Recently, Prof. Jiawei Zhu and Prof. Heqing Jiang from Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Science, (QIBEBT, CAS) have developed a B-site rock-salt-ordered double perovskite oxide of Sr2CuWO6 with superexchange-stabilized long-distance Cu sites for efficient and stable CO2 electroreduction. Carbon dioxide electroreduction (CO2RR) into high-value chemical feedstocks and fuels is a potential way to realize the carbon-neutral cycle. Cu-oxide-based catalysts are promising for CO2 electroreduction, but suffer from inevitable reduction and...

Recently, scientists from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS) have developed a droplet-based printing platform that can print single-cell droplets in a "one droplet per well" manner onto culture dishes or 96-well plates. This platform enables scalable, cost-effective, and fully automated single-cell phenotype acquisition and screening. With the rapid development of genome synthesis and editing technologies, droplet-based single-cell phenotype screening has become increasingly important. However, precise and high-throughput distribution of target droplets into specific macroscopi...

To address the limitations of low hydrogen mass transfer rates in the hydrogen-methane conversion process, researchers from the QIBEBT developed a biotrickling filter (BTF). The biotrickling filter facilitates microorganisms growth by utilizing packing material with rough internal surface. Additionally, it ensures full contact between the gas and liquid phases, thereby enhancing hydrogen utilization efficiency. Biological hydrogen-methane conversion refers to the production of methane through the action of microorganisms using hydrogen generated by electrolysis of water with residual power and carbon dioxide present in biogas. This approach promises to o...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS) have pioneered a revolutionary rapid growth screening method for cyanobacteria—dubbed "iCyanVS".Utilizing an original Raman-activated cell sorting equipment (RACS-Seq), this method eliminates the need for cell separation (typically taking ~20 days) and cultivation (usually requiring ~5 days). Instead, it successfully identifies and isolates engineered cyanobacterial single cells with robust growth in high-salt environments from a mixed mutant library, a process that involves around 12 hours of 13C-labeling followed by a 10-minute measurement.
Cyanobacteria, as unique photosynthetic prokaryotic organisms, possess the extraordinary ability to directly convert sunlight, seawater, and carbon dioxide into a wide variety of bio-based products.
Currently, the evaluation of cyanobacterial ...

In the race towards developing more “green” ways to sustain a population that runs on carbon-based energy, quick, efficient and large-scale technology and processes are vital. A main method to move away from carbon dependence is water-splitting systems (WWSs) which rely on solar-powered batteries. While it’s a great idea, the process is bogged down with complicated and slow steps, reducing its ability to be appropriately scaled for expansive use. Researchers sought an improved design to increase the speed and stability of the main half reactions needed for WSSs to function at a high caliber: oxygen reduction reactions, oxygen evolution reactions, and hydrogen evolution reactions. As it turns out, the controllable regulation of cobalt (Co) from nanoparticle to single-atom to dual-atom can be a key step forward for the decarbonization of the energy sector.
The rapidly developing field of green energy constantly seeks improvements, and recent advances in dual-atom catalysts hold the potential to revolutionize energy conversion technologies.
In the pursuit of sustainable alternatives to carbon-bas...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have discovered that using the practical polyolefin separator indeed cause the short-circuit of coin cell even at the low current density. They have established a layer-by-layer planar growth model for short-circuit suppression, and proposed the design strategy of 3D magnesiophilic for achieving planar Mg electroplating/stripping behavior. As a promising candidate to current lithium-ion batteries, rechargeable magnesium batteries have attracted extensive attention due to the superior properties of magnesium (Mg) metal anodes, such as high volumetric capacity (3833 mAh/cm3), abundant...
