Triazine B offers a useful imaging lesson: adding a reactive ingredient can make the complete formulation perform worse.
A holographic recording formulation shows why light-sensitive chemistry often works as a team.
Vitamin C emerged from the centuries-old problem of scurvy and became a landmark achievement in nutrition, structural chemistry, and synthesis.
Only six carbons and two sulfurs - yet a strong sensory signature. Dipropyl disulfide shows why volatile sulfur chemistry dominates many Allium aromas.
Three benzene rings can help make invisible radiation visible: m-terphenyl is an aromatic fluor used in modern scintillator chemistry.
Humans were working with iron oxide chemistry long before chemistry had a name. Some evidence of deliberate ochre processing goes back about 100,000 years.
Before digital photography, making an image appear was only half the job. Another chemical was needed to make it survive the light: sodium thiosulfate.
