Cellulose Based Separator For High-Performance Lithium-Ion Batteries, Akshit Vaidya 2020 Western Michigan University

Cellulose Based Separator For High-Performance Lithium-Ion Batteries, Akshit Vaidya

Master's Theses

During the past two decades, lithium-ion batteries (LIBs) have gained great success in the field of portable devices, and currently, are penetrating to the market of vehicles. Compared to the fast development of LIBs, little efforts have been dedicated to the separator, which is one of the most important components of LIBs. Primarily, the lithium-ion battery separator has two functions, one is to prevent direct contact between the positive and negative electrodes, and the other is to provide a path for effective ionic transportation. Currently, the separator market of LIBs is dominated by polyolefin materials such as polypropylene, polyethylene, and ...

Paper Structure Formation Simulation, Tyler R. Seekins 2019 University of Maine

Paper Structure Formation Simulation, Tyler R. Seekins

Electronic Theses and Dissertations

On the surface, paper appears simple, but closer inspection yields a rich collection of chaotic dynamics and random variables. Predictive simulation of paper product properties is desirable for screening candidate experiments and optimizing recipes but existing models are inadequate for practical use. We present a novel structure simulation and generation system designed to narrow the gap between mathematical model and practical prediction. Realistic inputs to the system are preserved as randomly distributed variables. Rapid fiber placement (~1 second/fiber) is achieved with probabilistic approximation of chaotic fluid dynamics and minimization of potential energy to determine flexible fiber conformations. Resulting digital ...

Soy- Based Flexographic Ink For Linerboard Printing, Pingale 2018 Western Michigan University

Soy- Based Flexographic Ink For Linerboard Printing, Pingale

Master's Theses

Many printing inks use volatile solvents in the formulation, which are hazardous to the environment from emission of VOC’s and at the same time, synthetic resins in these inks are not biodegradable. These problems with the fluctuating and rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. The majority of the commercially available water based inks are formulated based on using acrylic resins, synthetic colorants, solvents/water and additives, which are the common main components for formulating printing inks. In this research, soy proteins were tested for their suitability ...

Impact Of Substrate And Process On The Electrical Performance Of Screen-Printed Nickel Electrodes: Fundamental Mechanism Of Ink Film Roughness, Bilge N. Altay, Jerome Jourdan, Vikram S. Turkani, Hervé Dietsch, Dinesh Maddipatla, Alexandra Pekarovicova, Paul D. Fleming, Massood Atashbar

Bilge Nazli Altay

In recent years, traditional printing methods have been integrated to print flexible electronic devices and circuits. Since process requirements for electronics diff er from those for graphic printing, the fundamentals require rediscovery mainly to optimize manufacturing techniques and to find cost reduction methods without compromising functional performance. In addition, alternative inks need to be formulated to increase the variety of functional inks and to pioneer new product developments. In this report, we investigate a thermoplastic-based nickel ink prototype to print electrodes using a screen-printing process. Process fundamentals are explored, and cost reduction methods are addressed by studying ...

Bio-Based Polyurethane Foams Made From Microwave Liquefaction Of Biomass, XINGYAN HUANG 2018 Louisiana State University and Agricultural and Mechanical College

Bio-Based Polyurethane Foams Made From Microwave Liquefaction Of Biomass, Xingyan Huang

LSU Doctoral Dissertations

Polyurethane (PU) foam is one of the most versatile construction insulations due to its low density, low thermal conductivity, and high mechanical performance. However, it is still highly dependent on petro-based chemicals, i.e. polyol and isocyanate. In this work, biomass, such as rape straw, switchgrass, and yaupon holly (Ilex vomitoria) were liquefied using microwave energy to produce bio-based polyol in order to substitute petro-based polyol in the production of PU foam. Cellulose nanocrystals (CNCs) were also extracted from liquefaction solid residue. They were then applied to reinforce high bio-content PU foam. Moreover, lignin was fractionated from bio-polyol by adding ...

Printed Dot Quality In Response To Doctor Blade Angle In Gravure Printing, Bilge N. Altay, Alexandra Pekarovicova, Paul D. Fleming

The Hilltop Review

Doctor blade is one of the critical machine part of the gravure printing press that controls the amount of ink transfer on the substrate. The angle of the blade can be varied; however, an improper angle may cause major problems. In this study, the doctor blade angle was positioned at three different level to address its effect on the printed dot quality. Print trials were made on a web-fed gravure press at the speed of 650 ft./min. A high-resolution overhead camera was used to analyze the key dot attributes. The results showed that measuring only the density of printed ...

Papermaking Factors Affecting Lateral Web Position During Commercial Heat Set Web Offset Printing, Shields 2017 Western Michigan University

Papermaking Factors Affecting Lateral Web Position During Commercial Heat Set Web Offset Printing, Shields

Master's Theses

The interaction of water with paper plays a role in web handling characteristics during commercial heat set web offset printing. Water absorption leads to lower web tension for a given strain.

This research investigates paper properties and their role in preventing lateral web movement from cross machine air flows in the drying section during normal printing operations. Tensile properties of sheets are measured at various moisture contents and then used to determine the equilibrium stress-strain relationship for papers at moisture contents typical of heat set web offset printing. Permeability, fiber orientation and tensile stiffness are evaluated against lateral web movement ...
