Abstract:
본 발명은 고가이면서 제강이 용이하지 않은 희토류 원소를 포함하지 않으면서도, 내산화성과 전기전도성이 높고 동시에 고온에서 크롬(Cr)의 휘발속도가 낮아, 특히 연료전지용 연결재에 적합한 스테인리스강에 관한 것이다. 본 발명에 따른 스테인리스강은, Cr: 20중량% 초과 ~ 35중량%, Mn: 1중량% 이하, Nb: 0.3중량% ~ 5중량%를 함유하고, 나머지 Fe와 불가피한 불순물로 이루어진 것을 특징으로 한다.
Abstract:
A method of regulating mammalian target-of-rapamycin(mTOR) activity based on mTOR control mechanism by phospholipase D(PLD) AND Rheb(Ras homolog enriched in brain) is provided to cure mTOR-related metabolic disease through the mTOR suppression. A method of regulating mammalian target-of-rapamycin(mTOR) activity comprises (i) coupling Rheb and mTOR through PLD2 by interaction between phospholipase D 2(PLD2) and Rheb; (ii) increasing the concentration of PA by moving phosphatidic acid(PA) produced from PLD2 to adjacent mTOR; and (iii) increasing mTOR kinase activity by coupling Rheb with mTOR through the increase of PA density around the adjacent mTOR.
Abstract:
A method for controlling the activity of mTOR(mammalian target-of-rapamycin) with the interaction of phospholipase D(PLD) and raptor is provided to cure metabolic diseases related with mTOR by controlling mTOR through the control of the PLD activity. A method for controlling the activity of mTOR(mammalian target-of-rapamycin) is to suppress PLD2 through raptor and mTOR complex(PLD/raptor/mTOR complex) by suppressing the interaction of PLD2 and raptor. Suppressing the formation of the PLD/raptor/mTOR complex is performed by inactivating a raptor binding domain of PLD2 or a PLD2 binding domain of raptor.
Abstract:
PURPOSE: Ferritic stainless steel for solid oxide fuel cells and a connecting member using the same are provided to enable mass production at low cost since rare-earth elements are not used. CONSTITUTION: Ferritic stainless steel for solid oxide fuel cells consists of Cr of 20~35weight%, Mn of 1weight% or less, Nb of 0.3~5weight% and Fe and inevitable impurities. Alternatively, the content of the Nb is 0.8~1.5weight%. The territic stainless steel further comprises C of 0.03weight% or less, N of 0.03weight% or less, Mo of 5.0weight% or less, Cu of 3.0weight% or less, one or more of Ti, V and Zr of 0.5weight% or less, and one or more of Si, Ti, Al, Mg and Ca of 0.1weight% or less.
