Weak magnetic field accelerates chromate removal by zero-valent iron

Feng, Pian,Guan, Xiaohong,Sun, Yuankui,Choi, Wonyong,Qin, Hejie,Wang, Jianmin,Qiao, Junlian,Li, Lina Elsevier 2015 Journal of environmental sciences Vol.31 No.-

<P>Weak magnetic field (WMF) was employed to improve the removal of Cr(VI) by zero-valent iron (ZVI) for the first time. The removal rate of Cr(VI) was elevated by a factor of 1.12-5.89 due to the application of a WMF, and the WMF-induced improvement was more remarkable at higher Cr(VI) concentration and higher pH. Fe2+ was not detected until Cr(VI) was exhausted, and there was a positive correlation between the WMF-induced promotion factor of Cr(VI) removal rate and that of Fe2+ release rate in the absence of Cr(VI) at pH4.0-5.5. These phenomena imply that ZVI corrosion with Fe2+ release was the limiting step in the process of Cr(VI) removal. The superimposed WMF had negligible influence on the apparent activation energy of Cr(VI) removal by ZVI, indicating that WMF accelerated Cr(VI) removal by ZVI but did not change the mechanism. The passive layer formed with WMF was much more porous than without WMF, thereby facilitating mass transport. Therefore, WMF could accelerate ZVI corrosion and alleviate the detrimental effects of the passive layer, resulting in more rapid removal of Cr(VI) by ZVI. Exploiting the magnetic memory of ZVI, a two-stage process consisting of a small reactor with WMF for ZVI magnetization and a large reactor for removing contaminants by magnetized ZVI can be employed as a new method of ZVI-mediated remediation.</P>

Anti-seismic Effect of Lattice Grid Structure with Friction Pendulum Bearings Under the Earthquake Impact of Various Dimensions

Feng Fan,Dewen Kong,Menghan Sun,Xudong Zhi 한국강구조학회 2014 International Journal of Steel Structures Vol.14 No.4

As a typical base isolation device, the friction pendulum bearing (FPB) was applied to the lattice grid structures in this paper. The isolation mechanism of FPBs was analyzed from two aspects of force and energy consumption, while the static anddynamic mechanical properties of lattice grid structures with FPBs were numerically investigated using two models of regularand oblique quadrangular pyramid framed structures. The physical models of FPBs with fictional coefficient of 0.1 and acurvature radius of 1.0 m was established and applied to the lattice grid structures. Moreover, the mechanical properties of thesestructures with FPBs ware studied. Numerical results indicate that the seismic response of structures is remarkably weakenedby using FPBs, which means FPBs can be used to effectively control structural vibration.

Molecular and cellular mechanism of neuroprotection by vascular endothelial growth factor against ischemic/hypoxic injury

Sun, Feng-Yan,Qiu, Mei-Hong,Xu, Jian-Yi,Yan, Zeng-Jin 한림대학교 환경·생명과학연구소 2003 [일송 국제심포지엄] 노화와 만성퇴행성 신경질환 Vol.- No.5

Vascular endothelial growth factor (VEGF), a dimeric glycoprotein, is original found in the vascular endothelial cells with high potency of angiogenesis, vascular permeability and endothelial proliferation. However, VEGF also could be detected in the culture neuronal astrocytes, cardiac myocytes and cornea, which did not associate with neovascularization. In the brain, VEGF expression was observed in the neuronal cells in the postnatal and adult rats. Functional study demonstrated exogenous VEGF could enhance the axonal outgrowth and neuronal survival against hypoxic neuronal damage. Therefore, in the past several years, we further studied the neuroprotective mechanism of endogenous and exogenous VEGF against ischemic neuronal injury with morphological, electrical physiological and biochemical approaches in in vivo and in vitro studies as follows.

Sol-Flame Synthesis: A General Strategy To Decorate Nanowires with Metal Oxide/Noble Metal Nanoparticles

Feng, Yunzhe,Cho, In Sun,Rao, Pratap M.,Cai, Lili,Zheng, Xiaolin American Chemical Society 2013 Nano letters Vol.13 No.3

<P>The hybrid structure of nanoparticle-decorated nanowires (NP@NW) combines the merits of large specific surface areas for NPs and anisotropic properties for NWs and is a desirable structure for applications including batteries, dye-sensitized solar cells, photoelectrochemical water splitting, and catalysis. Here, we report a novel <I>sol-flame</I> method to synthesize the NP@NW hybrid structure with two unique characteristics: (1) large loading of NPs per NW with the morphology of NP chains fanning radially from the NW core and (2) intimate contact between NPs and NWs. Both features are advantageous for the above applications that involve both surface reactions and charge transport processes. Moreover, the sol-flame method is simple and general, with which we have successfully decorated various NWs with binary/ternary metal oxide and even noble metal NPs. The unique aspects of the sol-flame method arise from the ultrafast heating rate and the high temperature of flame, which enables rapid solvent evaporation and combustion, and the combustion gaseous products blow out NPs as they nucleate, forming the NP chains around NWs.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2013/nalefd.2013.13.issue-3/nl300060b/production/images/medium/nl-2012-00060b_0002.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl300060b'>ACS Electronic Supporting Info</A></P>

Zero-valent iron for the abatement of arsenate and selenate from flowback water of hydraulic fracturing

Sun, Yuqing,Chen, Season S.,Tsang, Daniel C.W.,Graham, Nigel J.D.,Ok, Yong Sik,Feng, Yujie,Li, Xiang-Dong Elsevier 2017 CHEMOSPHERE - Vol.167 No.-

<P><B>Abstract</B></P> <P>Zero-valent iron (ZVI) was tested for the removal of 150 μg L<SUP>−1</SUP> As(V) and 350 μg L<SUP>−1</SUP> Se(VI) in high-salinity (ionic strength 0.35–4.10 M) flowback water of hydraulic fracturing. Over 90% As(V) and Se(VI) was removed by 2.5 g L<SUP>−1</SUP> ZVI in Day-14 flowback water up to 96-h reaction, with the remaining concentration below the maximum contaminant level for As(V) and criterion continuous concentration for Se(VI) recommended by US EPA. The kinetics of As(V) and Se(VI) removal followed a pseudo-second-order rate expression with the observed rates of 4.51 × 10<SUP>−2</SUP>–4.91 × 10<SUP>−1</SUP> and 3.48 × 10<SUP>−2</SUP>–6.58 × 10<SUP>−1</SUP> h<SUP>−1</SUP> (with 0.5–10 g L<SUP>−1</SUP> ZVI), respectively. The results showed that Se(VI) removal significantly decreased with increasing ionic strength, while As(V) removal showed little variation. Common competing anions (nitrate, bicarbonate, silicate, and phosphate), present in shallow groundwater and stormwater, caused marginal Se(VI) desorption (2.42 ± 0.13%) and undetectable As(V) desorption from ZVI. The competition between As(V) and Se(VI) for ZVI removal depended on the initial molar ratio and surface sites, which occurred when the Se(VI) concentration was higher than the As(V) concentration in this study. The characterization of As(V)- and Se(VI)-loaded ZVI by X-ray diffraction and Raman analysis revealed that ZVI gradually converted to magnetite/maghemite corrosion products with lepidocrocite in flowback water over 30 days. Similar corrosion compositions were confirmed in aerobic and anaerobic conditions regardless of the molar ratio of As(V) to Se(VI). The high reactivity and stability of ZVI showed its suitability for <I>in-situ</I> prevention of As(V) and Se(VI) migration due to accidental leakage, spillage, or overflow of flowback water.</P> <P><B>Highlights</B></P> <P> <UL> <LI> As(V) and Se(VI) in high-salinity flowback water was effectively removed by ZVI. </LI> <LI> As(V) removal was less susceptible to ionic strength variations than Se(V). </LI> <LI> Competing anions in groundwater and stormwater caused insignificant desorption. </LI> <LI> As(V) and Se(VI) competition depended on their molar ratio and ZVI surface sites. </LI> <LI> Surface characteristics of ZVI were unaffected by molar ratio and dissolved oxygen. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
