Free press and fair trial: The role of behavioral research.
Suggests that current case law and legal codes concerning media coverage of trials are inconsistent and provide insufficient guidance to judges in their use of restraints and remedies. In addition, it is contended that there currently does not exist adequate empirical research on the impact of news coverage and juror behavior. Legal issues involving free press and fair trial are discussed in relation to research on the nature and extent of news coverage of crime, the potential prejudicial impact of news coverage in actual cases, and simulation studies on the effects of judicial remedies. It is argued that carefully conducted empirical research could provide important information to the courts. Research directions and methodological caveats to increase legal relevance and scientific validity are suggested

Redox flow batteries—Concepts and chemistries for cost-effective energy storage
\ua9 2018 Higher Education Press and Springer-Verlag GmbH Germany, part of Springer Nature Electrochemical energy storage is one of the few options to store the energy from intermittent renewable energy sources like wind and solar. Redox flow batteries (RFBs) are such an energy storage system, which has favorable features over other battery technologies, e.g. solid state batteries, due to their inherent safety and the independent scaling of energy and power content. However, because of their low energy-density, low power-density, and the cost of components such as redox species and membranes, commercialised RFB systems like the all-vanadium chemistry cannot make full use of the inherent advantages over other systems. In principle, there are three pathways to improve RFBs and to make them viable for large scale application: First, to employ electrolytes with higher energy density. This goal can be achieved by increasing the concentration of redox species, employing redox species that store more than one electron or by increasing the cell voltage. Second, to enhance the power output of the battery cells by using high kinetic redox species, increasing the cell voltage, implementing novel cell designs or membranes with lower resistance. The first two means reduce the electrode surface area needed to supply a certain power output, thereby bringing down costs for expensive components such as membranes. Third, to reduce the costs of single or multiple components such as redox species or membranes. To achieve these objectives it is necessary to develop new battery chemistries and cell configurations. In this review, a comparison of promising cell chemistries is focused on, be they all-liquid, slurries or hybrids combining liquid, gas and solid phases. The aim is to elucidate which redox-system is most favorable in terms of energy-density, power-density and capital cost. Besides, the choice of solvent and the selection of an inorganic or organic redox couples with the entailing consequences are discussed
