High-rate lithium ion batteries with long cycling lives can provide electricity grid stabilization services in the presence of large fractions of intermittent generators, such as photovoltaics. Engineering for high rate and long cycle life requires an appropriate selection of materials for both electrode and electrolyte and an understanding of how these materials degrade with use. High-rate lithium ion batteries can also facilitate faster charging of electric vehicles and provide higher energy density alternatives to supercapacitors in mass transport applications.

High-rate lithium ion batteries can play a critical role in decarbonizing our energy systems both through their underpinning of the transition to use renewable energy resources, such as photovoltaics, and electrification of transport. Their ability to be rapidly and frequently charged and discharged can enable this energy storage technology to play a key role in stabilizing future low-carbon electricity networks which integrate large fractions of intermittent renewable energy generators. This decarbonizing transition will require lithium ion technology to provide increased power and longer cycle lives at reduced cost. Rate performance and cycle life are ultimately limited by the materials used and the kinetics associated with the charge transfer reactions and ionic and electronic conduction. We review material strategies for electrode materials and electrolytes that can facilitate high rates and long cycle lives and discuss the important issues of cost, resource availability and recycling.

This commentary elaborates on the position taken in the focal article, “Baltimore Is Burning” (Ruggs et al., 2016), that partnerships between industrial–organizational (I-O) psychologists and law enforcement agencies could offer valuable insight and practical tools that help to alleviate long-standing and ongoing conflict between police officers and communities of color. I fully support this stance as well as many of the recommendations proposed within the focal article. I-O psychologists indeed have knowledge and resources that could prove useful for supporting police reform efforts. However, although I-O psychologists have much to contribute to the conversation, a recent review by Hall, Hall, and Perry (2016) draws attention to several ways in which law enforcement as a context and police officers as a population are distinct from many of the workplace environments and civilian employee populations that have informed current I-O knowledge and best practices. As such, our traditional methods may be wrought with unique challenges when implemented in law enforcement contexts. If we fail to give serious consideration to this, the role of I-O psychologists in preventing future fires in Baltimore and throughout the United States may be accompanied by unintended consequences. As I-O psychologists prepare to help law enforcement extinguish the flames between police and communities of color, we must anticipate and prepare to safely combat these dangers so we do not add fuel to the fire or get burned in the process of rendering aid.

This article evaluates the oversight of drugs and medical devices by the U.S. Food and Drug Administration (FDA) using an integration of public policy, law, and bioethics approaches and employing multiple assessment criteria, including economic, social, safety, and technological. Throughout, assessments employing both the multiple criteria and a method of expert elicitation are combined with the existing literature, case law, and regulations providing an integrative historical case study approach. The goal is to provide useful information from multiple disciplines and perspectives to guide discussions regarding appropriate oversight frameworks for nanobiotechnology applications under the FDA’s purview.

The importance of the atmospheric boundary layer for the coupling between the climate and an ice sheet is investigated using a slab model of the atmospheric boundary layer. The model is shown to give reasonable agreement with observations over Antarctica and it is used to look at the effect of different ice-sheet shapes on the boundary layer. The importance of entrainment in bringing heat to the surface is highlighted and is shown to be particularly significant when the ice profile becomes steeper. The model could be used as part of an energy-balance model of snow in order to incorporate the interplay of the boundary layer and ice-sheet shape in the ablation process. The slab model could also be used in a GCM as a parameterization of these sub-grid scale processes which are at present ignored in models on a global scale.
