| 3 | Silicalite-1 zeolite encapsulated Fe nanocatalyst for Fenton-like degradation of methylene blue显示文摘Encapsulation of Fe nanoparticles in zeolite is a promising way to significantly improve the catalytic activity and stability of Fe-based catalysts during the degradation process of organic pollutants.Herein,Fe nanocatalysts were encapsulated into silicalite-1(S-1)zeolite by using a ligand-protected method(with dicyandiamide(DCD)as a organic ligand)under direct hydrothermal synthesis condition.High-resolution transmission electron microscopy(HRTEM)results confirmed the high dispersion of Fe nanocatalysts which were successfully encapsulated within the voids among the primary particles of the S-1 zeolite.The developed S-1 zeolite encapsulated Fe nanocatalyst(Fe@S-1)exhibited significantly improved catalytic activity and reusability in the catalytic degradation process of methylene blue(MB).Specifically,the developed Fe0.021@S-1 catalyst showed high catalytic degradation activity,giving a high MB degradation efficiency of 100%in 30 min,outperformed the conventional impregnated catalyst(Fe/S-1).Moreover,the Fe@S-1 catalyst afforded an outstanding stability,showing only ca.7.9%activity loss after five cycling tests,while the Fe/S-1 catalyst presented a significantly activity loss of 50.9%after only three cycles.Notably,the encapsulation strategy enabled a relatively lower Fe loading in the Fe@S-1 catalyst in comparison with that of the Fe/S-1 catalyst,i.e.,0.35%vs.0.81%(mass).Radical scavenging experiments along with electron spin resonance(ESR)measurements confirmed that the major role ofOH in the MB degradation process.Specifically,Fe@S-1 catalyst with high molar ratio of[Fe(DCD)]Cl3 is beneficial to form Fe complexes/nanoclusters in the voids(which has large pore size of 1–2 nm)among the primary particles of the zeolite,and thus improving the diffusion and accessibility of reactants to Fe active sites,and thus exhibiting a relatively higher degradation efficiency.This work demonstrates that zeolite-encapsulated Fe nanocatalysts present potential applications in the advanced oxidation of wastewater treatment. | Hongwei Guo Linyuan Chen Xueying Zhang Huanhao Chen Yan Shao | 2023 | Chinese Journal of Chemical Engineering2023,53,1: | 0 |
| 4 | Improving the estimation of canopy cover from UAV-LiDAR data using a pit-free CHM-based method显示文摘Accurate and rapid estimation of canopy cover(CC)is crucial for many ecological and environmental models and for forest management.Unmanned aerial vehicle-light detecting and ranging(UAV-LiDAR)systems represent a promising tool for CC estimation due to their high mobility,low cost,and high point density.However,the CC values from UAV-LiDAR point clouds may be underestimated due to the presence of large quantities of within-crown gaps.To alleviate the negative effects of within-crown gaps,we proposed a pit-free CHM-based method for estimating CC,in which a cloth simulation method was used to fill the within-crown gaps.To evaluate the effect of CC values and withincrown gap proportions on the proposed method,the performance of the proposed method was tested on 18 samples with different CC values(40−70%)and 6 samples with different within-crown gap proportions(10−60%).The results showed that the CC accuracy of the proposed method was higher than that of the method without filling within-crown gaps(R^(2)=0.99 vs 0.98;RMSE=1.49%vs 2.2%).The proposed method was insensitive to within-crown gap proportions,although the CC accuracy decreased slightly with the increase in withincrown gap proportions. | Shangshu Cai Wuming Zhang Shuangna Jin Jie Shao Linyuan Li Sisi Yu Guangjian Yan | 2021 | International Journal of Digital Earth2021,14,10: | 0 |
| 5 | MSCs-derived apoptotic extracellular vesicles promote muscle regeneration by inducing Pannexin 1 channel-dependent creatine release by myoblasts显示文摘Severe muscle injury is hard to heal and always results in a poor prognosis.Recent studies found that extracellular vesicle-based therapy has promising prospects for regeneration medicine,however,whether extracellular vesicles have therapeutic effects on severe muscle injury is still unknown.Herein,we extracted apoptotic extracellular vesicles derived from mesenchymal stem cells(MSCs-Apo EVs)to treat cardiotoxin induced tibialis anterior(TA)injury and found that MSCs-Apo EVs promoted muscles regeneration and increased the proportion of multinucleated cells.Besides that,we also found that apoptosis was synchronized during myoblasts fusion and MSCs-Apo EVs promoted the apoptosis ratio as well as the fusion index of myoblasts.Furthermore,we revealed that MSCs-Apo EVs increased the relative level of creatine during myoblasts fusion,which was released via activated Pannexin 1 channel.Moreover,we also found that activated Pannexin 1 channel was highly expressed on the membrane of myoblasts-derived Apo EVs(Myo-Apo EVs)instead of apoptotic myoblasts,and creatine was the pivotal metabolite involved in myoblasts fusion.Collectively,our findings firstly revealed that MSCs-Apo EVs can promote muscle regeneration and elucidated that the new function of Apo EVs as passing inter-cell messages through releasing metabolites from activated Pannexin 1 channel,which will provide new evidence for extracellular vesicles-based therapy as well as improving the understanding of new functions of extracellular vesicles. | Qingyuan Ye Xinyu Qiu Jinjin Wang Boya Xu Yuting Su Chenxi Zheng Linyuan Gui Lu Yu Huijuan Kuang Huan Liu Xiaoning He Zhiwei Ma Qintao Wang Yan Jin | 2023 | International Journal of Oral Science2023,15,1: | 0 |
| 6 | Structural and electronic effects boosting Ni-doped Mo_(2)C catalyst toward high-efficiency C-O/C-C bonds cleavage显示文摘The selective cleavage of C-O and C-C is facing a challenge in the field of catalysis.In the present work,we studied the influence of doped Ni on the structure and electronic properties,as well as the selective C-O/C-C bond cleavages in the hydrodeoxygenation of palmitic acid over Ni-Mo_(2)C catalyst.The catalytic activity on Ni doped Mo_(2)C with TOF of 6.9×10^(3)h^(-1)is much superior to intrinsic Mo_(2)C catalyst,which is also higher than most noble metal catalysts.Structurally,the doped Ni raises the active particle dispersion and the coordination numbers of Mo species(Mo-C and Mo-O),improves the graphitization degree to promote the electron transfer,and increases the amount of Lewis and Br?nsted acid,which are responsible for the excellent hydrodeoxygenation performance.The Ni promotes simultaneously C-O and C-C bonds cleavage to produce pentadecane and hexadecane owing to the increase of electron-rich Mo sites after Ni doping.These findings contribute to the understanding of the nature of Ni-doped Mo_(2)C on the roles as catalytic active sites for C-O and C-C bonds cleavage. | Xiangze Du Jinjia Liu Dan Li Hui Xin Xiaomei Lei Rui Zhang Linyuan Zhou Huiru Yang Yan Zeng Hualong Zhang Wentao Zheng Xiaodong Wen Changwei Hu | 2022 | Journal of Energy Chemistry2022,,12: | 0 |
| 7 | 乡土草本植物对入侵植物薇甘菊的防控显示文摘薇甘菊(Mikania micrantha)是在太平洋岛屿和亚洲热带亚热带发现的一种入侵植物。目前防治薇甘菊的方法并不完善,因此亟需寻找对环境友好的、更有效的防治方法。因此,我们探究了4种草本植物对薇甘菊入侵的防御能力,以期为薇甘菊的生态可持续防治提供科学依据。本研究选取了4种来自中国本土的多年生禾本科草本植物:藤竹草(Panicum incomtum)、象草(Pennisetum purpureum)、斑茅(Saccharum arundinaceum)和蔓生莠竹(Microstegium vagans)来构建草丛。将薇甘菊种子播种在上述草丛中,同时还将薇甘菊幼苗移栽到上述草丛中,观察草丛是否能阻止薇甘菊幼苗的生长。此外,我们还将薇甘菊移植到现有的草丛中,观察草丛是否能够阻止薇甘菊的再次入侵。最后还在野外将薇甘菊分别与藤竹草和象草一同种植,探究这两种禾本科植物是否能在竞争中胜出。研究结果表明,薇甘菊种子在上述草丛中萌发困难,所有薇甘菊幼苗在3个月内死亡,说明薇甘菊很难在现有的草丛中生存。野外实验表明,薇甘菊盖度在第一年显著低于这些草本植物,两年后全部被这些草本植物取代。据我们所知,本研究首次揭示了高大草本植物,特别是藤竹草和象草,具有作为薇甘菊生物防治的潜力。 | Sheng Zhou Min Wang Linglong Yuan Hao Chen Linyuan Yan Sitong Yao Bipei Zhang | 2022 | Journal of Plant Ecology2022,15,4: | 0 |
