  • Spin polarized tunneling study on spin Hall effect metals and topological insulator

    Spin orbit interactions give rise to interesting physics phenomena in solid state materials such as the spin Hall effect (SHE) and topological insulator surface states. Those effects have been extensively studied using various electrical detection methods. However, to date most experiments focus only on characterizing electrons near the Fermi surface, while spin-orbit interaction is expected to be energy dependent. Here we developed a tunneling spectroscopy technique to measure spin Hall materials and topological insulators under finite bias voltages. By electrically injecting spin polarized electrons into spin Hall metals or topological insulators using nonmagnetic material (NM) /oxide/ferromagnet (FM) junctions and measuring the induced transverse voltage, we are able to study SHE in typical 5d transition metals and the spin momentum locking in topological insulators. For spin Hall effect metals, the magnitude of the spin Hall angle has been a highly controversial topic in recent studies. Results obtained from various techniques (such as non-local spin valves, spin pumping and spin Hall torque) can differ by more than an order of magnitude. With the spin polarized tunneling experiment, we determined the spin Hall angles for heavy element metals (e.g., Ta, Pt, Ir and W). These results turned out to be consistent with the numbers obtained from spin Hall torque measurements, which can help to address this long debating issue. Besides the magnitude, the mechanism of the observed spin Hall effect (or spin orbit torques) is another issue that has attracted a lot of research interest. Competing mechanisms (intrinsic vs extrinsic, surface vs bulk origin) have been proposed to explain the observed phenomena. The voltage dependent spectra from our experiment provide useful information in distinguishing between those potential mechanisms. Finally, because of the impedance matching capability of tunnel junctions, the spin polarized tunneling technique can also be used as a powerful tool to measure resistive materials such as the various newly discovered and proposed topological insulators. In this talk, the results on the typical topological insulator bismuths selenide will be reported.

    5,10,15,20-Tetraferrocenyl porphyrin (PFc4) and coumarin-based thia-aza macrocycle ligand (L3) were studied for the development of cross-sensitive optical chemical sensors aimed to the determination of transition metal ions. The ligands oppositely vary their fluorimetric response: PFc4fluorescence is quenched upon the several transition metal ions concentration growth, while the fluorescence of L3 increases upon mercury ions exposure. By the simultaneous incorporation of both ligands in the same membrane, a series of cross-sensitive materials were obtained and tested for transition metal ions detection by CSPT method.

  • The characteristics and influencing factors analysis for heavy metals in vegetables Qingdao district

    Heavy metals can be absorbed from soils and atmospheric dust and accumulated by vegetables, and then ingested by human body through the food chains. They are very harmful to human health. Some statistic analysis experiments are executed by taking vegetables, soils from their roots and atmosphere dust in Qingdao district as research objects. First, this paper uses geochemistry method to analyze the heavy metals of vegetables. And then we adopt the Spearman related coefficient analysis method to analyze the relationships among the heavy metals in vegetables, soils from their roots and atmospheric dust. Analysis results show that rhizome vegetables have strongest capability in accumulating heavy metals from their soil. In contrast, fruit vegetables have weakest capability. Fruit vegetables, leaf vegetables and rhizome vegetables can cooperatively absorb heavy metals. Especially, rhizome vegetables do best. Besides, heavy metals in soils have promoting or inhibiting effect on fruit vegetables, leaf vegetables and rhizome vegetables. The heavy metals in atmosphere dust do not have obvious influence on leaf vegetables and rhizome vegetables, while have obvious influence on fruit vegetables. The results gotten from this paper can provide evidence to control city air pollution and to strengthen abatement of heavy metals pollution in soils.

  • Influence of pH value on availability of heavy metals in municipal sludge

    The availability of heavy metals in four kinds of sludge under the influence of different pH values are studied in the paper. According to the experiment results, the pH value has an important influence on the mobility and bioavailability of heavy metals in sludge. The lower the pH value of sludge is, the less heavy metals are absorped and the more they are released.

  • A new simultaneous method of Hall and magnetoresistance measurements at low and high magnetic field on liquid and amorphous metals, and semiconductors

    The Hall signals of Ga and Hg metals at liquid and solid states obtained through a new simultaneous method have been examined and compared with those of amorphous metals and solid state semiconductors of Si and InSb single crystals. Liquid metals of Hg and Ga of 5 N pure, para and ferromagnetic films of amorphous iron, and single crystals of Si and InSb were used as samples. Liquid metals were enclosed in the cell made of Macor or Pyrex glass, in which ditch is 200 and 400 /spl mu/m deep. The temperature was monitored and controlled within 0.5/spl deg/C by a thermocouple buried at the bottom of the cell. DC magnetic field of low field less than 0.3 Tesla is applied with a lab electromagnet, a superconductor magnet for high magnetic field up to 9 Tesla. Liquid metals such as Hg and Ga show the Hall effect and negligible magnetoresistance effect in the solid state, but the magnetoresistance effect in the liquid state appears much larger than in the solid state and badly affects the Hall effect.. It is also found that there is the magnetoresistance effect even in Si single crystal although the effect cannot normally be observed in low magnetic field less than 1 Tesla. For the ferromagnetic materials, the Hall signal is very much affected by the magnetoresistance.

  • Mechanism of the directed destruction of metals by cutting

    In the given article, on the basis of the standard hydrodynamic representations, the physical model of the directed destruction of metals by cutting is offered. Process of cutting of metals is considered as process of the directed destruction, i.e. process of deep plastic deformation of metal always led up to destruction on surfaces of the cutting, defined by process kinematics. The design of the metal-cutting tool for part removal liquid-alloy (in the form of a ridge) from an internal contact zone of shaving is presented. Physicomechanical properties of ridges both their geometrical form and the sizes testify that they are formed of a stream of the melted metal owing to fast cooling in environment. Identity of mechanical properties of ridges and the modified layer on a tool surface of shaving testify to identity of conditions of their formation from liquid metal. The experimental evidence of the offered physical model is produced.

  • Evaluation on soil heavy metals and organochlorine pesticides pollution in main grain producing area based on ArcGIS—A case study of Liaocheng

    With the rapid economic development, the soil environment has been polluted in varying degrees. The quality of the soil in the major grain producing areas affects the food safety and human health. Liaocheng City, the major grain producing areas in Shandong Province, covers an arable land of 70.01 × 104hm2. In order to investigate the heavy metals and organochlorine pesticides pollution institution, the farmland of Liaocheng had been divided into 136 units. One sampling point had been selected in each unit. Firstly, the location of sampling points had been ensured by GPS, and the surface soil of 136 sampling points had been collected. 10 kinds of pollutants had been monitored, which included As, Cd, Cr, Cu, Hg, Ni, Pb, Zn, DDTs and BHCs. Secondly, the single factor index had been used to evaluate the degree of soil pollution. The results showed that the polluted degrees of all heavy metals and organochlorine pesticides were different. The order of heavy metals pollution was Hg>;Cu>;Cd>;Zn>;Pb>;As>;Ni. The order of organochlorine pesticides pollution was DDTs>; BHCs. Thirdly, all different pollutants indexes had been inputted to ArcGIS. Based on the spatial analyst module in ArcGIS, Ordinary Kriging method had been used to finish the spatial interpolation of every kind of pollutants. At last, the spatial distribution maps of every kind of pollutants had been finished based on ArcGIS. The results showed that the pollution of the heavy metals and the organchlorine pesticides was not so heavily and had little influence upon the food production. By contrast, the soil pollution around the towns was more serious than that far from the towns. The most serious polluted area of the organchlorine pesticides located at Linqing county. Therefore, the areas surrounding all towns and the whole areas of Linqing county should be mainly protected.
