Increasing global demand for food presents a significant challenge to maintaining soil health and sustainable production of agricultural crops. As plant root-associated microbial fitness is greatly impacted by community growth, development, and nutrient acquisition, the cultivation of functional assembly of root-associated microbes may provide solutions for achieving food security while maintaining healthy soils. Here, we propose a four-part strategy to promote soil health and agricultural productivity by partnering crops with root-associated microbes.

With distinct advantages such as high gravimetric and volumetric capacity(5855 mAh·cm-3and 820mAh·g-1), low redox potential(-0.762 V vs. standard hydrogen electrode（SHE）), high abundance, low toxicity and intrinsic safety of Zn metal anode, Zn-ion batteries have become a potential alternative to Li-ion ***, several challenges still need to be addressed prior to the practical applications of Zn-ion batteries, such as dendrite growth during Zn plating/stripping and interfacial side reactions on the Zn surface. Such issues can be addressed by introducing additives to regulate the components and structures of the electrolyte. In this review, we systematically discussed the core issues of metallic Zn anodes and comprehensively summarized a novel perspective of the regulation mechanism of inhibiting dendrite growth or interfacial side reactions in Zn anodes by introducing additives into aqueous ***, some discussions and prospects for aqueous Zn ion batteries（AZIBs） are presented for future research.

Microlens arrays have been widely used in the fields of micro-optics and micro-and nanofabrication. Traditional preparation methods utilize commercial photoresists and thermosetting materials, thereby restricting the optical properties of microlenses. In recent years, significant advancements have been achieved in near-field super-resolution imaging by utilizing microspheres and forming arrays of microsphere lenses via self-assembly. However, self-assembly approaches lack flexibility in terms of pattern selection. This study proposes a method that utilizes electrohydrodynamic jet (E-jet) printing to code ultraviolet (UV)-curable adhesives and assist in the assembly of patterned microsphere-lens arrays. Simulation results demonstrate that the UV-curable adhesive has little impact on the optical properties of the microsphere lens. Moreover, the microsphere lens exhibits a superior imaging resolution compared with traditional microlenses. A projection-lithography system is developed to achieve an accurate alignment between the focal plane of the microsphere lenses and the plane of the photoresist, facilitating the fabrication of patterned nanostructures. The lithographic nanostructures have a minimum feature size of 850 nm. This method enables the fabrication of arrays of microsphere lenses with arbitrary patterns and presents an inexpensive and simple strategy for fabricating micro-and nanostructure arrays with submicrometer features.
