Please consider attending this seminar: MATERIALS ENGINEERING SEMINAR "The Use of Temporally Programmed Biaxial Deformation Profiles to Affect Morphological and Dielectric Properties of Polyethylene Terephthalate Films" By Jiahao Mao Purdue MSE Preliminary Exam Advisor: Professor Mukerrem Cakmak ABSTRACT Discovering novel dielectric materials has been a long-time ambition in material science and is becoming increasingly important, especially for advanced military and energy storage applications. With the development of the technology, scientists are focusing on materials with not only high breakdown strength and high dielectric constant, but other extraordinary properties such as scalability, light weight, and tunability. Polymer materials, especially polymer thin films, have higher breakdown strength and better stability as compared with their traditional ceramic counterparts. More than that, with their advantageous behavior in being stretchable and shapable in intricate geometries, polymer dielectric materials have become popular in the recent years. Numerous studies have been carried out to reveal the relationship between the morphological structures and the dielectric properties of semicrystalline polymers. Polyethylene terephthalate (PET), with its excellent dielectric properties, ideal transparency when crystallized, and processing-enhanced behavior, has been studied for decades. However, there is not much work published about how the dielectric properties change with the varying of morphological structures of the PET. In this study, we use temporally varying deformation profiles to optimally affect morphological evolution (crystallinity, orientation, crystal size) and resulting dielectric properties of Polyethylene terephthalate films from amorphous precursors for capacitor applications. This will be accomplished with custom build programmable biaxial stretcher that can apply desired programmed deformation profiles to films from amorphous unoriented precursors while measuring true stress, true strain and optical birefringeces real time to investigate stress optical and strain optical behavior to very large deformation levels typically used in industrial manufacturing processes. The structure and dielectric properties (dielectric constant, loss, breakdown) as well as structural parameters of films including crystallinity, orientation, crystal size will be characterized off line to assess deeper understanding of their relationships.

Please consider attending this seminar: MATERIALS ENGINEERING SEMINAR "Cold Atmospheric Plasma (CAP)-Assisted Surface Modification and Functional Materials Deposition for Flexible Electronic Devices" By Venkat Kasi Purdue MSE Preliminary Exam Advisor: Professor Rahim Rahimi ABSTRACT Functional thin films consisting of inorganic, organic, or hybrid materials are considered the backbone of electronic devices for many different applications ranging from flexible displays to sensors. The use of additive manufacturing for the fabrication of flexible electronics has significantly increased over the last few decades. Compared to the traditional subtractive etching and photolithography processes, the manufacturing process of flexible electronics through additive manufacturing offers many benefits including faster time to market through rapid prototyping, aptness to on-demand and small batch fabrication, roll-to-roll manufacturing, significant reduction in waste generation, and elimination of complex vacuum systems. However, the use of traditional additive manufacturing techniques such as screen printing, inkjet printing, and gravure printing is also limited by the requirement of solvent processable inks for the deposition of functional coatings. Cold atmospheric plasma chemical vapor deposition (CAP-CVD) has become an attractive additive manufacturing technology to synthesize and deposit different organic and inorganic materials directly onto the desired substrate under atmospheric conditions. In this work, we investigate for the first time the possibility of using CAP-CVD as an alternative approach to deposit functional materials for flexible electronic applications under atmospheric conditions. Also, as part of this investigation, we have addressed one of the key challenges in the field of electrochemical sensors, which is the water layer formation at the interface due to weak bonding between ion-selective membrane and the electrode causing potential drift and inconsistency in potential responses.

Please consider attending this seminar: MATERIALS ENGINEERING SEMINAR "MOLECULAR AND ATOMIC FEATURIZATION METHODS FOR PREDICTIVE MODEL DESIGN" By Robert Appleton Purdue MSE Preliminary Exam Advisor: Professor Alejandro Strachan ABSTRACT Materials and molecular sciences have been concerned with the way chemical and structural information is represented when passed to a model for a number of decades. This has resulted in a large variety of options when it comes to representing atomic systems. Therefore, it can be challenging to optimize the representation and resulting descriptors for a specific application. Methods for dimensionality reduction and feature selection have been developed to aid researchers in this area. This review discusses the history of the representations that have been proposed and how they have been applied, as well as a demonstration of how dimensionality reduction and feature selection can be utilized to optimize the inputs for a given model.
