Bridge in a Backpack®

auburnbridgeforweb2.jpg

The Bridge-in-a-Backpack is a lightweight, corrosion resistant system for short to medium span bridge construction using FRP composite arch tubes that act as reinforcement and formwork for cast-in-place concrete. The arches are easily transportable, rapidly deployable and do not require the heavy equipment or large crews needed to handle the weight of traditional construction materials.

To date six Maine bridges have been built using the Bridge-in-a-Backpack technology. Several bridge projects are planned for 2012 throughout New England and beyond.

3D Biplane Microscopy

A microscopy system is configured for creating 3D images from individually localized probe molecules. The microscopy system includes a sample stage, an activation light source, a readout light source, a beam splitting device, at least one camera, and a controller. The activation light source activates probes of at least one probe subset of photo-sensitive luminescent probes, and the readout light source causes luminescence light from the activated probes. The beam splitting device splits the luminescence light into at least two paths to create at least two detection planes that correspond to the same or different number of object planes of the sample. The camera detects simultaneously the at least two detection planes, the number of object planes being represented in the camera by the same number of recorded regions of interest. The controller is programmable to combine a signal from the regions of interest into a 3D data.

Zeolite Composite Materials for Waste Odor Control

A composite material for environmental odor control is useful in controlling odors from waste, for example, as an alternative daily cover for landfills and in composting applications. The composite material includes a fiber web and a zeolite containing metals to promote absorption of odorous has.

Fire Resistant Cellulose Insulation

Cellulose-fire-resistant

 

 

 

 

 

 

 

 

End users and installers of insulation want a product that is affordable, efficient and safe. Cellulose insulation, generally produced from recycled wood fiber, is affordable and outperforms fiberglass in extreme weather. But cellulose has poor insect resistance and fire retardant qualities without the addition of toxic chemicals.  Additionally, the cellulose insulation  manufacturing process currently used creates a product prone to settling, which is bad for the homeowner, and dust, which is bad for the installer.  ProCell Insulation solves all of these problems, making it a very attractive choice compared to fiberglass and other cellulose insulation brands.

The technology was developed at UMaine in collaboration with the company founders.  Company is currently developing manufacturing and distribution networks. Learn more at procellinsulation.com
