The research work covers polymer membrane preparation, morphology study, and structural characterization of the membrane and study of the taste sensing characteristics of membrane for five different taste substances. FTIR spectroscopic analysis, UV spectroscopic analysis and SEM were carried for the structure and morphology of polyacrylamide (PAM) grafted cellulose membrane. Sensor characterist...

Jeier Yang is senior at Purdue University majoring in materials science engineering with a minor in biotechnology. She began working under Professor Jeffrey P. Youngblood in the summer of 2015 and continued her research throughout the school year. Her research interests include synthesis of hydrogels and analyzing their mass transport mechanisms involved in drug release. Aside from her research...

We present an internal pumping strategy to enhance solute fluxes in polymer gels. The method is based on electroosmotic flow driven by an electric field applied across a gel that has been doped with charged colloidal inclusions. This work is motivated by the need to enhance the transport in gel-based biosensor devices whose response dynamics are often mass transfer limited. In this case, polyac...

With the continuous exploration and development of unconventional oil gas reservoirs, volume fracturing technology becomes one necessary measures for developing shale tight sandstone reservoirs effectively. Volume usually uses slickwater drag-reducing agent as core system. The composition system is main factor determining its performance. Polyacrylamide has many amide groups in chain, high acti...

Shale gas fracturing flowback fluid is produced during shale exploitation, and its complex composition high chloride content result in limited efficiency of conventional technology. In this work, the Co-TiO2 nanotube array (Co-TiO2 NTAs) electrode with chlorine evolution activity was successfully prepared by electrodeposition for treatment containing PAM simulated wastewater. The internal morph...

The growth dynamics of polyacrylamide hydrogel beads due to liquid absorption under geometric confinement is studied. First, the behavior individual investigated and, subsequently, analyzed in presence several interacting same material. In both, and collective studies, magnitude varied, order investigate effect that stress applied on particles has their hydration kinetics.

Coagulant aids are useful chemicals that enhance the efficiency of coagulation sedimentation treatment. For this purpose, it is necessary to choose safe avoid various risks health those who use treated water. The chitosan, an abundant natural polysaccharide, as a coagulant aid significant not only for water treatment but also effective utilization unused resources, which mostly wasted. We exper...
