QIBEBT wins first prize of 2023 Qingdao Technology Invention Award

http://qibebt.cas.cn/news/zyxw/202408/t20240815_7273375.html

The prize was provided on August 16 at the Qingdao Science and Technology Innovation Conference.

QIBEBT has focused for many years on the problem of high-performance tire treads which presently rely on imports of solution-polymerized styrene-butadiene rubber.

Wang Qinggang, director of the Catalytic Polymerization and Engineering Research Center of QIBEBT, and his project team have created a new material of iron-based combed styrene-butadiene rubber and invented technologies of green, environmentally friendly, controllable and stable industrial production. The Qingdao Institute of Energy has achieved the first 10,000-ton industrial demonstration of iron-based combed styrene-butadiene rubber in the world, and has completed the manufacturing demonstration and sales of more than 500,000 high-performance tires, achieving the highest level A in the EU new labeling law.

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.

A hydrogen-powered tugboat in Qingdao port

https://j.people.com.cn/n3/2025/0627/c95952-20333735.html

The tugboat was designed and built by Shandong Port Qingdao Port Group Co., Ltd. and is equipped with a hybrid system of “hydrogen fuel cells + liquid-cooled lithium batteries” to achieve zero carbon dioxide emissions. It can sail for more than 12 hours at a speed of 9 knots and has a towing force of 82 tons. With technologies such as fully automatic smart on-shore charging, it has become the country’s largest port tugboat in terms of horsepower and lithium battery capacity.
