BICONTINUOUS INTERFACIALLY JAMMED EMULSION GELS (BIJELS) ARE A NEW CLASS OF SOFT MATERIALS WITH INTERPENETRATING CO-CONTINUOUS ARRANGEMENT OF TWO IMMISCIBLE LIQUID PHASES SEPARATED BY A MONOLAYER OF COLLOIDAL PARTICLES. BECAUSE OF THIS UNIQUE MORPHOLOGY BIJELS OFFER SIGNIFICANT POTENTIAL FOR THE DESIGN AND SYNTHESIS OF COMPOSITE MATERIALS WITH CO-CONTINUOUS MICROSTRUCTURE FOR ENERGY AND HUMAN HEALTH APPLICATIONS WITH INITIAL EFFORTS ALONG THIS REALM ALREADY UNDERWAY. TO REALIZE THEIR FULL TECHNOLOGICAL UTILITY A MORE THOROUGH UNDERSTANDING OF THE PHYSICOCHEMICAL AND MORPHOLOGICAL FACTORS THAT INFLUENCE THE MECHANICAL STABILITY AND PROCESSABILITY OF BIJELS IS REQUIRED. HOWEVER THESE MATERIALS ARE INHERENTLY COMPRISED OF MULTIPLE PHASES WITH DISPARATE DENSITIES AND COMPLEX INTERFACIAL INTERACTIONS LEADING TO COMPLICATED PHYSICS DURING THEIR PROCESSING ESPECIALLY IN THE PRESENCE OF GRAVITY. IN FACT GROUNDBASED EXPERIMENTS HAVE ALREADY SHOWN DEVIATIONS FROM THE EXPECTED MORPHOLOGICAL BEHAVIOR IN THESE SYSTEMS. USING SYNERGISTICGROUND-BASED AND MICROGRAVITY EXPERIMENTS AND THEORETICAL CALCULATIONS THE PROPOSED PROGRAM AIMS TO DEVELOP QUANTITATIVE METRICS FOR THE ASSESSMENT OF BIJELS STABILITY IN THE PRESENCE OF EXTERNAL FORCES SUCH AS GRAVITY AND SURFACE TENSION GRADIENTS DURING BIJEL PROCESSING. SUCCESS OF THE PROPOSED PROGRAM WOULD PAVE THE WAY FOR THE DESIGN AND SYNTHESIS OF NOVEL CO-CONTINUOUS MICROSTRUCTURED COMPOSITES FOR DIVERSE APPLICATIONS IN ADVANCED MANUFACTURING ENERGY NANOTECHNOLOGY AND HEALTH CARE.
