| 1 | Decarbonizing the Transportation Sector显示文摘FACED with the increasing threat from global warming,the importance of limiting the rise of the global temperatures within 1.5 degrees Celsius has become self-evident.To meet the Paris Agreement objective,by the end of this century,global carbon dioxide emissions are expected to fall to zero.As for China,in September 2020,President Xi Jinping announced the meaningful goal of reaching carbon neutrality by 2060.This not only demonstrates China’s determination to go green,but will also serve as a stimulus for Chinese companies to accelerate technological innovation and industrial upgrading towards a green and sustainable economic development mode. | LIU DAIZONG | 2021 | China Today2021，70，5： | 0 |
| 2 | Epitaxial etching of organic single crystals显示文摘Organic single crystals(OSCs)have received increasing interest in the last decades for their potential applications in flexible electronics.Although there are various subtractive manufacturing methods of organic electronics,the subtractive manufacturing of OSCs is still a challenge,since OSCs are assembled via weak van-der-Waals interactions which are vulnerable and cannot afford damages and suffer the degradation of performances after the process.Here,we develop an epitaxial etching strategy which clips the OSCs and keeps high-quality crystalline nature of the resulting materials.As a result,high-quality organic micro-ribbon arrays are fabricated which maintains 89%charge mobility in average compared with original OSCs,showing great potential of this subtractive manufacturing method in future organic electronics. | Cong Zhang Daizong Ji Lang Jiang Yunqi Liu Dacheng Wei | 2022 | Chinese Chemical Letters2022，33，1： | 0 |
| 3 | Improved synthesis of rupintrivir显示文摘An improved synthesis of rupintrivir (AG7088) was accomplished using three amino acids (L-glutamic acid, D-4-fluorophenylalanine, and L-valine) as the building blocks. The key fragment ketomethylene dipeptide isostere was constructed with the valine derivative and phenylpropionic acid derivative, followed by coupling with a lactam derivative and an isoxazole acid chloride to provide AG7088 totally in eight steps. | LIN DaiZong QIAN WangKe HILGENFELD Rolf JIANG HuaLiang CHEN KaiXian LIU Hong | 2012 | Science China Chemistry2012，55，6： | 0 |
| 4 | The inhibitory effect of transthyretin gene on growth of human hepatoma cells显示文摘Transthyretin(TTR) gene was highly expressed in normal liver and it has been found to be deleted in part of DNA samples from human hepatic cancer. Its mRNA expression was suppressed in most hepatoma samples. In order to study the biological effect of TTR gene on the growth of hepatoma cells, a recombinant vector containing TTR cDNA was constructed by pCMV, then it was transfected into hepatoma cell lines SMMC-7721 and Q3.It has been demonstrated that the inhibition of growth rate of TTR cDNA transfected hepatoma cells was about 50%in strength compared with that of the control. This inhibition was further enhanced when the transfected hepatoma cells were treated with all-trans retinoic acid. Hepatoma cells of cell lines PLC/PRF/5, SMMC-7721 and Q3 as well as hepatoma cells SMMC-7721 transfected with pCMV or pCMV-TTR were analyzed for TTR expression by Northern hybridization. The low level of TTR expression was found in both hepatoma cell lines and in SMMC-7721cells transfected with pCMV alone. However, a remarkable TTR mRNA expression was observed in hepatoma SMMC-7721 cells transfected with pCMV-TTR. It seems possible that TTR gene might be a candidate of cancer suppressor gene for human hepatic cancer. | LIU CHAOTING JIN YAO DAIZONG LI HUIQIU JIANG JIANREN GU.(National Laboratory for Oncogenes and Related Genes,Shanghai Cancer Institute, Shanghai 200032, China.) | 1994 | Cell Research1994，4，1： | 0 |
| 5 | Olefin-linked covalent organic frameworks with twisted tertiary amine knots for enhanced ultraviolet detection显示文摘Though Olefin-linked covalent organic frameworks(oCOFs)possess excellentπ-electron delocalization,the barely reversible olefin linkage brings challenges for oCOFs’synthesis and functionalization.Here,we synthesize new oCOFs with tertiary amine knots which have twisted configuration and electron-donating nature.Investigation into the structural variation and photoelectric performance shows that the twisted configuration of oCOF-TFPA could favor to the intramolecular charge transfer process and reduce the pos-sibility of aggregation-caused quenching.Photoelectrical measurements and electric band structure cal-culation both verify the superiority of this oCOFs’structure in photoelectric sensing. | Qianying Guo Hongyan Ji Lei Yang Daizong Ji Zhaolin Ai Shi Luo Jiatao Sun Yunqi Liu Dacheng Wei | 2022 | Chinese Chemical Letters2022，33，5： | 0 |
| 6 | Noble-metal-free cobalt hydroxide nanosheets for efficient electrocatalytic oxidation显示文摘Cobalt hydroxide has been emerging as a promising catalyst for the electrocatalytic oxidation reactions,including the oxygen evolution reaction(OER)and glucose oxidation reaction(GOR).Herein,we prepared cobalt hydroxide nanoparticles(CoHP)and cobalt hydroxide nanosheets(CoHS)on nickel foam.In the electrocatalytic OER,CoHS shows an overpotential of 306 mV at a current density of 10 mA·cm^-2.This is enhanced as compared with that of CoHP(367 mV at 10 mA·cm^-2).In addition,CoHS also exhibits an improved performance in the electrocatalytic GOR.The improved electrocatalytic performance of CoHS could be due to the higher ability of the two-dimensional nanosheets on CoHS in electron transfer.These results are useful for fabricating efficient catalysts for electrocatalytic oxidation reactions. | Jie Lan Daizong Qi Jie Song Peng Liu Yi Liu Yun-Xiang Pan | 2020 | Frontiers of Chemical Science and Engineering2020，14，6： | 0 |
