As perovskite quantum dots (PeQDs) are performing their outstanding characteristics, incremental efforts have been devoted to such materials. Here, inspired by the spider spinning process, we present novel PeQDs microfibers with tailorable morphologies and functions from a multi-injection microfluidic approach. The were generated introducing precursors into each barrel of inner capillary array ...

In this paper, we introduce a novel cylindrical channel that generates coaxial flow without using glass microcapillary or complicated silicon processing, and we demonstrate the fabrication of microparticles and microfibers using this channel. The simple fabrication process for cylindrical channels employs the deflection of free-standing thin PDMS membranes. Using this channel, alginate micropar...

Native bone extracellular matrix (ECM) is a complex hierarchical fibrous composite structure, resulting from the assembling of collagen fibrils at several length scales, ranging from the macro to the nanoscale. The combination of nanofibers within microfibers after conventional reinforcement methodologies seems to be a feasible solution to the rational design of highly functional synthetic ECM ...

We present a method based on a microfluidic chip that produces continuous jetting of alginate microfiber in the atmosphere to facilitate its collection and assembly. Through the analysis of the factors influencing the microfiber jetting, the principle and some microfluidic chip design criteria are discussed. A special nozzle is designed near the chip outlet, and deionized water is introduced in...

Abstract Background Microplastic pollution has become a serious global environmental threat. The abundance of microplastics in the air is an order magnitude higher than that other media, which means all living animals breathing with lungs (including humans) cannot escape fate inhaling microplastics. However, there no direct evidence to demonstrate what type and exist lung tissue. In addition, w...

HIGHLIGHTS The contamination of blanks by airborne fibers in the lab was investigated. Microfibers could be overestimated fish’s gastrointestinal tract and surface water. We tested approved an Airborne Contamination Control Protocol (ACC Protocol).
