Liquid crystal displays (LCDs) are ubiquitous today, and reducing their power consumption offers significant potential for global energy savings. However, lowering power usage often degrades display performance, which users find unacceptable. Among various LCD technologies, fringe-field switching (FFS) liquid crystal devices provide some of the highest image quality available.

Metal–carbon dioxide (CO₂) batteries hold great promise for reducing greenhouse gas emissions and are regarded as one of the most promising energy storage techniques due to their efficiency advantages in CO₂ recovery and conversion. Moreover, rechargeable nonaqueous metal–CO₂ batteries have attracted much attention due to their high theoretical energy density. However, the stability issues of the electrode–electrolyte interfaces of nonaqueous metal–CO₂ (lithium (Li)/sodium (Na)/potassium (K)–CO₂) batteries have been troubling its development, and a large number of related research in the field of electrolytes have conducted in recent years. This review retraces the short but rapid research history of nonaqueous metal–CO₂ batteries with a detailed electrochemical mechanism analysis. Then it focuses on the basic characteristics and design principles of electrolytes, summarizes the latest achievements of various types of electrolytes in a timely manner and deeply analyzes the construction strategies of stable electrode–electrolyte interfaces for metal–CO₂ batteries. Finally, the key issues related to electrolytes and interface engineering are fully discussed and several potential directions for future research are proposed. This review enriches a comprehensive understanding of electrolytes and interface engineering toward the practical applications of next-generation metal–CO₂ batteries.

Professor Matt Rosseinsky OBE FRS, from the University of Liverpool, has been awarded the Royal Medal for the Physical Sciences by the Royal Society for his “pioneering contribution to the design and discovery of materials, changing our understanding of synthesis to create function with digital tools”.

A leading cause of a rising pH value in the world’s oceans is human CO2 emission. As more CO2 is released into the atmosphere and absorbed by the oceans, the water becomes more acidic. This poses problems for many organisms – including sharks, a new study showed. Scientists incubated shark teeth in water with pH levels that reflect the current ocean pH, and in water with a pH value that oceans are predicted to reach by 2300. In the more acidic water of the simulated scenario, shark teeth, including roots and crowns, were significantly more damaged. This shows how global changes reach all the way to the microstructure of sharks’ teeth, the researchers said.

A handheld sensor and innovative technique developed by Texas A&M AgriLife Research scientists could one day offer a noninvasive alternative to food diaries and blood tests when monitoring diet and health.

Using a light-based device, researchers demonstrated that diet, biological age, sex and select nutrient deficiencies could be detected through the skin of live animal models with up to 90% accuracy. The findings, published in Analytical Chemistry, signal a breakthrough in noninvasive health monitoring, including the potential for wearable sensors to provide real-time nutritional and metabolic information.
