| 7 | ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY STUDY OF CORROSION INHIBITION OF MODIFIED LIGNOSULPHONATE FOR CARBON STEEL显示文摘The corrosion inhibition for carbon steel in circulating cooling water by modified lignosulphonate has been investigated using electrochemical impedance spectroscopy technique. Results show that the inhibition efficiency of modified lignosulphonate GCL2 is a great improvement on that of lignosulphonate. The maximum inhibition efficiency of GCL2 reaches 99.21% at the concentration of 400mg·L-1 at 303K. The corrosion inhibition of GCL2 is attributed to forming adsorption film on the metal surface for the electrochemical impedance spectroscopy in GCL2 solution shows more than one time-constant. Moreover, results also indicate that it is more efficient in stirring solution than in still solution for GCL2 because the constant of adsorption in stirring solution is much larger than that in still solution. The adsorption of inhibitor GCL2 follows Langmuir’s adsorption isotherm. | C.H. Yi X. Q. Qiu D.J. Yang H.M. Lou | 2005 | Acta Metallurgica Sinica(English Letters)2005,18,4: | 6 |
| 8 | Transition metal oxides as hole-transporting materials in organic semiconductor and hybrid perovskite based solar cells显示文摘Organic polymer solar cells(OSCs) and organic-inorganic hybrid perovskite solar cells(PSCs) have achieved notable progress over the past several years.A central topic in these fields is exploring electronically efficient,stable and effective hole-transporting layer(HTL) materials.The goal is to enhance hole-collection ability,reduce charge recombination,increase built-in voltage,and hence improve the performance as well as the device stability.Transition metal oxides(TMOs) semiconductors such as NiO_x,CuO_x,CrO_x,MoO_x,WO_3,and V_2O_5,have been widely used as HTLs in OSCs.These TMOs are naturally adopted into PSC as HTLs and shows their importance.There are similarities,and also differences in applying TMOs in these two types of main solution processed solar cells.This concise review is on the recent developments of transition metal oxide HTL in OSCs and PSCs.The paper starts from the discussion of the cation valence and electronic structure of the transition metal oxide materials,followed by analyzing the structure-property relationships of these HTLs,which we attempt to give a systematic introduction about the influences of their cation valence,electronic structure,work function and film property on device performance. | Pingli Qin Qin He Dan Ouyang Guojia Fang Wallace C.H.

| 14 | NEW ACHIEVEMENTS ON THE THEORY AND TECHNOLOGY OF EXPLOSIVE WELDING显示文摘There are four new achievements of this work on the theory and technology of explosive welding.(1) It has been found and defined three kinds of bonding interfaces: big wavy, small wavy and micro wavy, and the micro wavy interface is the best. In a cladding plate,it is for the first time to find that the form of interface presents regular distribution.(2) Although the interface has the features of melt, diffusion and pressure welding in the mean time, the seam and 'hole' brought by the melt weaken the bonding strength of interface greatly, and the effect of melt on interface must be eliminated in explosive welding, so explosive welding is not a melt weld. The diffusion welding is a kind of form of pressure welding, and the diffusion is not the reason of the bonding of interface but the result of interface high pressure. So the diffusion welding cannot also explain the bonding mechanism of it. The experiment and theory make clear that explosive welding is a special pressure one.(3) To get good interface of no melt, explosive charge must be selected on the low limit of welding windows. In explosive welding, the drive plate should be treated as the viscous and plastoelastic body, not incompressible fluid. The bending moment under the explosive welding loading must be greater than that under dynamic limit of drive plate. According to the condition, the lower limit of explosive welding is obtained. It is about 20% less than that obtained by tradition calculation, and suitable for engineering application.(4) It is for the first time to test and study on soil anvil characteristics and change regularity under explosive welding impact loading. Through soil anvil parameter optimization analysis, it is the best for explosive welding with sandy soil of water content 17.00% and density 1.74g/cm3. | C.G. Shi, Y.H. Wang, L.G. Cai and C.H.
