Synthesis and characterization of ester-free poly(trimethylene carbonate) bearing long-alkyl moieties and its degradation Various lengths of alkyl chains, like -C8H17to -C20H41, were introduced into trimethylene carbonate (TMC) to enhance the physical properties of ester-free poly(trimethylene carbonat...
Electrochemical energy storage devices are becoming increasingly important to our global society, and polymer materials are key components of these devices. As the demand for high-energy density devices increases, innovative new materials that build on the fundamental understanding of physical phenomena and...
Polymersconsist of long molecular chains of covalently bonded atoms. 高聚物都是由共价链联接原子而形成的长链分子所组成. 辞典例句 Humic acids are usually regarded aspolymersof aromatic compounds. 腐殖酸通常被看作是芳烃化合物的聚合物. 辞典例句
Ordered Organization of Long Chain Polymers: Advances andChallenges Due to the long chain character and entanglement feature,polymer chains were initially believed incapable of organizing into ordered structures. However, X-ray studies in ...
Carbohydrate polymers, on the other hand, are long chains of carbohydrates linked together through chemical bonds. In this article, we will delve into the intricaciesof carbohydrate polymers, their various types, applications, and potential future developments. Types of Carbohydrate Polymers: 1. Starch...

A survey is given of how these indices can be determined from the experiments, how they are interrelated, and how they are connected with the LCB structure and the number of long side chains. The complications occurring with samples polydispersed in molar mass and in degree of branching are ...
What are long chains of Carbon Molecules called A) Ribosomes B) Hydrocarbons C) Polymers D) None Carbon-Based Lifeforms: The element carbon is very popular in chemistry. Carbon can form numerous molecules because of its valency (having 4 electrons in the out...
However, microbial infection delays wound healing process, and novel antimicrobial wound dressings are urgently needed. Here, agarose oligosaccharides (AGO) obtained from marine red algae were used as a reducing and stabilizer for green synthesis of silver nanoparticles (AgNPs), and further successfully...
Resorbable, implantable bioelectronic devices are emerging as powerful tools to reliably monitor critical physiological parameters in real time over extended periods. While degradable magnesium-based electronics have pioneered this effort, relatively sho
