A central goal of green chemistry is to avoid hazard in the design of new chemicals. This objective is best achieved when information about a chemical's potential hazardous effects is obtained as early in the design process as feasible. Endocrine disruption is a type of hazard that to date has...
Water bodies act as chemical data loggers that contain tens of thousands of molecules that represent the sum of the biological, chemical, and physical processes occurring within a watershed. We hypothesize that unique chemical signatures present within a water sample can be informative of upstream processes. By extracting non-polar organic...
The study of the effects of diethyldithiocarbamate (DEDTC) in some diseases is in focus for many years. However, DEDTC is a metal chelator that can present neurotoxicity as side effects. Here we investigate the effect of DEDTC on brain Zinc (Zn) content and behavior. To address this issue we used...
A series of combined measurements was made at the Naval Air Station North Island (NASNI) Installation Restoration Site 5, Unit 2 during July and August 2013. Combined measurements included CO₂ respiration rate, CO₂ radiocarbon content to estimate chlorinated hydrocarbon (CH) mineralization and a zone of influence (ZOI) model. CO₂ was...
Porous substrates transport fluid via capillary action and can be inexpensive, making them ideal for field-use sensors. Direct wax printing is one of the most commonly used fabrication methods to define fluid paths in standard substrates like cellulose and nitrocellulose. However, direct wax printing is not possible for flexible materials...
ZIF-8, a zeolitic imidazolate framework that consists of zinc ions and imidazolate linkers, is of great interest due to its simple synthesis methods, low-cost raw materials, chemical and thermal stability, as well as its stability in moist environments. Furthermore, due to its unique structure, it contains well-defined pores that have...
We demonstrate a novel synthetic route to fabricate a one-dimensional
peapod-like Sb@C structure with disperse Sb
submicron-particles encapsulated in carbon submicron-tubes.
The synthetic route may well serve as a general methodology
for fabricating carbon/metallic fine structures by thermally
reducing their carbon-coated metal oxide composites.
Acenes larger than pentacene are predicted to possess enticing electronic properties, but are insoluble and prone to rapid decomposition. Utilizing a combination of functionalization strategies, we present stable, solution processable hexacenes and an evaluation of their hole and electron transport properties.
Plastic pollution is an ever-increasing environmental threat. As large-scale plastics break down to form nanoscale plastics, it is essential to investigate their effects on freshwater ecosystems. With many plastic nanoparticle (NP) studies favoring the effects of common polystyrene (PS) plastics, a gap is formed for other common plastic types like...
NMR spectroscopy is the go-to technique for determining the solution structures of organic,
organometallic, and even macromolecular species. However, structure determination of nanoscale
aqueous inorganic clusters by NMR spectroscopy remains an unexplored territory. The few hydroxobridged
inorganic species well characterized by ¹H Nuclear Magnetic Resonance spectroscopy (¹H-NMR)
do not provide...
