"The Impact of Water Vapor on Thermal Desorption Gas Chromatography"

Wednesday August 23rd, 2017 at 4:00 PM in Chemistry A101

Volatile organic compounds (VOCs) pose significant environmental effects by promoting the production of tropospheric ozone and secondary organic aerosol. Isoprene is a VOC that accounts for 44% of the annual global VOC flux.1 Atmospheric concentrations of VOCs are low, often in the sub-ppb range.1 Analysis of these compounds through gas chromatography (GC) requires preconcentration, often […]

"Defect Mediated Energy Transfer from Semiconductor Nanocrystals to a Molecular Probe"

Wednesday August 23rd, 2017 at 4:00 PM in Chemistry A101

Solid surfaces have defects such as vacancies, interstitial atoms, and impurity atoms that affect their chemical reactivity. For catalysis applications, it is important to understand how the location and nature of the surface site impact the catalytic rate. However, it is challenging to determine directly the location and chemical or physical nature of surface defect […]

"Methods of Isotopic Mass Spectrometry for Analysis of the Permian – Triassic Extinction Event"

Wednesday August 30th, 2017 at 4:00 PM in Chemistry A101

Literature Seminar abstract A particular time frame of interest to geochemists is the period from the Late Permian to the Early Triassic, as that time frame includes the End-Permian extinction event that occurred around 252 million years ago, the largest known mass extinction event in earth’s history. However, the exact cause of this extinction is […]

"Analytical Techniques Used to Study the Solid Electrolyte Interface of Lithium-Ion Batteries"

Wednesday August 30th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract Lithium ion batteries (LIB) have applications throughout our society from portable electronics to grid storage.  When a LIB is charged, the change in voltage is so great that the electrolyte of the battery undergoes parasitic reactions, forming a solid electrolyte interface (SEI) on the anode surface.1 Altering the SEI composition, which can […]

"Voltage Scanning As Trace Gas Calibration Method For Chemical Ionization Mass Spectrometry"

Wednesday September 27th, 2017 at 4:00 PM in Chemistry A101

Literature Seminar abstract Gas-phase measurement techniques are key to understanding the chemistry of atmospherically relevant compounds, such as volatile organic compounds (VOCs) and oxidized nitrogen species. Time-of-flight chemical ionization mass spectrometry (ToF-CIMS) paired with iodide (I–) chemical ionization (CI) is useful for gas-phase atmospheric measurements—providing a high degree of sensitivity, selectivity, and time resolution. Iodide […]

"Development of Point-of-Care Biosensors for Diagnosing Tuberculosis"

Wednesday September 27th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract Tuberculosis (TB) is a pulmonary disease ranking among the top ten causes of death worldwide.1 The vast majority of cases are in low- to mid-level income countries where a laboratory for nucleic acid amplification tests (NAATs), the current recommended diagnostic technique, may not be feasible due to cost and training requirements.1 With […]

"Electrochemical Aptamer-Based Techniques for Direct Analysis of Whole Blood"

Wednesday October 4th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract The ability to detect and quantify drugs, biomarkers, and metabolites in whole blood is important to further understand and monitor human health. Detecting these molecules in whole blood is a challenge because blood is a complex mixture difficult to analyze for specific components in a generalizable way without batch processing. Electrochemistry is […]

"Applications and Method Development of LC-MS for Detecting Contaminants Taken Up by Plants Irrigated with Treated Water"

Wednesday October 4th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract Irrigating agricultural crops with treated wastewater provides a cheaper and more sustainable alternative to traditional irrigation practices. However, many water quality standards for the use of treated wastewater containing environmental organic contaminants are unavailable. Most recent studies providing details of plant uptake of organic contaminants through irrigation with treated water are crop […]

"SERS as a Novel Transducer for Nucleic Acid Detection: a Proof of Concept for Point-of-Care Analysis"

Wednesday October 25th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract Nucleic acid hybridization is a phenomenon of great interest to bioanalytical chemists. High specificity of sensor-analyte coupling offers selective detection with low interference, and the unique sequences found in specific cells allows an almost limitless number of bioanalytical questions to be answered by changing the target sequence.1 While established techniques such as […]

"Improving Bacterial Diagnostics in the Age of Antimicrobial Resistance"

Wednesday October 25th, 2017 at 4:00 PM in Chemistry A101

Literature seminar abstract Antimicrobial resistance (AMR) is the ability of a bacterial strain to resist the effects of an antimicrobial drug. Due to continued overuse of antibiotics in clinical and agricultural settings, AMR is predicted to be the number one cause of death worldwide by 2050 unless significant changes are implemented.1 As antibiotic resistant strains […]
