Modern AMS (accelerator mass spectroscopy) methods require tiny amounts, about 50 mg.

AMS technology has allowed us to date very small samples (such as seeds) that were previously undatable.

Researchers set out to create more efficient forms of activated carbon by utilizing the superconducting ...

Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.

Since there are practical limits to the age range of the method, most samples must be younger than 50,000 years and older than 100 years.
