Mass Spectrometry: The Molecular Scale That Weighs Ions
Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of ions to identify and quantify molecules in a sample.
Chemistry and Materials Sciences
35 glossary terms
Chemistry is the study of how matter rearranges itself. Materials science pushes that study one step further: once you know how molecules behave, what can you build from them? The terms in this section cover reactions and their mechanisms, the periodic table's elements and their families, and the modern engineered materials that rely on precise chemical control. You will find fundamentals such as catalytic converters and titration curves alongside more specialized ideas like yttrium applications or X-ray crystallography. These are the concepts that let chemistry move from the lab bench into batteries, pharmaceuticals, and everything in between.
Liquid Crystal Applications: From Flat Screens to Soft Robots
Liquid crystal applications range from the screens in phones and televisions to smart windows, biosensors, and soft robots.
Zymurgy: From Ancient Brewing to Precision Fermentation
Zymurgy is the applied science of fermentation, the study of how microorganisms transform sugars into alcohol, acids, and gases in processes that underpin brewing, winemaking, and food preservation.
Joule-Thomson Effect: Why Most Gases Cool on Expansion
The Joule-Thomson effect is the temperature change when a real gas expands through a valve at constant enthalpy, with no heat exchange.
Murchison Meteorite: 96 Amino Acids From Before the Sun
The Murchison meteorite's organic compounds include 96+ amino acids formed in space, offering direct evidence that life's building blocks exist beyond Earth.
Kinetic Molecular Theory: How Moving Molecules Explain Gases
Kinetic molecular theory explains gas behavior as the result of constant, random molecular motion whose collisions produce pressure and temperature.
Haber-Bosch Process: The Reaction That Feeds Half the World
The Haber-Bosch process produces ammonia from atmospheric nitrogen, sustaining half the global food supply through synthetic fertilizers.
Isotope Geochemistry: How Atomic Fingerprints Decode Earth's History
Isotope geochemistry reads the ratios of atomic isotopes in rocks, water, and air to reconstruct Earth's history and trace environmental processes.
Hydrogen Isotope Fractionation: Climate Clues in Water
Hydrogen isotope fractionation separates hydrogen's isotopes between substances during physical and chemical processes, driven by mass differences.
Isomerism: Why Mirror-Image Molecules Matter
Isomerism describes compounds that share a molecular formula but differ in structure or spatial arrangement, producing distinct chemical and biological properties.
