| 1 | Air-drying changes the distribution of Hedley phosphorus pools in forest soils显示文摘Hedley labile phosphorus(P)pools in soil tend to be several times larger than annual forest requirements,even in highly weathered soils characterized by P limitation.The discrepancy between plant and soil P status could be partly attributable to the frequently adopted air-drying pretreatment that tends to increase soil P solubility.In this study,the effects of air-drying on the distribution of Hedley P fractions were examined using soils collected under 4 forest types at Gongga Mountain,southwestern China.The results showed that the microbial biomass P(Pmic)in the organic horizon decreased markedly after air-drying.The concentrations of Hedley labile P in the air-dried samples were 31%–73%more than those in the field-moist samples.Consequently,the air-drying-induced increments of Hedley labile P pools in the surface soil horizons were 0.8–3.8 times the annual plant P requirements.The organic horizon was more susceptible to the air-drying-induced increases in Hedley labile P than the mineral horizon,probably because of the stronger release of Pmicand disruption of soil organic matter.The quality of P,indexed by the ratio of Hedley labile P to slowly cycling P,shifted in favor of the Hedley labile fractions after air-drying,further revealing that air-drying changed the distribution of Hedley P pools in forest soils.These indicated that the effects of air-drying could not be ignored when interpreting the discrepancy between the P status of plants and the Hedley labile P pools in forest soils.To more efficiently evaluate the P status in forest soils via the Hedley fractionation procedure,the use of field-moist soils is recommended. | Jipeng WANG Yanhong WU Jun ZHOU Haijian BING Hongyang SUN Ji LUO Shengyan PU | 2020 | Pedosphere2020，30，2： | 1 |

| 5 | Compounded chelating agent derived from fruit residue extracts effectively enhances Cd phytoextraction by Sedum alfredii显示文摘Chelating agent is known as the enhancer for metal phytoextraction;however,there is still a lack of efficient and environmentally sustainable chelators.Here,lemon residue extraction(LRE),prepared from 11 kinds of fruit wastes,was combined with N,N-bis(carboxymethyl)glutamic acid(GLDA),and tea saponin(T.S.)for the compounded plant-derived chelator(CPC),and their influences on Cd phytoextraction by the hyperaccumulator Sedum alfredii was evaluated.Among these fruits,the lemon residue extracted the most significant amount of Cd from the soil.The most effective CPC was at the volume ratio of three agents being 15:4:1(LRE:GLDA:T.S.).Compared with the deionized water,the solubility of three Cd minerals was increased by 85–256 times,and Cd speciation was substantially altered after CPC application.In the pot experiment,CPC addition caused evident increases in plant shoot biomass,Cd phytoextraction efficiency,and organic matter content compared with EDTA and nitrilotriacetic acid(NTA)application.CPC induced fewer changes in bacterial community composition compared with EDTA and had no pronounced influence on microbial biomass carbon and bacterialα-diversity,suggesting CPC had a subtle impact on the microbiological environments.Our study provides a theoretical base for the reutilization of fruit wastes and the development of environmental-friendly chelator that assists Cd phytoextraction. | Jipeng Luo Jiabin Liang Yuchao Song Xinyu Guo Youzheng Ning Nanlin Liu Heping Zhao Tingqiang Li | 2021 | Soil Ecology Letters2021，3，3： | 1 |
| 6 | Elevated carbon dioxide stimulates nitrous oxide emission in agricultural soils: A global meta-analysis显示文摘Elevated carbon dioxide (CO_(2))(e CO_(2)) has been shown to affect the nitrous oxide (N_(2)O) emission from terrestrial ecosystems by altering the interaction of plants,soils,and microorganisms.However,the impact of e CO_(2) on the N_(2)O emission from agricultural soils remains poorly understood.This meta-analysis summarizes the effect of e CO_(2) on N_(2)O emission in agricultural ecosystems and soil physiochemical and biological characteristics using 50 publications selected.The e CO_(2) effect values,which equal to the percentage changes of N_(2)O emission under e CO_(2),were calculated based on the natural logarithm of the response ratio to e CO_(2).We found that e CO_(2) significantly increased N_(2)O emission (by 44%),which varied depending on experimental conditions,agricultural practices,and soil properties.In addition,e CO_(2) significantly increased soil water-filled pore space (by 6%),dissolved organic carbon content (by11%),and nitrate nitrogen content (by 13%),but significantly reduced soil p H (by 1%).Moreover,e CO_(2) significantly increased soil microbial biomass carbon(by 28%) and soil microbial biomass nitrogen (by 7%) contents.Additionally,e CO_(2) significantly increased the abundances of ammonia-oxidizing bacteria(AOB) amo A (by 21%),nir K (by 15%),and nir S (by 15%),but did not affect the abundances of ammonia-oxidizing archaea (AOA) amo A and nos Z.Our findings indicate that e CO_(2) substantially stimulates N_(2)O emission in agroecosystems and highlight that optimization of nitrogen management and agronomic options might suppress this stimulation and aid in reducing greenhouse effect. | Yilin DU Xinyu GUO Jinxing LI Yuankun LIU Jipeng LUO Yongchao LIANG Tingqiang LI | 2022 | Pedosphere2022，32，1： | 0 |
| 7 | Thermodynamic insights into n-alkanes phase change materials for thermal energy storage显示文摘n-Alkanes have been widely used as phase change materials(PCMs) for thermal energy storage applications because of their exceptional phase transition performance, high chemical stability, long term cyclic stability and non-toxicity. However, the thermodynamic properties, especially heat capacity, of n-alkanes have rarely been comprehensively investigated in a wide temperature range, which would be insufficient for design and utilization of n-alkanes-based thermal energy storage techniques. In this study, the thermal properties of n-alkanes(C;H;-C;H;), such as thermal stability, thermal conductivity, phase transition temperature and enthalpy were systematically studied by different thermal analysis and calorimetry methods, and compared with previous results. Thermodynamic property of these n-alkanes was studied in a wide temperature range from 1.9 K to 370 K using a combined relaxation(Physical Property Measurement System, PPMS), differential scanning and adiabatic calorimetry method, and the corresponding thermodynamic functions, such as entropy and enthalpy, were calculated based on the heat capacity curve fitting. Most importantly, the heat capacities and related thermodynamic functions of n-heneicosane and n-docosane were reported for the first time in this work, as far as we know. This research work would provide accurate and reliable thermodynamic properties for further study of n-alkanes-based PCMs for thermal energy storage applications. | Huimin Yan Huning Yang Jipeng Luo Nan Yin Zhicheng Tan Quan Shi | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
| 8 | Antibiotic-based small molecular micelles combined with photodynamic therapy for bacterial infections显示文摘The appearance of multidrug-resistant bacteria and the formation of bacterial biofilms have necessitated the development of alternative antimicrobial therapeutics.Antibiotics conjugated with or embedded in nano-drug carriers show a great potential and advantage over free drugs,but the mass proportion of carriers generally exceeds 90%of the nano-drug,resulting in low drug loading and limited therapeutic output.Herein,we fabricated a nanocarrier using antibiotics as the building blocks,minimizing the use of carriermaterials,significantly increasing the drug loading content and treatment effect.Firstly,we conjugated betaine carboxylate with ciprofloxacin(CIP)through an ester bond to form the amphiphilic conjugate(CIP-CB),which self-assembled into micelles(CIP-CBMs)in aqueous solutions,with a CIP loading content as high as 65.4%and pH-induced surface charge reversal properties.Secondly,a model photosensitizer(5,10,15,20-tetraphenylporphyrin(TPP))was encapsulated in CIP-CBMs,generating infection-targeted photodynamic/antibiotic combined nanomedicines(denoted as TPP@CIP-CBMs).Upon accumulation at infection sites or in deep bacterial biofilms,the ester bond between the betaine carboxylate and CIP is cleaved to release free TPP and CIP,leading to a synergetic antibacterial and antibiofilm activity in vitro and in vivo. | Lijiao Yang Shaomin Song Meihui Yin Min Yang Daoping Yan Xiaohui Wan Jipeng Xiao Yuchen Jiang Yongchao Yao Jianbin Luo | 2023 | Asian Journal of Pharmaceutical Sciences2023，18，3： | 0 |
| 9 | Applications of low temperature calorimetry in material research显示文摘Low temperature calorimetry is an experimental method of heat capacity measurements, and heat capacity is one of the most important and fundamental thermodynamic properties of substances. The heat capacity can provide an average evaluation of the thermal property of a sample since it is a bulk property of substances. In the other hand, the condensed states of substances could be mainly controlled by the molecular motions, intermolecular interactions, and interplay among molecular structures. The physical property reflected in a material may be closely related to the energy changes in these three factors, which can be directly observed in a heat capacity curve. Therefore, low temperature calorimetry has been used not only to obtain heat capacity, entropy, enthalpy and Gibbs free energy, but also to investigate and understand lattice vibrations, metals, superconductivity, electronic and nuclear magnetism, dilute magnetic systems and structural transitions. In this review, we have presented the concept of low temperature calorimetry and its applications in the related field of material researches,such as nano-materials, magnetic materials, ferroelectric materials, phase change materials and other materials. | Xin Liu Jipeng Luo Nan Yin Zhi-Cheng Tan Quan Shi | 2018 | Chinese Chemical Letters2018，29，5： | 0 |
