Push-pull Tests to Quantify In-situ Naphthalene Phytoremediation Rates
… were performed, of which three did not include naphthalene in the injection solution, so that the developed method could be evaluated, tested, and yield an initial set of rates to make seasonal and spatial varying in-situ comparisons. Method comparison used for rate analysis found the highest …

Interactions Between Portland Cements and Carboxylated and Naphthalene-Based Superplasticizers
In the final part of this study, the relation between the concrete slumps and the paste rheology is established. However, concretes required much less superplasticizer than paste to be dispersed. The differences in the shear history between the concretes and the pastes possibly explain such …

Microplastics as Contaminant Vectors: Influencing the Bioaccessibility of Naphthalene from Freshwater
… to investigate the capacity of MPs to transfer naphthalene, a carcinogenic polycyclic aromatic hydrocarbon (PAHs), from freshwater systems to the human gastrointestinal tract (GIT). The focus was on characterizing the sorption mechanisms of naphthalene and its bioaccessibility (i.e., an estimate …

The Synthesis of Naphthalene-Containing Compounds and Materials Using Benzannulation Reactions
… or cyclized to isolate substituted ortho-naphthalenes. Through our fundamental studies into this transformation, we have shown it serves as a versatile reaction in the organic synthetic chemists toolbox to access novel aromatic architectures.

Reversible and irreversible adsorption of naphthalene and α-naphthol to soil
Experiments were performed with naphthalene and a-naphthol to compare the processes involved in the sorption of a polycyclic aromatic hydrocarbon (PAH) and its metabolite, respectively, and to assess the bioavailability of these two compounds adsorbed to two sandy soils with different organic …

Transparent-to-dark electrochromic behavior in naphthalene-diimide-based mesoporous MOF-74 analogs
The deliberate insertion of redox-active naphthalene diimide ligands in the versatile family of metal-organic frameworks known as MOF-74 (CPO-27) gives rise to a mesoporous electrochromic MOF that can be switched from transparent to dark, a desirable feature in electrochromic devices such as smart …

Study of Skin Friction and Surface Regression Interaction via the Naphthalene Sublimation Technique
This study explores the potential of the naphthalene sublimation technique to be used to analyze the manner in which surfaces regress, specifically focusing on the effect that skin friction has on regression and vice versa. For this experimentation, a flat steel plate installed with three skin …

Direct Transpiration and Naphthalene Uptake Rates for a Hybrid Poplar Based Phytoremediation System
Direct transpiration rates and plant uptake of naphthalene by a hybrid poplar phytoremediation system located in Oneida, Tennessee were determined using hydrologic and groundwater concentration data. Water table recession analysis techniques were employed to determine direct transpiration rates …

Direct Volatilization of Naphthalene at a Creosote-Contaminated Site with a Phytoremediation System
… PAHs. This thesis focuses on the movement of naphthalene through the subsurface because it comprises the majority of the creosote and evidence for its remediation exists. Of the many mechanisms within the phytoremediation system that serve to remediate contaminated groundwater and soil, the …

Studies of dichloro- and tetrachloro- adducts of naphthalene and some of its substituted derivatives
trans-1,2-Dichloro-1,2-dihydronaphthalene has been obtained as the major product of the photochlorination of naphthalene at low temperature, and is the first authentically described naphthalene dichloride. Its further reaction with chlorine, under heterolytic conditions gives, in part, a new …

Studies and Optimization of All-Polymer Solar Cells based on Naphthalene Diimide-Biselenophene Copolymer Acceptors
… all-polymer solar cells (all-PCSs) based on naphthalene diimide-biselenophene copolymer acceptors and aims to better understand the relationship between photovoltaic properties, blend morphology, and device processing variables. In this study, we found that optimal thermal annealing and use …
