Dehydration and hydrolysis reactions are catalyzed, or "sped up," by specific enzymes; dehydration reactions involve the formation of new bonds, requiring energy, while hydrolysis reactions break bonds and release energy. These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class. For …
In this paper, we combined high-end cationic UV-curable material with fluorinated chain obtaining a series of new fluorine-containing aromatic oxetane monomers via a mild nucleophilic substitution reaction. The structures and properties of monomers were characterized using 1H-NMR, 19F-NMR, dynamic viscosity tests and …

High-performance fibre battery with polymer gel electrolyte
Realizing solid-state lithium batteries with higher energy density and enhanced safety compared to the conventional liquid lithium-ion batteries is one of the …
Polyimide (PI) is a kind of favorite polymer for the production of the membrane due to its excellent physical and chemical properties, including thermal stability, chemical resistance, insulation, and self-extinguishing performance. We review the research progress of PI separators in the field of energy storage—the lithium-ion batteries (LIBs), …
Introduction Lithium batteries have become an integral part of our daily lives, powering everything from portable electronics to electric vehicles and energy storage systems. Ensuring the safe and ...
Proteins and Polypeptides. Proteins are organic compounds that contain four elements: nitrogen, carbon, hydrogen, and oxygen. To comprehend the full scope of proteins, it is crucial to understand various properties, including the basic biological molecule, peptides, polypeptide chains, amino acids, protein structures, and the …
Lactic acid (LA), also known as 2-hydroxypropionic acid, is a widely distributed hydroxy acid in nature. Due to the chiral centre at its second carbon, LA has two different configurations, as L (+) LA or D (-) LA (see Table 1) [[39], [40], [41]].And equal amount of L-LA and D-LA are mixed to form racemic LA (rac-LA).The physical and …
In 2021, SES demonstrated a solid state battery, Apollo, with 107 Ah capacity and 417 Wh/kg energy density. Toyota has filed 203 solid state battery patents in the United States through 2021, the most of any company. Samsung SDI, one of the world''s top lithium-ion battery producers, has begun construction on its solid-state battery pilot …
Polymers consist of large molecules, i.e. macromolecules. According to the basic IUPAC definition (Metanomski 1999, Jones et al. 2009), ''A polymer is a substance composed of molecules characterized by the multiple repetition of one or more species of atoms or groups of atoms (constitutional repeating units) linked to each other in amounts …
1. Introduction. Transportation has significantly expanded the scope of human activities and facilitated exchanges among different countries and regions. 1 New electric energy vehicles are playing an increasingly important role in decarbonization in the transportation industry. They constitute a promising solution to a set of global challenges …
Importantly, polymers can be more than binders and electrolytes: they can also serve as active materials. The use of organo-radical, organo-sulfur, and carbonyl complexes for this purpose has been extensively reviewed.[4–6] Advantages of using polymers as battery materials include the ease of property/structure tuning by changing …
3.1: Synthesis of Biological Macromolecules
In a dehydration synthesis reaction (Figure 1), the hydrogen of one monomer combines with the hydroxyl group of another monomer, releasing a molecule of water. At the same time, the monomers share electrons and form covalent bonds. As additional monomers join, this chain of repeating monomers forms a polymer.
Employing solid-state electrolytes offers another fundamental solution to address the dissolution issue. Hanyu et al. reported a solid-state monomeric organic …
Monomers and Polymers. Monomers are molecules that can bind into long chains—these long chains are called "polymers." In other words, a polymer ("poly" = many) are made of monomers ("mono" meaning "one"). Amino acids are the monomers that comprise polypeptides (polypeptides being the polymers). A polypeptide folds into a 3D ...
Three general kinds of monomers, difunctional monomers, unsaturated monomers, and cyclic rings, can be used for polymerization. Several examples are shown in Fig. 1. Difunctional monomers such as diamines and diols are employed for polycondensation and polyaddition that involve exploitation of the functional group …
The sales of new energy vehicles in China have surged from 8,000 in 2011 to more than 3.52 million in 2021. Thus, China has globally dominated the new energy vehicle production and sales for seven consecutive years. Pure electric vehicles remain the primary type of new energy vehicles, accounting for the largest share of both production …
