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 protective...
The formation of polymers from monomers occurs as a result of reactions, and the breakdown of polymers into monomers occurs as a result of reactions. Under what abiotic conditions can monomers spontaneously form polymers? a. When water evaporates from a hot surface. b. When ribozymes are present...
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...
What is addition polymerisation? Ethylene and propylene are in such high demand as gases due to their importance to the creation of polymers. 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...
2. Formation of Polymers: - When monomers bond together, they can do so in a linear (chain) fashion or in a branched or cross-linked manner. - In a linear arrangement, monomers connect end-to-end to form a long chain. - In a cross-linked arrangement, monomers connect in a way that...
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 ...
A plastic is any material that can be shaped or molded into any form -- some are naturally occurring, but most are man-made. Plastics are made from oil. Oil is a carbon-rich raw material, and plastics are large carbon-containing compounds. They're large molecules called polymers, which ...
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 balance between form and function is crucial in determining individuals’ overall satisfaction and confidence in their chosen clothing. Based on these three themes-perceived quality, perceived value, and sensory comfort-we can gain a more comprehensive understanding of consumers’ psychological and ...
