Can switching fuels save water? A life cycle quantification of freshwater consumption for Texas coal-and natural gas-fired electricity [PDF]

, 2012
Thermal electricity generation is a major consumer of freshwater for cooling, fuel extraction and air emissions controls, but the life cycle water impacts of different fossil fuel cycles are not well understood.

Conversion of Renewable Lignocellulosic Biomass‐Derived Nanocellulose into Graphene via Pyrolysis and High Shear‐Mediated Exfoliation

Small Structures, EarlyView.
This study uses nanocellulose crystals (NCCs) as the precursor for graphene production. The NCCs are pyrolyzed at 500–800 °C and then converted to graphene in the vortex fluidic device using only water as the solvent. The graphene shows a relatively high quality and TEM confirming <6 layers.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.
