1Bridging the injured spinal cord with neural stem cells显示文摘Spinal cord injury(SCI)damages not only the gray matter neurons,but also the white matter axonal tracts that carry signals to and from the brain,resulting in permanent loss of function below injury.Neural stem cells(NSCs)have high therapeutic potential for reconstruction of the injured spinal cord since they can potentially form neuronal relays to bridge functional connectivity between separated spinal cord segments.This requires host axonal regeneration into and connectivity with donor neurons,and axonal growth and connectivity of donor neurons to host central nervous system(CNS)circuitry.In this mini-review,we will discuss key studies that explore novel neuronal relay formation by grafting NSCs in models of SCI,with emphasis on long-distance axonal growth and connectivity of NSCs grafted into injured spinal cord.Jennifer N.

2Selective oxidation of biomass derived 5-hydroxymethylfurfural to 2,5-diformylfuran using sodium nitrite显示文摘A mild and simple process for the effective oxidation of 5-hydroxymethylfurfural(HMF) into 2,5-diformylfuran(DFF) has been developed using Na NO_2 as the oxidant. Some important reaction parameters were investigated to optimize the oxidation of HMF into DFF. It was found that the reaction solvent was very crucial for this reaction. Trifluoroacetic acid was the best solvent for the oxidation of HMF into DFF by Na NO_2.Under the optimal reaction condition, almost quantitative HMF conversion and high DFF yield of 90.4% were obtained after 1 h at room temperature.Xianxiang Liu Hui Ding Qiong Xu Wenzhou Zhong Dulin Yin Shengpei Su 2016Journal of Energy Chemistry2016,25,1:4
3Selective conversion of biomass-derived furfuryl alcohol into n-butyl levulinate over sulfonic acid functionalized TiO_(2) nanotubes显示文摘Sulfonic acid functionalized titanate nanotubes were prepared by the sulphonation reaction of hydrothermally synthesized TiO_(2) nanotubes(TNTs) using chlorosulfonic acid as the sulfating agent.The as-prepared catalysts were characterized by fourier transform infrared(FT-IR)spectroscopy,transmission electron microscopy(TEM),scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDX),Xray diffraction(XRD) analysis,thermogravimetry-differential thermal gravimetry(TG-DTG) and X-ray photoelectron spectroscopy(XPS)techniques.The characterization results revealed that the catalysts retained the tubular structure of the TNTs and possessed a large number of active sulfonic acid sites.The catalytic performance of the catalysts for the synthesis of n-butyl levulinate was investigated via the alcoholysis of biomass-derived furfuryl alcohol under atmospheric pressure.The effects of the reaction factors such as the catalyst dosage,reaction time,and temperature on the alcoholysis of the furfuryl alcohol were systematically studied.Under mild conditions,about 79.9% yield of n-butyl levulinate was achieved.In addition,the catalysts showed a stable catalytic performance after four consecutive cycles.Furthermore,no leaching of the active species was observed during the hot filtration testing,which can be attributed to the covalently linked –SO_(3)H groups on the TNTs surface.In addition,the opened tubular nanostructure of the catalyst and the introduced strong Br?nsted acid sites exhibited synergistic effects,which facilitated the selective conversion of the furfuryl alcohol to butyl levulinate.Shuolin Zhou Jinhua Lai Xianxiang Liu Geng Huang Gaolin You Qiong Xu Dulin Yin 2022Green Energy & Environment2022,7,2:3
4Efficient base-free oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid over copper-doped manganese oxide nanorods with tert-butanol as solvent显示文摘2,5-Furandicarboxylic acid(FDCA)is an important and renewable building block and can serve as an alternative to terephthalic acid in the production of biobased degradable plastic.In this study,Cu-doped MnO_(2) nanorods were prepared by a facile hydrothermal redox method and employed as catalysts for the selective oxidation of 5-hydroxymethylfurfural(HMF)to FDCA using tert-butyl hydroperoxide(TBHP)as an oxidant.The catalysts were characterized using X-ray diffraction analysis,Fourier transform infrared spectroscopy,thermo-gravimetric analysis,and transmission electron microscopy.The effects of oxidants,solvents,and reaction conditions on the oxidation of HMF were investigated,and a reaction mechanism was proposed.Experimental results demonstrated that 99.4% conversion of HMF and 96.3% selectivity of FDCA were obtained under suitable conditions,and tert-butanol was the most suitable solvent when TBHP was used as an oxidant.More importantly,the Cu-doped MnO_(2) catalyst can maintain durable catalytic activity after being recycled for more than ten times.Feng Cheng Dongwen Guo Jinhua Lai Meihui Long Wenguang Zhao Xianxiang Liu Dulin Yin 2021Frontiers of Chemical Science and Engineering2021,15,4:2
5The first joint experimental results between SURA and CSES显示文摘In June 2018, for the first time, the SURA heating facility in Russia, together with the in-orbit China Seismo-Electromagnetic Satellite(CSES), carried out a series of experiments in emitting high frequency(HF) O-mode radio waves to disturb the ionosphere. This paper reports data from those experiments, collected onboard CSES, including electric field, in-situ plasma parameters, and energetic particle flux. Five cases are analyzed, two cases in local daytime and three in local nighttime. We find that the pumping wave frequencies f_0 in local daytime were close to the critical frequency of the F_2 layer f_oF_2, but no pumping waves were detected by the electric field detector(EFD) on CSES even when the emitted power reached 90 MW, and no obvious plasma disturbances were observed from CSES in those two daytime cases. But on June 16, there existed a spread F phenomena when f_0 was lower than f_oF_2 at that local daytime period.During the three cases in local nighttime, the pumping waves were clearly distinguished in the HF-band electric field at the emitted frequency with the emitted power only 30 MW; the power spectrum density of the electric field was larger by an order of magnitude than the normal background, with the propagating radius exceeding 200 km. Due to the small f_oF_2 over SURA in June at that local nighttime period, f_0 in these three cases were significantly higher than f_oF_2, all belonging to under-dense heating conditions. As for the plasma parameters, only an increase of about 100 K in ion temperature was observed on June 12; in the other two cases(with one orbit without plasma data on June 17), no obvious plasma disturbances were found. This first joint SURA-CSES experiment illustrates that the present orbit of CSES can cross quite close to the SURA facility, which can insure an effective heating time from SURA so that CSES can observe the perturbations at the topside ionosphere excited by SURA in the near region. The detection of plasma disturbances on June 12 with under-dense heating mode in local nighttime provides evidence for likely success of future related experiments between CSES and SURA,or with other HF facilities.XueMin Zhang Vladimir Frolov ShuFan Zhao Chen Zhou YaLu Wang Alexander Ryabov DuLin Zhai 2018Earth and Planetary Physics2018,2,6:2
