Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

Creator:: Li, Cheng
Abstract:: Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

Density Functional Theory Study of the Reaction Mechanism of Chloride-induced Depassivation of α-Fe2O3

Creator:: Pang, Qin
Abstract:: Carbon steel, which contains mostly iron, has been widely used as reinforcement in reinforced concrete. In the alkaline environment in reinforced concrete, a thin iron oxide film, called the passive film, forms on the surface of the steel, which protects the surface from active corrosion. The exact atomic structure of...

Synthesis of Intercalation Compounds and Nanocomposites of Inorganic Layered Hosts

Creator:: Liyanage, Medagama Liyanage Amila Udayanga
Abstract:: Novel synthetic strategies are developed to prepare new intercalation compounds and nanocomposites with several layered hosts (NiPS₃, Na-montmorillonite, MoS₂ and MoO₃). In these products, alkali metals are ionic intercalates and linear polymers, dendrimers or amines act as co-intercalates. In addition to new synthetic approaches, new structures are identified and characterized....

Organic-solvent resistant ultrafiltration and nanofiltration membrane modules for separation and purification of nanoparticles

Creator:: Kim, Taehyeong
Abstract:: The intriguing size- and shape dependent properties of nanoparticles have garnered recent attention in many science and engineering areas. When the particle size is in the nanometer size range, the material exhibits very different properties such as surface plasmon resonance (of gold nanoparticles) and superparamagnetism (of iron oxide nanoparticles). The...

Femtosecond Stimulated Raman Studies of Excited State Structural Events

Creator:: Tang, Longteng
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...
