broadband terahertz modulator based on high-aligned Ni nanowire arrays was proposed, demonstrating effective modulation of THz wave transmittance through mechanical stretching. The modulation depth showed a linear relationship with strain, ranging from 0 to 85% in the frequency range of 0.3 THz to 1.8 THz, with detectable modulation depth of about 15% for a 1% strain change resolution. This flexible Ni NW-based modulator has potential applications in remote strain sensing and wearable devices.

Summary: Inactivation of bioaerosols is crucial in preventing the spread of microbial pathogens in the air. Traditional photocatalytic inactivation processes are time-consuming and generate insufficient reactive oxygen species (ROSs) to irreversibly inactivate bacteria. A new photocatalytic ozonation (PCO) system was developed in this study, utilizing NiFeOOH nanosheets on nickel foam and trace concentration of ozone. The PCO system demonstrated a remarkable inactivation efficiency of 99.99% within a short retention time of 8.07 s, with no bacteria surviving after 24 h cultivation. This novel PCO system offers a more efficient method for bioaerosol inactivation and reduces the risk of exposure.

Summary: Exploring the interactions among doping heteroatom, carbon and metal atoms can significantly enhance the catalytic performance and gain an insightful understanding of the heterogeneous catalysis mechanism. The N,P co-doped carbon-coated cobalt (Co@NPC) catalyst exhibits high selectivity and water-durability in aqueous-phase hydrogenation of cinnamaldehyde, with precise control of products by adjusting N and P doping. The synergy of geometry and electrons in Co@NPC di-heteroatoms allows for selective reduction of C=O, while Co@NC without P doping shows high activity but significant productivity of saturated alcohols under equivalent conditions. The electronegativity difference among N, C and P atoms enables interaction between electrons, adjusting the chemical states of the active metal and enhancing catalytic performance in hydrogenation.

Summary: Enzymes, as exceptional natural catalysts, play vital roles in life-sustaining biotransformations due to their exquisite 3D structures. However, their flexibility makes them vulnerable in non-physiological environments, hindering their large-scale industrial applications. This study presents a new bottom-up strategy for enzyme encapsulation using a hydrogen-bonded organic framework (HOF-101), allowing for the encapsulation of various enzymes within a highly crystalline scaffold. Compared to other methods, this enzyme-triggering HOF-101 encapsulation is easy to operate and offers higher loading efficiency, with a well-arranged structure and mesochannels that enhance mass transfer and understanding of biocatalytic processes.

Summary: This contribution comprehensively investigates the biomineralization of zeolite imidazole frameworks for one-step synthesis of an enzyme-MOF biocomposite. The study reveals that the biomineralization ability depends on the ZIF organic linker, and the biocatalytic function is highly related to the ZIF mineral species and their microstructures. Additionally, the protective effect of ZIF mineral on the hosted enzyme is associated with the synergistic effect of size dimension and chemical microenvironment of the ZIF pores.
