A new diver-operated microscope is revolutionizing coral research by allowing scientists to observe photosynthesis and ...

Called the Benthic Underwater Microscope Imaging PAM, or BUMP, this microscope is diver-operated and allows scientists to ...

We analyze all-optical switching in chlorophyll-A (Chl-A) molecules for different combinations of pump-probe wavelengths, based on nonlinear intensity-induced excited-state absorption. It is shown ...

Furthermore, to understand the photovoltaic properties of these films, it is essential to analyze the light absorption profile, which determines where excitons are generated, and to investigate the ...

Effect of light availability Ample amounts of light are essential for photosynthesis to occur, as light splits water in the light dependent stage. As the light intensity increases, chlorophyll in ...

When light hits an organic solar cell, it forces the molecules to transfer electrons, which generates an electrical current. The efficiency of the process depends on the arrangement of the molecules ...

For the light-harvesting antenna of PSI, the experimental investigations are hindered by the fact that Lhca1–4 monomers cannot be isolated. Nonetheless, both Lhca1/4 heterodimer (Wientjes and Croce, ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oes.2024.240002 , discusses boosting UV Light Absorption in 2D Semiconductor with quantum dot hybrids for enhanced light emission. Two ...

Steps: Absorption of Light: Chlorophyll and other pigments absorb light energy. Water Splitting: Light energy is used to split water molecules into oxygen, protons, and electrons.

While cyanobacteria contain chlorophyll, other bacteria, for example, purple bacteria and green sulfur bacteria, contain bacteriochlorophyll to absorb light for anoxygenic photosynthesis ...

The effects of light intensity and temperature in S. platensis cultivation with potassium nitrate or urea as nitrogen source were investigated, as well as the biomass chlorophyll contents of this ...
