Abstract
Traditional vapor compressors for residential and industrial cooling create a vicious cycle: Cooling contributes to global warming, which then demands more cooling. These systems are a major source of greenhouse gas emissions because of their limited efficiency and direct leaks of harmful hydrofluorocarbons from billions of appliances worldwide (1). Solid-state cooling systems are emerging alternatives that provide more sustainable solutions. They use either the thermoelectric effect to convert electric energy to temperature difference or the caloric effect, which allows reversible temperature changes in response to external stimuli. However, existing solid-state cooling systems are limited by the lack of proper materials. On page 56 of this issue, Piper et al. (2) describe a family of organic ionic plastic crystals that exhibit a pressure-driven caloric effect. This potentially large group of materials could provide energy-efficient cooling at low temperatures suitable for residential and industrial applications.
期刊介绍：
Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research.
Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated.
Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
