  • Incentives for aviation biofuel have a limited role in decarbonisation of air travel

    While it was once hoped that biofuel would be a game-changer for transport emissions, evidence has since emerged of unwanted effects from biofuel production, including direct effects such as deforestation to grow biofuel crops, and ‘Indirect Land Use Change’ (ILUC) effects such as the use of previously forested land for agriculture (if agricultural land is used) for biofuel. Recent ...

  • Fluorophenyl LC Phases- what you should know

     They may be called PFP, PFPP, pentafluorophenyl, fluorophenyl or F5 phases. What they all have in common is the structure shown above (the pentafluorophenyl  group) attached to the silica particles. Most modern phases contain a propyl spacer between the above group and the silica, so that the phase looks something like this: ...

  • If carbon pricing is so great, why isn’t it working?

    Political hurdles and low prices have made carbon pricing a low-impact affair. But there’s still hope it can help limit climate change. Earth’s atmosphere has long served as a free dump for carbon dioxide and other greenhouse gases generated by humans. That is changing as policy-makers embrace economists’ advice that the best way to cut greenhouse gas emissions is to charge an ...

  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...

  • Lake water levels for calibration of the S-HYPE model

    Lake water levels are easy to measure, and can be seen as a transformation of discharge. Water level measurements from 42 lakes in Sweden were analysed, and eight of these lakes were modelled using the Swedish S-HYPE model. The objective was to test if a hydrological model can be calibrated using water level data instead of discharge. A semi-analytical lake routing was developed to resolve ...
