in recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ils) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. sonic speed is an important thermodynamic property of ionic liquids (ils) and always chosen as a source to determine other properties. a database for the sonic speed of pure ils cre...
Polycyclic Aromatic Hydrocarbons (PAHs) are among of potentially hazardous chemicals for environment and cause health concern. These compounds exhibit carcinogenic and/or mutagenic properties and are listed by the United States Environmental Protection Agency (USEPA) as priority pollutants. Polycyclic Aromatic Hydrocarbons are hardly degraded and therefore bioremediation is often considered as...
The utilization of walnut shell (WS) as partial replacement aggregates and cement is getting more attention in modern research on construction material. Though WS provides lightweight concrete, but less compressive strength porous structure concrete still problematic for its utilization. Thus, this study using untreated powder (UWSP) ultra-fine treated ash (UFTWSA) a substitute cement. Differen...
