Amperometry at carbon fiber electrodes, a method commonly used to detect molecules released by single living cells, may lead to biased results.

Amperometry Put to Test

Lithium Batteries
Electron holography reveals how lithium ions are distributed during the charge/discharge cycle of a lithium battery.

Biomaterials-Based Organic Electronic Devices
Paper-based circuits demonstrate dramatic improvements in both mechanical flexibility and versatility.

Helium Unraveled
The weakest bound diatomic molecule is He2. All properties of temperature can be modeled if the force between two atoms is known.

Infrared Imaging
Increased signal to noise ratio using InAs quantum dots for photodetection.

Grassland Greenhouse Gases
Grazinglands represent one of the largest land resources in the world but their role as net sinks or sources of greenhouse gases is essentially unknown – until now.

What's Lurking in the Mississippi?
Dioxins in general are shown to be decreasing, those derived from triclosan are increasing in Mississippi sediments.

BASF Plant Grows
BASF expands their methanesulfonic acid (MSA) plant in Ludwigshafen to make them the world's largest MSA supplier.

Speed is the Key
US Department of Energy researchers have quantified the quantum entanglement in photosynthesis.

Too Hot To Handle
Researchers in California have found that multiple layers of graphene retain the heat conducting properties observed in single sheets.
