| 1 | Soil Nutrient Variance by Slope Position in a Mollisol Farmland Area of Northeast China显示文摘In order to generate scientifically-based comparative information to improve fertilization efficiency and reduce nutrient loss, 610 samples of 122 soil profiles were collected at the 0–60 cm depth to compare soil nutrient contents including soil organic matter(SOM), total nitrogen(TN), total phosphorus(TP), available phosphorus(AP), and available potassium(AK) among different slope positions in a Mollisol farmland area of Northeast China. The contents of SOM and TN typically decreased with increased soil depth at back and bottom slope. Soil loss and deposition tended to decrease SOM and TN at the 0–20 cm soil depth on both the back slope and the slope bottom. The TP firstly decreased from 0–20 cm to 30–40 cm, and then not constantly increased at the back slope and the bottom slope. Due to the characteristics of soil nutrients and crop absorption, the contents of both AP and AK were typically the highest at the summit, followed by the slope bottom and the back slope in the 0–20 cm layer. Generally, in order to sustain the high soil productivity and protect the environment, attention should be paid to soil conservation on back slope; in addition, additional N and P fertilizer is necessary on the back slope. | ZHANG Shaoliang JIANG Lili LIU Xiaobing ZHANG Xingyi FU Shicong DAI Lin | 2016 | Chinese Geographical Science2016，26，4： | 5 |
| 2 | Biomimetic ultrathin pepsomes for photo-controllable catalysis显示文摘Artificial vesicles for mimicking the unique structures and functions of natural organelles represent a promising scientific object in biomimicry.However,the development of the stimuli-responsive and ultrathin vesicles assembled from sequence-defined biomimetic polymers for controllable applications is still a significant challenge.Herein,we report the self-assembly of azobenzene-based amphiphilic alternating peptoids to generate photo-responsive and ultrathin peptoid vesicle(pepsomes)with an average diameter of∼180 nm.Both cryo-transmission electron microscopy(TEM)and dissipative particle dynamics simulation proved that the vesicular membrane was the ultrathin bilayer structure around∼1.6 nm.The photo-responsive ability of pepsomes was demonstrated by the reversible size changes upon the alternative irradiation with ultraviolet(UV)and visible lights,which was attributable to the photoisomerization virtue of azobenzene moiety.As a proof-of-concept,the photo-controllable catalytic action of gold nanoparticles-decorated pepsomes was evaluated toward the borohydride-mediated reduction from 4-nitrophenol to 4-aminophenol.Photo-controllable reversible and recyclable catalytic activity was effectively modulated using the alternative irradiation with UV and visible lights for five cycles.Our work provides a simple strategy to prepare stimuli-responsive and ultrathin vesicles for potential application on nanocatalysis. | Guiping Peng Haibao Jin Fan Liu Xiaoyan Yang Pengliang Sui Shaoliang Lin | 2022 | Science China Chemistry2022，65，12： | 1 |

| 7 | Cathepsin B S-nitrosylation promotes ADAR1-mediated editing of its own mRNA transcript via an ADD1/MATR3 regulatory axis显示文摘Genetic information is generally transferred from RNA to protein according to the classic“Central Dogma”.Here,we made a striking discovery that post-translational modification of a protein specifically regulates the editing of its own mRNA.We show that S-nitrosylation of cathepsin B(CTSB)exclusively alters the adenosine-to-inosine(A-to-I)editing of its own mRNA.Mechanistically,CTSB S-nitrosylation promotes the dephosphorylation and nuclear translocation of ADD1,leading to the recruitment of MATR3 and ADAR1 to CTSB mRNA.ADAR1-mediated A-to-I RNA editing enables the binding of HuR to CTSB mRNA,resulting in increased CTSB mRNA stability and subsequently higher steady-state levels of CTSB protein.Together,we uncovered a unique feedforward mechanism of protein expression regulation mediated by the ADD1/MATR3/ADAR1 regulatory axis.Our study demonstrates a novel reverse flow of information from the post-translational modification of a protein back to the post-transcriptional regulation of its own mRNA precursor.We coined this process as“Protein-directed EDiting of its Own mRNA by ADAR1(PEDORA)”and suggest that this constitutes an additional layer of protein expression control.“PEDORA”could represent a currently hidden mechanism in eukaryotic gene expression regulation. | Zhe Lin Shuang Zhao Xuesong Li Zian Miao Jiawei Cao Yurong Chen Zhiguang Shi Jia Zhang Dongjin Wang Shaoliang Chen Liansheng Wang Aihua Gu Feng Chen Tao Yang Kangyun Sun Yi Han Liping Xie Hongshan Chen Yong Ji | 2023 | Cell Research2023，33，7： | 0 |
| 8 | Effect of external field on phase behavior of ternary systems involving polypeptide显示文摘The lattice theory regarding ternary systems involving a conformationally variable polypeptide and a randomly coiled polymer presented recently is extended to the case where an external orientational field is present. Chemical potentials of the components in the isotropic and anisotropic phases were obtained. The calculations carried out show that the external field exerts a marked effect on the phase behavior of the ternary systems. The isotropic-anisotropic biphasic gap is predicted to shift to lower polymer concentrations and become narrower when the external field exists. The entrance of the randomly coiled polymers into the anisotropic phase is promoted. Influences of chain conformation of polypeptide, chain length and temperature have been studied in the presence of the external field. The comparison between theory and experimental results was also carried out. | LIN Shaoliang LIN Jiaping CHEN Tao TIAN Xiaohui | 2005 | Science China Chemistry2005，48，2： | 0 |
| 9 | Helical supramolecular nanorods via sequential meticulous tailoring of noncovalent interaction and light irradiation显示文摘Polymers are widely recognized to entail random conformations in good solvent governed by the need for achieving the highest entropy to reach thermodynamic equilibrium.In this context,it remains grand challenging to directly arrange them into ordered conformation as building blocks for further self-assembling into hierarchal structures.Herein,we report a simple yet viable strategy to progressively assemble rationally designed azobenzene-containing alternating copolymer(i.e.,poly(binaphthylspacer-azobenzene-alt-hexaethylene glycol),denoting P(BNPSAzo-alt-EG_(6))_(24))into helical supramolecular nanorods.Specifically,P(BNPSAzo-alt-EG_(6))_(24) chains in good solvent are firstly self-assembled into helical single molecular micelles in good solvent via intramolecular π-π interaction between binaphthyl groups as well as between azobenzene moieties.Subsequently,by simply introducing water into the solution that is allowed to dwell for a certain period of time,single molecular micelles are selfassembled into well-defined vesicles.Finally,these isotropic vesicles could be further transformed into anisotropic helical supramolecular nanorods with enhanced aggregate-induced emission(AIE)capability driven by repeated,light-triggered cistrans isomerization of azobenzene moieties with the retention of π-π interacted binaphthyl groups.This study highlights a facile route to yielding morphology-rich,functional assemblies from a single polymer via judiciously exploiting non-covalent interaction and light of different wavelength as highly effective trigger in a non-invasive manner for potential applications in controlled release and fluorescent labelling. | Zhenghui Liu Yuan Yao Xinfeng Tao Jie Wei Shaoliang Lin | 2022 | Science China Chemistry2022，65，9： | 0 |
| 10 | Regulating the self-assembly of rigid 2D ribbon-like amphiphilic homopolymer via tailoring its holistic conformation显示文摘Amphiphilic rigid backbone polymers are traditionally seemed as one-dimensional(1D)rods and show distinct self-assembly behavior to flexible polymers,but they could hardly adapt morphology-tunable self-assembly by changing their holistic conformation upon external stimuli.In this study,we synthesized a series of amphiphilic homopolymers poly(acetylene azobenzene oligoethylene glycol)(P(AAzo-EGx))containing conjugated polyacetylene mainchain,azobenzene pendants and oligo ethylene glycol tails in each unit.This comb-like amphiphilic polymer could be treated as two-dimensional(2D)nanoribbons with tunable holistic conformation via meticulous tailoring intrastrand repulsion and interchainπ-πinteraction of azobenzene pendants by light,temperature,and solvent swelling.P(AAzo-EG_(2))could self-assemble into large vesicles in ambient,whereas transformed to supramolecular helix bundles(SHBs)at 65℃as well as depicted by dissipative particle dynamics(DPD)simulation,and then turned into grass leaf-like micelles upon sequential ultraviolet(UV)and blue light irradiation.The three assemblies featured different stacking mode of PAAzo skeletons although showed similar aggregate induce emission(AIE)effect.In this holistic macromolecular chain conformation-induced self-assembly and morphology transformation,temperature influenced the stacking of hydrophobic parts mainly by tuning the torsion of PAAzo skeleton.Certain amount of good solvent played a vital role by swelling of hydrophobic PAAzo skeleton,and helping the movement and rearrangement of azobenzene pendants and polyacetylene mainchains like a lubricant.The length and diameter of SHBs could be tuned by changing EGxtails.This work uncovered a facile strategy to tailor the self-assembly of rigid backbone polymers for fabrication of functional nanodevices. | Yumeng Gao Weisheng Feng Yao Sun Yuan Yao Liquan Wang Shaoliang Lin | 2023 | Science China Chemistry2023，66，8： | 0 |
