Stability, Equilibrium Morphology and Hydration of ZrC (111) and (110) Surfaces with H2O: A Periodic DFT and Atomistic Thermodynamics Study

29.07.2015 | OSEI-AGYEMANG Eric; Jean-François Paul; Romain Lucas; Foucaud sylvie; Sylvain Cristol, Physical Chemistry Chemical Physics, 2015

ZrC is a non-oxide Ultra High Temperature Ceramic (UHTC) with excellent physical and mechanical properties used in nuclear plants and jet propulsion engines. However, mechanical properties can be lost because of the easy oxidation of its grain surfaces. One way of dealing with such problem is to ...

Effects of maleic anhydride grafted polyethylene on rheological, thermal, and mechanical properties of ultra high molecular weight polyethylene/poly(ethylene glycol) blends

25.07.2015 | Shuai He, Hui He, Yingchun Li, Dongqing Wang, Journal of Applied Polymer Science, 2015

ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) has gained considerable fame due to its excellent wear and mechanical properties, though the inferior processability has restricted its further extensive applications. In this study, a combination of UHMWPE and poly(ethylene glycol) ...

Synthesis of Nanocrystals and Particle Size Effects Studies on the Thermally Induced Spin Transition of the Model Spin Crossover Compound [Fe(phen)2(NCS)2]

24.07.2015 | Francisco Javier Valverde-Muñoz; Ana B. Gaspar; Sergii I. Shylin; Vadim Ksenofontov; José A. Real, Inorganic Chemistry, 2015

Surfactant-free nanocrystals of the model spin-crossover compound [Fe(phen)2(NCS)2] (phen: 1,10-phenanthroline) have been synthesized applying the reverse micelle technique. The morphology of the nanocrystals, characterized by scanning electronic microscopy, corresponds to rhombohedric platelets ...

The ageing of poly (ε‐caprolactone)

23.07.2015 | K. Phillipson, M. J. Jenkins, J.N. Hay, Polymer International, 2015

Abstract Partially crystallizedpoly (ε‐caprolactone), PCL, has been stored for up to 6 months at various temperatures from ‐18 to 50 oC and the change in tensile properties, crystallinity and melting behaviour followed with storage time. The Young's modulus, yield and drawing stress were ...

High‐Performance Segmented Liquid Crystalline Copolyesters

21.07.2015 | Ashley M. Nelson, Gregory B. Fahs, Robert B. Moore, Timothy E. Long, Macromolecular Chemistry and Physics, 2015

The ability of a multiphase copolymer to exhibit both the physical properties of liquid crystalline and elastomeric polymers enables a variety of emerging applications. Traditional synthetic methods often require many steps to achieve such diversity in a copolymer. This work describes the ...

Impact of electrospinning process parameters on the measured current and fiber diameter

17.07.2015 | Siavash Sarabi‐Mianeji, Jennifer Scott, Danny J.Y.S. Pagé, Polymer Engineering and Science, 2015

In this article, polycaprolactone (PCL) nanofibres were processed by electrospinning using a 3:1 ratio of tetrahydrofuran to methanol as solvent. The solvent choice was motivated by the possibility of greener alternatives to the halogenated compounds most often used for electrospinning. The ...
