The improper use of chemical pesticides threatens ecosystems and human health, highlighting the need for sustainable alternatives. Nano-pesticides and biological control agents offer a solution, and their combination can reduce pesticide usage and improve pest control efficacy. This study utilized a star polycation (SPc) to prepare a metaflumizone nano-pesticide and combined it with the egg parasitoid (Telenomus remus) for synergistic pest management.

Volatile organic compounds (VOCs) significantly impact air quality as photochemical smog precursors and health hazards. Catalytic oxidation is a leading VOC abatement method but suffers from catalyst deactivation due to metal sintering and competitive adsorption in complex mixtures. Strong metal-support interactions (SMSIs) provide atomic level control of interfacial electronic and geometric structures.

Nanocrystals (NCs), nano-sized drug particles, offer a promising strategy to enhance the bioavailability of poorly soluble compounds, a challenge that affects 70-90 % of new chemical entities. Among the available production methods, wet media milling is widely adopted due to its scalability and efficiency. However, conventional lab-scale mills often require large suspension volumes and high amounts of drug, limiting their suitability for early-stage development, particularly with novel or scarce compounds.

This study addresses critical technical challenges in fabricating functional pigmented skin models via 3D bioprinting through the synergistic integration of droplet-based deposition and precision motion control. A hybrid bioprinting strategy was developed to create multilayer biomimetic architectures: the dermal layer was fabricated through extrusion of gelatin methacryloyl-polyacrylamide (GelMA-PAM) composites, while the epidermal layer incorporated precisely patterned melanocyte-laden GelMA-PAM arrays deposited via microvalve technology, subsequently solidified and populated with keratinocytes. To enhance printing reliability, a fractional-order proportional-integral control system optimized through particle swarm optimization (PSO-FOPI) was implemented, significantly improving motor speed regulation and positioning accuracy.

Electrochemical CO reduction (CORR) to carbon monoxide (CO) offers a sustainable pathway for carbon utilization, yet challenges remain in terms of improving selectivity and activity. Herein, we report a Ni/NC catalyst synthesized via a milling - pyrolysis method, in which Ni particles anchored on nitrogen-doped carbon (NC) are electrochemically activated under an Ar atmosphere, leading to their structural evolution into single-atom Ni sites. After activation in Ar atmosphere, the current density nearly doubles (from ≈30 to ≈60 mA cm), and concurrently, the Faradaic efficiency of CO stays at ∼90% with the potential set to -0.
