Particle-like beads and daughter jet cascades in electrospinning

Cumulant versus jet-like three-particle correlations

Analysis Method for Jet-Like Three-Particle Azimuthal Correlations

Jet-like three-particle azimuthal correlations can discriminate various physical scenarios that have been proposed to explain the observed strong modification to twoparticle azimuthal correlations. The three-particle correlation analysis is notoriously difficult in heavy-ion collisions due to the large combinatorial backgrounds. We describe the general idea behind the jet-like three-particle az...

Electrospinning: A whipping fluid jet generates submicron polymer fibers

Polymeric fibers with diameters in the range from 50 nm to 5 mm are produced by accelerating a fluid jet in an electric field, in a process known as ‘‘electrospinning.’’ Here we show that an essential element of the process is a fluid instability, the rapidly whipping jet. The phenomena responsible for the onset of whipping are revealed by a linear instability analysis that describes the jet be...

like mother, like daughter? dietary and non-dietary bone fracture risk factors in mothers and their daughters

background : the aim of this study was to demonstrate similarities and differences between mothers and daughters regarding dietary and non-dietary risk factors for bone fractures and osteoporosis. methods : the study was carried out in 2007-2010 on 712 mothers (29-59 years) and daughters (12-21 years) family pairs. in the sub-sample (170 family pairs) bone mineral density (bmd) was measured for...

A comparative study of jet formation and nanofiber alignment in electrospinning and electrocentrifugal spinning systems

Electrocentrifugal spinning is a recently developed spinning system whose performance is still under investigation by researchers. In this study the process of jet formation in electrocentrifugal spinning is explored and compared to the same process in electrospinning and centrifuge spinning. The results show that the incorporation of the electrical and the centrifugal forces in the electrocent...
