A newer option, membrane distillation, reduces the energy inputs by using saltwater heated to lower temperatures flowing on one
side of a membrane while cold freshwater flows on the other.
On the other
side of the
membrane, the glucose is mixed with a fluid and pumped through the microfluidics chip,
while enzymes are added to trigger a reaction.
Positioning herself and her camera on one
side of a semitransparent
membrane, she guided and posed the sitters on the other
side using only her voice; each touch
of a face, a hand, or a selected research - related object against the
membrane is revealed in focus,
while the sitter's gesture or body outline is rendered more softly.
