Light fastness of liquid crystal-based thermochromic printing inks

Errors in thermochromic liquid crystal thermometry

This article experimentally investigates and assesses the errors that may be incurred in the hue-based thermochromic liquid crystal thermochromic liquid crystal (TLC) method, and their causes. The errors include response time, hysteresis, aging, surrounding illumination disturbance, direct illumination and viewing angle, amount of light into the camera, TLC thickness, digital resolution of the ...

Ink-Jet Printing Cotton with Cationic Reactive Dye Based Inks

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

3d-printing of Energy Devices Using Particle-based Inks

Introduction and Summary Over the past year, ISEN funding has been utilized to make significant research progress towards the fabrication of a fully 3D-printed iron/solid oxide fuel cell (Metallic/multi-ceramic) batterygenerator system (Figure 1). Monies have gone towards the partial funding of one grad student/postdoc, Adam Jakus, in Ramille Shah’s Tissue Engineering and Additive Manufacturing...

Inkjet Printing onto Liquid Crystal Thin Films

Stamping oriented molecular monolayers using liquid crystal inks.

Thermotropic liquid crystal (LC)-based inks are combined with patterned anchoring stamps to deposit organic monolayer films with simultaneous control over positional and molecular orientational order in a single step.
