Amino acids and peptides may provide biodegradable glasses through a heating-quenching procedure

https://www.science.org/doi/10.1126/sciadv.add8105 https://www.chinadaily.com.cn/a/202303/19/WS6416a55da31057c47ebb5467.html Researchers led by YAN Xuehai from the CAS Institute of Process Engineering have fabricated a family of eco-friendly glasses of biological origin, using biologically-derived amino acids or peptides through heating-quenching, a classic industrial procedure. They chemically modified amino acids and peptides at their ends so they form a super-cooled liquid before decomposition. The glasses exhibited good […]

Peroxisome engineering provides pathway from methanol to fatty alcohols

https://doi.org/10.1073/pnas.2220816120 https://www.cas.cn/syky/202303/t20230316_4880333.shtml Zhou Yongjin and team at the CAS Dalian Institute of Chemical Physics have coupled methanol utilization with fatty alcohol biosynthesis through metabolic pathway compartmentalization in methanolic yeast. Normally, the yield of fatty alcohols synthesized by modified Hansenula polymorpha using methanol as raw material is very low due to the toxicity of methanol and […]

China’s capacity for renewable energies enough to fuel all 27 EU member states

http://j.people.com.cn/n3/2023/0314/c95952-10221971.html According to Song Kailiang, Chairman of the China Energy Construction group, China’s total installed capacity of renewable energy generation in 2022 exceeded that of coal power generation, accounting for 47.3% of the total, and the full-year generation volume exceeded 2.7 trillion kWh, which is equivalent to the annual power consumption of 27 European Union […]

CAS DICP achieves improved photocatalytic production of hydrogen peroxide

https://onlinelibrary.wiley.com/doi/10.1002/adfm.202213173 https://www.cas.cn/syky/202303/t20230314_4880040.shtml Two teams from CAS Dalian Institute of Chemical Physics and the University of Queensland, Australia, have made progress on artificial photosynthesis of hydrogen peroxide (H2O2) by simulating the stomatal structure of plant leaves , resulting in a solar-to-chemical (SCC) conversion rate of 1.23%. The collaborative team grew two-dimensional mesoporous resorcinol-formaldehyde (RF) resin on […]

Integrated biochar solutions can achieve carbon-neutral staple crop production

http://en.people.cn/n3/2023/0221/c90000-10210644.html https://www.nature.com/articles/s43016-023-00694-0 Chinese, United States and Germa scientists have proposed an agricultural carbon reduction solution that could help China achieve carbon neutrality in its food production. According to the research model evaluation, the total carbon emissions from the production of China’s staple crops, including rice, wheat and corn, could have neared 670 teragrams of CO2-equivalent […]

National Engineering Research Center reports progress on satellite-based CO2 emission inventories

The National Engineering Research Center for Remote Sensing Satellite Applications, Institute of Space and Space Information Innovation, Chinese Academy of Sciences, has made progress in the research of remote sensing inversion estimation of carbon dioxide (CO2) emissions from coal-fired power plants. CO2 is mainly generated from fossil fuel combustion, and CO2 emissions from coal-fired power […]
