Radiocarbon Dating

14.11.2012

Background Radio carbon dating is a method for determining the age of organic material by measuring the ratio of the naturally occurring radioisotope carbon-14 and the isotope carbon-12 and/ or carbon-13. Carbon-14 is present in carbon dioxides (CO2). Technology An improved method for radiocarbon dating of organic substances by the precise determination of the ratio 14C/13C and/or the ratio 14C/12C or even the absolute quantity of the 14C isotope. The carbon isotope ratio is measured in a cavity after burning the sample. By means of infrared laser spectroscopy one can measure the intensity of the asymmetric stretching vibrations of the CO2 isotopes. Benefits <ul> <li>Very accurate method </li> <li>Significantly more accurate results than previous method</li> <li>Suitable for forensic cases </li> </ul> IP Rights German Patent DE102009045458 EP, US, AU Application Patent Owner Technische Universität Berlin

Overview of the latest five Focus news of the innovations-report:

In the focus: Soft Matter Offers New Ways to Study How Materials Arrange

A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in physics, mathematics and materials.

The doughnut-shaped droplets, a shape known as toroidal, are formed from two dissimilar liquids using a simple rotating stage and an injection needle. About a millimeter in overall size, the droplets are produced individually, their shapes maintained by a surrounding springy material made of polymers.

Droplets in this toroidal shape made ...

In the focus: Functional films for the displays of the future

Frauhofer FEP will present a novel roll-to-roll manufacturing process for high-barriers and functional films for flexible displays at the SID DisplayWeek 2013 in Vancouver – the International showcase for the Display Industry.

Displays that are flexible and paper thin at the same time?! What might still seem like science fiction will be a major topic at the SID Display Week 2013 that currently takes place in Vancouver in Canada.

High manufacturing cost and a short lifetime are still a major obstacle on ...

In the focus: A New Type of Laser

University of Würzburg physicists have succeeded in creating a new type of laser.

Its operation principle is completely different from conventional devices, which opens up the possibility of a significantly reduced energy input requirement. The researchers report their work in the current issue of Nature.

It also emits light the waves of which are in phase with one another: the polariton laser, developed ...

In the focus: Competition in the Quantum World

Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions.

They are the first scientists that simulated the competition between two rival dynamical processes at a novel type of transition between two quantum mechanical orders. They have published the results of their work in the journal Nature Physics.

“When water boils, its molecules are released as vapor. We call this ...

In the focus: GPS solution provides three-minute tsunami alerts

Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset.

For the devastating Japan 2011 event, the team reveals that the analysis of the GPS data and issue of a detailed tsunami alert would have taken no more than three minutes. The results are published on 17 May in Natural Hazards and Earth System Sciences, an open access journal of ...
