OASIS Liquid Crystal Facility
Short Name:The short name or acronym of the facility. OASIS LCF
Facility Description
The Observation and Analysis of Smectic Islands in Space (OASIS) Liquid Crystal Facility (LCF) allows researchers to study liquid crystal structures and dynamics in microgravityThe condition of perceived weightlessness created when an object is in free fall, for example when an object is in orbital motion. Microgravity alters many observable phenomena within the physical and life sciences, allowing scientists to study things in ways not possible on Earth. The International Space Station provides access to a persistent microgravity environment.. The hardware enables researchers to control the ambient temperature (0-90 °C), electric field (90 V, 0-10 kHz), magnetic field (0-100 G, 0-1000 Hz), chamber pressure (0-300 kPa), droplet dispensing rate (0-1000 drops/sec), and sample concentration. Diagnostics include microscopic video (30 fps) and environmental sensor data. OASIS LCF is operated in the Microgravity Sciences Glovebox (MSG).
OASIS LCF has been used to study liquid crystal nucleation and growth, the kinetics of gelation phase separation, the structure and dynamics of many different and new composites of liquid crystal materials, the self-assembly of colloidal disks under an applied electric field, ferromagnetic fluid phases, and crystallization of magnetic nano-plates in colloidal suspensions.

iss047e004376 (3/11/2016) --- A view during the installation and configuration of the Observation and Analysis of Smectic Islands in Space (OASIS) hardware into the Microgravity, in the U.S. Laboratory. OASIS studies the unique behavior of liquid crystals in microgravity, including their overall motion and the merging of crystal layers known as smectic islands. Liquid crystals are used for display screens in televisions and clocks and they also occur in soaps and in cell membranes. The experiment allows detailed studies of the behavior of these structures and how microgravity affects their unique ability to act like both a liquid and a solid crystal.
