Petroleomics: another omics used outside of systems biology

Sep 26, 2013Krisztián Niesz

I assume that you as a faithful reader of this blog are very much aware of the field of genomics. However, I could also risk saying that you don’t have a deep knowledge on the other “omics” outside of the world of biologics. With this post I’m trying to change that. And I do this via introducing petroleomics as a rapidly developing field that was established, on the basis of genomics and proteomics, to revolutionize the petroleum science in much the same way as the previously mentioned two did with medicinal chemistry.

Yet another threat at the door

Sep 15, 2013Krisztián Niesz

What is common between Navin Flourine (an Indian chemical company), the Arctic Ocean and the microbes found near Toolik Lake, Alaska? Well, for one they all produce greenhouse gases, one way or another. While in the latter two cases nature is taking its course, in the first a company from a developing country manufacturing refrigerant HCFC-22 (chlorodifluoromethane, or Freon 22) now has to face the effect of a questionable decision made by humans to stop accepting credits for the synthesis byproduct, HFC-23 (trifluoromethane or Freon 23), which in itself has 14,800 times higher greenhouse gas effect than CO2.[1]

In the worst case scenario, feared by many, the companies in question can refuse to add the extra cost and hassle, even if minimal, accompanying the destruction of HFC-23 into their processes if they don’t get anything in return. This would mean the injection of another 2 billion tons of CO2 equivalent greenhouse gas into the atmosphere by 2020, which is 6%(!) of the global annual CO2 emission. On a side, China has time until 2030 to completely stop producing HCFC-22.

Is Graphene ending the promises for Carbon Nanotubes?

Jun 12, 2013Krisztián Niesz

Let me start with what’s in the background, and why I think this is a valid and potentially a highly influential technological issue these days. This month it rather surprisingly hit the news that three years after Bayer MaterialScience (a leader in material solutions) invested 22 million euros into a carbon nanotube (CNT) production facility which had a very promising future, then they decided to close it down because of lacking groundbreaking applications in sight.1 In other words they trusted, somewhat blindly, that the growth rate of worldwide CNT demand could increase up to the level of the production capacity. Well, as you’d guess this is still very much unbalanced toward the latter. Or, is it the success of the Nobel Prize-winning big brother – graphene – that is shaking the whole CNT empire?
