Abstract:
A method for synthesizing carbon nanocoils with high efficiency, by determining the structure of carbon nuclei that have been attached to the ends of carbon nanocoils and thus specifying a true catalyst for synthesizing carbon nanocoils is implemented. The catalyst for synthesizing carbon nanocoils according to the present invention is a carbide catalyst that contains at least elements (a transition metal element, In, C) or (a transition metal element, Sn, C), and in particular, it is preferable for the transition metal element to be Fe, Co or Ni. In addition to this carbide catalyst, a metal catalyst of (Fe, Al, Sn) and (Fe, Cr, Sn) are effective. From among these, catalysts such as Fe 3 InC 0.5 , Fe 3 InC 0.5 Snw and Fe 3 SnC are particularly preferable. The wire diameter and the coil diameter can be controlled by using a catalyst where any of these catalysts is carried by a porous carrier.
Abstract:
The present invention provides a sensor including a detection unit having a detection electrode and a polymer layer that is disposed on the detection electrode and includes a mold having a three-dimensional structure complementary to a steric structure of a microorganism to be detected. The sensor detects the microorganism based on a state of capturing the microorganism in the mold. The polymer layer is formed by a manufacturing method including: a polymerization step of polymerizing a monomer in the presence of the microorganism to be detected, to form the polymer layer having captured the microorganism on the detection electrode; a destruction step of partially destroying the microorganism captured in the polymer layer; and a peroxidation step of peroxidizing the polymer layer to release the microorganism from the polymer layer.

Abstract:
A seedling-cutting apparatus includes a pair of arms (211, 212) that is to nip a portion of a stem of a seedling for grafting and that can be opened and closed and a blade (111) that is provided so as to be capable of reciprocating relative to the portion of the stem. At least one of the pair of arms (211, 212) includes a through hole (210) or a cutout that penetrates a portion of the arms (211, 212) along a direction in which the blade reciprocates. At least a portion of the through hole (210) or the cutout faces the portion of the stem and at least a portion of the blade (111) moves through the through hole or the cutout.
Abstract:
Provided is an oxidation reactor capable of oxidizing hydrocarbons with both reaction efficiency and energy efficiency. The oxidation reactor according to the present invention includes a liquid inlet channel, a gas inlet channel, a gas-liquid mixing unit, and a flow reactor. Through the liquid inlet channel, a liquid containing a reaction substrate hydrocarbon is introduced. Through the gas inlet channel, a gas containing oxygen and ozone is introduced. The gas-liquid mixing unit mixes the liquid introduced from the liquid inlet channel with the gas introduced from the gas inlet channel. In the flow reactor, an oxidation catalyst is immobilized or packed. The gas-liquid mixing unit houses, in its channel, a mobile particle which is capable of rotating and/or moving to mix the liquid with the gas to thereby form a gas-liquid slug flow. The gas-liquid slug flow is introduced into the flow reactor.

Abstract:
The present invention is a sensor for detecting a microorganism, which is provided with a detection unit (17) equipped with a detection electrode (11) and a polymer layer (14), wherein the polymer layer (14) is arranged on the detection electrode and is provided with a template having a three-dimensional structure complementary to a three-dimensional structure of a microorganism (13) to be detected. The sensor detects a microorganism on the basis of the captured state of the microorganism onto the template (15). The polymer layer (14) is formed by a manufacturing method including a polymerization step (St1) of polymerizing a monomer in the presence of the microorganism (13) to be detected to form a polymer layer (14) having the microorganism (13) incorporated therein on the detection electrode, and a disruption step (St2) of bringing at least a part of the microorganism (13) incorporated in the polymer layer (14) into contact with a solution containing a lytic enzyme to disrupt the microorganism.
