Synthesis And Characterization Of Uranyl Dipyrrin Complexes For Environmental Applications, Duer Bolotaulo Bolotaulo
Synthesis And Characterization Of Uranyl Dipyrrin Complexes For Environmental Applications, Duer Bolotaulo Bolotaulo
Open Access Theses & Dissertations
Persistent organic pollutants (POPs) are toxic chemicals that adversely affect the health of human populations as well as the environment. The need to develop remediation methods and materials as well as understand the mechanisms in which they can degrade POPs is necessary. Furthermore, heterogeneous phase metal based catalysts in place today do not fully understand the chemistry underlying degradation processes. The proposed research seeks to synthesize and characterize uranyl dipyrrin complexes to assess and understand the reactivity of uranyl dipyrrins with pollutants. Photophysical and electrochemical techniques will be used to characterize and determine the viability of utilizing the uranyl complexes …
Removal Of Endocrine Disrupting Compounds From Water And Wastewater Using Ecofriendly Materials, Alma Lili Loya Posada
Removal Of Endocrine Disrupting Compounds From Water And Wastewater Using Ecofriendly Materials, Alma Lili Loya Posada
Open Access Theses & Dissertations
Endocrine disrupting chemicals (EDCs) are compounds considered pollutants of emerging concern. The United States Environmental Protection Agency (USEPA) defines emerging pollutants as new chemicals without regulatory status and with an impact on the environment and human health that is poorly understood. Bisphenol A (BPA) has been considered an EDC and found to be ubiquitous in the environment because of its presence in a multitude of products including food and beverage packaging, flame retardants, adhesives, building materials, electronic components, and paper coatings Currently, BPA is not regulated by the federal government in the US and waste water treatment plants are not …
Modulation Of The Physiological And Biochemical Effects Of Copper Nanoparticles In Kidney Beans (Phaseouls Vulgaris) Treated By Kinetin, Suzanne Annette Apodaca
Modulation Of The Physiological And Biochemical Effects Of Copper Nanoparticles In Kidney Beans (Phaseouls Vulgaris) Treated By Kinetin, Suzanne Annette Apodaca
Open Access Theses & Dissertations
It is imperative to not only understand the impact of engineered nanomaterials (ENMs) in edible plants, but also the interactions they have with various additives used in agriculture. In this study, kidney bean plants were grown in potting soil treated with nano copper (nCu), bulk copper (bCu), and copper chloride (CuCl2) at concentrations of 0, 50, and 100 mg/kg for 55 and 90 days. At 15 days of growth, 0, 10, and 100 μm of kinetin (KN) were applied to plants. Plant tissue samples were harvested at 55 days and seeds were reaped at 90 days. Physiological and biochemical parameters …
Study Of No2 Photolysis Rate Coefficients For The Paso Del Norte Region, Pema Wangchuk
Study Of No2 Photolysis Rate Coefficients For The Paso Del Norte Region, Pema Wangchuk
Open Access Theses & Dissertations
The photolysis of nitrogen dioxide is one of the most influential chemical processes in the formation of photochemical air pollution. In this study, we compared simulated and measured nitrogen dioxide photolysis rate coefficients (J_(NO_2 )) for the Paso Del Norte (PdN) region. The Tropospheric Ultraviolet-Visible (TUV) radiation transfer model was used to calculate J_(NO_2 ) values. The measurements of hemi-spherically integrated, spectrally resolved solar photon flux between the wavelengths 400 and 700 nm were used to obtain the photolysis rate coefficients for ã??NOã??_2. Results are presented for a selected episode on July, 2015. The work investigated the use of measured …
Effects Of Citric Acid Coated And Uncoated Cerium Oxide Nanoparticles In Tomato (Solanum Lycopersicum) Plants, Ana Cecilia Barrios
Effects Of Citric Acid Coated And Uncoated Cerium Oxide Nanoparticles In Tomato (Solanum Lycopersicum) Plants, Ana Cecilia Barrios
Open Access Theses & Dissertations
This research was performed to examine the physiological and biochemical effects of bare (nCeO2) and citric acid coated (nCeO2+CA) cerium oxide nanoparticles in tomato (Solanum lycopersicum). Plants were germinated and grown to full maturity in soil amended with 0-500 mg/kg and periodically analyzed using ICP-OES/MS and other spectroscopic and biochemical techniques. Although Ce in tissues increased as the external nCeO2 increased, there were no visible signs of toxicity. In mature plants, nCeO2 induced developmental changes and altered nutritional quality (essential elements) in fruits. On the other hand, nCeO2+CA affected fruit carbohydrate composition (sugars and starch). This study gives insights on …
