Experimental and Theoretical Studies of Nanostructured Electrodes for Use in Dye-Sensitized Solar Cells
(North Dakota State University, 2017)
Among various photovoltaic technologies available in the emerging market, dye-sensitized solar cells (DSSCs) are deemed as an effective, competitive solution to the increasing demand for high-efficiency PV devices. To ...
Mechanical and Surface Properties of Technical and Single Flax Fiber in Micro and Nano Scale
(North Dakota State University, 2017)
The continued search for sustainable and eco-friendly materials led to the integration of bio-fibers as the reinforcement in composite materials. However, a wide variation in their mechanical properties poses a considerable ...
Aerosol-Based Ultrafine Material Deposition for Microelectronics
(North Dakota State University, 2012)
Aerosol-based direct-write refers to the additive process of printing CAD/CAM features from an apparatus which creates a liquid or solid aerosol beam. Direct-write technologies are poised to become useful tools in the ...
Fine Line Metallization of Silicon Heterojunction Solar Cells via Collimated Aerosol Beam Direct Write
(North Dakota State University, 2012)
Solar energy has come to the forefront as a scalable and largely underutilized renewable energy resource. The current cost of solar electricity, namely from photovoltaics, along with other logistics factors, has prevented ...
Numerical Simulation of Direct Expansion Solar-Assisted Heat Pump Water Heater Using Carbon Dioxide as Refrigerant
(North Dakota State University, 2013)
Compared to the conventional solar-assisted heat pump (SAHP) water heating system, a relatively more compact direct-expansion solar assisted heat pump (DX-SAHP) has been introduced, in which the solar collector acts as an ...
Numerical Analysis of a PV/Microchannel Integrated CO2 Direct-Expansion Heat Pump Water Heater
(North Dakota State University, 2019)
A steady-state numerical model of a PV/microchannel integrated direct-expansion CO2 heat pump (PV-DXHP) water heater is developed, validated, and analyzed in the present study. To accomplish the objectives, a numerical ...
Longitudinal Associations among Personality, Perceived Control, and Health for American and Japanese Aging Adults
(North Dakota State University, 2019)
Perceived control is associated with health throughout adulthood, yet has also been found to decline with age possibly due to age-related experiences of increasing losses and limitations in life circumstances. Perceived ...
Longitudinal Analyses of the Sexual and Reproductive Health Knowledge and Parent-Adolescent Communication of At-Risk Adolescents
(North Dakota State University, 2017)
Despite declining rates, unintended adolescent pregnancy remains a considerable public health challenge in the United States (Hamilton, Martin, & Osterman, 2015). Unintended pregnancy leads to a host of negative outcomes ...
Weight-Related Health Behaviors and Body Mass: Associations between Young Adults and their Parents, Moderated by Parenting Styles
(North Dakota State University, 2011)
The incidence of overweight conditions among children and adolescents is a
growing national concern. Although current literature suggests that parental health
behaviors could influence health behaviors of children, studies ...
Rural Adolescents' Perceptions of Alcohol Use: A Qualitative Study
(North Dakota State University, 2012)
This qualitative study outlines rural adolescents' perceptions of the reasons they choose to use or not use alcohol. The social contextual factors that underlie their decisions are addressed. Twenty juniors and seniors ...
