Tailoring Particle Behavior for Phase Transfer Catalysis: Recent Developments by the Center for Interfacial Reaction Engineering

Aichele C.P., Weston J., Venkataramani D., Briggs N., Crossley S., Harwell J., White J., Resasco D., Oklahoma State University, US

This presentation highlights recent advances by the Center for Interfacial Reaction Engineering (CIRE) in designing and tailoring catalytic particles for use in phase-transfer catalysis. CIRE consists of researchers across several disciplines including nanotechnology, thermodynamics, interfacial [...]

Manufacturing Tough Amorphous Thermoplastic-Graphene Nanocomposites

Bandla S., Hanan J.C., Oklahoma State University, US

Nanocomposites have been studied for more than two decades because of their superior performance in comparison with traditional composites. However, few products made using nanocomposites are available commercially. Achieving uniform dispersion in the polymer matrix, [...]

Single molecule SERS leads to the observation of the intermediate form of green fluorescent protein chromophore

Shafiq N.Z., Shafayet Khurshid Md., Kaan Kalkan A., Oklahoma State University, US

The dominant absorption band at 395 nm of the green fluorescent protein (GFP) is attributed to the protonated form of the chromophore. Photo excitation forms an excited intermediate anion from this excited protonated form and [...]

Monitoring of glass transition at a polymer surface by localized surface plasmon resonance

Kaan Kalkan A., Putla R.K., Oklahoma State University, US

The temperature below which a polymer is in glassy state and above which is in viscous state is called the glass transition temperature (Tg). Investigations on polymer surfaces by various groups revealed that the surface [...]

Single Transistor AND Gate

Chengalvala V., Zhang Y., Oklahoma State University, US

Double-gate SOI MOSFET structure opens the door for many novel devices by the coupling of the two gates. If the same voltage is applied to both gates, the depletion regions are equally partitioned. On the [...]

Simulation of Heterojunction Bipolar Transistor with Domain Decomposition Method

Zhang Y., Ruden P.P., Oklahoma State University, US

Domain decomposition method is used in simulation of the band profile and the majority carrier concentration profile of AlGaN/GaN heterojunction bipolar transistors. The method is very stable and efficient. With this method different device structures [...]
