A carbon microrod that holds a fine object by chemically adsorbing the object on the surface to make a dynamic measurement possible. An organic substance that leaves, after firing, glassy carbon that hardly becomes graphite, such as a chlorinated vinyl chloride resin, is mixed with a fine graphite powder having an average particle size of 1 &#x3bc;m, and the mixture is extrusion molded with a die having a diameter of 50 &#x3bc;m; the molded article is fired to give a carbon microrod comprising glassy carbon and crystalline carbon.

Carbon microrod and method of producing the same

An anti-stress agent for animals for reducing the growth inhibition or mortality of animals and a method of reducing stress using a feed composition having blended therein the anti-stress agent. The anti-stress agent for animals comprises one or more substances selected from L-ascorbic acid-2-phosphoric acid, a salt thereof and an L-ascorbic acid-2-glucoside, as an active ingredient, for inhibiting the increase of blood plasma lactate dehydrogenase (LDH), malate dehydrogenase (MDH) and aspartate aminotransferase (AspAT) and for inhibiting the increase of stress proteins in blood, which occur when animals are placed under stress. Also disclosed is a feed composition comprising the anti-stress agent, and a method of reducing the stress of animals by supplying the same as feed.

A carbon micro-sensor electrode is disclosed which is prepared by impregnating, adsorbing or chemically modifying a pure composite carbon wire having many micropores extending to its surface and interior with a reactant such as an enzyme, a metal complex compound, an organic compound or a metabolite; and a method for preparing this carbon micro-sensor electrode is also disclosed. The above-mentioned electrode can be used for a long period of time, since the reactant is received in the many micropores. Furthermore, after used, the electrode may be cut off to expose a new electrode surface, and this new electrode surface may be coated with a material which does not impede an electrode reaction, whereby the reactant can be prevented from flowing out. Thus, the carbon micro-sensor electrode of the present invention can be repeatedly utilized.

Carbon micro-sensor electrode and method for preparing it

A tapered carbon microelectrode is produced by extruding an organic material or a composition composed of crystalline carbon fine powder and an organic binder into a thin rod form, carbonizing said rod by calcining to produce a pure carbon thin rod, soaking the resulting thin rod as an anode in an electrolytic solution, gradually pulling up the thin rod while electrochemically oxidizing the tip portion of the thin rod. Then a lead wire is connected with the thick portion of the thin rod followed by coating all the surface except the conically sharp tip portion. The tapered carbon electrode can be used for various electrochemical measurements and scanning tunneling microscope.
