    Abstract: A method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver hybrid on transparent substrate is provided. Transparent substrate with oxidant coating containing silver salt is immersed into 3,4-ethylenedioxythiophene (EDOT) solution. The oxidant turns EDOT monomer to poly(3,4-ethylenedioxythiophene) (PEDOT) coating on the transparent substrate; meanwhile, the silver salt itself is reduced to nano silver by the EDOT monomer, resulting in a nano silver-doped PEDOT coating. Thereby, a transparent conductive film made of PEDOT/nano silver coating on transparent substrate is obtained. The transparent conductive film with PEDOT/nano silver coating prepared in the present invention possesses the advantages of high electrical conductivity, optical transparency and environmental stability.

    Abstract: A stiffness-controllable earthquake-isolation support using negative gravity stiffness, which comprises an upper plate connected to an upper structure, a lower plate connected to a base structure at the bottom, K supporting columns arranged longitudinally between the upper and lower plates, with the supporting columns respectively connected with the upper and lower plates through a ball hinge, and L elastic connecting plates arranged laterally between the supporting columns, wherein K≧3, L≧N×K and N≧1. The earthquake-isolation support, the supporting column and the ball hinges at both ends of the supporting column form, under the action of gravity of the upper structure, the negative gravity stiffness that causes the upper structure to deviate from the equilibrium position, and the frame structure restores the upper structure to the equilibrium position, with the stiffness of the earthquake-isolation support adjustable.

    Abstract: An I-shaped steel with discontinuous top flange reinforced compound concrete beam containing demolished concrete lumps and a construction process thereof. The beam comprises an I-shaped steel having discontinuous top flange, longitudinal bars (7), stirrups (6), waist bars (8), fresh concrete (5), and demolished concrete lumps (4). The I-shaped steel having discontinuous top flange consists of a bottom flange plate (3), a web (2) and a discontinuous top flange plate (I). The discontinuous top flange plate (1) consists of two rectangle steel plates or trapezoid steel plates located at both sides of the I-shaped steel. The two steel plates have a same length that is one third of a length of the I-shaped steel. The trapezoid steel plate has a width of a short side no less than a quarter of a width of the long side. The recycled compound concrete beam saves steel, fully uses the demolished concrete lumps, and is convenient to construct.

    Abstract: The invention presents a LTCC balun filter using two out-of-phase filtering circuits. The LTCC balun filter is comprised of three half-wavelength resonators and grounds which are located on fourteen metal layers. Vias are utilized to connect different metal parts. The first, fourth, seventh, eleventh and fourteenth metal layers are the ground. The three half-wavelength resonators are on the second, third, fifth, sixth, eighth, ninth, tenth, twelfth and thirteenth metal layers. By adjusting the coupling parts of the three half-wavelength resonators, namely the lengths of the seventh, eighth, ninth, tenth and eleventh layers, as well as the distances between them, the coupling strength between the half-wavelength resonators can be tuned. In addition, the quality factor of the circuit can be improved by tuning the port positions. By using the multi-layer LTCC technology, the present invention has the advantage of compact size, novelty, creativity and practicability.
