Pioneering new x-ray facility will study diamonds

Published

on

SCIENTISTS from Aberystwyth University are among the first to have used a pioneering new x-ray facility at one of the world’s most advanced scientific facilities.

The new VERSOX facility at the UK’s national synchrotron radiation facility in Oxfordshire was developed by a team of scientists including Professor Andrew Evans, head of the Department of Physics at Aberystwyth.

Professor Evans chairs the User Working Group of the multi-million pound VERSOX project which delivered its ‘first light’ in June 2017.

Professor Evans and colleagues from the Materials Physics research group at Aberystwyth used the new facility to study diamonds at the beginning of August.

Their work focused on nanodiamonds which measure just five nanometres across. Over a million diamonds would fit on the head of a pin.

The team are studying how these tiny diamonds supplied by diamond producer DeBeers could be used to improve the way drugs are delivered in the body for the treatment of conditions such as cancer.

Five years in its development and construction, VERSOX is part of Diamond Light Source at the Harwell Campus in Oxfordshire.

Designed to work like a giant microscope, Diamond Light Source harnesses the power of electrons to produce bright beams of light that scientists can use to study anything from fossils to jet engines, viruses and vaccines.

VERSOX is one of a series of laboratories known as ‘beamlines’ that capture the bright light beams, giving researchers access to a machine 10,000 times more powerful than a traditional microscope.

Described as a versatile soft X-ray facility, VERSOX has been designed for the study of elements including those essential for life: carbon, nitrogen and oxygen.

Professor Evans said: “VERSOX provides a unique advanced tool for future materials development, as it allows researchers to study the atomic structures, the chemical nature and the composition of surfaces at near-ambient pressure, providing important real-world data for a wide range of materials and applications.

“The facility will be of benefit to a diverse range of scientific areas, including pharmaceuticals, electronics, environmental chemistry and heritage conservation and we are delighted that the Aberystwyth group is one of the first to use it,” he added.

Researchers at Aberystwyth University specialise in the physics of diamond surfaces and coatings with molecules, metals, insulators and graphene and also in the interaction of diamonds with light to pave the way for making new quantum structures.

Aberystwyth is one of eight partner universities to have been awarded a new Centre for Doctoral Training in Diamond Science and Technology (CDT) by the Engineering and Physical Sciences Research Council.

The work of the CDT promises many pioneering diamond-enabled technologies and original scientific insights.
PhD students from the University are using the soft x-ray methods available through VERSOX to probe interfaces between diamond, nanodiamond and organic molecules for applications in electronics, quantum computing and drug delivery.

A world authority on diamond surfaces, Professor Evans is a guest speaker at the week-long European Materials Research Society 2017 Fall Meeting and Exhibition which opens in Warsaw Poland on Sunday (Sept 17).

Penrhyn-coch Brownies compose song

Published

on

PENRHYN-COCH Brownies were congratulated for composing a new Welsh language song recently. The workshops were part of a program of Welsh language workshops organised by Cered – Menter Iaith Ceredigion.

Following a series of workshops with the young singer, Mari Mathias from Talgarreg, the girls decided to compose a song. ‘Yn yr Haf’ was recorded with the girls singing and Mari on the guitar. All the group members received a copy of the song on CD.

Rhodri Francis, Cered’s Development Officer said: “It has been a pleasure to work with the group and we congratulate members on their masterpiece. Thanks also to the leaders for their enthusiasm in securing opportunities for the members to socialise in Welsh outside of school hours.”

Cered’s main aim is to support, influence and develop the use of the Welsh language in Ceredigion through partnership and co-operation, to establish the best possible foundation for the development of the language in the society and community.

Wendy Reynolds, leader of the Brownies unit in Penrhyn-coch said: “The experience has been amazing for the girls and they’ve had a lot of fun doing activities through the medium of Welsh.”

Theatre caravan coming to Aberystwyth

Published

on

THE SMALLEST cinema in a theatre caravan will be on the Promenade in Aberystwyth for three Saturdays this summer.

Staff from Ceredigion Museum, together with the Friends of Ceredigion Museum, will be hosting a series of free entertaining events in and around the theatre caravan on July 28, August 4, and August 11 between 12pm and 4pm.

Sarah Morton, the Events Organiser for Ceredigion Museum said, “We have a series of short local films from the National Film and Screen Archive which links to our summer exhibition relating to the seaside at the museum, in the old Coliseum Theatre. The two minute films show people on the beach and promenade in Aberystwyth as well as Y Borth. We will also have singing from the Showtime Singers to add to the entertainment.

“We will be situated in and near the bandstand and hope to be able to bring some of the traditions of a typical coastal break back to life.”

Besides the theatre caravan, there will be a Guess-the-Object held in the bandstand with museum staff to aid in identifying the mystery objects.

For more details about the caravan and the entertainment, contact Sarah Morton at Ceredigion Museum on 01970 633088

Surprise presentation for retiring cook

Published

AFTER feeding hundreds of children in her role as cook at Ysgol Eglwyswrw for the past 40 years, Mrs Anona Williams is finally hanging up her apron. But there was a shock in store for Mrs Williams when she arrived at the school for one of her last days at work on Tuesday (Jul 17).

Cameras from the S4C magazine programme, Heno, were present to capture her receiving a special award from music conductor and presenter, Alwyn Humphreys.

She started at her post in 1978 and during that time has fed three generations including her own niece and nephew and great-niece and great-nephew.

Headteacher, Edryd Eynon, said Mrs Williams would be sadly missed.

“We will miss her delicious meals and her caring nature,” he said.

“She spoils all the children and is like a grandmother to them. Her contribution to the school is priceless.

“She ran the breakfast and the Cook It clubs and ensured all pupils had an exciting experiences working with food and preparing many delicious recipes.

“Every sports day she would prepare and donate coffee, tea and her famous scones and all the money she raised would be given to school funds. She did this for 40 years.

“Mrs Williams will be sadly missed at Ysgol Eglwyswrw not only for her delicious food – especially her pizza and coleslaw – but also for her caring and loving character. We wish her all the best for the future.”
