Summary: This paper numerically investigates the mechanisms of a charge injection-induced electrohydrodynamic pump using the lattice Boltzmann method. The pump consists of a dielectric liquid layer and two substrate layers with embedded electrodes. Three possible flow modes are found, which are associated with the generation of local convective rolls for different electrode arrangements, namely, modes associated with one and two vortices and an irrotational mode. Results for both the transient development of the flow field and the steady-state total flow rate and pressure are presented for different flow modes. A distinct four-state transition can be observed in the temporal record of the velocity field. Regarding pumping ability, it is found that the irrotational mode can lead to optimal performance, while the single-vortex flow mode gives the worst performance.

Summary: This work demonstrates the use of EHD inkjet printing to pattern luminescent nanomaterials on photonic structures. Nanoscale CsPbBr3 NC features were successfully deposited on the structures, maintaining structural integrity throughout the printing process. The deposited NCs demonstrated sub-micrometer control and cavity-emitter coupling in silicon nitride nanophotonic cavities.

Summary: We propose a universal direct photocatalytic patterning method that can preserve the optical properties of nanocrystals and other emissive nanomaterials, while enhancing the photoluminescence quantum yield and photostability of certain materials. This method has the potential to pattern various functional materials and devices in a nondestructive and simple way.

Summary: This paper reviews a recent patterning technique called electrohydrodynamic patterning (EHDP), which uses an externally applied electric field to create micro-/nano-patterns on thin polymeric films. The theoretical and numerical studies of EHDP are presented, as well as the discussion on how the characteristic wavelength and time are influenced by external conditions and polymer properties. Various strategies for fabricating high-aspect-ratio or hierarchical patterns are reviewed, with emphasis on aligning and ordering of anisotropic polymers. The paper also provides a perspective on the novelty and limitations of EHDP compared to conventional patterning techniques, and suggests possible future research directions.

Summary: In this work, the authors investigate microscale electrohydrodynamic conduction pumps of dielectric liquids and find that the electric force differs from macroscale conduction pumps due to the scale effect. The enhanced ionic diffusion in microscale pumps is identified as the trigger for the scale effect. Existing macroscale theoretical models do not work for microscale pumps due to the inaccurate estimation of heterocharge layer thickness. A new theoretical model is developed by modifying the expression of heterocharge layer thickness.

Summary: This paper reviews the development of functional fluidic and gas electrohydrodynamic (EHD) pumps, including the initial observation of the EHD effect, mathematical modeling, and the choice of pump structure, electrode configuration, and working medium. It also presents a summary of the latest research on EHD pumps and provides a critical analysis of their current limitations and potential areas for future research. The paper discusses the potential application of artificial intelligence in the field of EHD pumps and highlights the importance of soft EHD pumps, which have received less attention.

Summary: This paper presents a shrinkage-assisted patterning method for fabricating multilayer, multimaterial, and conformal electrodes. The method utilizes evaporation-induced strain mismatch to print high-resolution, patterned, and multilayer electrodes. The electrodes can auto-detach from the filtration membrane due to the mismatch between the electrode and membrane strains. The method shows potential for high-energy density micro-supercapacitors and stable digital circuits on deformed surfaces.

Summary: In this study, high resolution and high conductivity silver nanoparticle (AgNP) based inks were achieved using electrohydrodynamic (EHD) printing. By carefully controlling the parameters such as the composition of Ag ink, printing speed, voltage, and working height, the resolution was increased and the process window of the cone jet mode was established. The generation mechanism of the Taylor cone was clarified through finite element simulation. Ag electrodes with various patterns and shapes were easily produced, exhibiting excellent patterning qualities. Flexible LED circuits, transparent heaters, and supercapacitors were successfully fabricated using EHD printed Ag grid electrodes, providing a simple and scalable strategy for fabricating ordered metal conductive patterns in printed electronics.

Summary: Dispersing pentagonal gold bipyramids in nematic liquid crystals allows for narrow and controlled polarization-dependent surface plasmon resonance spectra, with easy electric switching. The bipyramids orient with their C-5 rotation symmetry axes along the nematic director, showing spatially homogeneous density in aligned samples. Topological solitons enable spatial reorganization of the nanoparticles based on elastic free energy density within their micrometer-scale structures.

By triggering local thermal stimuli with near-infrared lasers, various nanocrystals can be patterned with high resolution and nondestructive manner. This method overcomes limitations of traditional and emerging patterning techniques and holds promise for the development of advanced optoelectronic functionalities such as transparent electronics.
