Special emphasis is placed on the application of epoxy-based chain extenders in biodegradable polymers, such as polylactic acid (PLA), and their subsequent influence on the structural and performance ...

A method of assigning formal charges from counting “attachments” for visual inspection is introduced as part of the iterative portion of constructing Lewis electron dot structures. An “attachment” is ...

The Lewis Structure explorer was designed to give students real-time feedback while drawing Lewis Structures with a digital interactive tool, Figure 1. The interactive provides visual feedback using ...

Calculating bond order from Lewis structures is a straightforward process that helps us understand the stability and strength of various molecules. Following the steps outlined in this article, you ...

Lewis structures, also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in ...

Production pathways At commercial scale, propionic acid can be produced through three main routes, including oxidation of propionaldehyde, depending on which raw starting materials are used. Propionic ...

Initial properties that can be determined only with an atomic resolution structure, in the context of an amino acid sequence, or that depend only on amino acid identity are denoted at left. This ...
