A major object of the present invention is to provide a method for producing induced pluripotent stem cells with low tumorigenesis potential and high induction efficiency. The invention provides a method for producing induced pluripotent stem cells comprising the step of introducing one or more nucleic acids that facilitate expression of at least one gene selected from the group consisting of NANOG, SOX2, OCT3/4, KLF4, LIN28, and c-MYC into somatic cells.

Method for producing induced pluripotent stem cells

The invention provides a plastic sorting method and apparatus, which, when plastic pieces comprising a plurality of types of resin plastics are agitated and frictionally charged, are able to impart the plastic pieces a necessary amount of charge or polarity for the thorough separation even if the difference in the amount of the different types of plastic pieces is large and to increase the recovery rate. If the amount of a specified type plastic pieces ( ) to be recovered is small, the agitation and the electrostatic separation is carried out after adding the specified type plastic pieces ( ) as auxiliary frictional charging material ( ) into the frictional charging device ( ), and the auxiliary frictional charging material ( ) remains in the frictional charging device ( ) and is used repeatedly.

Method and apparatus for separating plastic

A thermal decomposition apparatus for plastics wherein plastics are melted and thermally decomposed, and the resulting decomposition gas is cooled for condensation and recovered in the form of a thermal decomposition oil. The apparatus comprises a thermal decomposition reactor for melting and thermally decomposing the plastics therein, an extraneous matter discharge duct having one end opened in a melt of plastics within the reactor, an extraneous matter collecting container connected to the other end of the discharge duct, and an aspirator for aspirating extraneous matter within the reactor together with the melt through the discharge duct into the container.

Apparatus for thermally decomposing plastics and process for converting

A plate-shaped denitrating catalyst comprising a metal net, a finely divided porous carrier retained on the metal net with a binder and covering the metal net, and an active component supported on the carrier.

Process for repairing plate-shaped denitrating catalysts

A plate-shaped denitrating catalyst is produced by the steps of preparing a slurry from hydrated titania and a sol selected from the group consisting of silica sol, alumina sol and titania sol, firing the slurry to obtain a porous material, pulverizing the porous material to a powder, causing a metal net to support the powder thereon with a binder to form a plate-like piece, drying or firing the piece to obtain a porous carrier and depositing a catalytically active component on the carrier.

Process for producing plate-shaped denitrating catalyst

A highly active denitrating catalyst is produced by converting the surface layer of steel material to an aluminum alloy, treating the resulting steel material with an aluminum dissolving solution to dissolve out the aluminum and to render the surface layer porous, and immersing the steel material having the porous surface layer in a solution containing a vanadium compound to cause the porous surface layer to support the vanadium compound.

Process for producing highly active denitrating catalysts

A denitrating catalyst having a porous coating is produced by immersing a catalyst base of porous metal in a silica-containing coating bath, drying the catalyst base to form a carrier having a porour silica coating, immersing the carrier in a solution containing an active component and drying the resulting carrier to cause the carrier to support the active component thereon.
