Synthesis And Evaluation Of Novel Silica Hydride-Based Stationary Phases For Bioanalytical Application, Seiichiro Watanabe May 2019

Synthesis And Evaluation Of Novel Silica Hydride-Based Stationary Phases For Bioanalytical Application, Seiichiro Watanabe

Most HPLC columns are packed with silanol-rich (Si-OH) type-B silica material that often participates in undesired electrostatic interactions with the analyte solutes and produces poor peak shape [1,2]. These silanols are also known to facilitate surface hydration necessary for HILIC retention mode for polar analyte molecules. However, the hydrated surface composition can easily fluctuate, and thus results in a poor reproducibility and requires lengthy equilibration step. In this study, four novel stationary phases have been developed by using the TYPE-CTM Silica Hydride material, which has replaced up to 95% of the surface silanols with silicon-hydride (Si-H) groups. One of the …

Optimizing Synthesis Of Substituted Oxadiazole Based Liquid Crystal Compounds.Pptx, Blake Bordokas Sep 2017

Optimizing Synthesis Of Substituted Oxadiazole Based Liquid Crystal Compounds.Pptx, Blake Bordokas

The liquid crystalline phase is a sensitive state of matter in which molecules exist between a solid and a liquid. Molecules in this state possess the ability to be reoriented by an electric field, which makes them extremely useful in display technology for devices such as computer monitors, smart phones, etc. A group of bent-core liquid crystalline compounds show a particularly unique type of liquid crystal phase that has promising traits which could be exploited to improve display technology. In this project we propose a simpler, more cost effective synthesis for these liquid crystals which we hope will allow us …

Collaborative Chemical Information Literacy: Is It "Scholarly?", Barbara C. Harvey Aug 2014

Collaborative Chemical Information Literacy: Is It "Scholarly?", Barbara C. Harvey

Barbara C. Harvey

This symposium illustrates a collaborative classroom activity that incorporates information literacy into an introductory chemistry course. The primary learning outcomes of the activity are to understand the peer-review process, knowing how to locate original research articles based on “clues” in a general news article, and how to differentiate between popular and scholarly periodicals. Students work in small groups in a highly-collaborative classroom setting. Each group is given a recent chemistry-related news item, and must determine how and where to find the original research article the news item is based on. Emphasis is placed on identifying original, peer-reviewed research publications. Each …
