How to pronounce “polymers” in English

The polymers realign and the wiggle unfolds.

Most polymers have a linear degradation profile, so if the well temperature's a few degrees off, it will degrade too quickly or too slowly.

lightweight polymers that you can use for netting and all and long lines and so forth so what happened in the late

- But the polymers aren't stretched out from end to end like that.

- As you stretch the polymers, they start to align and stick together through weak intermolecular forces called Van der Waal's forces.

The longer polymers also break down much more slowly, so the wound has enough time to heal before the glue starts releasing toxins into the body.

These longer polymers can absorb stress better than shorter chains, meaning the glue can flex more without breaking.

And these polymers are plastics that can change shape and stiffness at different temperatures.

A lot of polymers, when they get really cold, get really hard and stiff.

And nitrocellulose is made by taking cellulose polymers, say from cotton or wood pulp.

But there are not big polymers of nucelobases.

And so with our background in understanding polymers and polymer physics, we've focused on printing isotropically tough parts, and have found really neat ways to chemically

We can focus our understanding on polymers, on interfaces, and really use this as a core facility to process complex electronics onto shape-changing plastics.

problem as related to how polymers and metals stick together.

There's a lot of self-healing polymers that are used right now as ship sealants, for example.

actually make it really difficult to build up those polymers.

What we don't see in meteorites are polymers.

So what we can do is we can replace polymers where you'd normally use rubbers, nylons, for a host of different markets

So the question was whether the shape memory polymers would fatigue as you're bending them over many cycles.

So here's another little video of one of these polymers that's been trained to coil around a nerve.

Because over time, all those polymers slowly slide past each other.

When they're packed tightly enough, the polymers freeze together in thin sheetlike crystals aligned in the direction you stretch.

And as you keep pulling, more and more polymers join the crystal structure.

Super glue polymers are almost all single chains running linearly between the surfaces.

The second tenet is that the combination of these small molecules forms larger molecules called polymers.

We've developed a new kind of 3D printer to make our polymers, following a process called SLA or stereo lithography.

Here's a little business card made out of one of the shape memory polymers.

So a lot of this engineering we've done in designing these shape memory polymers is similar to the problems that we face in the 3D printing world.

So my background comes in this class of materials called shape memory polymers.

And this turns out to be an excellent analogy to the way certain polymers hold each other together.

If you think about it, all of these synthetic polymers come from that initial thought process that we can't get natural rubber,

- The reason the two curves are different is because it takes more energy to align the polymers than it does for the polymers to curl back up.

In that case, all that force is on a few polymers, so the chains break one by one like a zipper unzipping.

- After mixing the glue and initiator into the acetone, the mobile polymers are able to form even longer, more stable chains than usual.

So with a wok, you generally don't have to build up polymers, and your goal shouldn't be to do that because they're going to generally end

They're found in meteorites, but we don't have proteins or very complex polymers of amino acid in meteorites.

So basically, how these little groups hanging off of our main chain polymers interact with each other to make things stronger, to make them stiffer,

So broadly, what we do is we design these materials called shape memory polymers.

So in this case, these thiol ene acrylate shape memory polymers that we've built, which have a CTE of almost 70 parts per million,

So this is the cellulose polymer, and like all simple polymers, it's repeating unit over and over again.

He's a polymer chemist at Dow Chemical, and what he developed was the polymers to go from oil based paints to acrylic based paints.

old as a concept it's you know the invention of consumerism and the invention of complex polymers equals garbage

Well when I first gave lectures and on the work we did on slowly releasing these large molecules from polymers and we first published this work pretty much everybody in the scientific

They’re actually going to look more human because of advances in material sciences from electroactive polymers to silk skin to air muscles and other such things.

You know, how much do you know about these particular polymers you’re working on.

delivery agents are the other um sort of arm of of research into RNAi delivery encapsulating RNAs in lipids in polymers.

connection was really between, um, biological polymers, the things that

- So after you've dried out the latex, you're left with raw rubber, a jumble of all these polymers.

So when you pull on a piece of rubber, first, all the polymers line up but then, each chain also unfolds.
