Abstract: A physiologically stable fluorophore includes a terminal moiety including a terminal reactive site that reacts with a reactive group of a substrate; a stability linker covalently bonded to the terminal moiety; and a bridge moiety covalently bonded to the stability linker such that the stability linker is interposed through chemical bonds between the bridge moiety and the terminal moiety; and a fluorescent moiety covalently bonded to the bridge moiety of the redox moiety and including: an electron bandgap mediator that is covalently bonded to the bridge moiety; a coordinate center covalently bonded to the electron bandgap mediator and that forms a Zwitterionic member with an atom in the electron bandgap mediator; and a steric hinder bonded to the electron bandgap mediator to provide steric hindrance for protection of the coordinate center.

Abstract: An object of the invention is to provide cellulose fibers which can give a cellulose composite that renders high transparency, a reduction in linear expansion coefficient, and a high modulus of elasticity possible. The invention relates to: a process for producing modified cellulose fibers which includes a modification reaction step of reacting cellulose with an aromatic compound in an organic acid to thereby modify the cellulose with an aromatic-ring-containing substituent; cellulose fibers modified with aromatic-ring-containing substituent; a dispersion of the cellulose fibers; and a cellulose fiber composite obtained from the same.

Abstract: The invention is a method for efficiently preparing alkali cellulose having a uniform alkali distribution therein. More specifically, the invention is a method for preparing alkali cellulose comprising steps of bringing pulp into continuous contact with an alkali metal hydroxide solution in a bucket conveyor type contactor to generate a contact mixture, and draining the contact mixture; a method for preparing a cellulose ether comprising use of the alkali cellulose thus prepared; and an apparatus for preparing alkali cellulose comprising a bucket conveyor contactor comprising at least one inlet port for introducing pulp and an alkali metal hydroxide solution at one end and at least one outlet port for discharging a contact mixture wherein the pulp and the alkali metal hydroxide solution can be moved from one end to the other end while bringing them into contact with each other to generate the contact mixture; and a drainer for separating a cake from the contact mixture discharged from the outlet port.
