A novel graphene quantum dot structure takes the cake

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within ...

Biosensor allows real-time oxygen monitoring for 'organs-on-a-chip'

A new biosensor allows researchers to track oxygen levels in real time in "organ-on-a-chip" systems, making it possible to ensure that such systems more closely mimic the function of real organs. This is essential if organs-on-a-chip ...

New tools to characterise physical properties of biofilms

NUS scientists, together with researchers from Nanyang Technological University (NTU) and Imperial College London (ICL), have developed non-invasive biophysical techniques to quantify oxygen concentration and micromechanical ...

Why ozone poses a challenge to food security

Ozone is a well-known and interesting gas. It is thought of as a "good" gas when present in the stratosphere, where it forms the ozone layer sitting 15 to 30 kilometres above Earth that protect life from detrimental ultraviolet ...
