Construction of Smart Temperature-Responsive GPx Mimic Based on the Self-Assembly of Supra-Amphiphiles

24.11.2015 | Huixin Zou; Hongcheng Sun; Liang Wang; Liulu Zhao; Jiaxi Li; Zeyuan Dong; Quan Luo; Jiayun Xu; Junqiu Liu, Soft Matter, 2015

Glutathione peroxidase (GPx) is a major defense against hydroperoxides as a kind of seleno-enzyme that protects cells from oxidative damage. A supramolecular vesicle with controllable GPx activity and morphology has been successfully constructed by the self-assembly of supra-amphiphiles formed by ...


Insight into Al existing form and its role on microstructure and properties of Cr1−xAlxN films

20.11.2015 | Yingying Fu, Hongxuan Li, Li Ji, Xiaohong Liu, Liu Liu, Huidi Zhou, Jianmin Chen, Surface and Interface Analysis, 2015

A series of Cr1−xAlxN (where x denotes the atom fraction of Al in Cr1−xAlxN film) films with different Al contents have been deposited by unbalanced reactive magnetron sputtering technique. The chemical composition, microstructure, surface morphology, cross‐sectional structure, mechanical ...


Characterization, morphology, and biodegradation of bioplastic fertilizer (BpF) composites made of poly(Butylene succinate) blended with oil palm biomass and fertilizer

19.11.2015 | Harmaen Ahmad Saffian, Khalina Abdan, Mohd Ali Hassan, Azowa Ibrahim, Polymer Composites, 2015

Poly(butylene succinate) (PBS) is a versatile biodegradable polymer that can be processed into slow‐release bioplastic fertilizer (BpF) composites using twin screw extruder extrusion method, with controlled formulation and temperature. In this study, slow‐release BpF composites were created by ...


Development of a Smart, Anti‐Water Polyurethane Polymer Hair Coating for Style Setting

19.11.2015 | Liu Yan, Liu Yijun, Jinlian Hu, Ji FengLong, Lv Jing, Chen Shao Jun, Zhu Yong, International Journal of Cosmetic Science, 2015

Abstract Objective The goal of this work was to develop a novel polyurethane polymer coating for the surface of the hair that could be used for style setting via the shape memory effect. The features of the films are in accordance with conventional hair styling methods used in the ...


About the Interactions Controlling Nafion’s Viscoelastic Properties and Morphology

19.11.2015 | Jan-Patrick Melchior; Thomas Bräuniger; Andreas Wohlfarth; Giuseppe Portale; Klaus-Dieter Kreuer, Macromolecules, 2015

Interactions controlling the viscoelastic properties of Nafion are identified by investigating morphological changes induced through stretching at a wide range of controlled temperature and relative humidity. 2H-goniometer NMR exploiting the pseudonematic effect in D2O-containing membranes ...


Synthesis of Hexagonal Boron Nitride Monolayer: Control of Nucleation and Crystal Morphology

18.11.2015 | Yijing Stehle; Harry M. Meyer, III; Raymond R. Unocic; Michelle Kidder; Georgios Polizos; Panos G. Datskos; Roderick ..., Chemistry of Materials, 2015

Monolayer hexagonal boron nitride (hBN) attracts significant attention due to the potential to be used as a complementary two-dimensional dielectric in fabrication of functional 2D heterostructures. Here we investigate the growth stages of the hBN single crystals and show that hBN crystals change ...


Influence of AlN nucleation layer on vertical breakdown characteristics for GaN‐on‐Si

17.11.2015 | J. J. Freedsman, A. Watanabe, Y. Yamaoka, T. Kubo, T. Egawa, physica status solidi (a), 2015

A study of metal‐organic chemical vapor deposition (MOCVD) grown AlN nucleation layer (NL) on breakdown characteristics for GaN‐on‐Si is presented. It is widely believed that AlN NL can act as an insulator because of its large band gap ∼6.2 eV. On contrary, this study of AlN NL/Si reveals ...


Silicon Oxycarbide Films Produced by Remote Microwave Hydrogen Plasma CVD using a Tetramethyldisiloxane Precursor: Growth Kinetics, Structure, Surface Morphology, and Properties 

17.11.2015 | Aleksander M. Wrobel, Pawel Uznanski, Agnieszka Walkiewicz‐Pietrzykowska, Chemical Vapor Deposition, 2015

Amorphous hydrogenated silicon oxycarbide (a‐SiCO:H) thin films are produced by remote microwave hydrogen plasma CVD using 1,1,3,3‐tetramethyldisiloxane precursor. The effect of substrate temperature (TS) on the chemical structure and some properties of resulting a‐SiCO:H films is reported. The ...


Investigations on rheological and mechanical behavior of poly(3‐Hydroxybutyrate)/cellulose nanocrystal based nanobiocomposites

17.11.2015 | Prodyut Dhar, Umesh Bhardwaj, Amit Kumar, Vimal Katiyar, Polymer Composites, 2015

The work focused on the formation of percolation network by cellulose nanocrystals (CNCs) in poly(3‐hydroxybutyrate) (PHB) matrix, which affects the rheological and mechanical properties of the polymer. Rheological investigations revealed the formation of a percolation network in the fabricated ...


Stabilization of Palladium Nanoparticles on Nanodiamond–Graphene Core–Shell Supports for CO Oxidation

16.11.2015 | Liyun Zhang, Hongyang Liu, Xing Huang, Xueping Sun, Zheng Jiang, Robert Schlögl, Dangsheng Su, Angewandte Chemie International Edition, 2015

Abstract Nanodiamond–graphene core–shell materials have several unique properties compared with purely sp2‐bonded nanocarbons and perform remarkably well as metal‐free catalysts. In this work, we report that palladium nanoparticles supported on nanodiamond–graphene core–shell materials ...
