Microfluidics & analysis
Organ-on-a-chip models: what they can measure
The question is which function a tissue model reproduces, and how we know.
Chemical principles
Catalysis: changing the reaction pathway
A reaction can reach the same destination by a pathway with a lower energy barrier.
Chemical principles
Understanding pH and hydrogen-ion activity
A one-unit move on the pH scale represents a tenfold change in hydrogen-ion activity.
Materials & energy
How batteries store chemical energy
Follow ions through the electrolyte and electrons through the circuit.
Environmental chemistry
Battery recycling: from spent cells to recovered materials
A collection bin is the beginning of a chemical supply chain, not its final result.
Materials & energy
Polymer structure: how molecular chains shape materials
The same broad idea—many connected units—underlies fibres, films and biological molecules.
Environmental chemistry
Water treatment: separation, capture and destruction
A membrane, a sorbent and a chemical reaction do different jobs.
Environmental chemistry
Green chemistry: evaluating a process from start to finish
Prevention, material efficiency and safer design change the questions we ask about a process.
Molecular life sciences
CRISPR genome editing: targeting, repair and outcome
Targeting a DNA sequence is one part of a much longer chain from molecular tool to useful result.
Molecular life sciences
Lipid nanoparticles: the chemistry of RNA delivery
Lipid nanoparticles show why getting an RNA molecule to the right place is a chemistry problem of its own.
