Synthesis Of Stable Colloidal Nanocrystals Using Organic Dendrons, Xiaogang Peng, Haiyan Chen Dec 2006

Synthesis Of Stable Colloidal Nanocrystals Using Organic Dendrons, Xiaogang Peng, Haiyan Chen

Patents Granted

A method for stabilizing colloidal suspensions of nanocrystals or nanoparticles in a solvent or solid matrix is provided by coating the nanocrystals with bulky organic molecules, specifically dendrons, is described. By coating nanocrystals with a dense organic dendron coat and further cross-linking the dendron ligands, oxidation of the nanocrystals and dissociation of the ligands are avoided. This invention allows nanocrystals to undergo rigorous purification and processing. It may regularly be applied to a variety of nanocrystals.


Microfluidics And Small Volume Mixing Based On Redox Magnetohydrodynamics Methods, Ingrid Fritsch, Christopher S. Carter, Zoraida P. Aguilar Dec 2006

Microfluidics And Small Volume Mixing Based On Redox Magnetohydrodynamics Methods, Ingrid Fritsch, Christopher S. Carter, Zoraida P. Aguilar

Patents Granted

Microfluidic channels utilizing magnetohydrodynamics are used to pump very small volumes of solution. The channels have electrodes along the walls of the channel and a current carrying species within the solution carries the current through the solution. The electric field generated by the use of the current carrying species is perpendicular to a magnetic field applied to the channel. The combination of the electric and magnetic fields causes the solution to flow through the channel.


Multilayer Microcavity Devices And Methods, Ingrid Fritsch, Charles S. Henry, Benjamin P. Bowen, Walter R. Vandaveer, Nicole Bratcher Dec 2006

Multilayer Microcavity Devices And Methods, Ingrid Fritsch, Charles S. Henry, Benjamin P. Bowen, Walter R. Vandaveer, Nicole Bratcher

Patents Granted

Microcavities and micropores that are microscopic (mm) in width and depth and contain any number of individually-addressable electrodes separated by insulators along the walls of each cavity are described. The conducting materials, and the insulator materials can be deposited alternately onto a starting substrate, which is typically an oxidized silicon wafer or polyimide film, but may be any substrate that shows good adhesion to the materials layered on it. The cavities are etched through these layers, perpendicular to the plane of the substrate, exposing the layers at their edges. Pores may be carved entirely through the device.

A Comparative Study Of Hybrid And Internet-Based Educational Technology Course Modules, Nilly Adnan Al-Banna Dec 2006

A Comparative Study Of Hybrid And Internet-Based Educational Technology Course Modules, Nilly Adnan Al-Banna

Graduate Theses and Dissertations

The purpose of this study was to examine students’ attitudes and performance toward the teaching methods in an educational technology course. Undergraduate students enrolled in the Educational Technology course ETEC 2002L at the University of Arkansas had been exposed to both on-line modules and in-class instruction. The sample size for this study was 155. The results included 110 valid surveys completed by the students on paper. The data collected from the survey were analyzed using percentages, means, and t test of paired samples to find if there was a significant difference in students’ attitudes toward on-line versus hybrid instruction. Four …


Design Of Novel Experimental Techniques To Investigate The Formation Of Nanoparticle-Based Tribofilms, Corey Thompson Dec 2006

Design Of Novel Experimental Techniques To Investigate The Formation Of Nanoparticle-Based Tribofilms, Corey Thompson

Mechanical Engineering Undergraduate Honors Theses

Nano-engineered lubricant additives such as organically-active nanoparticles of molybdenum disulphide (Hybrid-milled MoS2) are becoming increasingly popular in the fight against harsh friction and wear that occurs during boundary-layer lubrication. A previous paper (Verma, 2007), has reported improvements in both coefficient of friction and wear scar diameter; however, there exists very little data concerning the methods through which this improvement is achieved. Using techniques such as atomic force microscopy (AFM), nanoindentation, scanning electron microscopy (SEM), focused ion beam (FIB), high resolution transmission electron microscopy (HRTEM) as well as tribometery, the chemical and mechanical characteristics of the nanoparticle based tribofilm are characterized. …

Rice Cultivar ‘Banks’, Karen A. K. Moldenhauer, Fleet N. Lee Nov 2006

Rice Cultivar ‘Banks’, Karen A. K. Moldenhauer, Fleet N. Lee

Patents Granted

A rice cultivar designated ‘Banks’ is disclosed. The invention relates to the seeds of rice cultivar ‘Banks’, to the plants of rice ‘Banks’ and to methods for producing a rice plant produced by crossing the cultivar ‘Banks’ with itself or another rice variety. The invention further relates to hybrid rice seeds and plants produced by crossing the cultivar ‘Banks’ with another rice cultivar.


Apparatus And Method For Removal Of Seed Pericarp, Jason M. Cope, Wade Yang, Billy Davidson Nov 2006

Apparatus And Method For Removal Of Seed Pericarp, Jason M. Cope, Wade Yang, Billy Davidson

Patents Granted

Presents an apparatus and method for removing pericarp from a seed, such as a corn kernel. The method includes sonicating the kernel to loosen the pericarp and then separation of the pericarp. One example of separation is by frictional milling. An additional optional aspect of the invention is isolation of the pericarp from the remainder of the seed and/or further cleaning or purification of the pericarp.

The Changing Structure Of Arkansas' Economy: A Shift-Share Analysis, Biswaranjan Das, Daniel V. Rainey Nov 2006

The Changing Structure Of Arkansas' Economy: A Shift-Share Analysis, Biswaranjan Das, Daniel V. Rainey

Research Reports and Research Bulletins

The state of Arkansas enjoys the advantages of its unique central location in the nation, excellent natural surroundings, low cost of living, and one of the best business climates in the southern United States. It is home to several of the largest corporations in the world. Over the period 1980-2000, there was tremendous growth in the state’s economy. However, the growth was confined to specific regions that led to several socio-economic issues adversely affecting the state. To better understand the components and variations in economic growth, a county-wise shift-share analysis was conducted. Employment, a good indicator of economic growth, was …

Understanding Arkansas’ Education Funding Formula, Sarah C. Mckenzie, Gary W. Ritter Oct 2006

Understanding Arkansas’ Education Funding Formula, Sarah C. Mckenzie, Gary W. Ritter

Policy Briefs

Over the last two years, Arkansas’ education funding system has undergone a variety of changes. Despite the news coverage and public attention over education funding, there remains general confusion around the state about school spending. We have produced periodic briefs to help explain the changes; however, we believe that a straightforward question and answer style brief could be helpful in sifting through the various documents about education spending in Arkansas. Four specific questions seem to be discussed consistently regarding education funding: • How much money has been allocated for education in Arkansas? • How has education funding changed over the …

High Quality Colloidal Nanocrystals And Methods Of Preparing The Same In Non-Coordinating Solvents, Xiaogang Peng, Weiyong Yu, David Battaglia Sep 2006

High Quality Colloidal Nanocrystals And Methods Of Preparing The Same In Non-Coordinating Solvents, Xiaogang Peng, Weiyong Yu, David Battaglia

Patents Granted

This invention provides substantially monodisperse colloidal nanocrystals and new preparative methods of synthesis. The methods afford the ability to tune nanocrystal size and size distribution. By using non-coordinating solvents in the synthetic process, these procedures constitute easier, less expensive, safer, and more environmentally “green” methods than those currently in use. The invention is generally applicable to any II-VI or III-V semiconductor material, and may be useful in generating metal-nonmetal compounds involving transition metals as well.
