A home-made LVDT displacement-measuring system was developed and applied to study the process of deformation on NiO during early stage of molten carbonate fuel cell (MCFC) operation. A series of in situ deformation tests was performed at a normal temperature (923 K) with porous Ni and NiO plaques under the atmospheres and load conditions in the presence of carbonate electrolyte. The results indicated that the most significant deformation took place when Ni plaque underwent both in situ oxidized and lithiated processes under a load condition, in particular, the deformation of Ni plaque occurred more severely at the beginning of processes.

The paper focuses on location of seal imprints on Chinese bank-checks based on region growing. Region growing method can be applied to searching and locating connection region in an image. A seal imprint, however, is generally composed of various connection regions which are unconnected to each other. In order to locate the seal imprint, these connection regions must be fused together. In the paper, an algorithm for locating seal imprints on Chinese bankchecks based on region growing is proposed, of which a fusion criterion for connection regions in a seal imprint is put forth based on the image feature of Chinese bankcheck, and a center-rays model is proposed to find the topological relationship between connection regions, for which externally-tangent rectangle of region is used as the mark of location of region. The location experiment is achieved with a false-acceptance rate of 7.1% and a false-rejection rate of 0% on Chinese bankcheck.

In the title coordination polymer, [Cu(NCS)2(C12H8N2)]n, the CuII atom is situated on a twofold rotation axis and is coordinated by two N atoms from the bidentate 1,10-phenanthroline ligand and four thio­cyanate groups to confer a CuN4S2 octa­hedral geometry and resulting in a layer structure extending parallel to (100).

In the title coordination polymer, [Zn(C8H4O4)(C14H14N4)]n, the ZnII atom is coordinated by two N atoms from two 1,2-bis­(imidazol-1-ylmeth­yl)benzene ligands as well as by the two O atoms from two terephthalate ligands, confering a tetra­hedral coordination geometry. The bridging ligands generate a three-dimensional structure.
