Stability and ionic mobility in argyrodite-related lithium-ion solid electrolytes.

In the search for fast lithium-ion conducting solids for the development of safe rechargeable all-solid-state batteries with high energy density, thiophosphates and related compounds have been demonstrated to be particularly promising both because of their record ionic conductivities and their typically low charge transfer resistances. In this work we explore a wide range of known and predicted thiophosphates with a particular focus on the cubic argyrodite phase with a robust three-dimensional network of ion migration pathways. Structural and hydrolysis stability are calculated employing density functional method in combination with a generally applicable method of predicting the relevant critical reaction.

Exploring dominant discourses: creating spaces to find voice and cultural identity.

This paper presents the experiences of five women's (of three nationalities and different ethnic backgrounds) challenging dominant cultural discourses and finding their own voice. Starting from a class assignment and individual papers, the five women engaged in a participatory writing project that helped them critically examine dominant discourses of their home countries, the US and other countries, and reflect on how they have been constrained by these dominant discourses and how they have resisted them.

[Comparison of different molecular assays for the rapid detection of enterovirus 71 (EV71)].

Molecular detection of enterovirus (EV)71 RNA based on PCR methods is a quick and sensitive approach. At present, different PCR-based methods for EV71 RNA detection are available, but comparisons of results obtained using different approaches are limited. This study is to compare the analytical sensitivity and specificity of different real-time reverse transcription-polymerase chain reaction (rRT-PCR) and conventional reverse transcription-polymerase chain reaction (cRT-PCR) assays for enterovirus and EV71 detection, Altogether, three rRT-PCR assays and one cRT-PCR assay targeting the 5'UTR gene for universal detection of enterovirus; two rRT-PCR assays andone cRT-PCR assay targeting the VP1 gene for specific detection of EV 71 were examined.
