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).<br><br>
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.
<li>Very accurate method </li>
<li>Significantly more accurate results than previous method</li>
<li>Suitable for forensic cases

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
