In order to clarify the role of Dy3+on persistent luminescence properties of MgSiO3:Mn2+, Dy3+and explain the persistent luminescent mechanism, the positron annihilation technique was used to study the defect states of MgSiO3:Mn2+, Dy3+. It was revealed that the structure of deeper traps were not normally respected Mg2+vacancies and oxygen vacancies but the associated defect V"Mg-2Dy•Mg which emerged by Dy3+doping in MgSiO3:Mn2+. This associated defect V"Mg-2Dy•Mg resulted in the excellent persistent luminescence in MgSiO3:Mn2+, Dy3+phosphor and a possible persistent luminescent mechanism for

Abstract:
Inhomogeneous ab initio molecular dynamics simulations show that vaporization of MgSiO3 is incongruent and that the vapor phase is dominated by SiO and O2 molecules. The vapor is strongly depleted in Mg at low temperature and approaches the composition of the liquid near the critical point. We find that the liquid–vapor critical temperature (6,600±150 K) is much lower than assumed in hydrodynamic simulations, pointing to much more extensive supercritical fluid after the Moon-forming impact than previously thought. The structure of the near-critical liquid is very different from what has been s

Another fragment shows doubled cell dimensions when viewed down [30]. The variable occurrence of the satellite reflectioncs and diffuse streaking indicate subtle variations in ordering, chemistry, or both. Images obtained by high-resolution tran

Global studies have demonstrated that using magnesium sulphate (MgSO4) to manage hypertensive disease in pregnancy reduces morbidity and mortality due to severe pre-eclampsia/eclampsia, one of the five direct causes of maternal death.

Although the use of MgSO4 was introduced successfully to the Maternity Unit at Kenyatta National Hospital, Nairobi, in 2001, there has been no systematic introduction
