President Trump has repeatedly said he’ll take on toxic chemicals — but many of his administration’s actions are expected to ...

cells release the energy stored in their food molecules through a series of oxidation reactions. Oxidation describes a type of chemical reaction in which electrons are transferred from one ...

Do not attempt to perform this demonstration. The combustion of methane is an example of an exothermic reaction. More energy is released when the bonds in the products are formed than is used to break ...

In contrast, many microorganisms can generate energy by performing chemical reactions that convert compounds to different chemical forms, and release energy in the process. These are known as ...

Chemical engineers develop products and processes that improve the well-being of humanity and touch every aspect of our lives. From discovering new materials and developing new vaccines to solving ...

The opposite is true if we want to make new bonds. Energy is released when new chemical bonds are formed, so bond making is an exothermic process. Breaking or making the same chemical bond will ...

Chemical and biological engineers are uniquely prepared to address these challenges, for example, by developing environmentally friendly, energy-, water- and material-efficient materials and processes ...

Every chemical reaction involves a change in energy because different substances hold different amounts of energy. During the reaction, bonds inside the substances that are reacting together must ...

hybrid sodium-ion battery that charges rapidly and offers impressive energy density. This revolutionary prototype uses sodium ...
