Acoustical properties of compressed earth blocks: Effect of compaction pressure, water hyacinth ash and lime
Ouma, Justus; Ongwen, Nicholas; Ogam, Erick; Auma, Mercy; Fellah, Z.E.A.; Mageto, Maxwell; Mansour, Mohamed Ben; Oduor, Andrew (Case Studies in Construction Materials, 2023-01-04)This study assessed the potential use of a mixture of lime and water hyacinth ash (WHA) as binders in fabrication of cylindrical compressed earth blocks (CEBs) with good acoustic absorption properties for building and ... -
Thermal properties and pressure-dependent elastic constants of cadmium stannate as a substrate for MEMS: An ab initio study
Ongwen, Nicholas; Ogam, Erick; Fellah, Z.E.A.; Mageto, Maxwell; Othieno, Herrick; Otunga, Henry (Physica B: Condensed Matter, 2023-02-15)Silicon carbide (SiC) has become a suitable replacement to silicon as a substrate for manufacture of microelectromechanical systems (MEMS) that operate in harsh environmental conditions, owing to its better mechanical ... -
