The structure, crystallization kinetics and magnetic property of as-quenched Fe_(73.5)si_(13.5)B_9Nb_3Cu_1 amorphous ribbon(R0) as well as ribbons after autoclave treatment at 100°C and 150°C(R1 and R2) have been systematically studied by various techniques. With increasing autoclave treatment temperature,the measured structural, kinetic and magnetic parameters of samples increase firstly, i.e. R0 se or recover to the as-quenched sample, i.e. R2 se results indicate that the sROs in R1 samples increased by transforming from fcc to bcc structure during the autoclave treatment and that the autoclave treatment can decrease the large radius(r_M) MRO(medium range order),but increase the small rMMRO. The measured structural, thermal and magnetic parameters of R2 sample have a tendency to recover toward as-quenched R0 sample. The thermal and magnetic parameters of samples after solely annealing treatment at higher temperature have no obvious recover *** uneven actions of pressure and temperature in autoclave treatment may be helpful for us to search a new method to improve the magnetic properties of Fe-based glasses.

重访南丝绸之路西线第一站:成都-邛崃-雅安关于南丝绸之路的起点,一直有两种说法,一种说法是南丝绸之路的起点在成都,而另一种说法是南丝绸之路的起点在邛崃,起点在成都的说法认同者居多,尽管如此,这样的比较似乎也从一个侧面反映出邛崃小城曾经的繁荣,同时,也折射出它不输于成都的优雅和成熟。公元前311年,蜀国守张若筑临邛县城,周6里,高5丈,与成都、郫县、巴县同为四川最早筑成的4座城池,自此,天府南来第一州伴烟雨而生,成为南丝绸之路上最具诗意的小城。无论是南丝绸之路起始于成都或是起于邛崃,都注定与一位古代传奇的男子有着千丝万缕的联系,他

李商隐曾经在他最为著名的那首无题诗中这样写道:庄生晓梦迷蝴蝶,望帝春心托杜鹃。他用这样的诗句来追忆逝水年华,忆起那些如同一场美梦一般的岁月,在诗人的心中,那片对于"春心"的怀念如同亡国的君主将感伤之情都寄托于杜鹃鸟的凄断声一般,而由于读音相似,人们也总将这伤春之情寄托在杜鹃花的身上。其实,这样的情怀固然诗意,却不免偏狭,春天是一种心情,一种情怀,它可

One-step harvest of high-purity methane(CH_(4))from ternary propane/ethane/methane(C_(3)H_(8)/C_(2)H_(6)/CH_(4))mixtures remains a desirable yet challenging goal for natural gas ***,adsorbents either suffer from high capacity and selectivity,or are caught in a dilemma of scalable ***,we demonstrate a scalable pillar layered metal-organic framework Ni-MOF for highly efficient one-step CH_(4)***-MOF exhibits high C_(2)H_(6)and C_(3)H_(8)uptakes of 83.3 and 86.1 cm^(3)/g at 298 K and 100 kPa and remarkable C_(2)H_(6)/CH_(4)(50/50,volume ratio,21.5)and C_(3)H_(8)/CH_(4)(50/50,volume ratio,212.0)***,high C_(2)H_(6)(42.2 cm^(3)/g at 10 kPa)and C_(3)H_(8)(64.7 cm^(3)/g at 5 kPa)capacities in the low-pressure region at 298 K were realized on Ni-MOF,suggesting the strong affinities of Ni-MOF towards C_(2)H_(6)and C_(3)H_(8).Furthermore,the dynamic breakthrough experiments revealed that purifying CH_(4)from natural gas in one-step can be achieved in Ni-MOF with high-purity(>99.8%)and productivity(346.0 cm^(3)/g).Most significantly,the production of Ni-MOF can be scalably synthesized at room temperature,rendering it promising potential for industrial *** combined advantages of exceptional separation performance,scalability,and cycle stability of Ni-MOF pave the way for one-step CH_(4)purification from natural gas.
