Abstract: A polymer carrier to which a prescribed zinc complex group is binding directly or through a spacer, having property to bond, under a certain condition, to an anionic substituent (a phosphate group, for example), showing low solubility to a solvent (preferably insolubility to a solvent) as a whole, and being capable of capturing, separating and purifying easily a substance having an anionic substituent (a phosphate group, for example).

Abstract: The present invention provides an electrolyte composition that can simultaneously realize solidification of the electrolyte layer and alleviation of a reduction in photoelectric conversion rate caused by the solidification of electrolyte layers, and a dye-sensitized solar cell having a solid electrolyte layer comprising the electrolyte composition. The electrolyte composition includes nanoparticles with an ammonium group or a nitrogen-containing heterocyclic group bound thereto; or a porous inorganic film with an ammonium group or a nitrogen-containing heterocyclic group bound thereto. The nanoparticles and the porous inorganic film each are formed of a metal oxide. The nitrogen-containing heterocyclic group is an imidazolium group, a pyridinium group, a triazolium group or a guanidinium group, and the counter anion group is F?, Cl?, Br?, I? or the like. The ammonium group or the nitrogen-containing heterocyclic group chemically modifies the nanoparticles or the porous inorganic film.

Abstract: A joist suitable for use in a composite concrete floor is disclosed. The joist comprises a top chord, a bottom chord; and a vertically extending intermediate web having a top end secured to the top chord and a bottom end secured to the bottom chord. The top chord comprises a pair of longitudinally continuous symmetrical chord members facing each other and embracing the top end of the web. Each of the chord members includes a vertical portion secured to the top end of the web and a slanting upper extension extending above and away from the top end of the web, thereby providing a shear connecting portion and a flared opening, between the two facing chord members, giving access to the web and improving access of a welding tool to the area between the symmetrical portion of the top chord and the web member that must be joined together.

Abstract: The present invention concerns a framing system for a composite concrete floor, the framing system comprising horizontally extending primary framing members supporting secondary framing members across the primary framing members. Each of the secondary framing members has two opposite ends provided with a shear shoe fixed to the primary framing members by means of a structural joint sufficient to provide a shear connection between the concrete floor and the primary framing members. Thanks to these shear shoes, the framing system of the invention has an increased resistance to horizontal shear forces as compared to prior art concrete floor systems.

Abstract: A structural post is disclosed for use in a van of the type comprising an outer shell with vertical sidewalls and an interior wall surface comprising a plurality of liner panels.
