| 1 | The investigation of internal solitary waves over a continental shelf-slope显示文摘Internal solitary waves(ISWs)always happen in marginal seas,where stable stratification exists.ISWs may carry large energy when they propagate and affect marine engineering constructions such as marine drilling platforms.Previous studies,including a large number of mooring observations and laboratory experiments,show the speed of ISWs will change when they pass by shelf slopes.Korteweg-de Vries(KdV)theory explain this phenomenon.In the paper,we use a laboratory experiment and a numerical model experiment to verify this theory.In the laboratory experiment,we injected two layers of water of different densities in a tank to simulate marine stratification and make ISWs.We use a CCD camera to record the whole process.The camera can take 16 photos per second.In the numerical experiment,we input the same original conditions as the laboratory one.The results of 18 different original conditions show the dimensionless factorδplays a key role in deciding the amplitudes and shapes of ISWs.The main conclusion also contains that small-amplitude waves match well with KdV theory while mKdV is better for largeamplitude waves.Whether the laboratory experiment or numerical experiment shows results with a high agreement.In future studies,we may use a numerical model with higher resolution to get analysis about phase speed and energy of ISWs. | MA Qian YUAN Chunxin LIN Xiaopei CHEN Xue’en | 2020 | Journal of Oceanology and Limnology2020，38，3： | 3 |

| 3 | Gas-liquid-liquid extraction in a novel rotating microchannel extractor显示文摘In this work,a novel rotating microchannel extractor(RME)is designed and further used for the extraction of chromium(Ⅲ)from water.Unexpectedly,the micro-extraction had the same effect as carrying out 2.9-stage cross-flow extractions.Various factors,including the gas intake methods,gas intake quantity(Qg),distance between inner rotor and outer wall(D),rotational inner rotor speed(R)and volumetric flow rate(Qa,Qo),were selected to investigate their effect on the extraction efficiency(η)thoroughly.The relation map ofηwith Weaand We(o-g)for RME provides a comprehension for the gas–liquid–liquid extraction process in this RME system. | Rui Ma Chunxin Fan Yubin Wang Jianhong Luo Jun Li Sridhar Komarneni | 2020 | Chinese Journal of Chemical Engineering2020，28，10： | 0 |
| 4 | In-situ polymerization for mechanical strong composite actuators based on anisotropic wood and thermoresponsive polymer显示文摘Stimuli-responsive hydrogels hold an irreplaceable statue in intelligent actuation materials because of their reversible stretchability and excellent biocompatibility.However,the poor mechanical performance and complicated fabrication process of anisotropic structures severely limit their further applications.Herein,we report a high-strength thermoresponsive wood-PNIPAM composite hydrogel actuator with complex deformations,through a simple in-situ polymerization.In this composite hydrogel actuator,the anisotropic wood and the thermoresponsive PNIPAM hydrogel hydroel can work together to pro-vide bending and even other complex deformations.Owing to strong interfacial interaction,this actuator perfectly realized the combination of good mechanical properties(∼1.1 MPa)and fast actuation speed(∼0.9 s).In addition,by adjusting the orientation direction of wood,this actuator can achieve various complex deformations.Such composite hydrogel actuator could be a good candidate for intelligent appli-cations,such as intelligent actuators,smart valves,manipulators and even soft robots. | Lian Chen Xianshuo Wei Feng Wang Shaoju Jian Weisen Yang Chunxin Ma Gaigai Duan Shaohua Jiang | 2022 | Chinese Chemical Letters2022，33，5： | 0 |
