Label-Free Surface-Enhanced Raman Spectroscopy-Linked Immunosensor Assay (Slisa) For Environmental Surveillance, Vinay Bhardwaj Oct 2015

Label-Free Surface-Enhanced Raman Spectroscopy-Linked Immunosensor Assay (Slisa) For Environmental Surveillance, Vinay Bhardwaj

FIU Electronic Theses and Dissertations

The contamination of the environment, accidental or intentional, in particular with chemical toxins such as industrial chemicals and chemical warfare agents has increased public fear. There is a critical requirement for the continuous detection of toxins present at very low levels in the environment. Indeed, some ultra-sensitive analytical techniques already exist, for example chromatography and mass spectroscopy, which are approved by the US Environmental Protection Agency for the detection of toxins. However, these techniques are limited to the detection of known toxins. Cellular expression of genomic and proteomic biomarkers in response to toxins allows monitoring of known as well as …


Effect Of Fibre Blend Ratios On Yarn Properties, Innovative Research Publications Irp India, A. Ghosh, M. Raihan Apr 2015

Effect Of Fibre Blend Ratios On Yarn Properties, Innovative Research Publications Irp India, A. Ghosh, M. Raihan

Innovative Research Publications IRP India

Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than their individual yarn properties. Different proportion of flax and polyester has been tested to observe the yarn properties and it is found that polyester was perfectly fits with low proportion of flax. Their blends with specific ratios exhibit excellent properties …


An Evaluation Of Carbon Concentrations Associated With Biodiesel Particulate Matter In An Underground Metal Mine, David Evans Apr 2015

An Evaluation Of Carbon Concentrations Associated With Biodiesel Particulate Matter In An Underground Metal Mine, David Evans

Graduate Theses & Non-Theses

Exposure to diesel particulate matter from diesel exhaust has been shown to have adverse health effects in humans. In 2012 The International Agency for Research on Cancer classified diesel exhaust as a group 1 know human carcinogen. Because of the associated health effects, there has been a strong push to reduce the amount of diesel exhaust present in the mining industry. Biodiesel is one to the more common and promising control options used to reduce the amount of diesel particulate matter that is generated during fuel combustion. The use of biodiesel over petroleum diesel has been shown to reduce not …


Characterization Of Metallic And Semimetallic Oxide Nanoparticles In Industrial Wastewater And Associated Toxicity, Gary Roth Jan 2015

Characterization Of Metallic And Semimetallic Oxide Nanoparticles In Industrial Wastewater And Associated Toxicity, Gary Roth

Legacy Theses & Dissertations (2009 - 2024)

Engineered nanomaterials (ENMs) play an increasing role in manufacturing and consumer products. Currently, there is no standard approach to studying ENM toxicity, and a growing body of literature suggests that ENMs may have toxicity differing from similar compounds in bulk or dissolved form. I examined ENMs used in the semiconductor manufacturing process called chemical-mechanical planarization (CMP) for their properties, removal in the wastewater treatment system (WWT), in-vitro toxicity, and location post-inhalation in-vivo. It was found that ENMs in CMP slurries have morphology determined by their elemental composition, but assessment of size and concentration can differ substantially between accepted techniques. Particles …
