Clinical impact of nanophotonic blue-light filtering spectacles based on fullerene C60 and polymethyl methacrylate (PMMA) [PDF]

Vojnosanitetski Pregled, 2021
Background/Aim. Blue light might be harmful to the retina. The nano-material based on fullerene C60 and polymethyl methacrylate (PMMA) transforms the light into harmonized light and absorbs violet, blue, and ultraviolet (UV) wavelength.

Observations of sea ice melt from Operation IceBridge imagery [PDF]

The Cryosphere, 2020
The summer albedo of Arctic sea ice is heavily dependent on the fraction and color of melt ponds that form on the ice surface. This work presents a new dataset of sea ice surface fractions along Operation IceBridge (OIB) flight tracks derived from the ...

Prokaryotic Community Structure and Metabolisms in Shallow Subsurface of Atacama Desert Playas and Alluvial Fans After Heavy Rains: Repairing and Preparing for Next Dry Period

Frontiers in Microbiology, 2019
The Atacama Desert, the oldest and driest desert on Earth, displays significant rains only once per decade. To investigate how microbial communities take advantage of these sporadic wet events, we carried out a geomicrobiological study a few days after a
