1High-performance SSZ-13 membranes prepared using ball-milled nanosized seeds for carbon dioxide and nitrogen separations from methane显示文摘SSZ-13 membranes with high separation performances were prepared using ball-milled nanosized seeds by once hydrothermal synthesis.Separation performances of SSZ-13 membranes in CO2/CH4 and N2/CH4 mixtures were enhanced after synthesis modification.Single-gas permeances of CO2,N2 and CH4 and ideal selectivities were recorded through SSZ-13 membranes.The effects of temperature,pressure,feed flow rate and humidity on separation performance of the membranes were discussed.Three membranes prepared after synthesis modifications had an average CO2 permeance of 1.16×10-6 mol·(m2·s·Pa)-1(equal to 3554 GPU)with an average CO2/CH4 selectivity of 213 in a 50 vol%/50 vol%CO2/CH4 mixture.It suggests that membrane synthesis has a good reproducible.The membrane also displayed a N2 permeance of 1.07×10-7 mol·(m2·s·Pa)-1(equal to 320 GPU)with a N2/CH4 selectivity of 13 for a 50 vol%/50 vol%N2/CH4 mixture.SSZ-13 membrane displayed stable and good separation performance in the wet CO2/CH4 mixture for a long test period over 100 h at 348 K.The current SSZ-13 membranes show great potentials for the simultaneous removals of CO2 and N2 in natural gas purification as a facile process suitable for industrial application.Xinping Li Yaowei Wang Tangyin Wu Shichao Song Bin Wang Shenglai Zhong Rongfei Zhou 2020Chinese Journal of Chemical Engineering2020,28,5:3
2The Matrix Stiffness and Physical Confinement of Hydrogel Microchannel Jointly Induce the Mesenchymal-Amoeboid Transition for Cancer Cell Migration显示文摘The migration mode transition of cancer cell enhances its invasive capability and the drug resistance,where physical confinement of cell microenvironment has been revealed to induce the mesenchymal-amoeboid transition(MAT).However,most existing studies are performed in PDMS microchannels,of which the stiffness is much higher than that of most mammalian tissues.Therefore,the amoeboid migration transition observed in these studies is actually induced by the synergistic effect of matrix stiffness and confinement.Since the stiffness of cell microenvironment has been reported to influence the cell migration in 2D substrate,the decoupling of stiffness and confinement effects is thus in need for elucidating the underlying mechanism of MAT.However,it is technically challenging to construct microchannels with physiologically relevant stiffness and channel size,where existing microchannel platforms with physiological relevance stiffness are all with>10μm channel width.Such size is too wide to mimic the physical confinement that migrating cancer cells confront in vivo,and also larger than the width of PDMS channel,in which the MAT of cancer cell was observed.Therefore,an in vitro cell migration platform,which could mimic both stiffness and confinement of the native physical microenvironment during cancer metastasis,could profoundly contribute to researches on cancer cell migration and cellular mechanotransduction.In this paper,we overcome the limitations of engineering soft materials in microscale by combining the collagen-alginate hydrogel with photolithography.This enables us to improve the accuracy of molded microchannel,and thus successfully construct a 3D microchannel platform,which matches the stiffness and width ranges of native environmental confinement that migrating cancer cells confront in vivo.The stiffness(0.3~20 kPa),confinement(channel width:3.5~14μm)and the adhesion ligand density of the microchannel can be tuned independently.Interestingly,using this platform,we observed that the migration speed of cancer cell is influenced by the synergistic effect of channel stiffness and width,and the increasing stiffness reverses the effect of channel width on the migration speed of cancer cells.In addition,MAT has a strong correlation with the channel stiffness.These findings make us reconsider the widely accepted hypothesis:physical confinement can induce MAT.Actually,this transition can only occur in stiff confined microenvironment not in soft one.For soft microchannels,the compliance of the channel walls could cause little cell/nucleus deformation,and the MAT could not be induced.To further investigate the mechanism of MAT,we developed a computational model to simulate the effect of nucleus deformation on MAT.With the model,we found that deforming the cell nuclear by decreasing the nucleus stiffness will reduce the cellmigration speed.This implies that nuclear stiffness plays an important role in the regulation of cancer migration speed and thus MAT in microchannels.The effect of channel stiffness on MAT and migration speed as observed in our experiment could partially explain previous findings reported in the literature,where the increasing matrix stiffness of tumor microenvironment promotes cancer metastasis.Our observations thus highlight the critical role of cell nuclear deformation not only in MAT,but also in regulating cellular mechanotransduction and cell-ECM interactions.This developed platform is capable of mimicking the native physical microenvironment during metastasis,providing a powerful tool for high-throughput screening applications and investigating the interaction between cancer migration and biophysical microenvironment.Meng Wang Bo Cheng Yaowei Yang Han Liu Guoyou Huang Fei Li Feng Xu 2019医用生物力学2019,34,A01:2
3High-zirconium bulk metallic glasses with high strength and large ductility显示文摘In this paper,high-zirconium Zr66+2xAl9-x(Ni1/3Cu2/3) 25-x(x=0,1,2 at.%) bulk metallic glasses with high strength and large ductility were fabricated by copper mould casting.The effects of zirconium content on the glass-forming ability(GFA),thermal properties and mechanical properties were investigated using X-ray diffractometer(XRD),differential scanning calorimeter(DSC),and mechanical testing system in compressive and three-point bending modes,respectively.The high-zirconium BMGs show the critical diameters of 3-5 mm,the supercooled liquid region ranging from 70 K to 99 K,and the yield strength of over 1700 MPa.The Zr 70 Al 7(Ni1/3Cu2/3) 23 BMG exhibits a large compressive plastic strain up to 21% and a high notch toughness value of 60.6 MPa m 1/2.The increase in Zr content results in the decrease in GFA and thermostability,and in the improvement of plasticity under compressive and three-point bending conditions.The superior plasticity of high-zirconium BMGs is attributed to their high Poisson's ratio and small elastic modulus ratio /B.YANG YaoWei HUA NengBin LI Ran PANG ShuJie ZHANG Tao 2013Science China Chemistry2013,56,3:2

5Generation of VP5 deficient mutant of infectious bursal disease virus strain HZ2显示文摘Infectious bursal disease virus (IBDV) is a bi-segmented, dsRNA virus of the Birnaviridae family. The nonstructural protein VP5 has been re- ported to be associated with virus-induced cell apoptosis and pathogenicity, but its role in viral rep- lication has not been unequivocally identified. Based on a PCR introduced mutagenesis strategy, the 33 bp of 96―129 bp located between ORF A1and ORF A2 of genomic segment A of IBDV strain HZ2 were de- leted, and an Nhe I (GcTaGc) site was inserted at 96―102 bp simultaneously. The mutated segment A was ligated into pCI, resulting in pCI-ANhe3. A chi- meric and deficient IBDV strain, named strain ANhe3, was recovered from chicken embryo fibroblast (CEF) cells by co-transfection with pCI-ANhe3 and pCI-mB, derived from the genomic segment B strain HZ2. The indirect fluorescent assay identified that strain ANhe3 could replicate on CEF cells without expression of VP5. Further examination showed that the patho- genesis of strain ANhe3 replicating on SPF chicken embryos was attenuated compared to strain HZ2. This paper provides a new rapid rescue strategy for gene-deleted virus. This strategy lays a basis for gene-deleted vaccine of IBDV.LI Long WEI Yongwei HUANG Yaowei YU Lian 2006Chinese Science Bulletin2006,51,15:1

11Formation and mechanical properties of Zr-based bulk metallic glass composites with high oxygen levels显示文摘Zr-based bulk metallic glass(BMG) composites with in situ formed Y 2 O 3 particle reinforcements were synthesized by proper additions of Y to ultrahigh-oxygen-containing glass-forming alloy precursors.Microstructures,thermal stabilities,and mechanical properties of the composites were investigated.Glass formation was greatly enhanced by Y additions in the alloys and the resultant particles were homogenously distributed in the glassy matrix,allowing for the fabrication of oxide dispersion strengthened BMG composites.The compressive strength and hardness increased by 10% and 20%,respectively,with the introduction of Y 2 O 3 particles.These results are significant for the design and production of Zr-based BMGs and BMG composites with improved properties using commercial high-oxygen content raw materials under industrial conditions.LIU ZengQian YANG YaoWei LI Ran HUANG Lu ZHANG Tao 2012Chinese Science Bulletin2012,57,30:0
12Ball-milled bismuth oxychloride/biochar nanocomposites with rich oxygen vacancies for reactive red-120 adsorption in aqueous solution显示文摘Fabricating surface oxygen vacancies is considered to be an efficient method to improve the adsorption performance of sorbents.In this work,a bismuth oxychloride/biochar(BiOCl/BC)nanocomposite with abundant oxygen vacancies was successfully prepared by a facile ball milling method.BiOCl/BC nanocomposite was found to have excellent adsorption performance for removing reactive red-120(RR120)from aqueous solution.The effects of key adsorption parameters,such as RR120 dye concentration,solution pH(2-10),and contact time were studied by batch adsorption test.The adsorption data were well described by the Langmuir and Freundlich isotherms and pseudo-second-order kinetic models.The 50%-BiOCl/BC(50 wt%of BiOCl in composite)exhibited the best adsorptive performance(60%),much better than the pristine BM-BC(20%).The high adsorption capacity of 50%-BiOCl/BC(Langmuir maximum capacity of 116.382 mg g^(−1))can be attributed to the electrostatic effect,π-πinteractions,and hydrogen bond.This work provided a facile method to prepare semiconductor assisted biochar-based adsorbents,which would also contribute to the advance of environmental remediation.Yidan Luo Yonghu Wang Yaowei Zhu Mingshan Xue Aofeng Zheng Yu Han Zuozhu Yin Zhen Hong Chan Xie Xibao Li Sheng Lei Bin Gao 2022Biochar2022,4,1:0
13Cell metabolism pathways involved in the pathophysiological changes of diabetic peripheral neuropathy显示文摘Diabetic peripheral neuropathy is a common complication of diabetes mellitus.Elucidating the pathophysiological metabolic mechanism impels the generation of ideal therapies.However,existing limited treatments for diabetic peripheral neuropathy expose the urgent need for cell metabolism research.Given the lack of comprehensive understanding of energy metabolism changes and related signaling pathways in diabetic peripheral neuropathy,it is essential to explore energy changes and metabolic changes in diabetic peripheral neuropathy to develop suitable treatment methods.This review summarizes the pathophysiological mechanism of diabetic peripheral neuropathy from the perspective of cellular metabolism and the specific interventions for different metabolic pathways to develop effective treatment methods.Various metabolic mechanisms(e.g.,polyol,hexosamine,protein kinase C pathway)are associated with diabetic peripheral neuropathy,and researchers are looking for more effective treatments through these pathways.Yaowei Lv Xiangyun Yao Xiao Li Yuanming Ouyang Cunyi Fan Yun Qian 2024Neural Regeneration Research2024,19,3:0
14Investigation on the granulation behavior of iron ore fine in a horizontal high-shear granulator显示文摘High-shear granulation is widely used in many particulate industries for its good capability to improve the size,strength and composition uniformity of powder substances.This work conducted an experimental study to investigate the granulation behavior of iron ore fine in a horizontal high-shear granulator,such as granules size distribution,granules growth rate,and permeability of the granules bed.The results show that the granule size and permeability of packed granules bed increase gradually with increasing the granulation time,and the growth of granules can be divided into three stages:the rapid growth stage,the slow growth stage and the relatively stable stage.Both the higher rotational speed and larger number of impellers increase the kinetic energy and collision frequency of the particles,which causes the increase of average granule size,growth rate and permeability of granules packed bed.On the other hand,the shear damage effect of the impellers on the granules is also enhanced with the increase of rotational speed and impeller number,resulting in significant granule size segregation.Yang You Jiabao Guo Gang Li Zhuang Zheng Yong Li Yaowei Yu Xuewei Lv 2022Particuology2022,20,9:0
15Management of traumatic peripheral artery pseudoaneurysm:A 10-year experience at a single center显示文摘Purpose: This study aimed to report our 10-year experience with the management of iatrogenic(penetrating trauma) and traumatic(blunt or penetrating trauma) peripheral artery pseudoaneurysms, based on data from a tertiary referral center.Methods: From January 2012 to December 2021, the medical records of consecutive patients with iatrogenic and traumatic peripheral artery pseudoaneurysms were retrospectively reviewed. Patient demographics, clinical features, imaging data, treatment details, and follow-up results were analyzed.Results: Sixty-one consecutive patients were included in this study;48(79%) were men and 13(21%) women,with a mean age of 49.4 ± 13.4 years(range 24–73 years). There were 42 patients(69%) who underwent open surgery, 18(29%) undergoing endovascular embolization or stent implantation, and one(2%) undergoing ultrasound-guided thrombin injection. All patients successfully underwent open or interventional treatment. The median follow-up was 46.8 months(2.5–117.9 months), and the overall reintervention rate was 10%. Of these,one(5%) patient in the interventional treatment group and five(12%) patients in the open surgery group underwent reintervention. The overall complication rate was 8%, with complications occurring only in the open surgery group. No deaths occurred in the peri-operative period. No late complications, such as thrombosis or pseudoaneurysm recurrence, were observed.Conclusion: Peripheral artery pseudoaneurysms arising from iatrogenic or traumatic causes can be effectively treated by both open surgery and interventional procedures in selected patients with acceptable mid-and long-term outcomes.Yingliang Wang Hai Zheng Wei Yao Shuguang Ju Yaowei Bai Chaoyang Wang Chen Zhou Jiacheng Liu Chongtu Yang Songjiang Huang Tongqiang Li Yang Chen Bin Xiong 2023Journal of Interventional Medicine2023,6,1:0
16Enrichment of anchoring sites by introducing supramolecular halogen bonds for the efficient perovskite nanocrystal LEDs显示文摘Considering the multi-functionalization of ligands,it is crucial for ligand molecular design to reveal the landscape of anchoring sites.Here,a typical triphenylphosphine(TPP)ligand was employed to explore its effect on the surface of CsPbI_(3)perovskite nanocrystals(PNCs).Except for the conventionally considered P-Pb coordination,an P-I supramolecular halogen bonding was also found on the NC surface.The coexistence of the above two types of bonding significantly increased the formation energy of iodine vacancy defects and improved the photoluminescence quantum yield of PNCs up to 93%.Meanwhile,the direct interaction of P and I enhanced the stability of the Pb-I octahedra and dramatically inhibited the migration of I ions.Furthermore,the introduction of additional benzene rings(2-(Diphenylphosphino)-biphenyl(DPB))increased the delocalized properties of the PNC surface and significantly improved the charge transport of the PNCs.As a result,the DPB passivated CsPbI_(3)NCs based top-emitting LEDs exhibite a peak external quantum efficiency(EQE)of 22.8%,a maximum luminance of 15,204 cd m^(−2),and an extremely low-efficiency roll-off of 2.6%at the current density of 500 mA cm^(−2).Po Lu Ting Li Min Lu Cheng Ruan Siqi Sun Zhennan Wu Yuan Zhong Fujun Zhang Yanbo Gao Yaowei Huang Yang Wang Junhua Hu Fengping Yan Yu Zhang 2023Light(Science & Applications)2023,12,10:0
