  • Ivbanikaro, Anna E.; Okonkwo, Jonathan O.; Sadiku, Emmanuel R.; Maepa, Charity (De Gruyter, 2023-08)
    Water pollution is an issue of global concern that demands effective and sustainable solutions through water purification. Adsorption is a popular method for water treatment because it is inexpensive and has a high performance ...
  • Tibaijuka, J.J.; Nyarige, Justine Sageka; Diale, M.; Mlyuka, N.R.; Samiji, M.E. (Springer, 2023-01)
    This work investigated the effect of thermal treatment of as-deposited chromium (Cr) thin films in a vacuum and argon/oxygen ambient for effective deposition of spectral selective solar absorber multilayer films. The DC ...
