Recently, the team achieved success in developing a transformation and genome editing system for paper mulberry. As a result, genetically modified plants with significantly altered lignin composition were produced. The absorbency performance of porous carbon material derived from the gene-edited paper mulberry surpassed that of unmodified paper mulberry, demonstrating its potential for environmental remediation and pollutant treatment. A study published in Horticulture Research on April 23 initially focused on generating transgenic paper mulberry plants with altered expression of BpF5H. Two transgenic lines (BpF5H_OE1 and BpF5H_OE2) displaying 186- and 158-fold higher F5H expression levels, respectively, along with two biallelic mutation lines (BpF5H_KO1 and BpF5H_KO2), were selected for further analysis. Lignin composition analysis revealed the complete absence of S unit lignin in BpF5H_KO2, indicating a total loss of F5H function. Paper mulberry (Broussonetia papyrifera) is a rapidly growing perennial woody plant belonging to the Moraceae family. It has a rich history of utilization in traditional Chinese medicine, animal feed, and papermaking. Challenges such as the extend...

Recently, researchers have revealed the mechanism of alginate oligosaccharide assimilation by gut microorganisms and its potential role in gut inflammation alleviation. The work was published online in Applied and Environmental Microbiology on April 2 and was selected as spotlight article. The metabolism of dietary fiber by gut microorganisms plays important roles in host physiology and health. Seaweeds, such as Laminaria japonica Aresch and Sargassum fusiforme not only are part of the daily diet of humans living near the sea but ha...

A recent breakthrough stemming from research spearheaded by Professor CUI Guanglei at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) under the auspices of the Chinese Academy of Sciences (CAS) has led to the development of a novel dry-film technique for ultra-thin sulfide solid electrolyte preparation and its integration with thick NCM83 cathodes in all-solid-state batteries through an advanced fusion bonding process. The integration of all-solid-state batteries with sulfide electrolytes is emerging as a promising electrochemical system with potential advances in energy density. The demand for thin sulfides, especially those with high flexibility, superior ioni...

The study, published in Nature Communications on April 12, reveals the extraordinary capabilities of the P-doped NiAl oxide catalyst. It can continuously convert soybean oil to diesel-range hydrocarbons for 500 hours without deactivation, outperforming commercial systems with a higher weight hourly space velocity (WHSV) of 6.0 h-1 compared to the typical range of 0.5~3.0 h-1. Green diesel, a blend of diesel-grade hydrocarbons derived from renewable oils such as vegetable oils and animal fats, offers a promising alternative to traditional petroleum diesel. With a chemical composition similar to petroleum diesel, it inte...

Now, a team led by Prof. Gao Jun and Prof. Huang Qingsong from Sichun University, found that interlayer spacings of laminar covalent organic framework (COF) materials readily serve as perfectly selectivity artificial proton channels. These materials can be easily fabricated in bulk. “Previously, the pores of the COF materials were extensively studied for proton conduction. Yet, the pore size is typically larger than 1 nm, precluding the possibility to realize perfect selectivity against ions or water molecules” says Prof. HUANG Qingsong. Biological proton channels are a special type of ion channels, not only because they conduct a different species, but also because they have a selectivity that is far superior to other ion channels. In fact, their selectivity is considered perfect...
