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...

Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

Creator:

Alemu, Yagenetfere A.

Abstract:

The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

Fabrication of Biological Pigment Nanowires by Inkjet Printing

Creator:

Cao, Yu

Abstract:

Digital inkjet printing is developing quickly today because inkjet printing processes consume less energy and water and produce less waste discharge than traditional dyeing and other printing technologies. Inkjet printing provides more versatility and flexibility in terms of printing patterns and colors. Natural pigments are gaining more attention today as...

Efficiency of a direct contact condenser in the presence of the noncondensable gas air compared to a tube and shell condenser

Creator:

Lebsack, Jonathan M.

Abstract:

Steam distillation is the traditional method used for the extraction of peppermint oil. This process is able to remove approximately 20% of the oils from the leaves of the plant. It is a very costly and un-sustainable process due to the release of carbon emissions. Solvent free microwave extraction promises...

Investigating the Effect of Tetrahydrofuran (THF) Plasticizer on the Crystallization and Solvent Seaming of PET/NPG Copolymer Films

Creator:

Srivastava, Aarushi

Abstract:

Polyethylene terephthalate (PET) polymer has been the material of choice for packaging industry as a result of its excellent mechanical and physical properties. These properties are highly dependent on the microstructure, chemistry, and processing conditions of this material. PET is often oriented in the machine direction (MD), the transverse direction...

Using a membrane reactor for the sulfur-sulfur thermochemical water-splitting cycle

Creator:

Knapp, Nathan Michael

Abstract:

The hydrogen economy is a possible component of an energy future based on use of alternative and renewable energy sources, deemed desirable from the general consensus of the worldwide community that we do not want to further exacerbate the climate problems that we have introduced over the last two centuries...

Upgrading of a model compound of bio-oil using carbon monoxide in high temperature water

Creator:

Phipps, Ezra Daniel

Abstract:

Meeting the energy demands of the future is one of the most important challenges facing the engineering community today. An example of this problem is transportation fuels. Most of the current transportation fuels are composed of petroleum hydrocarbons. Finding a viable alternative is important given the potential scarcity of these...

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...

Spray drying for erythrocyte preservation at room temperature

Creator:

Leu, Hsuan-Yu

Abstract:

Spray drying has been widely used in food science for long-term storage of products such as powdered milk, and it has recently been used for preservation of more temperature sensitive products such as human blood plasma and single-cell organisms. However, there are no previous reports of successful spray drying of...

Continuous and rapid synthesis of nanoclusters and nanocrystals using scalable microstructured reactors

Creator:

Jin, Hyung Dae

Abstract:

Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...
