It is a challenge to identify each phase in multi-component polymer system and uniquely determine the interfacial properties between different phases. Using atomic force microscopy nanomechanical mapping (AFM-NM) AFM-based infrared spectroscopy (AFM-IR), we phase, visualize structural developments, blend of three polymers: high-density polyethylene (HDPE), polyamide (PA6) poly(styrene-b-ethylen...

It is recently demonstrated that amorphous Ge anode shows higher reversible Na-ion storage capacity (590 mA h g-1) than crystallized Ge anode (369 mA h g-1). Here, amorphous GeO x anode is prepared by a simple wet-chemistry reduction route at room temperature. The obtained amorphous GeO x shows a porous hierarchical architecture, accompanied with a Brunauer-Emmett-Teller surface area of 159 m2 ...

Understanding habitat use of critically endangered North Pacific right whales (NPRWs, Eubalaena japonica) is important to better evaluate the potential effects of anthropogenic activities and climate change on this species. Satellite transmitters were deployed on individual right whales in 2004, 2008 and 2009 to investigate whether their space-use patterns in the Southeastern Bering Sea (SEBS) ...

Evapotranspiration (ET) estimates are particularly needed for monitoring the available water of arid lands. Remote sensing data offer the ideal spatial and temporal coverage needed by irrigation water management institutions to deal with increasing pressure on available water. Low spatial resolution (LR) products present strong advantages. They cover larger zones and are acquired more frequentl...

Syndiotactic Polystyrene （SPS） has excellent electrical properties, and is expected to be applied high-frequency circuit boards. We made a study of the formation metal layer on smooth surface SPS resin through continuous plasma sputtering process, examined effects crystallinity addition styrene-ethylenbutylene-styrene （SEBS） peel strength. also investigated mechanism behind increased strength u...

Two poly(3-hexylthiophene) (P3HT) macromers containing a donor polymer with a polymerizable methacrylate (MA) end group, P3HT-CH2-MA and P3HT-(CH2)2-MA, have been synthesized, and P3HT-(CH2)2-MA has been successfully homopolymerized and copolymerized with methyl methacrylate (MMA) into stereoregular brush polymers and graft copolymers, respectively, using chiral ansa-zirconocene catalysts. Macr...
