| 1 | A sustainable integration of removing CO_(2)/NO_(x) and producing biomass with high content of lipid/protein by microalgae显示文摘Due to the boost of CO_(2)/NO_(x)emissions which cause environmental pollution,processes that remove such pollutants from flue gas have attracted increasing attention in recent years.Among these technologies,biological CO_(2)/NO_(x)emission reduction has received more interest.Microalgae,a kind of photosynthetic microorganism,offer great promise to convert CO_(2)/NO_(x)to biomass with high content of lipid and protein,which can be used as feedstock for various products such as biodiesel,health products,feedstuff and biomaterials.In this paper,biological CO_(2)/NO_(x)removing technologies by microalgae,together with the products(such as biofuel and protein)and their economic viability are discussed.Although commercial applications of microalgae for biodiesel and protein products are hampered by the high production cost of biomass,the use of CO_(2)/NO_(x)from flue gas as carbon and nitrogen sources can reduce the cost of biomass production,which makes these technologies more competent for real-life applications.Moreover,it is projected that the increasing in CO_(2)allowances will lead to further reduction in the cost of biomass production,which especially favors related products with lower values such as biodiesel.Furthermore,by combining various process optimization and integration,biorefinery is proposed and considered as the crucial component for the sustainable and economically feasible bulk applications of microalgae biomass. | Junying Zhu Baowen Guo Fengxiang Qie Xu Li Xikang Zhao Junfeng Rong Baoning Zong | 2022 | Journal of Energy Chemistry2022，31，10： | 1 |
| 2 | Extension of Highly Efficient Alcohol-promoted Rearrangement into One-pot Domino Palladium-catalyzed Carbonylation for Sterically Crowded Aromatic Six-membered Imides显示文摘Aromatic six-membered imides suffer the introduction of bulky substituents at the imide positions due to the formation of isoimides and low reactivity,preventing from the investigation of the intrinsic molecular properties.Here,we found a highly efficient alcohol-promoted rearrangement from isonaphthalimide to naphthalimide under acid or basic nonaqueous conditions,which can be regarded as model compounds for aromatic six-membered imides.We proposed two-step nucleophilic substitutions in the isomerization mechanistic pathways that were verified by the separation of a key intermediate.Furthermore,in-situ ^(1)H NMR exhibited the first-order kinetics for the isoimide loss process.Finally,the alcohol-promoted isoimide-imide rearrangement was extended to a palladium-catalyzed one-pot domino carbonylation reaction toward sterically crowded aromatic six-membered imides. | GUO Rong ZHANG Jingmei JIA Xiaohui SHI Chunfeng QIE Fengxiang ZHEN Yonggang | 2023 | Chemical Research in Chinese Universities2023，39，6： | 0 |
| 3 | Copper-promoted domino cyanation/Ullmann coupling toward difunctionalized acenaphthylenes with various optoelectronic properties显示文摘Tremendous progress has been made on aromatic fusion of acenaphthylene towards organic semiconductors.However,scarce studies focus on the functionalization of acenaphthylene without resort to aromatic extension,although vinylene double bond is highly reactive ascribed to the ring strain of the fused cyclopentene.Herein,for the first time we employ copper-promoted domino cyanation/Ullmann coupling to achieve a series of difunctionalized acenaphthylene imides(ANIs)with varied optoelectronic properties.Both Ullmann homocoupling and crosscoupling can be combined with cyanation for difunctionalization of ANIs.The introduction of cyano groups influences oppositely not only the energy levels but also the antiaromaticity of the fivemembered rings in ANIs relative to the dimethylamino substituent due to the electron donating or withdrawing effects.By altering the functional units,the optical and electrical characteristics have been tailored rationally;thus p,n or ambipolar semiconducting properties can be achieved for the ANI derivatives.This article opens up possibilities to the development of organic semiconducting materials based on ANIs without aromatic extension,which is promising for applications in organic electronics. | Yang Wang Yang Hu Junfeng Guo Zongrui Wang Yang Li Fengxiang Qie Chunfeng Shi Lei Zhang Yonggang Zhen | 2023 | Science China Chemistry2023，66，5： | 0 |
