Production of Parallel Aligned Nanofiber Rovings From Continuous Bundles

Advanced Materials Technologies, EarlyView.
Continuous nanofiber rovings are produced via electrospinning. The integration of false twisting and drawing improved fiber properties. Optimized twisting increases fiber alignment and tensile strength. The drawing process reduces the average nanofiber diameter from 297 to 200 nm and decreases the standard deviation of alignment angles from 14.2° to 8 ...

Visual suppression of the vestibulo-ocular reflex during space flight [PDF]

Visual suppression of the vestibulo-ocular reflex was studied in 16 subjects on 4 Space Shuttle missions. Eye movements were recorded by electro-oculography while subjects fixated a head mounted target during active sinusoidal head oscillation at 0.3 Hz.

Aerosol Jet Printing of Superhydrophobic Surfaces

Advanced Materials Technologies, EarlyView.
A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.
