INFLUENCE OF SILANE TREATMENT ON WATER ABSORPTION AND MECHANICAL PROPERTIES OF PLA/SHORT BAMBOO FIBER-REINFORCED GREEN COMPOSITES

Shoma Maruyama、Hitoshi Takagi、Antonio Norio Nakagaito2019-07-15WIT transactions on engineering sciences

Green composites (GCs) consist of biodegradable resin and natural fibers. Due to the hydrophilicity of constituents, however, GCs are usually susceptible to water absorption. When GCs absorb water, the interface between the resin and fibers peels off, resulting in the shrinkage of the fibers after drying. In this stud…

Intertwined spin-orbital coupled orders in the iron-based superconductors

Morten H. Christensen、Jian Kang、Rafael M. Fernandes2019-07-15Physical review. B./Physical review. B

The underdoped phase diagram of the iron-based superconductors exemplifies the complexity common to many correlated materials. Indeed, multiple ordered states that break different symmetries but display comparable transition temperatures are present. Here we argue that such a complexity can be understood within a simp…
