| 1 | Production of Free Amino Acid and Short Peptide Fertilizer from Rapeseed Meal Fermentation Using Bacillus flexus NJNPD41 for Promoting Plant Growth显示文摘Free amino acids and short peptides(FAPS)that play an important role in plant nutrition can be extracted from rapeseed meal(RSM)by microbial enzymolysis.The enzymolytic activity of one bacterial strain isolated from RSM for the production of FAPS fertilizer(FAPSF)via solid-state fermentation,as well as its detoxification activity for isothiocyanates and oxazolidinethione,was investigated in this study.The strain NJNPD41 isolated from RSM piled-soil possessed effective proteolytic activity and was identified as Bacillus flexus on the basis of its morphological,physiological,and biochemical properties,as well as 16S rDNA analysis.Compared to the uninoculated control,inoculation with the strain NJNPD41 significantly increased the yield of total free amino acids and short peptides by 115%and decreased the content of isothiocyanates and oxazolidinethione by 53%and 60%,respectively,after solid-state fermentation.The pot and field experiments showed that FAPSF significantly promoted eggplant growth and enhanced the fruit yield and quality of eggplant compared to the control.In conclusion,this study provided a novel method for the high-value utilization of RSM to produce high-quality and low-toxicity FAPSF using the newly isolated strain B.flexus NJNPD41. | LIU Hongjun ZHONG Xi HUANG Yan QIAO Cece SHAO Cheng LI Rong SHEN Qirong | 2018 | Pedosphere2018，28，2： | 5 |
| 2 | Methylation of RAR-β2, RASSF1A, and CDKN2A Genes Induced by Nickel Subsulfide and Nickel-carcinogenesis in Rats显示文摘Objective To investigate the expression variation of RAR‐β2, RASSF1A, and CDKN2A gene in the process of nickel‐induced carcinogenesis. Methods Nickel subsulfide (Ni 3 S 2 ) at dose of 10 mg was given to Wistar rats by intramuscular injection. The mRNA expression of the three genes in induced tumors and their lung metastasis were examined by Real‐time PCR. The methylation status of the 5' region of these genes were detected by Quantitative Real‐time methylation specific PCR. Results The mRNA expressions of the three genes both in muscle and lung tumor were decreased distinctly in comparison with normal tissue. But hypermethylation was found only in muscle tumor. Conclusion These findings suggest that loss of function or decrease of RAR‐β2, RASSF1A, and CDKN2A, as well as the hypermethylation of 5' region of these genes, are related with nickel exposure. | ZHANG Jun ZHANG Jing LI MengJie Wu YouJun FAN YingYing ZHOU Yang TAN LiLi SHAO ZhiHua SHI HongJun | 2011 | Biomedical and Environmental Sciences2011，24，2： | 4 |
| 3 | Controllable broadband multicolour single-mode polarized laser in a dye-assembled homoepitaxial MOF microcrystal显示文摘Multicolour single-mode polarized microlasers with visible to near-infrared output have very important applications in photonic integration and multimodal biochemical sensing/imaging but are very difficult to realize.Here,we demonstrate a single crystal with multiple segments based on the host-guest metal-organic framework ZJU-68 hierarchically hybridized with different dye molecules generating controllable single-mode green,red,and nearinfrared lasing,with the lasing mode mechanism revealed by computational simulation.The segmented and oriented assembly of different dye molecules within the ZJU-68 microcrystal causes it to act as a shortened resonator,enabling us to achieve dynamically controllable multicolour single-mode lasing with a low three-colour-lasing threshold of ~1.72 mJ/cm^(2)(approximately seven times lower than that of state-of-the-art designed heterostructure alloys,as reported by Fan F et al.(Nat.Nanotechnol.10:796-803,2015)considering the single pulse energy density)and degree of polarization>99.9%.Furthermore,the resulting three-colour single-mode lasing possesses the largest wavelength coverage of ~186 nm(ranging from ~534 to ~720 nm)ever reported.These findings may open a new route to the exploitation of multicolour single-mode micro/nanolasers constructed by MOF engineering for photonic and biochemical applications. | Huajun He Yuanjing Cui Hongjun Li Kai Shao Banglin Chen Guodong Qian | 2020 | Light(Science & Applications)2020，9，1： | 2 |

| 7 | Microbial residues as the nexus transforming inorganic carbon to organic carbon in coastal saline soils显示文摘Soil inorganic carbon(SIC),including mainly carbonate,is a key component of terrestrial soil C pool.Autotrophic microorganisms can assimilate carbonate as the main or unique C source,how microorganisms convert SIC to soil organic carbon(SOC)remains unclear.A systematic field survey(n=94)was performed to evaluate the shift in soil C components(i.e.,SIC,SOC,and microbial residues)along a natural salinity gradient(ranging from 0.5‰to 19‰),and further to explore how microbial necromass as an indicator converting SIC into SOC in the Yellow River delta.We observed that SIC levels linearly decreased with increasing salinity,ranging from~12 g kg^(-1)(salinity<6‰)to~10 g kg^(-1)(salinity>6‰).Additionally,the concentrations of SOC and microbial residues exponentially decreased from salinity<6‰ to salinity>6‰,with the decline of 39%and 70%,respectively.Microbial residues and SOC was tightly related to the variations in SIC.The structural equation model showed the causality on explanation of SOC variations with SIC through microbial residues,which can contribute 89% of the variance in SOC storage combined with SIC.Taken together,these two statistical analyses can support that microbial residues can serve as an indicator of SIC transition to SOC.This study highlights the regulation of microbial residues in SIC cycling,enhancing the role of SIC playing in C biogeochemical cycles and enriching organic C reservoirs in coastal saline soils. | Pengshuai Shao Tian Li Kaikai Dong Hongjun Yang Jingkuan Sun | 2022 | Soil Ecology Letters2022，4，4： | 1 |
| 8 | Carrier-free nanoprodrug for p53-mutated tumor therapy via concurrent delivery of zinc-manganese dual ions and ROS显示文摘Human cancers typically express a high level of tumor-promoting mutant p53 protein(Mutp53)with a minimal level of tumor-suppressing wild-type p53 protein(WTp53).In this regard,inducing Mutp53 degradation while activating WTp53 is a viable strategy for precise anti-tumor therapy.Herein,a new carrier-free nanoprodrug(i.e.,Mn-ZnO_(2)nanoparticles)was developed for concurrent delivery of dual Zn-Mn ions and reactive oxygen species(ROS)within tumor to regulate the p53 protein for high anti-tumor efficacy.In response to the mild tumor acidic environment,the released Zn^(2+)and H_(2)O_(2)from Mn-ZnO_(2)NPs induced ubiquitination-mediated proteasomal degradation of Mutp53,while the liberative Mn^(2+)and increased ROS level activated the ATM-p53-Bax pathway to elevate WTp53 level.Both in vitro and in vivo results demonstrated that pH-responsive decomposition of Mn-ZnO2 NPs could effectively elevate the intracellular dual Zn-Mn ions and ROS level and subsequently generate the cytotoxic hydroxyl radical(·OH)through the Fenton-like reaction.With the integration of multiple functions(i.e.,carrier-free ion and ROS delivery,tumor accumulation,p53 protein modulation,toxic·OH generation,and pH-activated MRI contrast)in a single nanosystem,Mn-ZnO_(2)NPs demonstrate its superiority as a promising nanotherapeutics for p53-mutated tumor therapy. | Jinping Wang Chang Qu Xinyue Shao Guoqiang Song Jingyu Sun Donghong Shi Ran Jia Hailong An Hongjun Wang | 2023 | Bioactive Materials2023，，2： | 1 |
| 9 | A New Zircon U-Pb Age of 107.15 Ma for the Dongshan Formation, Boli Basin, Northeast China显示文摘Many studies have focused on the Cretaceous evolution of NE China,including the 973 Scientific Exploration Well Work program,which completed two drill holes in this area.The Cretaceous Basin Group of eastern NE China is highly altered,so the evolution,controlling factors and interpretation of the Early Cretaceous Dasanjiang Basin are controversial,and fundamental aspects of the rocks are poorly understood.The Boli Basin is the largest Cretaceous basin within NE China,but the temporal and spatial extent of Mesozoic strata within this basin,especially the Dongshan Formation,arc not well-known. | ZHANG Sheng FANG Shi SHAO Hongjun WANG Silin ZHAO Yun PING Shuaifei | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 0 |
| 10 | Synergy mechanism of defect engineering in MoS_(2)/FeS_(2)/C heterostructure for high-performance sodium-ion battery显示文摘MoS_(2) is a promising anode material in sodium-ion battery technologies for possessing high theoretical capacity.However,the sluggish Na^(+) diffusion kinetics and low electronic conductivity hinder the promises.Herein,a unique MoS_(2)/FeS_(2)/C heterojunction with abundant defects and hollow structure(MFCHHS)was constructed.The synergy of defect engineering in MoS_(2),FeS_(2),and the carbon layer of MFCHHS with a larger specific surface area provides multiple storage sites of Na^(+)corresponding to the surface-controlled process.The MoS_(2)/FeS_(2)/C heterostructure and rich defects in MoS_(2) and carbon layer lower the Na^(+) diffusion energy barrier.Additionally,the construction of MoS_(2)/FeS_(2) heterojunction promotes electron transfer at the interface,accompanying with excellent conductivity of the carbon layer to facilitate reversible electrochemical reactions.The abundant defects and mismatches at the interface of MoS_(2)/FeS_(2) and MoS_(2)/C heterojunctions could relieve lattice stress and volume change sequentially.As a result,the MFCHHS anode exhibits the high capacity of 613.1 mA h g^(-1)at 0.5 A g^(-1) and 306.1 mA h g^(-1) at 20 A g^(-1).The capacity retention of 85.0%after 1400 cycles at 5.0 A g^(-1) is achieved.The density functional theory(DFT)calculation and in situ transmission electron microscope(TEM),Raman,ex-situ X-ray photon spectroscopy(XPS)studies confirm the low volume change during intercalation/deintercalation process and the efficient Na^(+)storage in the layered structure of MoS_(2) and carbon layer,as well as the defects and heterostructures in MFCHHS.We believe this work could provide an inspiration for constructing heterojunction with abundant defects to foster fast electron and Na^(+) diffusion kinetics,resulting in excellent rate capability and cycling stability. | Linlin Ma Xiaomei Zhou Jun Sun Pan Zhang Baoxiu Hou Shuaihua Zhang Ningzhao Shang Jianjun Song Hongjun Ye Hui Shao Yongfu Tang Xiaoxian Zhao | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 11 | Broadband 1T-polytype tantalum disulfide saturable absorber for solid-state bulk lasers显示文摘1T-polytype tantalum disulfide(1T-TaS_(2)),an emerging strongly correlated material,features a narrow bandgap of 0.2 e V,bridging the gap between zero-bandgap graphene and large-bandgap 2D nonlinear optical(NLO)materials.Combined with its intense light absorption,high carrier concentration,and high mobility,1T-TaS_(2) shows considerable potential for applications in broadband optoelectronic devices.However,its NLO characteristics and related applications have rarely been explored.Here,1T-TaS_(2) nanosheets are prepared by chemical vapor deposition.The ultrafast carrier dynamics in the 400–1100 nm range and broadband NLO performance in the 515–2500 nm range are systematically studied using femtosecond lasers.An obvious saturable absorption phenomenon is observed in the visible to IR range.The nonlinear absorption coefficient is measured to be-22.60±0.52 cm MW-1under 1030 nm,which is larger than that of other typical 2D saturable absorber(SA)materials(graphene,black phosphorus,and MoS_(2))under similar experimental conditions.Based on these findings,using 1T-TaS_(2) as a new SA,passively Q-switched laser operations are successfully performed at 1.06,1.34,and 1.94μm.The results highlight the promise of 1T-TaS_(2) for broadband optical modulators and provide a potential candidate material system for mid-IR nonlinear optical applications. | MENGXIA WANG HAILONG QIU TIANWEN YANG ZHENGPING WANG CHUANRUI ZHAO YUANAN ZHAO TING YU YUYAO JIANG MEILING CHEN YAFEI LIAN GE ZHANG HONGJUN LIU ZHANGGUI HU JIANDA SHAO | 2022 | Photonics Research2022，10，9： | 0 |
| 12 | Shallowing interfacial carrier trap in transition metal dichalcogenide heterostructures with interlayer hybridization显示文摘With the unique properties,layered transition metal dichalcogenide(TMD)and its heterostructures exhibit great potential for applications in electronics.The electrical performance,e.g.,contact barrier and resistance to electrodes,of TMD heterostructure devices can be significantly tailored by employing the functional layers,called interlayer engineering.At the interface between different TMD layers,the dangling-bond states normally exist and act as traps against charge carrier flow.In this study,we propose a technique to suppress such carrier trap that uses enhanced interlayer hybridization to saturate dangling-bond states,as demonstrated in a strongly interlayer-coupled monolayer-bilayer PtSe2 heterostructure.The hybridization between the unsaturated states and the interlayer electronic states of PtSe2 significantly reduces the depth of carrier traps at the interface,as corroborated by our scanning tunnelling spectroscopic measurements and density functional theory calculations.The suppressed interfacial trap demonstrates that interlayer saturation may offer an efficient way to relay the charge flow at the interface of TMD heterostructures.Thus,this technique provides an effective way for optimizing the interface contact,the crucial issue exists in two-dimensional electronic community. | Xu Wu Jingsi Qiao Liwei Liu Yan Shao Zhongliu Liu Linfei Li Zhili Zhu Cong Wang Zhixin Hu Wei Ji Yeliang Wang Hongjun Gao | 2021 | Nano Research2021，14，5： | 0 |
