We kindly invite you to the next meeting of the Modern Trends in Physics Research seminar to be held on March 3rd at 13:00 (an informal part starts at 12:30). Prof. Wiesław I. Gruszecki (Maria Curie-Sklodowska University, Lublin, Poland ) will speak about Smart photosynthesis: Recycling of excitation energy dissipated as heat.

Abstract:

Virtually all life on our planet is powered by the energy of sunlight captured by photosynthetic organisms that convert this energy into forms that can be directly used to drive biochemical reactions. Despite the high efficiency of capturing light quanta, the energy conversion yield of photosynthesis is relatively low and is only a few percent. One of the reasons for this is the thermal dissipation of the excitation energy to protect the photosynthetic apparatus against photodegradation. It turns out that, depending on the current illumination conditions, plants are able to capture a fraction of the thermal energy and direct it back to the photochemical reaction pathways [1]. This “exciting” phenomenon will be presented and discussed.
