The problem is how to find such an atom - among billions of others. Researchers at the University of Gothenburg, Sweden, have developed a laser technique that, in combination with standard techniques, may be able to do the job.
Hafnium is a common metallic element used in nuclear reactors. However, one of its isotopes is hard to find since it is only made when a supernova explodes. This means that if the isotope, called 182Hf, were discovered on Earth, it would prove that a supernova once exploded near our solar system. This has caused physicists around the world to work hard to find the isotope.One among billions
'Our goal is to develop a method that can be of aid when searching for very unusual isotopes. In many cases the standard methods used are hampered by other, interfering atoms. The technique is still in its infancy, but we have shown that our laser beam can remove 99.99 % of the interfering ions in a beam without destroying the ions we are looking for', says Andersson.Journal reference:

Artificial agent designs quantum experiments
19.01.2018 | Universität Innsbruck
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
