After decades of instability making them difficult to study, scientists have discovered a way to stabilise nitrogen molecules.

Professor Meera Mehta from the Department of Chemistry at the University of Oxford led the team of chemists to the discovery.

Nitrogen atoms are best known for forming pairs so any previous attempts to link more of them into longer chains usually failed.

This is because the structures turned into nitrogen gas.

Now, the team created a molecule made of four nitrogen atoms connected in a row, along with an extra electron that helps stabilise the structure.

The structure can now remain in a solid form for weeks rather than disintegrating immediately.

In the solid state, the material persists for weeks, allowing the team to characterise its structure and behaviour in detail, something that has not previously been possible for this class of molecule

The team were able to turn these molecules into solid crustal, allowing them to study the chains in detail.

This research could have significant implications.

The shared electrons across this chain help maintain its stability despite nitrogen’s inherent instability.

This breakthrough could usher in a new era of nitrogen-based materials, potentially leading to advanced applications, experts say.

Nitrogen chains store considerable energy and may be used in future applications such as advanced propellants or rocket fuel.

In addition, nitrogen could be a non-toxic energy storage solution with no carbon emissions.

They have been found to be reactive and energy-rich, with the ability to transfer nitrogen atoms to other molecules.

Furthermore, they may act as nitrene radical sources, which could make it easier, cleaner, and more accurate for scientists to build complex molecules.

Overcoming the nitrogen chains’ natural instability, which once made them so challenging to study, has now opened new research possibilities.

Previously, these nitrogen chains have been speculated to exist only in extreme environments, such as lightning strikes or outer space.

As these chains can now be created and examined on a laboratory bench, researchers have more room to broaden their horizons and focus on these compounds’ potential applications.

The breakthrough study, under the leadership of Professor Mehta, has not just challenged decades-old assumptions, but has significantly enhanced our understanding of nitrogen.

Post-Doctoral Research Associate’s, PhD students, and master’s students from the departments of chemistry at the University of Manchester and the University of Oxford were involved in the study.

Antonia Hunt was just a teen when she was left in Brittany in September 1939, as her parents assumed World War II would be similar to the static trench warfare of World War I.

But the advancement of Panzers proved them wrong, leading to Antonia’s capture in a prisoner of war camp near the Alps.

Surviving on luck and charisma, Antonia’s war experiences include daring adventures, Gestapo interrogation, and even romance.

Charlotte Ellis, Antonia’s granddaughter, kindly agreed to a follow up show at Florence Park Community Centre.

The demand for seats had previously outstripped supply, leading Charlotte to agree to another presentation on Tuesday, April 28, at 7.30pm, allowing more people to witness the wartime chronicles of her grandmother.

Antonia’s story is set to be part of celebrations marking notable local happenings as an open day at the Florence Park Community Centre is scheduled for Sunday, April 19.

The day features Frances Moody, a charismatic local historian, who will present an illustrated talk on the history and design of the Florence Park estate at 3pm.

Ms Moody, known for her engaging speaking style and profound knowledge, promises to shed light on the unique architectural designs of the houses on Florence Park Road.

In another upcoming event, the UPP will screen a famous cycling film on Thursday this week in memory of Jonny Ives.

Both Antonia’s story and the other community events underline the rich historic and cultural life of the community. Tickets are available online. 

A total of 26 players, aged between eight and nearly 80, took part in the round-the-clock challenge to raise money for The Hummingbird Centre, which supports people affected by cancer.

The event took place at the centre’s headquarters in Launton, near Bicester, starting at 8pm on Friday, April 10, and finishing at 8pm the following evening.

Ian Critchley, one of the organisers from Fritwell Table Tennis Club, said: “What a brilliant event.

“It even got a bit competitive at times, though the scoring went a bit awry in the middle of the night.

“Overall, it was really good fun and there was a lot of laughter from the beginning to end.”

Paul Harris, a trustee of The Hummingbird Centre, said the event brought people together.

He said: “We had many supporters, friends and family pop in and say hello.

“Some had never heard of the centre before, but came along after hearing about the challenge to take part and show their support.”

The Hummingbird Centre has supported thousands of people since it opened in 2014.

It relies entirely on donations and volunteers to provide its services, which include therapy, counselling, and activities for guests.

Donations are still being accepted.
