The world is a beautiful place, but wood chips have a bad reputation.
That’s because the chips themselves are made from wood chips that are used as glue in glue-based paint, and glue-free paints are still the norm.
But in the early 1980s, scientists began to discover that the wood chips themselves weren’t making glue.
When they removed the wood chip glue from a chip, the glue dissolved and became stuck.
The result: a glue-laden chip.
It took scientists three decades to figure out why.
What they discovered was that the glue in wood chips is also the glue that makes them stick together.
But what happens to the glue as the chips age?
This has never been understood before, says John Hoey, a professor of chemistry at the University of Texas at Austin who was the lead author on the paper.
The researchers first looked at what happens as the wood is oxidized by sunlight, says Hoehy.
“We had a chemical reaction going on in the chip,” Hoeeys paper states.
“When the glue was being oxidized, the electrons were being transferred from the wood to the chip.”
When this happened, the scientists noticed that the electrons had lost their energy and were no longer available for the glue.
This loss of energy causes the glue to dissolve, and this leads to the cracking and flaking of the chip.
“It’s not as simple as putting the chip in a dishwasher,” says Hotey.
Hoeys lab was able to recreate this reaction in an electron microscope and then replicate it in a computer model.
The results showed that the chip and the glue molecules were very close together, so that when the glue dried, it was a mixture of glue and wood.
“The idea that the molecules were in a relationship of just a couple of electrons, and that they were somehow bonding, I think was the first step,” says Wernberg.
“That’s what really excited us.”
Hoeiks team has since used this model to identify the chemical structure of the glue molecule.
This is how they figured out that the chips stick together when they’re oxidized.
The molecules are actually very complex molecules, and they’re quite complex molecules that can only be seen with the light microscope.
The model also found that the bond between the wood and the chip is much more complex than the bonds between the glue and glue molecules.
In the next step, Hoeihs team has now created a new model to try to explain how this happens.
This new model is also based on a new technique, called quantum mechanical chemistry.
The new method was developed by researchers from the University at Buffalo in New York, with funding from the U.S. Department of Energy.
They developed a new chemical compound, called hydrazine, that is able to dissolve the glue, creating the same reaction in the chips.
This gives the researchers a better understanding of how the molecules actually interact with each other.
“Now we can say, okay, what is going on?” says Hoes team member Daniel Hockett.
“And we know how it happens.
The whole idea is that the hydrazines that we have in our lab are actually just the bonding of a single molecule.”
The researchers also identified a new mechanism in which the hydrosulfur compounds, which are the building blocks of the cement in a concrete slab, could be a part of the bond.
This finding will allow them to study more wood chips and the chemistry of glue.
They’re still figuring out how the hydrophobic properties of wood chip form react with water, which is the glue component of most paints.
“This is just a step in the right direction,” says Mark Osterberg, a graduate student in Hoeijs lab.
“But it’s very exciting because we have this new way to study the chemistry that makes up the glue.”
The paper has been accepted for publication in the journal Science.
“In addition to making this breakthrough, this study has allowed us to start working on a more efficient way to produce wood chips,” says John Wernbogen, a research scientist at the National Science Foundation and a co-author of the paper on hydrazone.
“There’s a lot of research to be done on the chemistry and biology of wood chips.
But we have a better way of doing that.”
