Thermal Conductivity And Mechanical Properties Of Interlayer-Bonded Graphene Bilayers, Afnan Mostafa
Thermal Conductivity And Mechanical Properties Of Interlayer-Bonded Graphene Bilayers, Afnan Mostafa
Masters Theses
Graphene, an allotrope of carbon, has demonstrated exceptional mechanical, thermal, electronic, and optical properties. Complementary to such innate properties, structural modification through chemical functionalization or defect engineering can significantly enhance the properties and functionality of graphene and its derivatives. Hence, understanding structure-property relationships in graphene-based metamaterials has garnered much attention in recent years. In this thesis, we present molecular dynamics studies aimed at elucidating structure-property relationships that govern the thermomechanical response of interlayer-bonded graphene bilayers.
First, we present a systematic and thorough analysis of thermal transport in interlayer-bonded twisted bilayer graphene (IB-TBG). We find that the introduction of interlayer C-C …
Micro And Nano R2r Embossing Of Extruded Polymers, Raymond S. Frenkel
Micro And Nano R2r Embossing Of Extruded Polymers, Raymond S. Frenkel
Doctoral Dissertations
This dissertation presents a process for directly imprinting or embossing extruded polymers as an advancement in roll-to-roll (R2R) embossing methods that avoids the problems of converting preformed films, increases throughput, and reduces costs. A proof-of-concept R2R apparatus was designed and constructed for directly embossing extruded polymer, and experimental results were evaluated. This laboratory scale R2R apparatus employed a thin metal ribbon belt mold with micro or nano scale features in a calendering setup, with a close coupled induction heating (IH) coil to preheat the ribbon mold above glass transition temperature (Tg) of the polymer, prior to contact with …

Reprogramming And Imaging Of Tumor Associated Macrophages Using Spuramolecular Nanoparticles, Anujan Ramesh
Doctoral Dissertations
Macrophages are highly plastic cells that are a part of the mononuclear phagocytic system and play a crucial role in both the innate and the adaptive immune systems. Although they have functionally diverse roles involved in physiological and pathological processes, they primarily act as phagocytes that aid in clearing infections. During these instances of tissue injury or infections, circulating monocytes are recruited to the site of the injury, where they differentiate to give rise to macrophages that have a pro-inflammatory function. These monocytes derived macrophages, however, exist across a spectrum of phenotypes based on the local tissue environment. The two …
