Abstract This paper introduces a novel, ecofriendly, and cost‐effective method to create deformation patterns on vertically vibrating thin film surfaces using resonant sessile droplets. The key findings emphasize the critical role of frequency vibration velocity in formation these deformations. Through theoretical experimental investigations aluminum film, it is validated that deformations are influenced by energy distribution within Specifically, higher‐order frequencies produce more concentrated at droplet's center due internal top‐down flow behaviors, resulting various states. By observing regularities width patterns, underlying phenomena elucidated, derive related empirical formulas. demonstrates significant potential for surface microstructure fabrication. ability control shapes adjusting parameters crucial optimizing microfabrication processes.

Quantum dots (QDs) are vital for virtual reality and augmented displays due to their tunable optical properties. Although QD color converters enable blue light-emitting diode down-conversion green/red, efficiency stability issues hinder high-end display applications. Here, we employ a cross-linking-assisted hierarchical confined assembly method fabricate red, green, arrays. Specifically, micropillar templates with asymmetric wettability used sequentially deposit green red microwire arrays in mutually orthogonal directions on film, forming RGB 4,4′-Bis(3-vinyl-9H-carbazol-9-yl)1,1′-biphenyl (CBP-V) is introduced into QDs solve the problem of crosstalk. Full-color pixel resolutions 1814–2117 pixels per inch (PPI) successfully fabricated. Upon integration devices, adjustable emission from cool white light warm observed, peak external quantum (EQE) 16.14% luminance 226 054 cd m–2.

Halide vacancies on the surfaces of cesium lead halide perovskite (CsPbX3, X = Cl, Br, or I) nanocrystals (NCs) play a crucial role in their photoluminescence quantum yield (PLQY) and photostability. However, effectively passivating these remains challenge. Here, 2-bromohexadecanoic acid (BHA) is introduced as bidentate auxiliary ligand for CsPbX3 NCs. The CsPbBr3 CsPbBr1.5I1.5 NCs, comodified with BHA, oleic (OA), oleylamine (OLA) 20% OA substituted by are synthesized using hot-injection technique designated BHA-CsPbBr3 BHA-CsPbBr1.5I1.5 NCs exhibit PLQY 97% retain 42.19% original intensity after 48 h continuous ultraviolet light exposure. (PL) properties, stability, PL recombination mechanism investigated detail. It believed that carboxyl oxygen ortho-bromine atoms enhance binding strength BHA to surface CsPbX3. Additionally, Br- ions produced from biomolecular nucleophilic substitution reaction between OLA partially occupy anionic These interactions reduce performance

Abstract Electrohydrodynamic (EHD) jet printing represents a novel micro/nano-scale additive manufacturing process that utilises high-voltage induced electric field between the nozzle and substrate to print micro/nanoscale structures. EHD is particularly advantageous for fabrication on flexible or non-flat substrates of large aspect ratio micro/nanostructures composite multi-material Despite this, has yet be fully industrialised due its low throughput, which primarily caused by limitations serial technology. The parallel multi-nozzle array-based become most promising option achieve large-scale increasing number nozzles realise multichannel printing. This paper reviews recent development technology, analyses motion with multi-nozzle, explains origins crosstalk effect under discusses several widely used methods overcoming it. work also summarises impact different parameters describes current using as well method they can realised independently. In addition, it presents an additional significant utilisation aside from enhancing single-nozzle production efficiency, phase change materials through multi-nozzle. Finally, future direction discussed envisioned.
