摘要:
The present invention relates to a cooling/heating method comprising the application and removal of a pressurising gas on a hybrid organic-inorganic porous material (MOF) whereby a breathing transition is produced, in which a change in volume in the structure of the compound occurs when its pores open/close, together with adsorption/desorption of a gas after applying and removing a pressurising gas on the compound; breathing which occurs at temperatures close to ambient temperature (from -20°C to 60°C) and at low pressures (from 10-5 bar up to 50 bar) and with great isothermal entropy changes (> 100 J K-1 kg-1). The invention also relates to a cooling/heating device comprising the hybrid materials defined above.

Problem to be Solved An agent for ameliorating chronic kidney disease which is not an existing symptomatic therapeutic drug for chronic kidney disease, and which can increase the eGFR value and can improve renal function per se is provided. Solution An agent for ameliorating and/or preventing chronic kidney disease containing 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt thereof as an active ingredient is prepared. Preferably, a metal-containing compound such as sodium ferrous citrate is contained in these ALAs. As the above-mentioned ALAs, ALA; various esters such as ALA methylester, ALA ethylester, ALA propylester, ALA butylester, and ALA pentylester; and hydrochlorides, phosphates, and sulfates, and the like of these ALA esters can be preferably exemplified.

The present invention relates to a chemical deposition raw material including a heterogeneous polynuclear complex in which a cyclopentadienyl and a carbonyl are coordinated to a first transition metal and a second transition metal as central metals, the chemical deposition raw material being represented by the following formula. In the following formula, the first transition metal (M 1 ) and the second transition metal (M 2 ) are mutually different. The number of cyclopentadienyls (L) is 1 or more and 2 or less, and to the cyclopentadienyl is coordinated one of a hydrogen atom and an alkyl group with a carbon number of 1 or more and 5 or less as each of substituents R 1 to R 5 . With the chemical deposition raw material of the present invention, a composite metal thin film or a composite metal compound thin film containing plural metals can be formed from a single raw material.
