Tri-State Mining District, Ecological System, And Human Health: Systematic Literature Review Analysis, Jihyun Jane Min

Posters

Objective: Although extensive research exists on corrosive environments in the Tri-State Mining District (TSMD), there has been a lack of research on how such harmful effects in the TSMD could affect residents living in those areas. However, quite recently, such research regarding relationships between the health conditions of low-income residents and toxic elements in TSDM began to grow. Therefore, the increase of empirical studies means greater complexity of the findings that require a more intricate understanding.

Methods: To meet the necessity of the study, this research was conducted by an extensive systematic review of the literature on the harmful effects …

Posters

The global energy crisis and environmental pollution have stimulated increasing attention to developing clean and renewable alternative energy sources. One of the most efficient and greenest energy storage devices is supercapacitor which could store energy via electrical double layer and redox reactions. Supercapacitors are widely employed for many portable electronics and hybrid electric vehicles due to their high-power density, fast charge-discharge rate, and good cycle stability. In this work, 3D nanostructured flower-like iron-nickel sulfide was synthesized on the nickel foam using a facile hydrothermal method. The iron-nickel sulfide electrode showed out­standing performance for supercapacitor with a high areal capacitance of …

Nanosheets Of Cuco₂O₄ As A High-Performance Electrocatalyst In Urea Oxidation, Camila Zequine, Ram K. Gupta, Pawan K. Kahol

Posters

The urea oxidation reaction (UOR) is a possible solution to solve the world’s energy crisis. Fuel cells have been used in the UOR to generate hydrogen with a lower potential compared to water splitting, decreasing the costs of energy production. Urea is abundantly present in agricultural waste and in industrial and human wastewater. Besides generating hydrogen, this reaction provides a pathway to eliminate urea, which is a hazard in the environment and to people’s health. In this study, nanosheets of CuCo₂O₄ grown on nickel foam were synthesized as an electrocatalyst for urea oxidation to generate hydrogen as a green fuel. …

Hydrogen is considered one of the cleanest energy sources. Water spitting is one of the efficient ways to produce hydrogen as a fuel at the industrial level. Water splitting via electrolysis requires an efficient electrocatalyst to reduce the voltage required for water splitting. Currently, precious metals such as platinum are considered as one of the most efficient electrocatalysts for hydrogen production via electrolysis of water. The current challenge is to find a cost-effective alternative for this process. Molybdenum and carbon are low cost and abundant mate­rials which could be used for the synthesis of cost-effective electrocatalysts for hydrogen production. In …

The highly efficient electrochemical hydrogen evolution reaction (HER) provides a promising way to solve energy and environment problems. In this work, various transition metals (Fe, Co, Ni, Cu, Ag, and Pt) were selected to support on molybdenum carbides by a simple organic-inorganic precursor carburization process. X-ray diffraction (XRD) analysis results indicated that the ß-MO₂C phase was formed in all metal-doped samples. X-ray photo­electron spectroscopy analysis indicated that the binding energy of MO₂+ species (MO₂C) shifted to a lower value after metal was doped on the molybdenum carbide surface. Comparing with pure ß-MO₂C, the elec­trocatalytic activity for HER was improved by …

Detection And Filtering Of Landmark Occlusions Using Terrain Spatiograms, Damian M. Lyons

Posters

A team of robots cooperating to quickly produce a map needs to share landmark information between team members so that the local maps can be accurately merged. However, a landmark visible to one robot may be partially occluded to another! Terrain Spatiograms are a landmark representation in which the image spatial information relates to the scene rather than the image. This makes it possible to identify and filter potential landmark occlusions. We present an approach to identifying and filtering occlusions using Terrain Spatiograms, and we report experimental results on 20 landmark datasets for varying states of occlusion. We show that …
