Additive manufacturing, also known as 3D printing, is becoming a go-to production method for short production runs and rapid prototyping on a commercial scale. The growth of additive manufacturing is due to many fac­tors including development of concept modeling, product designing, prototyping, and customized parts. Pittsburg State University’s College of Technology strives to stay at the cutting edge of processing materials for additive manufacturing. The capability of making our own 3D-printer filament would allow students to work with new and different materials and would allow students to learn at the forefront of 3D printing technology.

The department of Electronics Engineering Technology (EET) of Pittsburg State University has designed a prototype of an autonomous rover to help firefighters to find lives trapped in a building during an event of fire. The rover prototype has been named CAFS, which is the abbreviated form for Civilian Acquirer for Fire Safety. This device intends to produce the first ever autonomous system to locate, record, and transmit people’s location from within a building to a user outside of the building. According to the National Fire Protection Association (NFPA), on 2017, 72% of the fire that happened in the USA ...

Under the leadership of Dr. Erik Mayer, Pittsburg State University hosted the first Kansas Solar Race Competition. The purpose of this competition is to motivate students to learn about different aspects of solar car technology. The competition motivates students by bringing multiple teams together in a friendly competition to test out their uniquely engineered and constructed wireless cars. The cars will compete in different competitions such as an agil­ity competition and a drag race. After the competition, the students are able to learn from the ingenuity of other teams and spark a curiosity to continue to learn about solar ...

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 ...

Plastic injection molding is an extremely versatile, preferred method of producing plastic parts because it is ex­tremely efficient. In the business of injection molding, it is important to have machines and tools that work prop­erly to get the job done. One such tool is the mold, which forms high quality plastic parts. The main objective of this project is to refurbish the current Frisbee mold to create promotional products for PSU’s Department of Engineering Technology. Parts were created with the existing mold to determine what issues needed to be ad­dressed, including: excessive flash on the parts ...

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 ...

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 ...

To solve the growing energy issues, significant efforts have been focused on the search of earth-abundant ele­ments that can provide multifunctional behavior for both energy generation and storage. Due to the low-cost and rich chemical nature, transition metal oxide nanostructures have been used in the fabrication of energy devices, such as fuel cells and lithium batteries. In this work, nickel, cobalt and iron molybdates were synthesized via a simple hydrothermal method in order to fabricate electrodes for oxygen evolution reaction (OER) and a superca­pacitor. FeMoO₄ required an overpotential of 294 mV to achieve a current density of 10 ...

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 ...
