Like other polymers, spandex is made from repeating chains of monomers that are held together with an acid. Early in the spandex development process, it was recognized that this material is highly heat-resistant, which means that notoriously heat-sensitive fabrics like nylon and polyester are impro...
Most materials interact with their environment to some degree. (a) In case of metals, what is this phenomenon known as? (b) In case of polymers, what is this phenomenon known as? Toughness is: Identify ? '= Plastic deformation occurs in a ...
Identify a challenge you want to pose yourself. Look at the prompt again — the verb “shape” is another word that gets repeated, and it’s backed up by “learning” and “growth.” This prompt is asking about development, so you should identify an area in which you want to evolve, ...
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until… You add the borate ions to the mixture, and it then starts to connect these long strands together. They be...
Carbohydrates are built by forming bonds between small, repeating units known as sugar molecules. There are three primary types of sugar molecules... Learn more about this topic: Carbohydrates Lesson Plan from Chapter 6/ Lesson 1 17K If you're discussing nutrition, this lesson plan explores the...
To understand how Dacron is obtained from ethylene glycol and terephthalic acid, we can break down the process into several steps:Step 1: Identify the Monomers The two monomers involved in the formation of Dacron are: -
There's a lot at stake: The census determines the allocation of federal funds, to the tune of $675 billion dollars per year. That data is used to monitor and enforce equal employment opportunities under the Civil Rights Act and housing opportunities under the Fair Housing Act; to identify po...

material properties. BCP5, bearing a coil block of five repeating units of 4-vinilpyridine (4VP), leads to working devices with efficiency comparable to the solution-processed ones for the multiple PCBM-rich cores morphology displayed by the blend WPNPs. Otherwise, BCP2 and BCP15, with 2 ...
