The Surface Chemistry And Binding Interactions Of Lignin With Polymer-Encapsulated Gold Nanoparticles Acting As Model Microplastics, Oluwaseun Ayodeji Akinsola Jan 2024

The Surface Chemistry And Binding Interactions Of Lignin With Polymer-Encapsulated Gold Nanoparticles Acting As Model Microplastics, Oluwaseun Ayodeji Akinsola

All Master's Theses

This study investigates the surface chemistry and molecular-level interactions between lignin, a special type of natural organic matter, and polymer-capped gold nanoparticles, shedding light on the strength of adsorption between lignin and nanoscale polymer surfaces. Specifically, the study presents a variety of nanoscale polymer surfaces displaying different charged functional groups, using layer-by-layer assembly of three polyelectrolytes (polyallylamine hydrochloride (PAH)), polyacrylic acid (PAA), and poly(diallyldimethylammonium chloride (PDADMAC)) on 90 nm citrate-stabilized gold nanoparticles (AuNPs). This approach provides a library of polymer-encapsulated AuNPs for investigating the binding interactions of lignin to nanoscale polymers via spectroscopic techniques. ζ-potential, dynamic light scattering (DLS), …


No Ape Left Behind: Orangutan Conservation Education Project, Danna Boshak Jan 2021

No Ape Left Behind: Orangutan Conservation Education Project, Danna Boshak

All Graduate Projects

Orangutans are critically endangered and if action is not taken, their extinction is imminent. Zoological institutions worldwide serve as an educational means to engage the broader public in conservation awareness and action behaviors. The Association of Zoos and Aquariums (AZA) created the Saving Animals From Extinction (SAFE) initiative to provide zoos with a platform to expand conservation efforts beyond their institutions. In collaboration with the Orangutan SAFE (OSAFE) education committee, the No Ape Left Behind: Orangutan Conservation Education Project develops educational activity resources that provide information about orangutan behavior and ecology as well as action items that individuals can take …


Dual-Axis Solar Tracker, Bryan Kennedy Jan 2020

Dual-Axis Solar Tracker, Bryan Kennedy

All Undergraduate Projects

Renewable energies, and fuels that are not fossil fuel-based, are one of the prolific topics of debate in modern society. With climate change now becoming a primary focus for scientists and innovators of today, one of the areas for the largest amount of potential and growth is that of the capturing and utilization of Solar Energy. This method involves using a mechanical system to track the progression of the sun as it traverses the sky throughout the day. A dual-axis solar tracker such as the one designed and built for this project, can follow the sun both azimuthally and in …


Post-Glacial Fire History Of Horsetail Fen And Human-Environment Interactions In The Teanaway Area Of The Eastern Cascades, Washington, Serafina Ferri Jan 2019

Post-Glacial Fire History Of Horsetail Fen And Human-Environment Interactions In The Teanaway Area Of The Eastern Cascades, Washington, Serafina Ferri

All Master's Theses

Landscapes of the Pacific Northwest have been shaped by dramatic shifts in climate since the last glacial maximum and more recently, by human activity. However, it is unclear how past relationships between people, fire, and climate interacted on the landscape. The purpose of this research was to reconstruct the post-glacial fire history of a wetland known as Horsetail Fen, located in the Teanaway area of the eastern Cascades of Washington State. The goal was to evaluate how fire activity has varied under different climatic scenarios during the last ~16,000 years and in relation to human land-use actions. This lake was …


Water Quality Assessment: A Hands-On Approach To Environmental Education, Tracy Lynn Royse Jan 2004

Water Quality Assessment: A Hands-On Approach To Environmental Education, Tracy Lynn Royse

All Graduate Projects

A water quality assessment lab manual has been created to assist secondary educators using the HACH water quality testing kits. It consists of ten chemical tests, a geological survey and a biological assessment largely based upon Washington State University's lab format and the Walla Walla County Conservation District's water study protocol. The lab manual also contains safety guidelines, a scoring rubric and an action plan research project. The environmental approach to science education used in the lab manual meets the Essential Academic Learning Requirements adopted by the Washington State Commission on Student Learning as well as the National Science Education …


An Integrated Fire Ecology Curriculum For The Eastern Slopes Of The Cascade Mountain Range For Grades 4-7, Amy E. Starkovich Jan 2000

An Integrated Fire Ecology Curriculum For The Eastern Slopes Of The Cascade Mountain Range For Grades 4-7, Amy E. Starkovich

All Graduate Projects

The purpose of this project was to create a curriculwn to increase the opportunity for young people in Central Washington to receive fire ecology education which will allow them to gain fundamental knowledge of how the Central Washington forest ecosystems work as well as develop a sense of stewardship toward our local forests. An integrated fire ecology curriculum aligned with the Washington State Essential Academic Learning Requirements was created. The curriculum includes teacher and student information, lessons, activities, resources, and recommendations to increase student understanding of the wildfires which impact many communities in Central Washington every summer.


A Guide For Extending Nature Lessons At The Yakima Arboretum, Marilou Cori Kinder Jan 1996

A Guide For Extending Nature Lessons At The Yakima Arboretum, Marilou Cori Kinder

All Graduate Projects

The importance of providing a hands on natural environment curriculum was examined. Sources from 1938-1996 were found supporting the importance of such a curriculum. A search was conducted on the availability of a natural habitat curriculum that used a local resource. The search discovered the Yakima Arboretum had seven areas of interest along with a packet of brief lesson suggestions. These lessons were extended to include classroom activities that would provide students with background knowledge prior to a field trip to the Arboretum.


A Recycling Proposal For The Vashon Island School District, John Turner Green Jan 1990

A Recycling Proposal For The Vashon Island School District, John Turner Green

All Graduate Projects

The purpose of this study was to identify a process by which the Vashon Island School District could reduce its waste stream and involve and educate students in an environmental ethic that actively seeks to reduce and recycle wastes. A search of the general and educational literature was made. An extensive research of state and local agencies helped to identify appropriate goals and actions for the Vashon School District. The proposal calls for seven specific actions to be taken.
