The role of triplet excitons in enhancing polymer solar cell efficiency: a photo-induced absorption study
(arXiv, 2009)
Inclusion of heavy metal atoms in a polymer backbone allows transitions between the singlet and triplet manifolds. Interfacial dissociation of triplet excitons constitutes a viable mechanism for enhancing photovoltaic (PV) ...
Polyfluorene as a model system for space-charge-limited conduction
(arXiv, 2008)
Ethyl-hexyl substituted polyfluorene (PF) with its high level of molecular disorder can be described very well by one-carrier space-charge-limited conduction for a discrete set of trap levels with energy $\sim$ 0.5 eV above ...
The role of triplet states in the emission mechanism of polymer light-emitting diodes
(arXiv, 2009)
The blue emission of polyfluorene (PF) based light-emitting diodes (LEDs) is known to degrade due to a low energy green emission, which hitherto has been attributed to oxidative defects. By studying the electroluminescence ...
Commercialization of novel biomarkers of male fertility in humans and farm animals
(2010-03)
Each year, US infertility clinics treat 135,000 couples who fail to conceive naturally. Up to 40% of these infertility cases can be attributed to male infertility stemming from poor sperm quality. An additional 20% of ...
Organ printing: a novel tissue engineering paradigm
(2010)
Engineering new tissues, ideally from the patient's own body cells to prevent rejection by the immune system, is a rapidly growing field that rests on three pillars: cells, supporting structures (or scaffold) and stimulating ...
Research in motion
(2010-03)
Orthopaedic disorders of the major joints, specifically, osteoarthritis of the hip and knee joints have an enormous economic and functional impact on our society, affecting millions of patients every day. In the late 1960s ...
Building Innovative Corporate-Academic Partnerships: What is Needed?
(University of Missouri (System), 2010-03)
The panelists presented corporate perspectives on the building blocks necessary to sustain innovative, profitable partnerships.
The Role of Life Sciences in Building Regional Economy
(University of Missouri (System), 2010-03)
The panel of Missouri and Kansas legislators discussed the role of the life sciences in building the regional economy.
Animal to human health collaborations : the path forward
(University of Missouri (System), 2010)
University and business community leaders discussed lessons learned from the summit and charting a road map forward.
College freshmen's perception of racism at the University of Missouri-Columbia : do you see what I see?
(University of Missouri--Columbia, 2007)
This dissertation examines the perceptions that college freshmen have of racism on the University of Missouri-Columbia campus (UMC). A detailed history of the social interactions that have occurred between Blacks and Whites ...
Teachers' knowledge of algebraic reasoning : its organization for instruction
(University of Missouri--Columbia, 2007)
Teacher knowledge is a critical factor that influences instructional decisions. Elbaz (1983) stated, "the single factor which seems to have the greatest power to carry forward our understanding of the teachers' role is the ...
Development of tailored preform processing technology for net-shape manufacturing of large monolithic structures
(University of Missouri--Columbia, 2007)
The aim of the present research effort involves exploration of a new processing approach, "Tailored Preform Processing (TPP)" technology for net-shape manufacturing of monolithic structures for the transportation industry. ...
Structural studies of acid phosphatases from pathogenic bacteria
(University of Missouri--Columbia, 2007)
Acid phosphatases are important, ubiquitous, and diverse group of enzymes that catalyze the transfer of phosphoryl from phosphomonoester to water forming inorganic phosphate and alcohol. These enzymes play critical roles ...
The role of mentoring in developing beginning principals' instructional leadership skills
(University of Missouri--Columbia, 2007)
The purpose of this study was to investigate the type of support provided by mentors in helping new principals develop instructional leadership skills. Perceptions were investigated to determine if principals believed ...
Experimental and analytical study on two-phase impingement cooling with and without electric field
(University of Missouri--Columbia, 2007)
Among the thermal management solutions for power electronics, two-phase jet or spray impingement cooling are two promising candidates. In this study, electrohydrodynamic atomization (EHDA) method is used to generate spray ...
Classroom seating : applying Johnson's decision making inventory
(University of Missouri--Columbia, 2007)
Over a period of three weeks students in an introductory Parks and Recreation course were studied to determine their decision making styles, seating choice and movement. Data were collected on the first day of class to ...
A novel framework for protein structure prediction
(University of Missouri--Columbia, 2007)
Proteins are one of the most important molecules in the life processes. The structure of a protein is essential in understanding the function of a protein at the molecular level. Due to rapid progress in sequencing ...
