We weren’t familiar with the Minneapolis city flag until just recently, but were pleasantly surprised to see one of the symbols on it is a microscope. That seems fitting to us! Microscopes are one of the most important tools we use at MEE to provide our clients in the medical device, industrial and electronics industries with high-quality materials characterization for their advanced materials and critical components.

MEE has three scanning electron microscopes (and a new one coming this summer) and a light microscopy laboratory equipped with a variety of light microscopes with magnifications ranging from 5X to 2,400X.

There is a small contingent of Minneapolis citizens advocating for an update of the flag. We would hate to see the microscope image go away but either way, MEE will always be flying the microscopy banner.

Journal of Failure Analysis and Prevention

Alkaline Carbonate SCC Failures at a Refinery, co-written by MEE staff engineers, Ryan Haase and Larry Hanke was recently published in the Journal of Failure Analysis and Prevention ( First Online: January 16, 2018)

A metallurgical evaluation was performed to investigate two failures from carbonate-containing sour water service at a refinery. The paper details the visual, SEM/EDS, metallographic, and microhardness evaluations used to determine the failure mechanism for each refinery component.

 

 

 

 

 

Failure Analysis

“The greatest teacher, failure is.”

Wind Generator Blade Failure

This line from the latest Star Wars movie caught our ear. Any product failure can have serious consequences – from financial loss and/or personal safety perspectives. The expertise of the MEE engineering and technical staff encompasses a fundamental understanding of material behavior and a broad range of experience with different materials and types of failure. Paired with our technical expertise in failure analysis is an understanding that there is often an underlying root cause of failure that may be of greater importance to mitigating or preventing similar failures or improving a product’s future performance.

There is a lot to be learned from failure. MEE is your partner in the determination of the cause of a failure to minimize future risk.

Nanostructures Imaging

posted January 2018

These images are of a selective area of AlGaN (aluminum gallium nitride) nanostructures on graphene. Images were captured using the Field Emission Scanning Electron Microscope, FESEM, at MEE in support of a project partnership between CrayoNano AS of Norway and Agnitron Technology of Eden Prairie, MN USA.

The FESEM is an advanced microscope offering increased magnification and the ability to observe very fine features at a lower voltage than the SEM found in most laboratories.  Just as important as having the right tools for the job is having an experienced operator who can use the microscope to reveal the best images. Kudos to Kurt Schenk, MEE Laboratory Manager, for his work on this fascinating project.

Medical device development calls for innovation, precision and critical thinking – MEE matches your requirements with advanced materials characterization, analytical methods and experienced and informed materials strategies.

Look for us in the exhibit hall of the upcoming MD&M event November 8-9 at the Minneapolis Convention Center.  Materials Evaluation and Engineering staff will be there to meet and greet and answer any questions you might have about our services.

We will be at Booth #1304 (first booth if you enter through the central doors of the exhibit hall.)

Materials Science Camp 2017

posted June 2017

Last Friday we had thirty high school students at MEE  as part of a week-long Materials Science Camp sponsored by the MN Chapter of ASM International.  Under the direction of  industry and education based “Materials Mentors”, students got some real world experience solving a materials failure analysis project. Three of our staff, Larry Hanke, Kurt Schenk and Neal Hanke, and our summer intern, Atte were  camp mentors. This was MEE’s eleventh year sponsoring the camp.

Larry Hanke just returned from a visit to the Ottawa Chapter of ASM International. As a member of the ASM Board of Trustees, Larry has been invited to visit many local chapters. These visits are an important way to keep local chapters updated on what is going on in the organization at the national level and for the Board to hear about issues and concerns of the local chapters.  He enjoyed meeting the Ottawa chapter members and hearing about their involvement in Teacher Materials Camp.

Larry presented at the meeting a talk on Forensic Materials Engineering For Product-Reliability Litigation.  In addition, Chapter Chair, Nasseh Khodaie, arranged for Larry to take a tour of the National Research Council (NRC), the Government of Canada’s premier research organization.

Welcome to our summer intern, Atte Kadoma. Atte just completed her freshman year at Iowa State University where she is working towards a degree in Materials Engineering. We first met Atte in 2014 when she attended ASM-MN Materials Camp as a high school student.  MEE is a corporate  sponsor of Materials Camp and the students spend a day here getting hands-on experience in a materials testing laboratory.  We even found a photo in the Materials Camp photo archives of Atte at the Rockwell hardness tester!

Atte has long been interested in pursuing an engineering degree but said her experience at Materials Camp definitely influenced her decision to choose materials science engineering as her major. She has expressed a particular interest in failure analysis.

We were very pleased to be able to offer Atte an internship this summer and look forward to working with her.
