A research team from CAS QIBEBT has developed a new homogeneous cathode material, which will enable solid lithium batteries to have higher safety and superior performance, has not yet been named. It achieves over 1,000 times the electronic and ionic conductivity of traditional battery cathode materials. It can smoothly undergo charge and discharge cycles without conductive additives, which simplifies the battery preparation process and also improves the performance of the all-solid-state lithium battery.

Homogeneous cathodes were composed of 100% Li_1.75Ti₂(Ge_0.25P_0.75S_3.8Se_0.2)₃ enable room-temperature all-solid-state lithium batteries to achieve a cycle life of over 20,000 cycles at 2.5 C with a specific capacity retention of 70% and a high energy density of 390 Wh kg⁻¹ at the cell level at 0.1 C. This cathode homogenization strategy contrasts to the conventional cathode heterogeneous design, potentially improving the viability of all-solid-state lithium batteries for commercial applications.

Ocean University of China in Qingdao publishes Blue Book on marine CO2 absorption

https://spc.jst.go.jp/news/250903/topic_2_03.html

A “China Blue Carbon 2025” Blue Book was released in Qingdao. The Blue Book project was led by the Marine Carbon Neutrality Center of the Ocean University of China, and had invited more than 70 experts and scholars from over 30 institutions in China and abroad to conduct joint special research.

The blue paper predicts that carbon dioxide absorption by China’s blue carbon ecosystems has been on the rise for over the past decade, reaching 500 million tons of carbon dioxide equivalent by 2035, at which point China will play a central role in global blue carbon contributions. By 2025, China’s total mangrove area will be approximately 303 square kilometers, with a total carbon storage of 6.03 million tons; seagrass beds will be approximately 265 square kilometers, with a total carbon storage of 2.3 million tons; and coastal salt marshes will be approximately 2,980 square kilometers, with a total carbon storage of 91.55 million tons.

The paper also notes that carbon absorption by shellfish and algae farming in China’s coastal waters has increased over the past 20 years. At the same time, China’s marine energy has also developed, with its offshore wind power capacity now number one in the world and its marine primary and secondary industries achieving “carbon minus” status.

According to the president of Ocean University of China, the university aims to achieve synergistic effects on the ecosystem, society, and economy by developing seagrass bed restoration technology, to building a blue carbon resource survey and calculation system, and even developing technologies to track and treat the sources of coastal pollutants.

A lipid-rich baker’s yeast mutant provides high yields of palmitoleic acid

A team at CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) has developed a lipid-rich mutant strain of Saccharomyces cerevisiae for microbial production of palmitoleic acid— a rare omega-7 fatty acid with proven anti-inflammatory and metabolic benefits.

The team used a combined mutagenesis approach—employing zeocin, an antibiotic-based mutagen, and Atmospheric and Room Temperature Plasma (ARTP)—to create a diverse library of yeast mutants. They then deployed FlowRACS, a Raman flow cytometry system, to select live yeast cells with elevated lipid levels by analyzing their intrinsic single-cell Raman spectra, eliminating the need for chemical stains or genetic reporters.

This method identified the mutant strain MU2R48, which achieved a lipid content of 40.26%—a 30.85% increase over its parental strain SC018—while maintaining similar biomass production.
