Progress and Future Perspectives on Li(Na)-CO2 Batteries

Li(Na)-CO2 batteries are attracting significant research attention due to contemporary energy and environmental issues. Li(Na)-CO2 batteries make possible the utilization of CO2 and open up a new avenue for energy conver-sion and storage. Research on this system is currently in its infancy, and its development is still faced with many challenges in terms of high charge potential, weak rate capability, and poor cyclability. Moreover, the reaction mechanism in the battery is still unclear and hard to determine, due to the generation of carbon along with metal carbonates on the cathode. In this review, the authors present the fundamentals and the latest progress related to Li(Na)-CO2 research. Detailed discussions are provided on the electro-chemical reactions on cathode, cathode materials, and electrolytes. Current challenges and future perspectives on Li(Na)-CO2 batteries are also propose

Chemical Identification and Cultural Implications of a Mixed Fermented Beverage from Late Prehistoric China

Humans around the world have shown a remarkable propensity to ferment available sugar sources into alcoholic beverages. These drinks have contributed significantly to cultural innovation and development, including agricultural and horticultural skills to harness natural resources; technologies to produce the beverages and to make special vessels to serve, drink, and present them ceremonially; and their incorporation into feasting and other activities. Molecular archaeological analyses of a range of pottery forms from the site of Liangchengzhen, China, illustrates how contemporaneous chemical data, in conjunction with intensive archaeological and botanical recovery methods, enables the reconstruction of prehistoric beverages and their cultural significance. During the middle Longshan period (ca. 2400-2200 B.C.), a mixed fermented beverage of rice, fruit (probably hawthorn fruit and/or grape), and possibly honey was presented as grave offerings and consumed by the residents of the regional center
