There are other ways of measuring a cell's temperature, using glowing proteins or carbon nanotubes, but they often chemically react with the cell and affect its behaviour, making any readouts unreliable.
"What you see in fire is black carbon glowing," she says.
I'd like to hear your ideas, particularly if you have any suggestions for a little device that would give a real-time glowing display of your carbon footprint.
When green products are selected, most respondents select the minimum commitment possible, and this is insensitive to the premium being charged on green power, suggesting that we are largely observing a buy-in 'warm glow' for carbon mitigation.
The ultrathin films on the mica and glow-discharged carbon surfaces were obtained by static dilute solution casting at room temperature.
Samples extracted from sucrose gradients were applied to glow-discharged carbon copper grids and stained with 2% uranyl acetate.
30 µl of sample was deposited for 2 min onto a 200 mesh, glow discharged carbon coated copper grid.
Samples were then spotted onto a glow discharged, carbon coated copper grid (Electron Microscopy Sciences, Hatfield, PA) and incubated for 2 min.
Proteins were applied to glow-discharged carbon coated grids (EM sciences), previously coated with 5 kDa poly-lysine (Sigma-Aldrich, UK) to positively charge the surface.
The peptide hydrogels were then diluted to 100 μM in water immediately before application to a glow-discharged, carbon coated, 400 hexagonal mesh copper grid.
