Characterizing Strength And Fracture Of Wood Micropillars Under Uniaxial Compression, Xinan Zhang

Masters Theses

The structure of the actual wood cell wall is very complex and it consists of several layers. Some research has been done to measure the mechanical properties of wood cell wall. For example, the hardness and modulus of wood cell wall was estimated using a nanoindentation test. But the mechanical contribution of wood cell wall is not fully understood and documented in the literature. Understanding the micro mechanical properties of the wood cell wall are paramount because of the potential for applications in cellulose nano-composites research and development.

The focus of this research was to investigate the essential of the …

Landowner Decisions And Motivations On The Tennessee Northern Cumberland Plateau: Willingness To Participate In Government Assistance Programs And Reasons For Owning Woodland, Brandon Russell Kaetzel

Masters Theses

The Tennessee northern Cumberland Plateau is a region rich in history and biodiversity that is currently being faced with increased immigration of retirees and new landowners. This influx of people will lead to parcelization of large tracts of forestland, decreases in timber and water quality, and loss of wildlife and biodiversity. For these reasons it is important that the practice of Sustainable Forest Management (SFM) be adopted in the region. SFM is a tool that can be used to increase biodiversity, improve timber quality, and help to sustain the regional economy. This thesis provides results from two different models that …

Effect Of Calendering Of Flexographically Printed Silver Flake Ink, Sujay Pandkar

Masters Theses

Interest in the printed electronics is increasing on a day-to-day basis. To utilize the concept of printed electronics on a wider range, printed circuit needs to perform more and more efficiently. The simplest printed circuit components include conductive traces, which can function as interconnects or contact electrodes. There are still some limitations to the conductivity of printed traces. Previous results showed an improvement in the conductivity of printed traces with a post cure treatment of 4 hours at 105°C. The present research explores a different approach towards improving conductivity using a post calendering treatment on-line.

The effects of calendering temperature, …

The Possibility Of Producing Biodiesel Fuel From Wood Pulping By Products, Yan Pu

Masters Theses

Biodiesel fuel produced from biomass material is a renewable and promising substitute fuel for petroleum diesel fuel, and it is relatively environmentally friendly. The Pulping process involves a huge amount of lignocellulosic materials. There may be a great potential of combining this fact with the biodiesel production, as well as the present biodiesel technologies.

This thesis focuses on the esterification reaction behavior of three main components of tall oil fatty acids, which are byproducts of paper manufacture. They are stearic acid, palmitic acid and oleic acid. Three levels of both catalyst and methanol were employed in the esterification for each …

Effect Of High Temperature Drying Of Paper On Heat Transfer Rates And Sheet Properties, Dania Awni Al-Said

Masters Theses

The objective of this research is to study the effect of high temperature on paper drying rates and properties of both virgin pulp and recycled paper. Process variables as shell temperature, moisture content, refining, basis weight and fiber recycling can affect the drying rate and paper properties. In addition, high surface temperature can affect the heat transfer rates from the dryer shell to the paper. The Gas Heated Paper Dryer (GHPD) is a high temperature dryer where internal shell temperature can reach 300° C, which significantly increases the drying rate. However, there are many concerns about the effect of this …
