摘要： Provided is a method of oxidizing a substrate with excellent oxidizing power to yield a corresponding oxide. The method can employ a commercially available imide compound as intact as a catalyst and can produce the oxide in a high yield under mild conditions.A method for producing an oxide according to the present invention includes performing oxidation of a substrate in the presence of oxygen and ozone under catalysis of an imide compound to yield a corresponding oxide. The imide compound has a cyclic imide skeleton represented by Formula (I). In the formula, n is selected from 0 and 1; and X is selected from an oxygen atom and an —OR group, where R is selected from hydrogen and a hydroxy-protecting group.

摘要： A needleless injector pressurizes a substance to be injected having an ejection pressure defined as a pressure of the substance to be injected ejected through an ejection port. The ejection pressure is raised to a first peak pressure after pressurizing is started, is lowered to a pressure lower than the first peak pressure afterward, and then is raised to a second peak pressure again. An on-completion reached depth that is an on-completion reached depth of the substance when the pressurizing portion completes pressurizing is adjustable, the on-completion reached depth being increased along with increase of the first peak pressure and being increased along with reduction of a length between peaks from a first timing at which the ejection pressure reaches the first peak pressure to a second timing at which the ejection pressure reaches the second peak pressure.

摘要： A needleless injector configured to inject an injection intended substance to an injection target region, by injecting the injection intended substance includes a nozzle portion and a pressing portion, and a predetermined gap is formed between the nozzle portion and the pressing portion. The nozzle portion is formed to have a portion of the distal end portion that comes into contact with the injection target region and has a width (a) falling within a range from 3.5 mm to 5.5 mm, and a ratio (b/a) defined by an inner diameter (b) of a portion of a distal end portion of the pressing portion that comes into contact with the injection target region by the width (a) falls within a range from 1.5 to 5.0. A part of the injection target region is received in the predetermined gap when the pressing portion presses the injection target region.

摘要： A carbon dioxide separation membrane according to the present invention includes: an ionic liquid affinitive porous layer (C) having an ionic liquid-containing liquid (A) retained in voids; and an ionic liquid non-affinitive porous layer (B). The ionic liquid affinitive porous layer (C) may contain inorganic materials (for example, metal oxide particles having an average particle size of about 0.001 to 5 μm on a number basis). An average thickness of the ionic liquid affinitive porous layer (C) may be about from 0.01 to 10 μm. The ionic liquid affinitive porous layer (C) may include the ionic liquid-containing liquid (A) at a ratio from 0.1 to 99 parts by volume with respect to 100 parts by volume of voids. It may be a carbon dioxide separation membrane for fertilizing plants with carbon dioxide. The carbon dioxide separation membrane can reduce a size of the carbon dioxide concentrating device and enables smooth operation of the device.

摘要： This ionic liquid-containing laminate includes a porous layer having affinity with ionic liquids (C), said layer holding an ionic liquid-containing liquid (A) within voids therein, and a porous layer lacking affinity with ionic liquids (B). The porous layer having affinity with ionic liquids (C) may include an inorganic material (e.g., metal oxide particles having an average particle size of 0.001 to 10 μm on a number basis). The ionic liquid-containing liquid (A) may include an ionic liquid containing cations selected from ammonium, imidazolium and phosphonium cations, and anions selected from fluorine-containing anions, cyano-containing anions and amino acid-derived anions. The porous layer having affinity with ionic liquids (C) may include 1 to 100 volume parts of the ionic liquid-containing liquid (A) with respect to 100 volume parts of voids therein. The ionic liquid-containing laminate is easily formable, and is able to stably hold (or fix) the ionic liquid while maintaining said liquid in a liquid state.

摘要： The adapter includes a housing and a filling nozzle provided in communication with a containing portion in the housing and coming into contact with an end surface of the injection device, in which the injection port of the injection nozzle is formed, when the housing is attached to the injection device. An open end of the filling nozzle is set to be smaller than an inner diameter of the containing portion and larger than the injection port. Of an internal space of the housing from a partial region of the containing portion to the open end, at least a predetermined space being continuous and including the partial region is formed in a manner where an inner diameter of the predetermined space decreases toward a side of the open end. According to this configuration, the injection fluid can be suitably transferred from the outside to a needleless injector.
