Abstract Pesticide spraying serves as a prevalent segment in crop production for substantial economic and ecological benefits. Nevertheless, the existing pesticide formulations are often plagued by droplets rebounding during process, controlled‐release, photolysis protection, non‐targeted bio‐friendliness not inadequately considered. Herein, combining spinosad (SSD, model pesticide) with glycyrrhizic acid (GL) an attractive building block, supramolecular co‐assembly strategy is employed to elaborate (GL‐SSD) simultaneously featuring high deposition, environmental friendliness. The resulting spherical GL‐SSD nanoparticles (NPs) have average diameter of 207 nm show improved 5.2‐fold photostability compared commercial suspension (SSD SC). Upon impacting on hydrophobic surfaces polytetrafluoroethylene film cabbage leaf, NPs exhibit superior affinity micro/nano structure surface. Consequently, droplet inhibited effectively, ensuring deposition efficiency surfaces. In addition, release SSD from can be controlled pH variation. Indoor toxicity pot experiments demonstrate that possess good control efficacy against Plutella xylostella . work offers alternative approach development multi‐functional sustainable promising potentials actual agriculture production.

A Review on Self‐Assembly of Colloidal Nanoparticles into Clusters, Patterns, and Films: Emerging Synthesis Techniques and Applications

Small Methods, Год журнала: 2023, Номер 7(6)

Опубликована: Март 1, 2023

Abstract The colloidal synthesis of functional nanoparticles has gained tremendous scientific attention in the last decades. In parallel to these advancements, another rapidly growing area is self‐assembly or self‐organization nanoparticles. First, organization into ordered structures important for obtaining interfaces that extend even amplify intrinsic properties constituting at a larger scale. large‐scale using complex intricately designed nanostructures as building blocks, requires highly controllable techniques down nanoscale. certain cases, example, when dealing with plasmonic nanoparticles, assembly further enhances their by coupling phenomena. other process itself useful final application such sensing and drug delivery, amongst others. view importance this field, review provides comprehensive overview recent developments field nanoparticle applications. For clarity, self‐assembled are classified two broad categories: finite clusters/patterns, infinite films. Different state‐of‐the‐art obtain discussed detail, before discussing applications where significantly performance process.

Inorganic Chemistry, Год журнала: 2025, Номер 64(1), С. 452 - 459

Опубликована: Янв. 3, 2025

Icosahedral gold clusters with high-symmetry geometry and magic electronic shells are potential candidates for cluster-assembling, while their assembling rules still awaiting further investigation. In this work, we use the all-metal icosahedral M@Au12 as a building block to assemble series of bi-, tri-, tetra-, penta-superatomic molecules diverse superatomic bonding patterns via face-fusion, aiming systemically explore rule superatoms. Chemical analyses indicate that these [M@Au12]n+/0 (M = Re, W, Ta, Ti, Hf, Ir, Pt) can be considered analogues Cl2, O2, N2, CO, O3, CO2, NCl3, CF4 single, double, triple, multicenter bonds, respectively. multi-superatomic molecules, central superatom undergoes super S–P orbital hybridizations form σ bonds each peripheral superatom, mimicking molecules. Due large size superatoms, also present some distinct characters in structure relative energy compared analogues. This paper investigated rules, giving references design synthesis superatom-assembled materials.
