Researchers Turn Succulent Plant into Living ‘Bio-Solar Cell’

Shlosberg et al. present a method to simultaneously absorb carbon dioxide while producing an electrical current with minimal engineering requirements. Image credit: Shlosberg et al., doi: 10.1021/acsami.2c15123.
Dec 14, 2022 by News Staff

Harvesting an electrical current from biological photosynthetic systems, such as live cells, is typically achieved by immersion of the system into an electrolyte solution. In new research, scientists at Technion in Israel show that the aqueous solution found in the tissues of succulent plants can be used directly as a natural bio-photo electrochemical cell. Shlosberg et al. present a method to simultaneously absorb carbon dioxide while producing an...

Perseverance’s Navigation Camera (Navcam) observations of the direct dust devil encounter: the Navcam scene (the average background image, top panel) and each dust devil image processed to dust amount (five lower panels), masking out only the truly indeterminate areas (gray); the color scale ranges from optical depth, τ = 0 at the bottom (blue) to τ = 0.12 at the top (yellow), and is linear in between; the areas with low signal-to-noise ratio are masked out, and the images also show non-random noise (banding from instrument electronics during readout); the grid on the scene image (top panel) is 5  degrees in local level azimuth and elevation; the darker gray contours are elevation=0 degrees and azimuth=165 degrees.
