Formation and characterization of phthalocyanine dimer/C60 solar cells

Ni-Cu-Zn ferrite/CaTiO_3 and Ni-Cu-Zn ferrite/BaTiO_3 composites which can be applied in low temperature co-fired ceramic(LTCC) technology were synthesized by conventional solid-state reaction at temperature lower than 950℃.Influence of the microstructures and the gap parameterδ/D on the complex permeability of the above two composites was investigated.The modifiedδ/D values of the above two composites show a good fit to the magnetic circuit model.The dielectric properties of the composites were predicte...     

Exploitation of shape memory alloy actuator using resistance feedback control and its development

The relationship between phase transformation and electric re sistivity of Ti-42.6Ni-7Cu SMA was investigated. In the isothermal tensile tests, stress—strain curve shows large hysteresis and nonlinearity, whereas the resistivity—strain curve can be fitted by linearity. The resistivity of SMAs can be determined from the volume fractions of the martensitic and austenitic phas es. This characteristics leads to that the resistance of the SMAs is used as a parameter of strain of SMAs. A SMA actuator using resistance feedback control system was proposed, which can control and retain positioning at any positions without using sensor devices, and the deviation of position of this system was less than 3 μm.     

生活垃圾焚烧飞灰中的二恶英检测

讨论了垃圾焚烧飞灰中二恶英检测的预处理流程和检测方法 .在此基础上 ,采用日本的“废物处理过程中二恶英标准测试方法” ,以上海浦东生活垃圾焚烧发电厂飞灰为对象 ,检测其中二恶英质量浓度 .结果为 6次取样 (飞灰 )中的二恶英质量浓度实测值为 4 2～ 2 4 8ng·g-1,相应毒性当量为 0 .98～ 4 .4 0ng·g-1.参照日本填埋场废物进场要求 ,基本可以填埋处置 .
