Synthesis And Characterization Of Functionalized Nanomaterials: Heterogeneous Palladium Catalyst And Lithium-Doped Graphene Oxide, Benjamin E Estes
Synthesis And Characterization Of Functionalized Nanomaterials: Heterogeneous Palladium Catalyst And Lithium-Doped Graphene Oxide, Benjamin E Estes
Doctoral Dissertations
As the Earth's population increases and natural resources decrease in supply, the development of new methods for energy storage and the efficient production of industrial chemicals becomes ever more important to humanity. The development of new nanomaterials may offer technological advances in the fields of sustainable energy production and storage, chemical production, medicine, and many others. The emerging field of nanoscience blends chemistry, physics, and engineering to create new materials that take advantage of properties found only on the nanoscale.
In this work, mesoporous silica spheres are used as a support for nanoparticles of palladium. This nanomaterial is shown to …
Theoretical Modeling Of The Formation And Functionality Of Low-Dimensional Materials, Hua Chen
Theoretical Modeling Of The Formation And Functionality Of Low-Dimensional Materials, Hua Chen
Doctoral Dissertations
This dissertation presents a series of work under the topic of designing and modeling novel low-dimensional materials and structures with desired and coherent structural, electronic, and magnetic properties, using a variety of theoretical tools, including first-principles density functional theory (DFT) method, numerical Monte Carlo (MC) method, and analytical phenomenological approaches, etc. The contents are divided into three major topics:
(1) Magnetic properties of n-p codoped materials. The noncompensated n-p codoping method is proposed to increase the density of magnetic dopants in diluted magnetic semiconductors (DMS) while keeping the magnetic coupling strength, which may lead to a …
