	Polymer crystallization is one of the most challenging topics in polymer physics. At present, there still lacks of clear understanding in the polymer crystallization, especially in the induction of crystallization of a polymer material.. Poly(ε-caprolactone) (PCL) is the ideal model to study polymer crystallization due to its particular properties. A team from School of Materials Science and Engineering of TianJi...

	Hierarchical structured porous materials, which combine nanoparticles’ high chemical activity and microscale structures’ physical stability, are appealing materials as adsorbents in water treatment, energy storage and catalyst applications. However, it’s difficult to make clear the assembled structure through real time three dimensional imaging. A team from Key Laboratory for Molecular Nanostructures and Nanote...

	GaN material and related LED devices always suffered from the serious strains induced by the heteroepitaxy of III-N semiconductor on the most popular sapphire substrate. GaN material and related LED devices were grown by MOVPE on CPSS. The intrinsic property of dislocations in GaN on CPSS was examined by cross sectional TEM images. The stress ranging from 0.15GPa to 0.40GPa is obtained for GaN epilayer on CPSS,whi...

	The dendrites in every direction grow with the same rate and the dendrite“self-poisoning”is relieved via electric current. They firstly observe dendrite growth behavior of metal alloy with regulation of electromagnetic field via in situ visualization and reveal the internal mechanism of dendrite branches and grain refinement suppressed and promoted by electric field,respectively. ”The research provides the dire...

	Magnetic materials with high coercivity(Hc),perpendicular magnetic anisotropy(PMA)and magnetic energy product have great application potential in ultrahigh-density perpendicular magnetic recording media(~10Tb/inch2),high-performance permanent magnets and ferromagnetic electrodes of spintronic devices with high magnetic-noise immunity and thermal stability. These room-temperature magnetic characteristics make these...

	VO2 exhibits a well know metal-insulator transition(MIT)at 341K from a low temperature insulating phase to a high temperature metallic phase,accompanied by a structural transition from a monoclinic lattice to a rutile lattice. Due to the simple lattice structure and the amazing nature,VO2 is an ideal template for study on strong electronic interaction system. They obtained detail information of local structure aro...
