This category contains lab protocols for the Michigan-Tech Open Sustainability Technology (MOST) Research Group.

A note on safety: MOST researchers never do anything you feel is unsafe. If any experiment makes you even remotely uncomfortable go to talk to Dr. Pearce about it immediately.

MOST Research Facilities[edit | edit source]

Space[edit | edit source]

The Pearce group has been allotted two rooms of research space on the 4th and 5th floors of the M&M Building at Michigan Technological University. The space consists of 2 clean hoods, 2 standard fume hoods, and bench top workspace for more than a dozen specialized pieces of equipment and work areas. In addition all metal 3-D printing occurs in 3 bays of fume hood on the 3rd floor lab.

Computers[edit | edit source]

The Pearce group laboratories are equipped with >10 Linux-based computers and >10 PC-compatible computers that run up-to-date software for word processing, graphics, engineering design and data manipulation. All computers have Internet connections though hi-speed Ethernet ports or wireless and connect to a laser printer and copier in the offices. In addition, most 3D printers in the MOST lab have a stand-alone computer/microcomputer of some kind.

Offices[edit | edit source]

All graduate students have shared office space as part of the MSE and ECE programs. Each student has a desk, which are equipped with Ethernet ports and each office has file cabinets for storage, as well as access to shared printers. The PI has an office down the hall from the main laboratory on the 5th floor with sufficient space for scientific discussions with 3 students and has access to numerous conference rooms within the building for group meetings.
