Toughening effect of CPE on ASA/SAN binary blends at different temperatures

05.02.2016 | Zepeng Mao, Jun Zhang, Journal of Applied Polymer Science, 2016

ABSTRACT The effect of chlorinated polyethylene (CPE) on the impact toughness of acrylonitrile–styrene–acrylic (ASA) terpolymer/styrene–acrylonitrile copolymer (SAN) binary blends (25/75, w/w) was systematically investigated at three different temperatures (−30 °C, 0 °C, and 23 °C). With the ...

Engineering of Spin Injection and Spin Transport in Organic Spin Valves Using π‐Conjugated Polymer Brushes

05.02.2016 | Rugang Geng, Anandi Roy, Wenbo Zhao, Ram Chandra Subedi, Xiaoguang Li, Jason Locklin, Tho Duc Nguyen, Advanced Functional Materials, 2016

Charge transport in amorphous organic semiconductors is governed by carriers hopping between localized states with small spin diffusion length. Furthermore, the interfacial resistance of organic spin valves (OSVs) is poorly controlled resulting in controversial reports of the magnetoresistance ...

Self-Assembly of Graphene Nanoblisters Sealed to a Bare Metal Surface

05.02.2016 | Rosanna Larciprete; Stefano Colonna; Fabio Ronci; Roberto Flammini; Paolo Lacovig; Nicoleta Apostol; Antonio Politan ..., Nano Letters, 2016

The possibility to intercalate noble gas atoms below epitaxial graphene monolayers coupled with the instability at high temperature of graphene on the surface of certain metals has been exploited to produce Ar-filled graphene nanosized blisters evenly distributed on the bare Ni(111) surface. We ...

Effect of Sodium Oxides in Ash Composition on Ash Fusibility

05.02.2016 | Yang Wang; Yu Xiang; Dongxu Wang; Changqing Dong; Yongping Yang; Xianbin Xiao; Qiang Lu; Ying Zhao, Energy & Fuels, 2016

Ash fusibility is closely associated with ash slagging, which has great significance on efficiency and cleanliness of thermal conversion and coal utilization. Not being a dominant component of coal ash, Na2O is believed to be an inducement for slagging problems. In this study, for the realization ...

MOCVD growth of ZnO nanowires on Ni‐W metallic substrates

03.02.2016 | Gaëlle Amiri, Mohamed Halaoui, Diana Nathalie Montenegro, Pierre Galtier, Vincent Sallet, physica status solidi (c), 2016

Abstract Here we investigate the possibility to grow ZnO nanowires on (100) textured Ni‐W substrates by MOCVD at 850 °C. Due to the oxidation of Ni, direct growth of ZnO nanowires on those metallic substrates was not achieved whereas it was easily obtained on sapphire in the same conditions. ...

The electrospun polyhydroxybutyrate fibers reinforced with cellulose nanocrystals: Morphology and properties

03.02.2016 | Piyaporn Kampeerapappun, Journal of Applied Polymer Science, 2016

ABSTRACT Polyhydroxybutyrate (PHB) has been used in the biomedical field. However, the poor mechanical properties of PHB have limited its application. Here, electrospun fibrous nanocomposite mats reinforced with cellulose nanocrystals (CNCs) were fabricated by using PHB as polymeric matrix. ...
