Smart Materials Laboratory
The Smart Material Lab (SML) in the University of North Texas (UNT) is focused on design, analysis, and experiments for piezoelectric devices used for sensing, energy harvesting, and structure health monitoring applications. This group has conducted research in high-temperature material test methodology, modeling and experiment of novel sensing and energy harvesting mechanism, and structure health monitoring in harsh environments. The technology we have developed addresses critical national needs in the monitoring of power plants, manufacturing process and control, aerospace propulsion systems, oil and gas exploration, and other applications. The group’s research is funded by National Science Foundation (NSF), Army Research Office (ARO), Department of Defense (DoD), Department of Energy (DoE), Peterbuit, US Army Natic Program, USDA and UNT. Room: F179
Research in the thermal laboratory focuses on projects such as the latent heat thermal energy storage (LHTES) system using phase change materials (PCMs) for large-scale electricity generation in concentrated solar power (CSP) plants. Research is also being done into high-temperature PCMs (melting points above 700 °C) combined with graphite foam to significantly increase the effective thermal conductivity, and therefore, enhance the heat transfer performance in the LHTES system. Researchers are also investigating on dispersing nanoparticles in the PCMs to improve the latent heat of fusion. Another area being researched is the efficient thermal control technologies for the power electronics heat removal in hybrid electric or all-electric vehicles, i.e., use of vapor chamber combined with high thermal conductivity graphite foam to enhance the heat spreading, studying on a novel jet impingement configuration to enhance the heat removal capacity. Room: F102C
Small Scale Instrumentation Laboratory
The Laboratory of Small Scale Instrumentation (LSI) has been served for several research projects including thermal characterization of one dimensional, two dimensional and three dimensional materials. One dimensional materials are carbon nanotubes, boron nitride nanotubes, and silicon carbide nanowires. Their thermal conductivities were characterized by using either 3-omega or thermal conductance method. Recent advances in micropipette-based thermal sensors have been used to measure thermal conductivities of 2D materials such as graphene and carbon nanotube thin film. We are extending this technology to characterize fluid thermal properties and furthermore cellular level thermal conductivities (3D). In the LSI we are also conducting research related with 3D manufacturing as a recently awarded NSF-funded project. In addition, one PhD student is working on simulation of membrane mass transfer that may provide important data to develop a membrane heat pump system. Room: F102E
Composites Preprocessing Laboratory
This lab is used for fabrication and study of bio products which can include wood products, bio composites, activated carbon, and any materials made from renewable resources. The lab is used to prep materials and construct composites. Currently in the lab is a concrete tester, a differential scanning caloromiter, a plasma etcher, and some other equipment most of which is used to characterize the material properties of what is made in the lab. Most characterization is specific to properties that are important most bioproducts. A seconday Lab to this space is D140 where this lab is stores the large box furnace, tube furnace, large universal testing machine, and wind tunnel senior design project. The furnaces are used to activate materials into complex carbon structures or modify materials with heat treatments. Much of the research done in D140 is linked to lab D144. Room: D144
Composites Characterizations Laboratory
This lab is used for material characterizations including, mechanical properties, thermal, acoustic, electrical, surface properties, specific surface area, and porosity, biodegradability, flammability, and etc. This lab contains a large amount of equipment which is used to determine the properties of the different materials that are brought to our department or made within the department. The lab includes universal testing machine that can determine the mechanical properties, various machines that can determin surface area, there is a composter that is used to determine the gasses produced by a material that is undergoing decomposition which can measure how biodegradable a materials is and it is only one of a few in the southern united states. Room: D126
Air Quality Research Laboratory
This lab is used in support of field-based environmental monitoring of air pollutants. Measurement of environmental contaminants in the ambient atmosphere and indoors is conducted using state-of-science compliance grade monitors for ozone, fine particulate matter, oxides of nitrogen, carbon monoxide, carbon dioxide, volatile organics and toxic compounds. In addition, meteorological parameters are measured using weather stations. Routine testing and calibration of monitors are performed here. The lab is also used for the development and evaluation of low-cost and low-energy portable sensors for measurement of environmental para-meters including concentrations of air pollutants in the ambient atmosphere. Room: F177
Biosensing and Bioenergy Laboratory
Dr. Reid develops and characterizes electrode materials and devices for bioenergy harvesting and biosensing applications such as biofuel cells and biosensors. Performance of these devices is highly affected by mass, electronic, and ionic transport through the electrode materials as well as at the liquid-electrode interface. By understanding these key factors, Dr. Reid hopes to develop new and improved ways to utilize and monitor bioenergy sources. His current interests include mechanical energy harvesting through reverse electrowetting, electrochemical detection of traumatic brain injury, and multifunctional sensing/energy harvesting devices. Common themes among many of Dr. Reid’s previous projects are 1) accessing untapped bioenergy sources within us and in our surroundings and 2) combining multiple functionalities into a single material or device. These themes can be seen in examples of previous research projects: a contact lens biofuel cell, a self-powered lactate sensor, and composites that have active surface roughness control. Room: F102A.1
Thermal Fluid Computational Laboratory
The MEEN Thermo/Fluid Computational Lab (TFCL) provides researchers with top-of-the-line computational software and hardware. The student and faculty researchers are developing improved computational modeling techniques and design tools open to collaborators in both industry and academia.

Between Dr. Sadat and Dr. R. Zhang, they share thousands-CPU dedicated cores to ensure express development of simulations. Funding has been supported by Office of Naval Research. Room: D206B
Zero Energy (ZØE) Laboratory
The Zero Energy (ZØE) Research Laboratory is a unique kind of building in Texas – designed specifically to test and demonstrate various alternative energy generation technologies in order to achieve a net-zero energy consumption of energy. The net-zero energy philosophy is based on a combination of different renewable energy technologies in a building (such as solar, geothermal, and wind systems) which leads to produce enough energy to power a building and in many cases even create excess energy to power a building and in many cases even create excess energy to return back to the power grid and thus the net energy consumption over a period or a year becomes zero. The lab is over 1,200 square feet and has an open flexible work/laboratory space along with an attached work shop area. There is a living quarter with a bathroom and a small kitchen with a refrigerator. Steel columns/beams were used for building as well as structural insulated panels for the walls and roof. It has a centered utility core for easy operation and remodeling. The sustainability features include: bamboo flooring and millwork, local materials, a recycled glass counter top and back splash, a rain-harvesting water system, and renewable solar and wind power for energy.
The Manufacturing Lab is used for the class 3100 Manufacturing Processes as well as the capstone design classes. Students will study the manufacturing processes and their capabilities, analysis and economics. Study of the fundamentals of engineering processes in manufacturing as related to design and production and materials properties. Traditional and non-traditional manufacturing process and selection optimization.

Senior Design is the capstone undergraduate design project of the Department of Mechanical and Energy Engineering. Seniors are able to apply their knowledge and showcase their abilities through the completion of challenging, real-world design problems.
