Diamond particles discovered in candle flames

Candle flames contain millions of tiny diamond particles, a university professor has discovered.
Dr Wuzong Zhou, of St Andrews University, found about 1.5 million diamond nanoparticles are created in a candle flame every second it burns.
The diamond particles are burned away in the process.
But the chemistry professor said the discovery could lead to research into how diamonds could be created more cheaply.
Dr Zhou used a new sampling technique to remove particles from the centre of the flame, which is believed to have never been done, and found it contained all four known forms of carbon.
He said: "This was a surprise, because each form is usually created under different conditions.
"This will change the way we view a candle flame forever."
The first candle is said to have been invented in China more than 2,000 years ago.
Previous research has shown hydro-carbon molecules at the bottom of the flame are converted into carbon dioxide by the top of the flame.
But, until now, the process in between has remained a mystery, with the discovery of the diamond nanoparticles, as well as fullerenic particles and graphitic and amorphous carbon.

The BBC news website is a very useful resource when it comes to explaning certain Scientific and environmental phenomenon. Just scroll down through Science/environment articles and you'll find them!
Happy reading and don't burn yourself trying to get those nano diamonds!

Joves i Ciència

Isabel Lammers (see previous post) had also been selected for the prestigious and select program “JOVES I CIÈNCIA” which runs over three years. Her first installment occurred at the start of July over two weeks and this is Isabel telling us what happened and what she did in order to be selected:

The Experience:

Going to Joves i Ciencia has been one of the most incredible experiences in my life. I chose the project on DNA, evolution and biodiversity. This first year we got to work in a laboratory in the Pyrennees using modern techniques like PCR and agarose gel electrophoresis. We also had lessons taught by some brilliant researchers from the CRG (Centre de Regulació Genòmica). We learned how to track genetic diseases, extract and sequence DNA, check for genetically modified food and lots more including how to use cool lab equipment. But it wasn’t all work; we had lots of fun too! We played games at night, went on an excursion, made great friends, explored species of the Pyrenees, watched an exciting film and even had a hilarious scientific comedy show organised for us.

The Selection:

Since there is a long selection process and a low acceptance rate, I never thought I stood much of a chance of getting in. The first part is written and I had to write about my interests, the reason I wanted to go and answer a long question. Later on I got told I had passed onto the second selection process where in an interview lasting half an hour I had to talk about myself, answer some questions and carry out a simple experiment. I thought it went terribly but after an agonizingly long time I was told I’d been accepted. So I highly recommend anyone interested in science to give it a go!

Well done to Isabel and we look forward to seeing how she develops within this program!

If you are a student or parent and are interested in pursuing any of these programs, please feel free to contact the Science Department at r.troy@oakhouseschool.com or a.raig@oakhouseschool.com or leave a comment below.

What is happening in the Science world?

Science students in primary and secondary education may think that science is something that has happened already and everything has been discovered or worked out. But this is so far from the truth...!
Listen to any Science podcast read the news in paper or online and you will see there are many things happening on many fronts.

Who would like to train for a one-way trip to Mars?

How would you deflect an asteroid on a collision course for Earth?

How can we feed 7 billion plus people on the planet and not use up all its resources and cause mass extinction?

These are some of the many issues that today's scientists are tackling and you too could be a part of it!

Watch this space for more news!

Science rocks!
