Researchers compared three different drug delivery models based on ionic liquids. Scientists have developed a powerful API-IL concept to access structural diversity and dual-action pharmaceuticals.

Electron-pair bonding is a central chemical paradigm. Here, we show that alongside the two classical covalent and ionic bond families, there exists a class of charge-shift (CS) bonds wherein the ...

Understanding the behavior of materials at their interfaces — where they connect to and interact with other materials — is central to engineering a variety of devices used to process, store and ...

AN attempt 1 to resolve misunderstandings regarding ionic-covalent bonding in solids has been criticized in a recent article by Mooser and Pearson 2. It should be pointed out, however, that their ...

The chemical bond is defined, and students learn to distinguish between ionic and covalent Introduction to Bonding: The chemical bond is defined, and students learn to distinguish between ionic, ...

The drug ibrutinib makes a covalent bond to Bruton's tyrosine kinase, an important cancer target. Credit: RCSB PDB/Yang H. Ku Enticing atoms to share their electrons—to make a covalent bond, in other ...

Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic ...

The human organism is composed of numerous types of molecules, both simple and complex, and all fundamental processes in a living body occur in water solutions. Therefore, for a drug to work, it must ...

A group of researchers has demonstrated a method that allows scientists to experimentally measure how the chemical bonds of materials are altered when two different materials are linked together. This ...
