Electronic Properties of 2D Van der Waals Heterostructures of Janus Transition Metal Dichalcogenides with WS2 Monolayer for Photovoltaic Devices: A First Principle Study

Tsigie, Getie (Addis Ababa University, 2020-06)

Building two-dimensional (2D) heterostructure emerges novel properties, with promising applications in photovoltaic (PV) cells. By performing density functional theory (DFT) based firstprinciples calculations, electro ...
Center of Materials Engineering (CME) Enhancing the Cracks-Resistant Behavior of Concrete Materials: Combined effects of TiO2 Nanoparticles and Waste Plastics Fiber

Belete, Balta (Addis Ababa University, 2020-06)

Experimental investigation of the combined effects of TiO2 Nanoparticles (TNP) and Waste Plastic Fiber (WPF) for the modifications of concrete materials has been conducted. The TNP partially substituted cement by the wt. ...
Synthesis of Cetyltrimethylammonium chloride Ceramic Membrane Impregnated with TiO Removal of Hexavalent Chromium(VI) Synthesis of Cetyltrimethylammonium chloride Coated Diatomite Impregnated with TiO2 Nanoparticles Diatomite Nanoparticles For the Removal of Hexavalent Chromium(VI)

Daniel, Getachew (Addis Ababa University, 2019-06)

In this study, manufacture of ceramic membranes modified by nanomaterials (Tio2) and CTAC was done. Materials were synthesized by the application of the sol-gel method with respective amounts measured in the molar ratio ...
