Future galaxy collision predicted
CORVALLIS, Ore., April 11 (UPI) -- Oregon scientists say they've developed new health- and environment-friendly wood adhesives based on tofu and the proteins mussels use to adhere to rocks.
Kaichang Li, an assistant professor at Oregon State University in Corvallis, became curious how mussels are able to cling so strongly to rocks while being pounded by waves.
The OSU team found the clinging mussel tendrils contain a special protein with an abundant level of a phenolic hydroxyl group and an amino group. They were able to infuse easily produced soy protein with these groups, developing an organic adhesive that works on wood.
The new adhesives could be use to make wood composite panels, ranging from plywood to oriented strand board, particle board, and laminated veneer lumber products -- all major components of home construction. They could also replace current formaldehyde-based wood adhesives that are associated with some health problems, including eye and throat irritation.
Three patents are pending on the adhesives.
