چکیده
A layered silicate, KHSi2O5, was synthesized via a hydrothermal method using an amorphous silicon dioxide (SiO2) block, which is industrial waste. This silicate used as host compound for ion-exchange reactions with Ag+ and Cu2+ ions, the antibacterial properties of ion-exchanged compounds were investigated. The crystal structures retained during reaction; however, in case Cu2+, small amount Cu(OH)2 coexisted. M/Si (where M Ag or Cu) ratios 0.03 - 0.50 0.01 0.32 = Cu, respectively. activity analyzed by inhibition zone two standard model bacteria: Staphylococcus aureus (S. aureus,gram-positive) Escherichia coli (E. coli, gram-negative). Ag-KHSi2O5 Cu-KHSi2O5 samples showed good owing to release ions from their silicates. Here, each sample compared relative calculated based on bacterial area. against S. higher than that E. whereas lower coli.

Properties of Amorphous Silicon Germanium Films and Devices Prepared Using Chemical Annealing
Amorphous silicon germanium solar cells have been extensively used for many years due to the low cost, easy fabrication, tunable bandgap and special properties. However, it is found that the properties of a-SiGe:H materials is not good as a-Si:H, and this limits the application of a-SiGe:H solar cells and brings the stability concern. Recently, it has been shown that this instability is correla...

Introduction: Electronic portal imaging devices (EPIDs) could be used to dose verification of radiotherapy treatment plans. In vivo dose verification is performed to reduce differences found between dose delivered to the patient and the prescribed dose. The aim of this study was to perform a fast and efficient technique for the verification of delivered dose to the patient usin...
