Continuous spheroidization strategy for explosives with micro/nano hierarchical structure by coupling microfluidics and spray drying

Coupling Oscillating–Swirling–Coflowing: A Microfluidic Strategy for Superior Safety and Output Performance of Core–Shell Energetic Microspheres

“…What determines whether we choose a single-chamber or double-chamber micromixer is the residence times in micromixer. According to our previous work, 27,30 the minimum residence times of EMs in the micromixers are 333.3 and 392.0 ms, respectively. The volumes of one-chamber and doublechamber micromixers are about 0.11 and 0.16 mL.…”

“…However, this strategy is still limited in the field of materials modification. Microfluidics modulates fluids in microscale channels and has broad applications in the design and implementation of high-quality materials. − From the needs of core–shell modification and continuous spheroidization, it can be seen that coupling oscillating–swirling–coflowing microfluidics will provide new opportunities for the design and creation of microspheres with superior core–shell structures via spray-drying. − …”

“…Previous work laid the foundation for a continuous microfluidic platform, but there are many gaps in the design and preparation of superior core–shell energetic microspheres. This study is divided into three parts: model establishment, experimental verification, and performance characterization.…”

Fabrication of syntactic foam fillers via integrated on/off-chip microfluidic methods for optimized geopolymer composites

“…In recent years, droplet microfluidics, emerging as a multidisciplinary scientific technique, featured by miniaturization, high throughput, and precision, trace amount of material consumption, has aroused the research enthusiasm of numerous scholars worldwide. 24–26 The droplet and fiber templates with delicate configurations can be readily prepared through multiphase fluids manipulation, which possesses prominent advantages of high uniformity, flexibility, and controllability, and can serve as the prototype to fabricate SFFs. 27–29 Lee introduced bubbles as templates to make SFFs with consistent outer diameter but varying mechanical properties, which is attributed to the discrepancy of shell thickness that derives from the autonomous floating of the inner bubble.…”
