Dose-Dependence of Trap Parameters of OSL Decay from Al_(2)O_(3):C

World Journal of Nuclear Science and Technology 2012年第4期2卷 138-143页

Optically Stimulated Luminescence (OSL) trap parameters can only be reliably determined through the detailed analy- sis of OSL decay curves. In this study the kinetic parameters of a blue-light stimulated luminescence (BLS) decay curve from Al2O3:C sample irradiated at 0.1, 0.15, 0.2, 0.4 and 0.6 Gy beta doses were obtained using the same basic methods with some modifications applied and also by using our suggestion: Active-OSL Approximation (AOSL). The results were compared with those of other studies on the trap parameters of Al2O3:C material.

Bacterial infections and multidrug-resistant bacteria are major health burdens in wound *** antimicrobial agents,e.g.,ε-polylysine(ε-PL),provide a broad spectrum of antibacterial properties and support dermal cell ***,ε-PL was incorporated into polycaprolactone(PCL)/gelatin electrospun scaffolds collected at varying rotation ***,the samples were crosslinked using dopamine hydrochloride to provide highly proliferative dressings with broad antimicrobial *** morphological study showed that the electrospun wound dressings were smooth,continuous,and bead-free,with a mean diameter ranging from 267±7 to 331±8 nm for all random and aligned *** fiber alignment of the electrospun PCL/gelatin scaffolds improved their tensile strength and ***,nanofiber mats are highly hydro-philic,which is crucial for an efficient wound *** samples also demonstrated high antimicrobial properties against common wound bacterial strains,including methicillin-resistant Staphylococcus aureus(MRSA),Staphylococcus aureus(SA),Escherichia coli(EC),Acinetobacter baumannii(AB),and Pseudomonas aeruginosa(PA).Mammalian cell prolifera-tion and morphology assays involving primary human dermal fibroblasts(hDFs)and immortalized keratinocytes(HaCaT)showed excellent biocompatibility of the electrospun mats and remarkably aligned ***,aligned mats showed more cell migration than randomly oriented mats,which is desirable for more efficient wound ***,it can be concluded that aligned PCL/gelatin mats containingε-PL are promising for potential use in wound dressings.
