Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

In contrast to conventional organic synthesis, mechanochemistry does not use solvents that eventually become industrial ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

The substances that are involved in a chemical reaction and that are changed by it are called reactants. The substances that are produced by a chemical reaction are called products. Chemical ...

The atom economy of a chemical reaction is a measure of the percentage of reactants that become useful products. Inefficient, wasteful processes have low atom economies. Efficient processes have ...

Heterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and ...

A new theory predicts one of the effects of macroscopic mechanical forces on mechanochemical organic synthesis by a ball mill. (left) Example of a ...

Nanocatalysts function by providing a platform for reactants to come together more efficiently during chemical reactions. Their nanoscale size allows for a dramatic increase in the surface area ...

Heterogeneous catalysts speed up chemical reactions by being in a different state than the reactants. They are efficient and stable, even under ...

2. Activation of reactants: The precursors require activation to initiate the chemical reaction, which can be achieved through various methods. In thermal CVD, the temperature of the reaction chamber ...

Transition metals have long been used as catalysts to activate small molecules and turn them into valuable products. However, as these metals can be expensive and less abundant, scientists are ...
