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.

Buckyball sandwiches combine fullerenes and graphene. But new research shows that commonly accepted radiocarbon dating standards ...

Most radiocarbon dating today is done using an accelerator mass spectrometer, an instrument that directly counts the numbers of carbon-14 and carbon-12 in a sample.

A detailed description of radiocarbon dating is available at the Wikipedia radiocarbon dating web page.

Among the significant events that caused a temporary but significant spike in the atmospheric carbon-14 to carbon-12 ratio were above-ground nuclear test detonations in the two decades following World War II.

is a term for radiocarbon dating based on timestamps left by above-ground nuclear explosions, and it is especially useful for putting an absolute age on organisms that lived through those events.

Carbon materials such as nanotubes, graphene, activated carbon and graphite are in high demand.

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

Because the cosmic ray bombardment is fairly constant, there’s a near-constant level of carbon-14 to carbon-12 ratio in Earth’s atmosphere.

In The Cosmic Story of Carbon-14 Ethan Siegel writes: The only major fluctuation [in carbon-14] we know of occurred when we began detonating nuclear weapons in the open air, back in the mid-20th century.

If you ever wondered why nuclear tests are now performed underground, this is why.

The running of interaction strengths (electric charges, weak and strong nuclear charges) has previously been established for the electromagnetic and strong forces, but not for the weak force.

is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly in each atom.
