The Performance Evaluation of Meso-Tetraphenyl Porphyrin and Azo Dyes as Photosensitizers in Dye-sensitized Solar Cells.

The photovoltaic properties of five different mono-azo function and meso-tetraphenyl porphyrin dyes have been investigated by computational DFT/TDDFT calculations and measurement of the J-V properties of their cells. The photovoltaic efficiency of the cells based on these dyes were determined by both experimental and theoretical methods. The efficiency-to-cost ratios of the azo-dye cells showed that they could be cheaper substitutes to porphyrin-based cells.

Uncovering the inhibitory potentials of leaf and its bioactive compounds against Plasmodium lactate dehydrogenase for malaria therapy.

Malaria control efforts have been hampered due to the emergence of resistant malaria parasite strains and the coinciding events of Covid-19. The quest for more effective and safe treatment alternatives is driving a slew of new studies that must be accelerated if malaria can be overcome. Due to its reported antimalarial activity, we studied the effects of extract and fractions of leaf on Plasmodium lactate dehydrogenase (pLDH) activity using an in vitro assay.
