Performance quality of many industrial materials depends on consistent distribution of particle sizes within the material. The ability to quantify other parameters such as surface roughness, surface area, and particle shape is also desirable. Current methods provide a static, batched measurement of limited utility. This new method and device provides real-time measurements directly from the manufacturing line flow.
This device has demonstrated performance on paper additive products with aspect ratios ranging from 2 to 8 and short axis diameters between 100 and 500 nm. Applications are in quality control.
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.
Membrane technology first developed to create artificial muscles may soon be used to improve fuel cells. Pictured above is a fuel cell membrane manufactured using this new method. Resulting surface porosity (a) and a deeply diffused conductive area (light lines in b) increase surface area available for electricity production and create a stonger, simpler, long-lasting membrane.
PROBLEM: Manufacturers of low temperature fuel cells need solutions for improving the strength, durability and manufacturability of a key component, the membrane electrode assembly, or MEA.
