Perovskite solar cells have developed quickly in the past decade. But like silicon solar cells, the efficiency of perovskite solar cells is highly dependent upon the quality of the perovskite layer, which is related to its crystallinity.
Unfor...

The research team led by Prof. LIANG Han-Pu from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), has synthesized isolated single Fe atoms anchored on N doped carbon (Fe-ISA/NC) using renewable Auricularia auricular-judae (AAJ) as the precursor without the use of any external Fe sources (Figure 1). The development and commercialization of fuel cells relies heavily on Pt-based catalysts which are efficient for the sluggish four-electron oxygen reduction reaction (ORR). However, the high cost, scarcity and poor methanol tolerance of Pt pose a ...

DNA only persists through replication—naturally or synthetically. While humans need genetic material to be reproduced in order to replace old or damaged cells, the ability to replicate DNA in a laboratory setting can give researchers insight into the mechanisms of disease or even the platform to begin developing treatments. Now, a team of researchers based in China has developed a more efficient and cost-effective way to replicate DNA than traditionally used methods. They DNA only persists through replication—naturally or synthetically. While humans need the genetic material to be reproduced in order to replace old or damaged cells, the ability to replicate DNA in a laboratory setting can provide researchers insig...

Fuel, animal feed, other major carbon-rich products could have a sustainable replacement with the help of a new approach to processing a plant biomass material produced naturally by plants during photosynthesis. Called lignocellulose, it comprises half of dry plant matter. Researchers published a review of the work and current status on 24th Feb in Biotechnology Advances. Fuel, animal feed, other major carbon-rich products could have a sustainable replacement with the help of a new approach to processing a plant biomass material produced naturally by plants during photosynthesis.

Recently, a research team led by Prof. ZHAO Guang from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), realized efficient biosynthesis of hypoxanthine in Escherichia coli. Purine compound is significant bioactive substances. It is not only the energy carrier and coenzyme factor, but also the structural component of DNA and RNA. Purine and its derivatives are also widely used in food additives, medicine and other fie...

By systematically analyzing the genetic and biochemical changes of sucrose synthesis in the freshwater cyanobacterium Synechococcus elongatus, an “ion-mediated enzymatic regulation” mechanism for the salt-induced accumulation of compatible solutes was recently revealed by the metabolic engineering group of Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS). Cyanobacteria are a class of the oldest microorganisms on our planet. They are able to perform plant-type oxygenic photosynthesis, converting atmosphere CO2 and light energy to a variety of carbohydrates. Scientists have discovered that many cyano...
