“In this work, the properties of Mg(1-x)Zn(x)O thin films are investigated as an example of a protective layer material with a small bandgap in a plasma display panel, to analyze the impact of these kinds of materials on the discharge properties. Using the first principles calculation method, the electronic structure of
Mg(1-x)Zn(x)O crystal is analyzed, and an analytical formula is obtained for the values of the bandgap. A cubic structure is obtained for x between 0 and 0.625. The secondary electron emission coefficients gamma of Neon and Xenon with the Mg(1-x)Zn(x)O films are then evaluated based on Hagstrum’s Bafilomycin A1 cost theory. The gamma value for Xe ions is zero, until a concentration of 0.375 is reached, when the bandgap is about 5.1 eV. At x 0.375 and beyond the condition for Auger emission by xenon ions is fulfilled, and for x>0.375 the gamma value increases continuously until a value of 0.07 is reached for x 0.625. The gamma value for Ne increases from 0.25 to 0.38 when the ZnO proportion is increased from 0 to 0.625. The discharge characteristics of the SM-PDP with Mg(1-x)Zn(x)O protective layer are then calculated using the fluid model. When increasing the x value, the working voltage is strongly reduced, while the discharge efficiency is enhanced by about
60% at 20% Xe for a change in x from 0 to 0.625. We find that this increase is mainly caused by increased electron excitation efficiency. Therefore mixed-oxide materials with a small bandgap like MgO-ZnO buy C59 Wnt in principle enable the use of high xenon content plasma displays, while strongly increasing
the discharge efficiency. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3585825]“
“We have recently reported that steroid avoidance LY2603618 chemical structure or withdrawal (SAW) following renal transplantation results in an increase in acute rejection (AR) rates but does not affect graft or patient survival. Cardiovascular risk factors were significantly reduced. It cannot be assumed that the same risks and benefits apply to nonrenal transplants and we have therefore extended this work to evaluate SAW protocols in nonrenal organ transplantation. A detailed literature search identified nine relevant studies; seven in liver, one in cardiac and one in pancreatic transplant recipients. In liver recipients no difference in AR, graft or patient survival was identified. A significant reduction in the risk of new-onset diabetes was observed with SAW, with trends towards benefits in other cardiovascular risk factors, but meta-analysis was hampered by the small number of studies and significant heterogeneity. Some benefits in cardiovascular risk factors were also identified in the cardiac and pancreatic transplant recipients, but again this evidence is of limited quality.
