Abstract: Surface water was taken from river mouth to the central area of Meiliang Bay, Taihu Lake, a large shallow eutrophic lake in China. Suspended solids were condensed by centrifugation 25 L surface water samples from each selected site. Suspended solids and surface sediments were further freeze-dried and microwave digested before determining the metals by ICP-AES. Among the metals analyzed in suspended solids and sediments, contents of Cr, Cu, Mn, Ni, and Zn in suspended solids were significantly higher than those in sediments while contents of Al, Ba, Be, Ca, Co, Fe, K, Mg, Pb, and V in suspended solids were 10%-30% higher than those in sediments. Sr and Ti contents in suspended solids and sediments were very similar. Na content in suspended solids was lower than that in sediments. Heavy metals were significantly accumulated in suspended solids. From the river mouth to the center of Meiliang Bay,contents of Cr, Cu, Pb, and Zn in suspended solids showed a gradual decreasing trend indicating the river(Zhihugang River) still discharged large quantity of heavy metalsto Meiliang Bay. The study suggests that the geochemical behaviors and ecological effects of heavy metals in suspended solids may serve as a good indicator for the pollution of lake.

Abstract: Phellinus mori had rich extracellular enzymes. The amylase activity in liquid culture of the fungus had the maximum value on day 7. Pectinase showed two peaks on day 9 and 12, respectively. The maximum value of carboxymethyl cellulose enzyme (CMCase) activity appeared on day 10. The laccase reached its peak on day 9. It was indicated that Phellinus mori preferred starch to pectin, cellulose and lignin. The protein concentration had two peaks on day 8 and 11, respectively. The reducing sugar concentration decreased gradually with the incubation time, and the pH value decreased on days 2-7 but increased after day 8.

Abstract: 针对被典型化学品双酚A(BPA)与邻苯二甲酸二乙酯(DEP)污染原水的应急处理工艺进行了研究.结果表明,活性炭吸附可有效去除双酚A和DEP.拟二级动力学模型和Elovich模型较好地描述粉末活性炭对原水中BPA和DEP的吸附过程.中试条件下,50 mg/L的粉末活性炭可分别将原水中浓度约为500 μg/L的双酚A和3.3 mg/L的DEP处理达标.炭砂滤柱对2种化学品的动态吸附表明,BPA和DEP的去除率受它们初始浓度的影响较小,在滤速为5.1~15.3 m/h的范围内BPA和DEP的去除率基本不受滤速的影响.当同时采用粉末活性炭和炭砂滤柱工艺时, PAC的吸附过程是去除污染的主要阶段,炭砂滤柱可以作为粉末活性炭的有效补充保证一定的安全系数.KMnO4和Cl2均不能氧化DEP,3 mg/L的KMnO4和1.5 mg/L的Cl2可几乎完全氧化水中浓度为850 μg/L的BPA,BPA的氯化产物和KMnO4的氧化产物及其毒性有待于进一步研究. 1.5 mg/L高锰酸钾和PAC联用对去除DEP无协同作用,对去除BPA有促进作用.

Possible quantum phase-manipulation of a two-leg ladder in mixed-dimensional fermionic cold atoms
Wen-Min Huang,Kyle Irwin,Shan-Wen Tsai
Physics , 2013, DOI: 10.1103/PhysRevA.87.031603
Abstract: The recent realization of mixed-dimensional systems of cold atoms has attracted much attention from both experimentalists and theorists. Different effective interactions and novel correlated quantum many-body phases may be engineered in these systems, with the different phases being tunable via external parameters. In this article we investigate a two-species Fermi atom mixture: one species of atom exists in two hyperfine states and is confined to move in a two-leg ladder, interacting with an on-site interaction, and the other moves freely in a two dimensional square lattice that contains the two-leg ladder. The two species of atoms interact via an on-site interaction on the ladder. In the limit of weak inter-species interactions, the two-dimensional gas can be integrated out, leading to an effective long-range mediated interaction in the ladder, generated by to the on-site inter-species interaction. We show that the form of the mediated interaction can be controlled by the density of the two-dimensional gas and that it enhances the charge density wave instability in the two-leg ladder after the renormalization group transformation. Parameterizing the phase diagram with various experimentally controllable quantities, we discuss the possible tuning of the macroscopic quantum many-body phases of the two-leg ladder in this mixed-dimensional fermionic cold atom system.
Andreev bound states in iron pnictide superconductors
Wen-Min Huang,Hsiu-Hau Lin
Physics , 2009, DOI: 10.1103/PhysRevB.81.052504
Abstract: Recently, Andreev bound states in iron pnictide have been proposed as an experimental probe to detect the relative minus sign in the $s_\pm$-wave pairing. While previous theoretical investigations demonstrated the feasibility of the approach, the local density of states in the midgap regime is small, making the detection hard in experiments. We revisit this important problem from the Bogoliubov-de Gennes Hamiltonian on the square lattice with appropriate boundary conditions. Significant spectral weights in the midgap regime are spotted, leading to easy detection of the Andreev bound states in experiments. Peaks in the momentum-resolved local density of states appear and lead to enhanced quasiparticle interferences at specific momenta. We analyze the locations of these magic spots and propose they can be verified in experiments by the Fourier-transformed scanning tunneling spectroscopy.
