It may be agreed that simply synthesizing a new chemical substance in nano- or macroscopic form is not materials chemistry but just chemical synthesis. For it to be considered materials chemistry, an element of application, function, or design needs to be present. For example, in the case of ...

What is meant by the statement that a pure crystalline organic substance has a sharp melting point? What does the term "racemic mixture" mean? What does the term synthesis mean in chemistry? Is isopropyl alcohol classified as a pure substance (element or compound) or a mixture? Explain. ...
A gradient of electrochemical potential, generally for an ion that may travel across a membrane, is referred to as an electrochemical gradient. The chemiosmosis process is directly related to the synthesis of ATP (which stands for adenosine triphosphate) during cellular respiration by the movement of...
calling the second step a synthesis reaction would be bad as I am already talking about organic chemistry and my resources have been saying it is electrophilic aromatic substitution rather than synthesis. So what is electrophilic aromatic substitution and how does it relate to the chemistry in hair...
Methyl glycinate, the English name is methyl glycinate, is a colorless or light yellow liquid under normal temperature and pressure. Methyl glycinate is an amino acid derivative that can be used as an intermediate in organic synthesis and medicinal chemistry and as a raw material for household pes...
