| 1 | Recent advances in multi-layer composite polymeric membranes for CO_2 separation: A review显示文摘The development of multilayer composite membranes for CO_2 separation has gained increasing attention due to the desire for energy efficient technologies. Multilayer composite membranes have many advantages, including the possibility to optimize membrane materials independently by layers according to their different functions and to reduce the overall transport resistance by using ultrathin selective layers, and less limitations on the material mechanical properties and processability. A comprehensive review is required to capture details of the progresses that have already been achieved in developing multilayer composite membranes with improved CO_2 separation performance in the past 15-20 years.In this review, various composite membrane preparation methods were compared, advances in composite membranes for CO_2/CH_4 separation,CO_2/N_2 and CO_2/H_2 separation were summarized with detailed data, and challenges facing for the CO_2 separation using composite membranes,such as aging, plasticization and long-term stability, were discussed. Finally the perspectives and future research directions for composite membranes were presented. | Zhongde Dai Luca Ansaloni Liyuan Deng | 2016 | Green Energy & Environment2016，1，2： | 6 |
| 2 | CO_2 absorption with ionic liquids at elevated temperatures显示文摘CO_2 capture with ionic liquids(ILs) has attracted many attentions, and most works focused on absorption ability at ambient temperatures, while seldom research was concerned at elevated temperatures.This not only limits the CO_2 absorption application at elevated temperature, but also the determination of the operation condition of the CO_2 desorption generally occurring at higher temperature. This work mainly reported CO_2 solubilities in ILs at elevated temperatures and related properties were also provided. 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide([CnMIm][Tf_2N]) ILs were selected as physical absorbents for CO_2 capture in this work due to their relative higher CO_2 absorption capacities and good thermal stabilities. The long-term stability tests showed that [CnMIm][Tf_2N] is thermally stable at 393.15 K for long time. CO_2 solubilities in [CnMIm][Tf_2N] were systematically determined at temperatures from 353.15 K to 393.15 K. It demonstrated that CO_2 solubility obviously increases with the increase of pressure while slightly decreases with increase of temperature. As the length of alkyl chain on the cation increases, CO_2 solubility in ILs increases. Additionally, the thermodynamic properties including the Gibbs free energy, enthalpy, and entropy of CO_2 were also calculated. | Lu Bai Dawei Shang Mengdie Li Zhongde Dai Liyuan Deng Xiangping Zhang | 2017 | Journal of Energy Chemistry2017，26，5： | 5 |
| 3 | PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO2 separation performance显示文摘CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water and carriers as well as the processability for coating defect-free ultra-thin films. In this study, the blends of hydrophilic polymers polyvinyl pyrrolidone(PVP) and polyvinyl alcohol(PVA) were studied to find an optimal polymer matrix to host carriers in facilitated transport membranes for enhanced CO2 separation. It is found out that the optimized blend is 50/50 PVA/PVP by weight, which shows a significant increase in the water uptake(from 63 to 84%) at equilibrium state compared to the neat PVA. Polyethyleneimine(PEI) was employed to provide sample carriers to evaluate the synergistic effect of PVA and PVP on the CO2 separation performance. A thin film composite(TFC) membrane of the optimized blend(50/50 PVA/PVP with 50 wt% PEI) was fabricated on polysulfone(PSf) porous support. The fabrication of the TFC membranes is simple and low cost, and CO2 permeance of the optimized blend membrane is nearly doubled with the CO2/N2 selectivity remained unchanged, showing great potential for industrial applications of the resulted membranes. | Ragne Marie Lilleby Helberg Zhongde Dai Luca Ansaloni Liyuan Deng | 2020 | Green Energy & Environment2020，5，1： | 5 |

| 5 | Fiber-shaped organic electrochemical transistors for biochemical detections with high sensitivity and stability显示文摘Precise and continuous monitoring of biochemicals by biosensors assists to understand physiological functions for various diagnostics and therapeutic applications.For implanted biosensors,small size and flexibility are essential for minimizing tissue damage and achieving accurate detection.However,the active surface area of sensor decreases as the sensor becomes smaller,which will increase the impedance and decrease the signal to noise ratio,resulting in a poor detection limit.Taking advantages of local amplification effect,organic electrochemical transistors(OECTs)constitute promising candidates for high-sensitive monitoring.However,their detections in deep tissues are rarely reported.Herein,we report a family of implantable,fiber-shaped all-in-one OECTs based on carbon nanotube fibers for versatile biochemical detection including H2O2,glucose,dopamine and glutamate.These fiber-shaped OECTs demonstrated high sensitivity,dynamical stability in physiological environment and antiinterference capability.After implantation in mouse brain,7-day dopamine monitoring in vivo was realized for the first time.These fiber-shaped OECTs could be great additions to the'life science'tool box and represent promising avenue for biomedical monitoring. | Xiaoying Wu Jianyou Feng Jue Deng Zhichang Cui Liyuan Wang Songlin Xie Chuanrui Chen Chengqiang Tang Zhengqi Han Hongbo Yu Xuemei Sun Huisheng Peng | 2020 | Science China Chemistry2020，63，9： | 3 |
| 6 | Modelling of a tubular membrane contactor for pre-combustion CO_2 capture using ionic liquids:Influence of the membrane configuration, absorbent properties and operation parameters显示文摘A membrane contactor using ionic liquids(ILs) as solvent for pre-combustion capture CO_2 at elevated temperature(303-393 K) and pressure(20 bar) has been studied using mathematic model in the present work. A comprehensive two-dimensional(2 D) mass-transfer model was developed based on finite element method. The effects of liquid properties, membrane configurations, as well as operation parameters on the CO_2 removal efficiency were systematically studied. The simulation results show that CO_2 can be effectively removed in this process. In addition, it is found that the liquid phase mass transfer dominated the overall mass transfer. Membranes with high porosity and small thickness could apparently reduce the membrane resistance and thus increase the separation efficiency. On the other hand, the membrane diameter and membrane length have a relatively small influence on separation performance within the operation range. | Zhongde Dai Muhammad Usman Magne Hillestad Liyuan Deng | 2016 | Green Energy & Environment2016，1，3： | 3 |
| 7 | Antimony transformation and mobilization from stibnite by an antimonite oxidizing bacterium Bosea sp. AS-1显示文摘Soils and waters are heavily contaminated by antimony in Xikuangshan(XKS)mine area.It is widely accepted that oxidative dissolution of sulfide minerals and aqueous dissolution are the most prevalent geochemical mechanisms for the release of Sb to the environment.Bosea sp.AS-1 is an antimonite-oxidizer isolated from the mine slag in Xikuangshan Sb mine.Whole genome sequencing revealed the presence of multiple sulfur-oxidizing genes,antimony(Sb)metabolism genes and carbon fixation genes in AS-1 s genome.We therefore hypothesized that under oxic conditions,AS-1 could mediate the oxidation of sulfide and Sb(Ⅲ)in stibnite(Sb_(2)S_(3))and lead to the release of Sb.Indeed,strain AS-1 was discovered as an autotrophic Sb(Ⅲ)-oxidizer.Antimony mobilization studies conducted with strain AS-1showed significantly enhanced mobilization of Sb,and complete oxidation of released Sb and sulfur to Sb(V)and sulfate.In addition,AS-1 induced a faster release of Sb under heterotrophic condition,and new acicular minerals might form.These findings support the hypothesis that microorganisms play an important role in the mobilization and transformation of Sb in XKS mine area and may contribute to our further understanding of the Sb biogeochemical redox cycle in natural environment. | Li Xiang Chaoyang Liu Deng Liu Liyuan Ma Xuan Qiu Hongmei Wang Xiaolu Lu | 2022 | Journal of Environmental Sciences2022，34，1： | 3 |
| 8 | Impact of Background Dynamic and Thermodynamic States on Distinctive Annual Cycle of Near-Equatorial Tropical Cyclogenesis over the Western North Pacific显示文摘In a sharp contrast to tropical cyclone(TC) genesis over the main development region of the western North Pacific(WNP), near-equatorial(0°-5°N) TCs exhibit a distinctive annual cycle, peaking in boreal winter and being inactive in boreal summer. The relative roles of dynamic and thermodynamic background states on near-equatorial TCs formation were investigated based on the observational diagnosis of the genesis potential index(GPI) and high-resolution model simulations. It is found that the background vorticity makes a major contribution to the distinctive annual cycle, while mean temperature and specific humidity fields are not critical. Numerical simulations further indicate that seasonal mean cyclonic vorticity in boreal winter has three effects on TC genesis near the equator. First, the environmental cyclonic vorticity interacts with TC vortex to promote a mid-level outflow, which strengthens boundary layer friction induced ascending motion and thus condensational heating. Second, it produces an equivalent Coriolis effect(via enhanced absolute vorticity), which strengthens positive feedback between primary and secondary circulation. Third, it helps to merge small-scale vortical hot towers(VHTs) into a mesoscale core through vorticity segregation process. However, background vorticity in boreal summer has an opposite effect on TC development near the equator. | Liyuan DENG Tim LI | 2020 | Journal of Meteorological Research2020，34，4： | 1 |
| 9 | Environmental behavior, human health effect, and pollution control of heavy metal(loid)s toward full life cycle processes显示文摘Heavy metal(loid)s(HMs)have caused serious environmental pollution and health risks.Although the past few years have witnessed the achievements of studies on environmental behavior of HMs,the related toxicity mechanisms,and pollution control,their relationship remains a mystery.Researchers generally focused on one topic independently without comprehensive considerations due to the knowledge gap between environmental science and human health.Indeed,the full life cycle control of HMs is crucial and should be reconsidered with the combination of the occurrence,transport,and fate of HMs in the environment.Therefore,we started by reviewing the environmental behaviors of HMs which are affected by a variety of natural factors as well as their physicochemical properties.Furthermore,the related toxicity mechanisms were discussed according to exposure route,toxicity mechanism,and adverse consequences.In addition,the current state-of-the-art of available technologies for pollution control of HMs wastewater and solid wastes were summarized.Finally,based on the research trend,we proposed that advanced in-operando characterizations will help us better understand the fundamental reaction mechanisms,and big data analysis approaches will aid in establishing the prediction model for risk management. | Haoyu Deng Yuling Tu Han Wang Ziyi Wang Yanyu Li Liyuan Chai Wenchao Zhang Zhang Lin | 2022 | Eco-Environment & Health2022，1，4： | 1 |
| 10 | Pebax/TSIL blend thin film composite membranes for CO_2 separation显示文摘In this study a thin film composite(TFC) membrane with a Pebax/Task-specific ionic liquid(TSIL) blend selective layer was prepared. Defect-free Pebax/TSIL layers were coated successfully on a polysulfone ultrafiltration porous support with a polydimethylsiloxane(PDMS) gutter layer. Different parameters in the membrane preparation(e.g. concentration, coating time) were investigated and optimized. The morphology of the membranes was studied by scanning electron microscopy(SEM), while the thermal properties and chemical structures of the membrane materials were investigated by thermo-gravimetric analyzer(TGA), differential scanning calorimetry(DSC) and Fourier transform infrared spectroscopy(FTIR). The CO_2 separation performance of the membrane was evaluated using a mixed gas permeation test. Experimental results show that the incorporation of TSIL into the Pebax matrix can significantly increase both CO_2 permeance and CO_2/N_2 selectivity. With the presence of water vapor, the membrane exhibits the best CO_2/N_2 selectivity at a relative humidity of around 75%, where a CO_2 permeance of around 500 GPU and a CO_2/N_2 selectivity of 46 were documented. A further increase in the relative humidity resulted in higher CO_2 permeance but decreased CO_2/N_2 selectivity. Experiments also show that CO_2 permeance decreases with a CO_2 partial pressure increase, which is considered a characteristic in facilitated transport membranes. | Zhongde Dai Lu Bai Karoline Navik Hval Xiangping Zhang Suojiang Zhang Liyuan Deng | 2016 | Science China Chemistry2016，59，5： | 1 |

| 15 | Self-assembled interlayer aiming at the stability of NiOx based perovskite solar cells显示文摘Inorganic NiO_(x) based inverted structure perovskite solar cells (PSCs) is reported to be more stable than that with the organic hole transport materials.In this work,NiO_(x)/MAPbI_(3) interface chemical reaction induced instability of perovskite is unveiled:Ni^(3+) and I^(-) exhibit redox reactions and deprotonation of MA^(+) happens,which result in interface defects and perovskite lattice deformation.Thus the defective interface accelerates the degradation of perovskite by defect pathways from the bottom interface to the perovskite surface contacting H_(2)O/O_(2).Self-assembled interlayer of NH_(2)^(-)end silane on NiO_(x)separates the reactive NiO_(x)and MAPbI_(3),tunes the interface energy states by–NH_(2) end group.As a result,the PSC based on the silane treated NiO_(x)achieves enhanced PCE of 20.1%with decent stability under environmental and extreme conditions (high temperature,high humidity,light infiltration).Our work highlights the interface chemical problem induced PSC instability and a simple interface modification to achieve the stable PSCs. | Tonghui Guo Zhi Fang Zequn Zhang Zhiqiang Deng Rui Zhao Jing Zhang Minghui Shang Xiaohui Liu Ziyang Hu Yuejin Zhu Liyuan Han | 2022 | Journal of Energy Chemistry2022，31，6： | 0 |
| 16 | Nanocomposite membranes with high-charge and size-screened phosphorylated nanocellulose fibrils for CO_(2)separation显示文摘In this study,cellulose nanofibrils(CNF)of high charge(H-P-CNF)and screened size(H-P-CNF-S)were fabricated by increasing the charge of phosphorylated cellulose nanofibrils(P-CNFs)during the pre-treatment step of CNF production.Results show that the H-P-CNF have a significantly higher charge(3.41 mmol g^(-1))compared with P-CNF(1.86 mmol g^(-1)).Centrifugation of H-P-CNF gave a supernatant with higher charge(5.4 mmol g^(-1))and a reduced size(H-P-CNF-S).These tailored nanocelluloses were added to polyvinyl alcohol(PVA)solutions and the suspensions were successfully coated on porous polysulfone(PSf)supports to produce thin-film nanocomposite membranes.The humid mixed gas permeation tests show that CO_(2)permeability increases for membranes with the addition of H-P-CNF-S by 52%and 160%,compared with the P-CNF/PVA membrane and neat PVA membrane,respectively. | Ragne Marie Lilleby Helberg Jonathan Ø.Torstensen Zhongde Dai Saravanan Janakiram Gary Chinga-Carrasco Øyvind W.Gregersen Kristin Syverud Liyuan Deng | 2021 | Green Energy & Environment2021，6，4： | 0 |
| 17 | Prediction of CO_(2) solubility in deep eutectic solvents using random forest model based on COSMO-RS-derived descriptors显示文摘This work presents the development of molecular-based mathematical model for the prediction of CO_(2) solubility in deep eutectic solvents(DESs).First,a comprehensive database containing 1011 CO_(2) solubility data in various DESs at different temperatures and pressures is established,and the COSMO-RS-derived descriptors of involved hydrogen bond acceptors and hydrogen bond donors of DESs are calculated.Afterwards,the efficiency of the input variables,i.e.,temperature,pressure,COSMO-RS-derived descriptors of HBA and HBD as well as their molar ratio,is explored by a qualitative analysis of CO_(2) solubility in DESs using a simple multiple linear regression model.A machine learning method namely random forest is then employed to develop more accurate nonlinear quantitative structure-property relationship(QSPR)model.Combining the QSPR validation and comparisons with literature-reported models(i.e.,COSMO-RS model,traditional thermodynamic models and equations of state methods),the developed QSPR model with COSMO-RS-derived parameters as molecular descriptors is suggested to be able to give reliable predictions of CO_(2) solubility in DESs and could be used as a useful tool in selecting DESs for CO_(2) capture processes. | Jingwen Wang Zhen Song Lifang Chen Tao Xu Liyuan Deng Zhiwen Qi | 2021 | Green Chemical Engineering2021，2，4： | 0 |
| 18 | Enabling high-efficiency ethanol oxidation on NiFe-LDH via deprotonation promotion and absorption inhibition显示文摘Nucleophile oxidation reaction(NOR), represented by ethanol oxidation reaction(EOR), is a promising pathway to replace oxygen evolution reaction(OER). EOR can effectively reduce the driving voltage of hydrogen production in direct water splitting. In this work, large current and high efficiency of EOR on a Ni, Fe layered double hydroxide(NiFe-LDH) catalyst were simultaneously achieved by a facile fluorination strategy. F in NiFe-LDH can reduce the activation energy of the dehydrogenation reaction, thus promoting the deprotonation process of NiFe-LDH to achieve a lower EOR onset potential. It also weakens the absorption of OH-and nucleophile electrooxidation products on the surface of NiFe-LDH at a higher potential, achieving a high current density and EOR selectivity, according to density functional theory calculations. Based on our experiment results, the optimized fluorinated NiFe-LDH catalyst achieves a low potential of 1.386 V to deliver a 10 mA cm^(-2)EOR. Moreover, the Faraday efficiency is greater than 95%, with a current density ranging from 10 to 250 mA cm^(-2). This work provides a promising pathway for an efficient and cost-effective NOR catalyst design for economic hydrogen production. | Jiawei Shi Huawei He Yinghua Guo Feng Ji Jing Li Yi Zhang Chengwei Deng Liyuan Fan Weiwei Cai | 2023 | Journal of Energy Chemistry2023，，10： | 0 |
| 19 | Investigation on the short-term outcome and prognostic impact of predisposition,and precipitants in inpatients with chronic liver disease from Chinese AcuTe on CHronic LIver FailurE(CATCH-LIFE)cohorts显示文摘Aim:The study aimed to investigate the short-term outcomes of hospitalized patients with chronic liver disease(CLDs)and assess the prognostic impact of predisposition and precipitants,which currently remains unclear.Methods:The study included 3970 hospitalized patients with CLDs from two prospective longitudinal multicenter studies(NCT02457637 and NCT03641872)conducted in highly endemic hepatitis B virus(HBV)areas.Competing risk analysis was used to evaluate the effect of predispositions,including the etiology and severity of CLDs and precipitants;on sequential 28,90,and 365-day liver transplantation(LT)-free mortality.Results:Among all enrolled patients,76.8%of adverse outcomes(including death and LT)within one year occurred within 90 days.Compared with alcoholic etiology,the association of HBV etiology with poorer outcomes was remarkably on the 28th day(hazard ratio[HR],1.81;95%confidence interval[CI],1.07-3.06;p=0.026);however,and dimin-ished or became insignificant at 90 days and 365 days.Cirrhosis increased the adjusted risk for 365-day(HR,1.50;CI,1.13-1.99;p=0.004)LT-free mortality when compared with noncirrhosis.In patients with cirrhosis,prior decompensation(PD)independently increased the adjusted risk of 365-day LT-free mortality by 1.25-fold(p=0.021);however,it did not increase the risk for 90-day mortality.Neither the category nor the number of precipitants influenced the adjusted risk of 28 or 90-day LT-free mortality.Conclusions:The 90-day outcome should be considered a significant endpoint for evaluating the short-term prognosis of hospitalized patients with CLD.Predisposing factors,other than etiology,mainly affected the delayed(365-day)outcome.Timely effective therapy for CLD etiology,especially antiviral treatments for HBV,and post-discharge long-term surveillance monitoring in cirrhotic patients undergoing PD are suggested to enhance disease management and reduce mortality. | Yan Zhang Wenting Tan Xiaobo Wang Xin Zheng Yan Huang Beiling Li Zhongji Meng Yanhang Gao Zhiping Qian Feng Liu Xiaobo Lu Jia Shang Yubao Zheng Weituo Zhang Shan Yin Wenyi Gu Tongyu Wang Jianyi Wei Zixuan Shen Guohong Deng Yi Zhou Yixin Hou Qun Zhang Shue Xiong Jing Liu Liyuan Long Ruochan Chen Jinjun Chen Xiuhua Jiang Sen Luo Yuanyuan Chen Chang Jiang Jinming Zhao Liujuan Ji Xue Mei Jing Li Tao Li Rongjiong Zheng Xinyi Zhou Haotang Ren Yu Shi Hai Li for the CATCH‐LIFE Study Investigators of Chinese(Acute‐on)Chronic Liver Failure(CLIF)Consortium(Ch‐CLIFC) | 2023 | Portal Hypertension & Cirrhosis2023，2，3： | 0 |
| 20 | Effect of transport agent boron triiodide on the synthesis and crystal quality of boron arsenide显示文摘Cubic boron arsenide(BAs)has attracted great attention due to its high thermal conductivity,however,its controllable,stable,and ideal preparation remains challenging.Herein,we investigated the effect of iodine-containing transport agents I_(2) and boron triiodide(BI_(3))on BAs synthesized and grown through chemical vapor transport.Results show that similar to the commonly used I_(2),BI_(3) accelerates the synthesis and improves the mass fraction of BAs from ~12% to over 90% at 820℃ and 1.5 MPa,a value beyond the promoting effect of only increasing temperature and pressure.Both agents enhance the quality of BAs crystals by reducing the full width at half maximum by up to 10%-20%.I_(2) agglomerates the grown crystals with twin defects(~50 nm wide),and BI_(3) improves the crystal anisotropy and element uniformity of BAs crystals with narrow twins(~15 nm wide)and increases the stoichiometry ratio(~0.990)to almost 1.Owing to the boron interstitials from the excessive boron supply,the spacing of layers in {111} increases to 0.286 nm in the presence of I_(2).Owing to its coordinated effect,BI_(3) only slightly influences the layer spacing at 0.275 nm,which is close to the theoretical value of 0.276 nm.In the chemical vapor transport,the anisotropic crystals with flat surfaces exhibit single-crystal characteristics under the action of BI_(3).Different from that of I_(2),the coordinated effect of BI_(3) can promote the efficient preparation of high-quality BAs crystal seeds and facilitate the advanced application of BAs. | Zhenxing Liu Fangjie Deng Yuan Zhou Yanjie Liang Cong Peng Bing Peng Feiping Zhao Zhihui Yang Liyuan Chai | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，4： | 0 |
