Fabrication of a Flexible Amperometric Glucose Sensor Using Additive Processes

Creator:: Du, Xiaosong, Durgan, Christopher J., Matthews, David J., Motley, Joshua R., Tan, Xuebin, Pholsena, Kovit, Árnadóttir, Líney, Castle, Jessica R., Jacobs, Peter G., Cargill, Robert S., Ward, W. Kenneth, Conley, John F., Jr., and Hermana, Gregory S.
Abstract:: This study details the use of printing and other additive processes to fabricate a novel amperometric glucose sensor. The sensor was fabricated using a Au coated 12.7 μm thick polyimide substrate as a starting material, where micro-contact printing, electrochemical plating, chloridization, electrohydrodynamic jet (e-jet) printing, and spin coating were used...

Continuous flow mesofluidic synthesis of Cu₂ZnSnS₄ nanoparticle inks

Creator:: Flynn, Brendan, Braly, Ian, Glover, Philip A., Oleksak, Richard P., Durgan, Chris, and Herman, Gregory S.
Abstract:: Copper zinc tin sulfide (CZTS) nanoparticles were synthesized using ethylene glycol as a solvent via a continuous flow mesofluidic reactor. In this study reaction temperature, residence time, and precursor concentrations were used to control CZTS composition. It was found that CZTS initially forms by the nucleation of Cu₂₋ₓS with subsequent...

Potential effects of sea-level rise on plant productivity: species-specific responses in northeast Pacific tidal marshes

Creator:: Janousek, Christopher
Abstract:: Coastal wetland plants are adapted to varying degrees of inundation. However, functional relationships between inundation and productivity are poorly characterized for most species. Determining species-specific tolerances to inundation is necessary to evaluate sea-level rise (SLR) effects on future marsh plant community composition, quantify organic matter inputs to marsh accretion, and...

Skill progression demonstrated by users in the Scratch animation environment

Creator:: Scaffidi, Christopher and Chambers, Christopher
Abstract:: The Scratch environment exemplifies a tool+community approach to teaching elementary programming skills, as it includes a website where users can publish, discuss, and organize animations that are programs. To explore this environment’s effectiveness for helping people to develop programming skills, we performed a quantitative analysis of 250 randomly-selected users’ data,...

Phenology and Productivity of C₃ and C₄ Grasslands in Hawaii

Creator:: Pau, Stephanie and Still, Christopher J.
Abstract:: Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by controlling for...

Deoxyribonucleotides as Genetic and Metabolic Regulators

Creator:: Mathews, Christopher K.
Abstract:: For more than 35 years we have known that the accuracy of DNA replication is controlled in large part by the relative concentrations of the four canonical deoxyribonucleoside 5'-triphosphates (dNTPs) at the replisome. Since this field was last reviewed, about eight years ago, there has been increased understanding of the...

Durable resistance: A key to sustainable management of pathogens and pests

Creator:: Mundt, Christopher C.
Abstract:: This review briefly addresses what has been learned about resistance durability in recent years, as well as the questions that still remain. Molecular analyses of major gene interactions have potential to contribute to both breeding for resistance and improved understanding of virulence impacts on pathogen fitness. Though the molecular basis...

Yeast POS5 NADH Kinase: Effects of a Mitochondrial Mutator Mutation on Mitochondrial Nucleotides

Creator:: Wheeler, Linda J. and Mathews, Christopher K.
Abstract:: Saccharomyces cerevisiae contains three NAD⁺/NADH kinases, one of which is localized in mitochondria and phosphorylates NADH in preference to NAD⁺. Strand et al (Euk. Cell 2:809 (2003)) reported that a yeast mutation in POS5, which encodes the mitochondrial NADH kinase, is a mutator, specific for mitochondrial genes. Because of the...

Optimally managing a stochastic renewable resource under general economic conditions

Creator:: McGough, Bruce, Plantinga, Andrew J., and Costello, Christopher
Abstract:: Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of...

Patterns of vertical distribution and migration of zooplankton at Ocean Station “P”

Creator:: Marlowe, Christopher J. and Miller, Charles B.
Abstract:: Stratified bongo net samples taken at depths between 0 and 500 m at Ocean Station “P” in the subarctic Pacific in early July 1971 have been analyzed to determine the vertical structure of the zooplankton community. Distributions for 99 categories of animals have been grouped by factor analysis into five...
