According to the mechanism proposed, liposome-grafted chains of flexible and hydrophilic polymers form dense “conformational clouds” preventing other macromolecules from the surrounding solution from interaction with the liposome surface even at low concentration of protecting polymer. The scale of ...
How Are Polymers Created? . Indeed, polyethylene – which can constitute a chain of up to 10,000 monomers – is a translucent and thermoplastic material that is often used to make plastic bottles, containers and packaging. Polypropylene, on the other hand, is harder than polyethylene (with up...
For each of the following pairs of polymers, do the following: (1) state whether it is possible to determine whether one polymer is more likely to crystallize than the other; (2) if it is possible, no What is strain energy in reference to ...
Polyolefins are a class of polymers formed through the combining of olefin monomers, also known asalkenes. Alkenes are hydrogen-carbon compounds with at least one carbon double bond. Once olefins/alkenes undergo polymerization, they link with one another to form a polyolefin. Polyolefins are known ...

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomerscombine with each other via covalent bonds to form larger moleculesknown as polymers. In doing so, monomers release water molecules as byproducts. ... In the process a water molecule is formed. ...
Specialty polymers play an increasingly important role in all stages of the enormously complex development process of new biologically active products. They widen and facilitate the discovery stage. For example, the use of solid polymer supports for automated peptide and oligo-nucleotide synthesis (the...
Shape-memory polymersShape-memory alloys sound brilliant, but they do have some drawbacks: they fatigue (break after repeated deformations) much more readily than ordinary stainless steel and they're notably more expensive to manufacture than traditional steel or aluminum alloys....
This acrylic fiber variant is composed partially of acrylonitrile, but a variety of other polymers are also used in its production. For instance, modacrylic contains a high degree of vinylidene chloride As such, fabrics made from modacrylic fiber generally have better drapability, wrinkle-resistance,...
Close to the triple point, the surface of ice is covered by a thin liquid layer (so-called quasi-liquid layer) which crucially impacts growth and melting rates. Experimental probes cannot observe the growth processes below this layer, and classical model
