摘要:Abstract(#br)Aluminum alloy is widely used in industry. However, due to the low melting point and high toughness of aluminum alloy, the tool adhesive effect often occurs when cutting aluminum alloy, which may lead to tool failure. In this paper, the surface texture technolog...

摘要:High quality Sr4Ru3O10 nanoflakes are obtained by the scotch tape-based micro-mechanical exfoliation method. The metamagnetic transition temperature is found to decrease in line with the decrease of thickness, while the ferromagnetic (FM) phase, t...

摘要:Abstract(#br)A signed network includes positive edges, negative edges and “0” edges, the last of which denote potential relationships. However, “0” edges are commonly ignored in transformations of unbalanced networks. In this paper, we take “0” edges into account a...

摘要:Abstract(#br)The transformation of imbalanced networks into balanced ones has been widely studied, but the reverse transformation of balanced structure has received little attention. A balanced structure may sometimes reflect undesirable collective action, and breaking this balan...

摘要:Abstract(#br)A phase-shifted fiber Bragg grating (PS-FBG) fabricated by femtosecond laser phase mask technique is demonstrated. The PS-FBG fabricated by overlapped two types of fiber Bragg gratings (FBGs), which is a normal FBG and a titled fiber Bragg grating (TFBG). They a...

摘要:Abstract(#br)An asymmetric transfer hydrogenation of bulky aryl ketones with ammonia borane was successfully realized with chiral phosphoric acid (CPA) as catalyst and water as additive. A variety of optically active secondary alcohols were obtained in good to high yields wi...

摘要:Abstract(#br)Critical phenomenon of the noncentrosymmetric Cr 11 Ge 19 , which exhibits an itinerant ferromagnetic ground state, is investigated by scaling of the magnetic entropy change [Δ S M ( T , H )]. It is found that parameters δ FWHM (the full width at half maximum), ...

摘要:Abstract(#br)Many social systems have a set of opposite interactions such as friend/enemy, cooperation/competition and support/opposition. In these signed systems, there exist functional imbalances from the system-level view because of the existence of unbalanced interactions. Ho...

摘要:Abstract(#br)The physical properties of nanometer scale semiconductors are known to be sensitively influenced by their aspect ratios, but the intrinsic mechanisms still remain unclear. Shape-controlled anisotropic PbSe nanorods were obtained by means of the addition of MnCl ...
