Electrical characteristics of individual FeNiCo-Au core-shell nanowires integrated into microelectrodes on plastic substrate

Beheshti M., Geng X., Choi J., Podlaha-Murphy E., Park S., Louisiana State University, US

Synthesis, characterization and integration of single metallic nanowires with enhanced electrical and mechanical properties into plastic substrate is a vital task for the development of transparent/flexible electronics as well as nanosensors. Among the metallic nanowires, [...]

Gas-Assisted Gravity Drainage – A New Process for CO2 Sequestration and Enhanced Oil Recovery

Rao D.N., Louisiana State University, US

The current commercial practice of gas-based enhanced oil recovery processes involves either continuous gas injection (CGI) or Water-Alternating-Gas (WAG) injection. Over 60 commercial projects in West Texas and other parts of the world have amply [...]

Soft X-Ray Lithography for High-Aspect Ratio Sub-Micrometer Structures

Goettert J., Lemke S., Rudolph I., Seliger T., Loechel B., Louisiana State University, US

Combining soft x-ray lithography with SiN mask membrane and newly developed high contrast negative resist mr-X (micro resist technology GmbH, Berlin, Germany) enables the cost-effective patterning of sub-micrometer high aspect ratio structures. This work builds [...]

Fabrication and Characterization of HAR Microfluidic Device to Concentrate Microalgae

Singh V., Nguyen Q., Goettert J., Yemane D., Bargiel J., Lane C., Stephenson F., Louisiana State University, US

Algae are a promising candidate for large-scale production of biofuels, an important source of renewable energy [1]. A significant portion (20-40%) of the cost in the traditional processing comes from concentrating (dewatering) the algae from [...]

Nanofluidic Channel Based Single Molecular Sensors in Polymer Substrate Fabricated by Novel Nanoimprinting Processes

Wu J., Chantiwas R., Soper S.C., Park S., Louisiana State University, US

One critical challenge in developing innovative nanochannel-based sensors for bio/chemical analyses is to build multiscale structures composed of narrow, long and continuous fluidic nanochannels and microfluidic networks at low cost. We presents a novel process [...]

Influence of resist composition on demolding force in UV nanoimprint lithography

Amirsadeghi A., Lee J., Park S., Louisiana State University, US

We investigated the influence of the Young’s Modulus (E) of UV resist on the measured demolding force in UV-NIL by varying compositions of UV-curable polymers. We found that decreasing crosslinking content of the polymers decreases [...]

Simple Fabrication of Hierarchical Structures on a Polymer Surface

Farshchian B., Hurst S.M., Ok J.T., Park S., Louisiana State University, US

In this study, inspired by multiscale structures found in nature like lotus leaf we will try to make multiscale structures on polymer surfaces to make their surface superhydrophobe. We introduce a novel and effective method [...]

Microfluidic Platforms with Micro- and Nanopore Membranes and in situ Formation of Lipid Bilayer in the Microfluidic Platform

Choi J., Kim N., Park S., Louisiana State University, US

Artificial lipid bilayer membranes have come into the spotlight as topics of fundamental properties of biomaterials, targets for drug discovery and safety screening, and analytic platforms for characterization and orientation discrimination of polynucleotide molecules. Lipid [...]

Fabrication of Nanostructures on Curved Surfaces Using PDMS Stamp

Farshchian B., Park S., Louisiana State University, US

In this study we report on a simple and effective process that allows direct imprinting of micro- and nanostructures on concave and convex substrates using a flexible stamp and pressurized air . One of the [...]

Characterization of Different Surfaces Morphology in Heterogeneous Catalyst

Mukherjee R., Palazoglu A., Romagnolia J.A., Louisiana State University, US

Structures and property of surface are very important in different chemical, physical and biological process. The interaction between the reactant molecules (adsorbate) and the surface are important in the performance of the catalyst. Surface with [...]
