| 1 | A fully biodegradable polydioxanone occluder for ventricle septal defect closure显示文摘Ventricular septal defect(VSD)is one of the commonest congenital heart diseases(CHDs).Current occluders for VSD treatment are mainly made of nitinol,which has the risk of nickel allergy,persistent myocardial abrasion and fatal arrythmia.Herein,a fully biodegradable polydioxanone(PDO)occluder equipped with a shape line and poly-L-lactic acid PLLA membranes is developed for VSD closure without the addition of metal marker.PDO occluder showed great mechanical strength,fatigue resistance,geometry fitness,biocompatibility and degradability.In a rat subcutaneous implantation model,PDO filaments significantly alleviated inflammation response,mitigated fibrosis and promoted endothelialization compared with nitinol.The safety and efficacy of PDO occluder were confirmed in a canine VSD model with 3-year follow-up,demonstrating the biodegradable PDO occluder could not only effectively repair VSD,induce cardiac remodeling but also address the complications associated with metal occluders.Furthermore,a pilot clinical trial with five VSD patients indicated that all the occluders were successfully implanted under the guidance of echocardiography and no adverse events occurred during the 3-month follow-up.Collectively,the fully bioresorbable PDO occluder is safe and effective for clinical VSD closure and holds great promise for the treatment of structural CHDs. | Zefu Li Pengxu Kong Xiang Liu Shuyi Feng Wenbin Ouyang Shouzheng Wang Xiaopeng Hu Yongquan Xie Fengwen Zhang Yuxin Zhang Rui Gao Weiwei Wang Xiangbin Pan | 2023 | Bioactive Materials2023，，6： | 1 |
| 2 | Light-Induced Heat Driving Active Ion Transport Based on 2D MXene Nanofluids for Enhancing Osmotic Energy Conversion显示文摘Osmotic energy from the ocean,also called blue energy,serves as a clean,renewable,and vast energy source for the energy demands of the world.Reverse electrodialysis-based blue energy harvesting via ion-selective membranes,by the regulation and manipulation of directional ion transport,has been greatly developed recently.In particular,light has been employed to enhance directional ion transport for energy conversion through an increase in photo-induced surface charge.Here,the authors demonstrate a novel nanofluidic regulation strategy based on the phenomenon of light-induced heat-driven active ion transport through the lamellar MXene membrane.Due to the great light-induced heat effect,a temperature gradient appears as soon as illumination is applied to an off-center position,inducing an actively temperature gradient-driven ionic species transport.By employing this phenomenon,the authors conducted light-induced heat-enhanced osmotic energy conversion and doubled the osmotic energy conversion power density.This study has extended the scope of light-enhanced osmotic energy conversion and could further bring other photothermal materials into this field.Furthermore,the proposed system provides a new avenue of light-controlled ionic transport for ion gathering,desalination,and energy conversion applications. | Pei Liu Teng Zhou Yunfei Teng Lin Fu Yuhao Hu Xiangbin Lin Xiang-Yu Kong Lei Jiang Liping Wen | 2021 | CCS Chemistry2021，3，4： | 1 |

| 5 | Engineering Multi‑field‑coupled Synergistic Ion Transport System Based on the Heterogeneous Nanofluidic Membrane for High‑Efficient Lithium Extraction显示文摘The global carbon neutrality strategy brings a wave of rechargeable lithium‐ion batteries technique development and induces an ever-growing consumption and demand for lithium(Li).Among all the Li exploitation,extracting Li from spent LIBs would be a strategic and perspective approach,especially with the low energy consumption and eco-friendly membrane separation method.However,current membrane separation systems mainly focus on monotonous membrane design and structure optimization,and rarely further consider the coordination of inherent structure and applied external field,resulting in limited ion transport.Here,we propose a heterogeneous nanofluidic membrane as a platform for coupling multi-external fields(i.e.,lightinduced heat,electrical,and concentration gradient fields)to construct the multi-field-coupled synergistic ion transport system(MSITS)for Li-ion extraction from spent LIBs.The Li flux of the MSITS reaches 367.4 mmol m^(−2)h^(−1),even higher than the sum flux of those applied individual fields,reflecting synergistic enhancement for ion transport of the multi-field-coupled effect.Benefiting from the adaptation of membrane structure and multi-external fields,the proposed system exhibits ultrahigh selectivity with a Li^(+)/Co^(2+)factor of 216,412,outperforming previous reports.MSITS based on nanofluidic membrane proves to be a promising ion transport strategy,as it could accelerate ion transmembrane transport and alleviate the ion concentration polarization effect.This work demonstrated a collaborative system equipped with an optimized membrane for high-efficient Li extraction,providing an expanded strategy to investigate the other membrane-based applications of their common similarities in core concepts. | Lin Fu Yuhao Hu Xiangbin Lin Qingchen Wang Linsen Yang Weiwen Xin Shengyang Zhou Yongchao Qian Xiang‑Yu Kong Lei Jiang Liping Wen | 2023 | Nano-Micro Letters2023，15，8： | 1 |

| 9 | Simulation and experiment of starting transient flow field of the hydrostatic bearing based on dynamic mesh method显示文摘A new method is developed to assess and analyze the dynamic performance of hydrostatic bearing oil film by using an amulets-layer dynamic mesh technique. It is implemented using C Language to compile the UDF program of a single oil film of the hydrostatic bearing. The effects of key lubrication parameters of the hydrostatic bearing are evaluated and analyzed under various working conditions,i.e. under no-load,a load of 40 t,a full load of 160 t,and the rotation speed of 1r/min,2r/min,4r/min,8r/min,16r/min,32r/min. The transient data of oil film bearing capacity under different load and rotation speed are acquired for a total of 18 working conditions during the oil film thickness changing. It allows the effective prediction of dynamic performance of large size hydrostatic bearing. Experiments on hydrostatic bearing oil film have been performed and the results were used to define the boundary conditions for the numerical simulations and validate the developed numerical model. The results showed that the oil film thickness became thinner with the increase of the operating time of the hydrostatic bearing,both the oil film rigidity and the oil cavity pressure increased significantly,and the increase of the bearing capacity was inversely proportional to the cube of the change of the film thickness. Meanwhile,the effect of the load condition on carrying capacity of large size static bearing was more important than the speed condition. The error between the simulation value and the experimental value was 4.25%. | 张艳芹 Kong Xiangbin Guo Lili Yu Xiaodong Dai Chunxi Shao Junpeng | 2017 | High Technology Letters2017，23，3： | 0 |
