“…The nature of the polymer material is a key factor in determining the quality of the microspheres. PS and PAMS microspheres are commonly available as ICF polymeric microspheres, [17][18][19][20][21][22][23] but little systematic discussion has been done as to make materials more suitable for the preparation of thin-walled polymer microspheres for ICF experiments. Based on this background, we investigated the effects of PS and PAMS on the sphericity, wall thickness uniformity, surface topography, thermal properties, and cracking yield of thin-walled polymer hollow microspheres.…”

Polymer microspheres can be used as fuel containers for laser inertial confinement fusion (ICF) due to their low atomic number, low density, and high thermal stability. The thin-walled polymer microspheres are prone to cracking due to an increase in the diameter to thickness ratio (diameter/wall thickness).The effect of polystyrene (PS) and Poly (α-methyl styrene) (PAMS) materials commonly used in ICF experiments on the quality of thin-walled microspheres is investigated. PS hollow microspheres show better sphericity, smoother surface, and lower cracking rate than PAMS microspheres. Moreover, the heat treatment of solidified PS microspheres can improve the strength so that the cracking rate of the microspheres decreases. The relative mechanism of how the molecular structure affect the quality is also discussed. This study provides some guidance for the preparation of thin-walled polymer microspheres with high quality for ICF experiments.

Microfluidic droplets, with their unique properties and broad applications, are essential in in chemical, biological, and materials synthesis research. Despite the flourishing studies on artificial intelligence‐accelerated microfluidics, most research efforts have focused on the upstream design phase of microfluidic systems. Generating user‐desired microfluidic droplets still remains laborious, inefficient, and time‐consuming. To address the long‐standing challenges associated with the accurate and efficient identification, sorting, and analysis of the morphology and generation rate of single and double emulsion droplets, a novel machine vision approach utilizing the deformable detection transformer (DETR) algorithm is proposed. This method enables rapid and precise detection (detection relative error < 4% and precision > 94%) across various scales and scenarios, including real‐world and simulated environments. Microfluidic droplets identification and analysis (MDIA), a web‐based tool powered by Deformable DETR, which supports transfer learning to enhance accuracy in specific user scenarios is developed. MDIA characterizes droplets by diameter, number, frequency, and other parameters. As more training data are added by other users, MDIA's capability and universality expand, contributing to a comprehensive database for droplet microfluidics. The work highlights the potential of artificial intelligence in advancing microfluidic droplet regulation, fabrication, label‐free sorting, and analysis, accelerating biochemical sciences and materials synthesis engineering.
