The table will be one element longer
The ubiquitous periodic table will soon have a new addition - the "super-heavy" element 112.

More than a decade after experiments first produced a single atom of the element, a team of German scientists has been credited with its discovery.

The team, led by Sigurd Hofmann at the Centre for Heavy Ion Research, must propose a name for their find, before it can be formally added to the table.

Scientists continue the race to discover more super-heavy elements.

Professor Hofmann began his quest to add to the periodic table in 1976.

The fusion experiments he and his colleagues carried out at the centre have already revealed the existence of elements with atomic numbers 107-111.

These are known as "super-heavy elements" - their numbers represent the number of protons which, together with neutrons, give the atom the vast majority of its mass.

To create element 112, Professor Hofmann's team used a 120m-long particle accelerator to fire a beam of charged zinc atoms (or zinc ions) at lead atoms. Nuclei of the two elements merged, or fused, to form the nucleus of the new element.

Powerful particle accelerators speed up the hunt for "super-heavy elements"
These very large and heavy nuclei are also very unstable. They begin to fall apart or "decay" very soon after being formed - within a few milliseconds, in this case.

This releases energy, which scientists can measure to find out the size of the decaying nucleus.

But such experiments produce very few successful fusions, and scientists need increasingly powerful accelerators to run experiments for longer and find the elusive, unstable elements.

This is why it took such a long time for element 112 to be officially recognised by the International Union of Pure and Applied Chemistry (IUPAC).

Its discovery had to be independently verified, and so far only four atoms have ever been observed.

IUPAC temporarily named the element ununbium, as "ununbi" means "one one two" in Latin; but Professor Hofmann's team now has the task of proposing its official name.

He is currently keeping the shortlist under wraps.

Working together

Teams in Russia, the US and Japan are taking part in what Professor Hofmann described as the "friendly competition" to discover new, heavier elements.

In 2006, Professor Hofmann's competitors at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, claimed the discovery of element 118. It was made by bombarding a californium target with a beam of calcium ions.

"We have confirmed some of these results," Professor Hofmann told BBC News.

But he is now setting his sights higher. "We tried the same experiment to get to element 120. We've not seen it yet, but we believe the element exists and, with a long enough beam time, it could be produced," he said.

"It's certainly a race, and it's nice to be first."

Can't say fairer than that.

The rest of the time I intend spending in my blue overalls lying under my car...

NOW tell me Biology isn't interetsing...!

So please ..... ..... ..... sooner rather than later

Thanks!

The Event is on the 3rd November at 11.30am. Can you please let me know if you will be attending, as you can appreciate it is important that we do not disappoint students by not filling the places allocated.

Venue: Partnership Learning Centre, Good Hope Hospital (see map below directly in front of the Pathology building)

http://birmbsql05/home/atoz.aspx?linkid=2191

Programme: there will be a 30 minute lecture by Dr Rajul Singh, Consultant Histopathologist at 11.30 students will be given a 10 minute slot at each of the 6 stalls which are;

Infection Control

Microbiology

Haematology

Bio Chemistry

Histopathology

Phlebotomy/transfusion awareness

Each group will have a volunteer to guide them around, each student will be given an evaluation form to fill in and hand back at the end of the visit.

Can you please let me know if you will require any car parking for your visit.

I hope you will find the event useful and please contact me if you need any further information. Please email me to reserve your place as there are only 30 places available for this session mona.campbell@heartofengland.nhs.uk . Students are welcome to attend at the 14.00pm session which is open to the public but will be less structured, there will be a lecture at 3.30pm by Dr Singh also.
