The synthesis of enantiopure molecules from achiral precursors without the need for pre-existing chirality is a major challenge associated with the origin of life. We here show that an enantiopure ...

Aluminium can be obtained from aluminium ore (Al 2 O 3) by a process called electrolysis. Oxygen is also produced by this reaction. The balanced equation for this process is: \(\mathbf{2}Al_{2}O_{3}\, ...

Researchers in McGill's Department of Physics have developed a new device that can trap and study DNA molecules without touching or damaging them. The device, which uses carefully tuned electric ...

Introduction Did you know that flour can explode? Luckily, this does not happen spontaneously on your kitchen counter, but only if the conditions are right. You need a very fine powder of flour to ...

Polymerase chain reaction, or PCR, tests for COVID-19 are highly accurate. People on social media, however, are circulating lists of germs that they baselessly claim will cause such tests to be ...

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 high ...
