Equipment Giving Opportunities
CEE has five teaching laboratories and a machining, woodworking and welding shop facility. We are reequipping and designing our labs with equipment that will allow students to be in full control of their experiments and projects. It is important that they get first-hand learning experience designing and producing the experiments and projects. Introducing new equipment will make course labs and student team projects a more manageable and effective for our students.
CEE Equipment List
Below is a list of equipment which would enhance our learning environment. You can fully support, or make a partial contribution towards any of these items—no gift is too small. Please specify the piece of equipment you'd like to support in the "special instructions" box.
A document camera is a visual presenter device that allows objects to be displayed to large audiences. It is used for real-time image capture and is able to magnify and project the images of actual three-dimensional objects as well as transparencies.
3-D printers would be used in a lab course aimed at giving students a knowledge base to understand the connection between various additive manufacturing (AM) processing techniques and the mechanical performance of AM metallic components. The course is relevant to those interested in understanding the origins of mechanical behavior in metallic components regardless of fabrication process.
A digital PCR would significantly enhance the workflow efficiency of student research employing molecular microbiology techniques to study microbial contaminant transformations in the environment. Molecular biology work is typically labor-intensive so research outcomes are often limited by the amount of time students can spend in the laboratory. This cutting-edge technology which can run thousands of PCR reactions in parallel will help to overcome those traditional limitations. Student research topics will include biotransformation of arsenic in soil environments and biological denitrification in technologies designed to mitigate nonpoint source nitrogen pollution from urban or agricultural environments.
An isotope analyzer would enable students to employ stable isotope techniques to track the flow and transformation of nitrogen in the environment. This piece of equipment will greatly enhance undergraduate and graduate student research exploring linkages between water quality and climate, since efforts to remove nitrogen from nonpoint source pollution often use engineered denitrification systems, which can produce significant amount of N2O as a byproduct. Additionally, it will support teaching and research to optimize engineered denitrification systems to improve water quality while minimizing climate impacts.
A cytometer is used to count all bacterial cells in a drinking water or surface water sample. Conventional methods require plating and incubation that takes days—flow cytometry gives more complete data in just two minutes. It is a state-of-the-art technique for drinking water quality measurement. This piece of equipment would significantly improve our teaching and research capabilities and efficiency.
To be used in the Environmental Processes Teaching Lab, this equipment is used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. The gaseous compounds being analyzed interact with the walls of the column, which is coated with a stationary phase. A total of four chromatographs is preferred.
This drill is stronger and more accurate than the 40-year old drill presently in the Bovay Laboratory. It would allow lab users to more safely and accurately build testing equipment and specimens, and members of student project teams to more accurately prototype their ideas. The Engineers for a Sustainable World (ESW) Automated Composting System, ESW Wind, Hydro Power, Automated Irrigation System, Piezoelectric Generator, and Solar Powered Refrigeration Teams could better connect their turbines to generators and vice versa.
A SawStop is a fantastic professional table saw that puts safety first. It allows safe cutting of large wood and plywood sheets for prototyping project team ideas and implementing testing. Many of the student projects require building cabinet-like enclosures; this saw will allow properly trained students to safely and more accurately cut the larger wood sheeting needed for these enclosures. The Solar Food Dryer, Solar Kiosk, ESW Wind, Piezoelectric Generator, Automated Irrigation system, Aquaponics, and Solar Panels Project Teams are all building structures this semester that would be easier and safer to build with a better table saw.
This machine provides versatility to make one, or multiple pieces, for one-of-a-kind custom made parts. For student project teams, this machine gives students the flexibility to design and fabricate complicated pieces that would otherwise be impossible to reproduce in our shop. For example, this year the Steel Bridge Team had complex connections that required expert assistance to fabricate with the equipment available in the CEE machine shop. The Bridgeport CNC (computer numerically controlled) Milling Machine allows trained users to write detailed programs that guide the machine to produce accurate and consistent parts in a timely manner, thus helping to meet deadlines and be more competitive in future ASCE events.
Students would benefit from the use of a tool room lathe that has threading capabilities. This machine is particularly noted for its accuracy in fabricating precision parts, thus saving time and money, as opposed to purchasing custom made components from an outside vendor. Having a tool room lathe would allow student teams to design and fabricate more intricate parts to meet budget restrictions and time constraints.
A new controller will allow set up and testing of large, complex experiments in the Bovay Laboratory for a variety of research projects and project teams, under guidance of laboratory staff. The controller would allow dynamic testing of mechanical structures and prototypes for the student projects. The EERI team uses a small shake table that can only perform sinusoidal excitations. Several courses use a small structure mounted on a shake table for design testing and analytical input. This controller would allow exciting a small shake table with representations of real earthquake ground motions.
Students on the Steel Bridge Team will use the horizontal band saw to cut metal stock accurately and with precision each time. This is important factor in building a complete bridge.
CEE Student project teams work with a variety of materials that often needs to be cut. The bandsaw produces a uniform cutting action as a result of an evenly distributed tooth load. This Bandsaw would be used for woodworking, metalworking, or for cutting a variety of other materials. They are particularly useful for cutting irregular or curved shapes, but can make straight cuts.
The Wrist Action Shaker would be a great resource for our students in the environmental teaching laboratory. It duplicates the swirling action of hand mixing. It defines reliability, versatility, and efficiency of design. An adjustment arm controls the amplitude and agitation of shaking from 0 to 15 degrees arc; shaker operates at 385 oscillations per min (+/- 10%). The shaker has a built in timer to operate from 1 to 60 min or can be set at continuous operation.
An incubator shaker will allow students in environmental engineering the ability to explore chemical reactions, biochemical reactions, and microbial growth under carefully controlled conditions. The incubator shaker provides a constant temperature to enable precise measurements of reaction rates and to provide optimal conditions for microbial growth. Likewise, the incubator shaker has a variable speed orbital shaker that allows reaction and microbial growth media to remain completely mixed during the course of the experiment. Students interested in chemical processes in drinking water treatment, microbial processes in wastewater treatment, or related environmental processes will benefit from having access to this instrument.
This piece of equipment will allow us to weigh several kilograms or just a few milligrams. It is important that students and faculty be able to achieve reliable analytical results. Quite a bit of time is spent preparing samples. Weighing solutions will ensure accurate results; this is necessary because any error in sample preparation will be simply perpetuated, or magnified, in downstream processing.
A microcentrifuge is an essential component in an environmental engineering lab. A microcentrifuge is used in separate phases of complex samples by using a rotor and centrifugal forces to separate sample components by density. A microcentrifuge is an ideal instrument to separate microbial cells from water or wastewater samples, isolate pure bacterial cultures, and to separate biological macromolecules such as DNA, RNA, and proteins. Students interested in biological processes in environmental engineering will benefit from having access to a microcentrifuge.
