Biomarker Raman bands of estradiol, follicle-stimulating, luteinizing, and progesterone hormones in blood
Annah, M. Ondieki; Zephania, Birech; Kenneth, A. Kaduki; Catherine, K. Kaingu; Anne, N. Ndeke; Loyce, Namanya (Vibrational Spectroscopy, 2022-08)Variation of the levels of reproductive hormones outside the normal range indicates health problems that include cancer, infertility, and menstrual difficulties. This work reports on a potentially novel method of screening ... -
Co-sensitization effect of chlorophyll and anthocyanin on optical absorption properties and power conversion efficiency of dye-sensitized solar cells
Mukhokosi, Emma Panzi; Mohammed, Tibenkana; Loyce, Namanya; Botha, Nandipha L.; Maaza, Maliki; Velauthapillai, Dhayalan (Springer, 2024-04)In this article, the chemical structure, optical absorption and photoluminescence properties of un/adsorbed dyes of hibiscus flower (H), pumpkin leaf (P), sweet potato leaf (S) and their composites (H: P & H: S) have been ... -
Optical absorption and photoluminescence properties of Cucurbita maxima dye adsorption on TiO2 nanoparticles
Emma, Panzi Mukhokosi; Maliki, Maaza; Muhammed, Tibenkana; Nandipha, L Botha; Loyce, Namanya; Madiba, I G; Michael, Okullo (IOP Publishing Materials Research Express, 2023-04)Dye-sensitised solar cells (DSSCs) are 3rd generation photovoltaic device that imitate photosynthesis in plants. The fundamental concept of a DSSCs is that the photoanode is covered by the dye as a sensitiser. Natural dyes ...
