Novel Interfacial Syntheses of Covalent Organic Frameworks

Creator:: Liu, Ziyan
Abstract:: Covalent organic frameworks (COFs) are an emerging type of microporous crystalline polymers connected by organic units via strong covalent bonds. Due to the well-defined crystalline structure and excellent chemical and thermal stabilities, COF materials are being considered as promising candidates in a variety of applications, such as gas adsorption, catalysis...

Removal of cryoprotectant with the use of a microseparation device

Creator:: Lusianti, Ratih E.
Abstract:: Cryoprotectants (CPAs) such as glycerol and dimethyl sulfoxide (DMSO) are commonly used during cryopreservation of cell based therapeutics. Although these additives are beneficial during freezing, it is often desirable to remove them before infusion into a patient. Currently, the most common method for CPA removal is by centrifugation. This method...

Growth, Characterization and Applications of Zinc Sulfide Thin Films by Solution-Based Processes

Creator:: Chiu, Dick
Abstract:: Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices. In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...

Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

Creator:: Wang, Maoyu
Abstract:: Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

Human platelet adhesion to heparinized silica surfaces

Creator:: Bolsinger, Travis Samuel Sebastian
Abstract:: Heparin was modified and immobilized to surface-activated silica surfaces using two different reaction schemes. End-aminated heparin was reacted with 2-iminothiolane to produce free thiol groups at the terminal ends of the heparin chains. The end-thiolated heparin was immobilized by reaction with a pyridyl disulfide activated poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock...

Molecular origins of surfactant-mediated stabilization of protein

Creator:: Lee, Hyo Jin
Abstract:: Nonionic surfactants are commonly used to stabilize proteins during upstream and downstream processing and drug formulation. Surfactants stabilize the proteins through two major mechanisms: (i) their preferential location at nearby interfaces, in this way precluding protein adsorption; and/or (ii) their association with protein into "complexes" that prevent proteins from interacting...

Heteroaggregation of gold nanoparticles with model colloids and the influence of environmental aqueous chemistry

Creator:: Pike, Daniel J.
Abstract:: Nanoparticles are becoming increasingly important in numerous technological fields but evidence shows that they can be toxic to many organisms. To predict their fate and transport in the environment, nanoparticle attachment to naturally occurring colloids must be examined. This study investigated citrate-capped gold nanoparticle (Cit-AuNP) heteroaggregation with two model colloids...

Oxide dispersion strengthened 304L stainless steel produced by ink jetting and laser powder bed fusion

Creator:: Paul, Brian K., Lee, Kijoon, He, Yujuan, Ghayoor, Milad, Chang, Chih-hung, and Pasebani, Somayeh
Abstract:: This paper discusses the fundamentals of a novel hybrid method to synthesize oxide dispersion strengthened (ODS) 304 L stainless steel (SS) alloy using a modified laser powder bed fusion (LPBF) machine. Previously, ODS metal matrix composites have been produced by LPBF via ball-milling, which is expensive to scale. Here, we selectively...

2,4,6-trinitrotoluene detection using photoluminescence response of diatom biosilica functionalized with single-chain variable fragment

Creator:: Zhen, Le
Abstract:: A label-free, photoluminescence (PL) based biosensor for 2,4,6-trinitrotoluene (TNT) detection was developed by functionalizing diatom biosiilica with a TNT-specific single-chain variable fragment (scFv). The scFv loading was estimated to be 0.040±0.003 (μg scFv/μg biosilica). In saturated concentration, TNT binding to scFvbiosilica quenched about 13% of its PL. Dose response follows...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...
