Studies on effect of stabilizers, chelators and inherent periodicity on nanoparticle antioxidant activity

Creator:: Zhou, Zheng
Abstract:: The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...

Low-temperature, Inkjet-printed p-Type Copper(I) Iodide-based Thin-Film Transistors

Creator:: Gorecki, Jenna Y.
Abstract:: Inkjet-printed p-type copper(I) iodide-based TFTs were successfully fabricated. As-printed copper(I) halide semiconductor films, such as CuI, CuBrI, and CuClI, were used as p-type active channel layers for TFTs. The entire process of the TFTs fabrication was maintained under 150 °C, which is compatible with flexible plastic substrates and transparent glass...

Experimental Study of Nucleate Boiling Bubble Dynamics and Heat Transfer Enhancement on Printed Bi-functional Surfaces

Creator:: David, Michele
Abstract:: Boiling heat transfer is studied for its ability to dissipate high fluxes and achieve heat transfer coefficients two orders of magnitude greater than single-phase heat transfer systems. Heater surface enhancement with increased surface area, varied geometry, wettability contrast and micro/nano-structures can further enhance boiling heat transfer performance through bubble nucleation...

CdS nanocrystalline thin films deposited by the continuous microreactor-assisted solution deposition (MASD) process : growth mechanisms and film characterizations

Creator:: Su, Yu-Wei
Abstract:: The continuous microreactor-assisted solution deposition (MASD) process was used for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) glass. The MASD system, including a T-junction micromixer and a microchannel heat exchanger is capable of isolating the homogeneous particle precipitation from the heterogeneous surface reaction. The results show...

Model programming of a direct contact condenser in solvent free microwave extraction of peppermint oil

Creator:: Du, Yihao
Abstract:: Solvent free microwave extraction (SFME) has been demonstrated to be feasible in extraction of essential oils from botanical materials. The benefits are no need for any solvent aside from the water naturally in the botanical material and a significant reduction in environmental impact for large scale production processes. However, the...
