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.

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

Analyze Samples in the Lab or Field with this New Portable Fluorescence Spectrometer

PROBLEM: 1.) Important science topics are sometimes not addressed in high schools because spectroscopy instruments are too expensive to purchase and maintain  2.) Field technicians have to take water and soil samples to a lab for spectroscopy analysis, adding time and complication  3.) Valuable data is not available from remote sensors due to spectrometer power and durability limitations.

SOLUTION: A portable, durable florescence spectrometer that costs 50% less than comparable instruments in most applications due to its novel design and simple components.

Composite Roof Panel System

DEVELOPMENT PLAN:  Undetermined.  Has been successfully demonstrated, but on hold given the current downturn in construction.

Environmentally Friendly Adhesive Bonding for Composites, Pollutant Remediation, and Dye Decolorization

PROBLEM: Environmentally friendly methods are needed to bond wood products and other composites without formaldehyde. Organic pollutants and dyes from textile and paper plants in industrial wastestreams need remediation.

SOLUTION: Using the chemically enhanced Fenton system, dyes can be remediated quickly in an environmentally safe manner. Natural lignin from wood residues can be activated to produce an formaldehyde-free adhesive system and organic pollutants in waters or soils can be broken down.
