Pollution Buildup on Road Surfaces

Samples of sediment found on an urban road in Aberdeen (Scotland) were collected by washing designated surfaces. This method, called the “wet” method, was capable of collecting sediment of the smallest particle size range that is normally left behind by traditional sampling techniques using dry vacuuming. Over 17 months (mainly on a weekly basis), 66 samples were collected and analyzed for sediment loading, particle size distribution, concentration of heavy metals (Zn, Cu, Pb, Cd) in four sediment size fractions, and several dissolved pollutants in the effluent collected from washing (NO3?,?SO42?,?PO43?,?Cl?,?F?,?NH4+, total organic carbon, total carbon). Standard statistical methods, including multiple regressions, were used to determine relationships amongst different sediment characteristics. It was found that sediment loading, as well as concentrations of Cl? and SO42?, were highest in the winter months, especially when snow was present on the road surface. It was observed that 66% of total road sediment loading was found within a 0.5 m strip next to the curb. The average sediment particle sizes found were smaller than those previously recorded in the literature. As expected, the concentrations of heavy metals were highest in the smallest particle size fraction analyzed (<63?μm), and this occurred during the summer months when less sediment was available on the street surface. The antecedent dry weather period had a very weak and negative influence on the loading rate of the smallest particle size fraction next to the curb.     

Resonant charge transfer in back-scattering of H-atoms from the Cs adsorbates on the Cs/Cu(1 1 1) surface

We use the wave packet propagation approach to study the dynamics of resonant charge transfer in hydrogen back-scattering from Cs adsorbates on Cu(1 1 1). The affinity level of the projectile strongly interacts with an adsorbate-localized state leading to an important modification of the projectile–substrate resonant charge transfer. At very low collision energies (<2.5 eV) the adiabatic evolution of the system leads to the blocking of the negative ion formation in back-scattering of neutral hydrogen atoms from Cs adsorbate. At higher energies non-adiabatic transitions exist, and negative ion formation is possible.

铝的低价硫化物歧化反应的应用研究

对用低价硫化铝的歧化反应在镀铝膜和富集催化剂中贵金属作了研究。用蒸发源(4Al Al2S3)进行反应蒸发镀膜,系统真空度为5Pa左右,温度为1100℃。所得镀层表面光滑、平整,扩散层厚。镀膜层为Fe3Al及AlFe两相,镀膜时,基体温度应大于800℃。用该种方法富集催化剂中贵金属时,试验表明,在温度1200～1400℃、真空度大于666.7Pa下,反应蒸馏3h,可使氧化铝还原20%左右,贵金属富集1.2倍;相同条件下蒸馏四次,可使贵金属富集1.6倍,收率大于92%,实验中得到表面严重氧化的细小铝颗粒,该问题的解决有待进一步的研究。
