Enhancing Supercapacitor Electrochemical Performance with 3D Printed Cellular PEEK/MWCNT Electrodes Coated with PEDOT: PSS.

In this study, we examine the electrochemical performance of supercapacitor (SC) electrodes made from 3D-printed nanocomposites. These composites consist of multiwalled carbon nanotubes (MWCNTs) and polyether ether ketone (PEEK), coated with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The electrochemical performance of a 3D-printed PEEK/MWCNT solid electrode with a surface area density of 1.

Optimization of Zebrafish Larvae 6-OHDA Exposure for Neurotoxin Induced Dopaminergic Marker Reduction.

Parkinson's disease (PD) is a neurodegenerative disorder that is clinically assessed by motor symptoms associated with the loss of midbrain dopaminergic neurons affecting the quality of life for over 8.5 million people worldwide. The neurotoxin 6-hydroxydopamine (6-OHDA) has been used to chemically induce a PD-like state in zebrafish larvae by several laboratories; however, highly variable concentration, methodology, and reagents have resulted in conflicting results suggesting a need to investigate these issues of reproducibility.

Does prey availability influence the detection of Dinophysis spp. by the imaging FlowCytobot?

The Imaging FlowCytobot (IFCB) is a field-deployable imaging-in-flow cytometer that is increasingly being used to monitor harmful algae. The IFCB acquires images of suspended particles based on their chlorophyll-a fluorescence and/or the amount of light they scatter (side scattering). The present study hypothesized that fluorescence-based image acquisition would undercount Dinophysis spp.

Engineering the HK97 virus-like particle as a nanoplatform for biotechnology applications.

The research described here looks at the development of virus-like particles (VLPs) derived from bacteriophage HK97 as versatile scaffolds for bionanomaterials construction. Based on molecular models, the Prohead I HK97 VLP was engineered to allow attachment of small molecules to the interior by introducing a reactive cysteine into the genetic sequence of the HK97 GP5 protein that self assembles to form the VLP structure. In addition, methods for entrapping large protein macromolecules were evaluated and found to produce high encapsulation numbers of green fluorescent proteins (GFP) in the internal space of the HK97 VLP.

Domoic acid production by Pseudo-nitzschia australis: Re-evaluating the role of macronutrient limitation on toxigenicity.

The toxigenic diatom Pseudo-nitzschia australis (Frenguelli), isolated from the California Current System (CCS), was examined in unialgal laboratory cultures to evaluate domoic acid (DA) production and cellular growth as a response to macronutrient limitation. Toxic blooms of P. australis are common in the coastal waters of eastern boundary upwelling systems (EBUS), including those of the CCS off the west coast of the United States where limitation by macronutrients, specifically silicon as silicic acid [Si(OH)], or phosphorus as phosphate [PO], has been suggested to increase the production of DA by these diatoms.
