Sweet smell of success- Impedans in e-nose project

I got a mention in the national press, here in Ireland on Friday. My company worked with Intellisence, a medical sensor company in Belfast on an e-nose project. The basic idea is to sample gas and ionise it in order to measure the light output and characterise the contents. Like smelling the contents.

Plasma whiz kid produces a star in a jar

Another story on fusion. This time a young kid who built a plasma reactor in his garage. I watched the video. Inspiring and over the top at the same time. But, he got to meet the president of the USA. I am sure he has a futue as a scientist and inventor of some note. We do not have many examples for young kids of scientific heros.

Fusion in the cloud

My apologies to the techies who thought this was about the web. No sorry, this is about real science. The paper talks about neutron fluxes from electrical discharges in clouds. I mentioned last week about warm matter. Well in the lightning it seems the plasma is hot enough to produce neutrons.

Plasma threat to modern society

One of the modern threats to our civalisation. A plasma burst from the sun can reach earth with devastatinbg consequences for our modern age. These plasma flares had little  impact on our grand parents because the impact is through electrical phenomenon. The flares create very large electrical currents and induce magnetic fields that reach the earths surface.

Warm matter

In this interesting article for me the authors talk about creating warm matter. This is a plasma really. But most of the universe is in the form of plasma. The authors call it Warm Matter. I had not heard this term before. Warm matter is not some thing we see much on earth. A volcano spews out molten lava at temperatures of several thousand degrees celcius.

Interesting paper on HIPIMS

Interesting paper on HIPIMS plasma instabilities and transport - Arutiun Ehiasarian, Sheffield, http://aip.scitation.org/doi/10.1063/1.3692172 or open access
