Electrochemical studies, mainly cyclic voltammetry, square wave voltammetry and chronoamperometry, were carried out to study the behavior of dissolved silicon species in molten LiF-KF with additions of K2SiF6 at temperatures from 550 to 800 °C. Electrolysis experiments were run at constant current to deposit pure silicon. Working electrodes of silv...

A comprehensive year-round field campaign was conducted in the coastal city of Ningbo, China to examine the driving factors of oxidative potential (OP) of PM2.5 and hence its potential health impacts. Using dithiothreitol (DTT) cell-free assay, OP of water-soluble (OPws) and methanol-soluble components (OPmeth) of PM2.5-based samples were measured....

Particulate matter (PM) inhaled into human lungs causes oxidative stress and adverse health effects through antioxidant depletion (oxidative potential, OP). However, there is limited knowledge regarding the association between the lung-deposited dose (LDD) of PM and OP in extrathoracic (ET), tracheobronchial (TB), and pulmonary (P) regions of human...

Polycyclic aromatic hydrocarbons (PAHs) have gained attention because of their environmental persistence and effects on ecosystems, animals, and human health. They are mutagenic, carcinogenic, and teratogenic. The review provides background knowledge about their sources, metabolism, temporal variations, and size distribution in atmospheric particul...

Atmospheric lead (Pb) pollution negatively affects human health and ecosystem, and extensive research is required to identify its sources and develop robust mitigation methods. In this study, the concentration and isotopic composition of Pb in fine particulate matter (PM2.5) at five sites in the China's Beijing-Tianjin-Hebei (BTH) region were analy...

The rare earth elements (REEs) are a crucial resource frequently used as proxies for reconstructing paleomarine environmental conditions. However, there is limited understanding regarding the marine REEs cycling. In addition, the relationship between benthic diffusion of REEs and seamounts, remain unclear. Here we present the concentration profiles...

The current hydrogen generation technologies, especially biomass gasification using fluidized bed reactors (FBRs), were rigorously reviewed. There are involute operational parameters in a fluidized bed gasifier that determine the anticipated outcomes for hydrogen production purposes. However, limited reviews are present that link these parametric c...

Aluminum (Al) and its alloys are widely used in many industries, and anodic oxidation (AO) and plasma electrolytic oxidation (PEO) are two of the most important technical routes to improve their corrosion resistance and mechanical properties. This review paper covers both AO and PEO of Al alloys, in order to facilitate a comparison between the two...

Yangtze River Delta (YRD) region is located in the west coast of the Pacific Ocean and occupies a total area of about 110,915 km2 in eastern China with population of 108.6 million people (Wang et al., 2015, Cheng et al., 2014). The YRD region is one of the largest agriculture productive areas in China, producing crops such as wheat, cole flowers, c...

The ultimate goal of this research is to develop an efficient, reproducible and low cost method for analysis of VOCs in complex mixtures such as those in exhaled breath and in headspace of fungi cultures. In Chapter I; analytical methods for volatile biomarkers identification is reviewed In Chapter II, active SPME GCMS was employed to analyze VOCs...

In this greenhouse study eight (8) isolates of Macrophomina phaseolina, MP120, MP30, MP218, MP210, MP29, MP32, MP24, and MP23 isolated from soybeans grown in Mississippi were compared based on their pathogenicity potential. Soybeans (Viking 2265(OG)) were planted in pots infested with one of the eight isolates of M. phaseolina and uninfested contro...

Preparation of silicon thin films by electrodeposition using an inexpensive raw material potassium fluorosilicate (K2SiF6) has proven to be low cost method compared to the tradition way of manufacturing silicon wafers for solar cell applications. The purpose of this work is to study the effect of electrolysis parameters such as temperature of the m...

Analysis of volatile metabolites in a normal or healthy human breath was successfully carried out using a novel approach with an analytical technique that is reproducible and highly sensitive. The goal of this preliminary study was to determine whether in normal human breath intra-individual variation exist in volatile organic compound profiles. Ac...
