In this work, the transfer matrix method (TMM) is employed to investigate optical properties of one-dimensional periodic and quasiperiodic photonic crystals containing nematic liquid crystal (NLC) layers. This structure expressed as (ABC)J(CBA)J made alternated layers isotropic dielectrics SiO2 (A), BGO (B) (C). The simulation study shows that proposed ternary configuration exhibits tunable def...

Defect-rich graphene oxide (dGO) was used as sorbent for organic contaminants of emerging concern in tap water, including drugs and dyes, the performance compared to those lower-defects types. The role holes carbonyl- carboxylic groups on nanosheets surface adsorption mechanism efficiency investigated. dGO showed enhanced capacity toward two fluoroquinolone antibiotics (ofloxacin, OFLOX, ciprof...

Introduction: Acquiring a high quality image has assigned an important concern for obtaining accurate diagnosis in nuclear medicine. Detector and collimator are critical component of Single Photon Emission Computed Tomography (SPECT) imaging system for giving accurate information from exact pattern of radionuclide distribution in the target organ. The images are strongly affect...
