Centrifugal spinning is a new technique for producing of nano and microfibers that has great differential: higher production rate than those presented by traditional methods. Due to interest in using technological applications along with the environmental polymer recycling, this research had purpose fibers centrifugal from expanded poly-styrene recycling evaluation influence operational paramet...

abstract: Ultra-high performance concretes with steel microfibers have been studied in depth the aim of producing more efficient and durable structures. The these materials depends on characteristics interface between cementitious matrix. This research investigates micro-nanomechanical properties interfacial transition zone matrix ultra-high composite. effect water/cement ratio distance from mi...

A novel type of polarization converters (PCs) based on highly birefringent (Hi-Bi) microfibers is presented. Analytical formulation based on the Jones Matrix method and a numerical code based on the Full Vectorial Finite Difference Beam Propagation Method are developed to analyze the polarization evolutions in such PCs. Two different design configurations, namely the "one-side" and "two-side" p...

We demonstrate spatially controlled photoreactions within bicompartmental microparticles and microfibers. Selective photoreactions are achieved by anisotropic incorporation of photocrosslinkable poly(vinyl cinnamate) in one compartment of either colloids or microfibers. Prior to photoreaction, bicompartmental particles, and fibers were prepared by EHD co-jetting of two compositionally distinct ...

Engineering three-dimensional (3D) scaffolds with in vivo like architecture and function has shown great potential for tissue regeneration. Here we developed a facile microfluidic-based strategy for the continuous fabrication of cell-laden microfibers with hierarchically organized architecture. We show that photolithographically fabricated microfluidic devices offer a simple and reliable way to...
