Light Energy Driven Nanocommunications with FRET in Photosynthetic Systems [PDF]
IEEE Access, vol. 9, pp. 44490-44501, 2021, 2020 Chlorophylls and carotenoids, key components of photosynthetic systems, are proposed for molecular communications at the nanoscale with the mechanism of resonance energy transfer. Both types of pigments are introduced focusing on their exceptional properties like energy harvesting, ultra-low energy consumption during transmissions, picoseconds delays ...

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

Effects of tetracycline on growth and antioxidant system of Selenastrum capricornutum
Journal of Hebei University of Science and Technology, 2019 In order to study the toxic effects of tetracycline on algae, Selenastrum capricornutum is selected as the test organism. The growing situation, chlorophyll a contents, superoxide dismutase (SOD) activity, malondialdehyde (MDA) content and reactive ...

Extinction coefficient for red-shifted chlorophylls: Chlorophyll d and chlorophyll f
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2012 Both chlorophyll f and chlorophyll d are red-shifted chlorophylls in oxygenic photosynthetic organisms, which extend photon absorbance into the near infrared region. This expands the range of light that can be used to drive photosynthesis. Quantitative determination of chlorophylls is a crucial step in the investigation of chlorophyll-photosynthetic ...
