Molecular Dynamics Study of Wetting Behavior of Grafted Thermo-responsive PNIPAAm Brushes

02.02.2016 | Debdip Bhandary; Zuzana Benkova; Maria Natália Dias Soeiro Cordeiro; Jayant K Singh, Soft Matter, 2016

In this work, the effect of temperature on the contact angle of a water droplet on the grafted thermo-responsive polymer poly–(N-isopropylacrylamide) (PNIPAAm) brushes is studied using all-atom molecular dynamics simulations in the temperature range of 270 K-330 K. A shift from 55º to 65º in ...

Growth and Physiological Responses of Quinoa to Drought and Temperature Stress

29.01.2016 | A. Yang, S. S. Akhtar, M. Amjad, S. Iqbal, S.‐E. Jacobsen, Journal of Agronomy and Crop Science, 2016

Abstract Quinoa (Chenopodium quinoa Willd.), traditionally called the mother of grains, has the potential to grow under high temperatures and drought, tolerating levels regarded as stresses in other crop species. A pot experiment was conducted in a climate chamber to investigate the potential ...

Bipyridinium‐bis(carboxylate) Radical Based Materials: X‐ray, EPR and Paramagnetic Solid‐State NMR Investigations

29.01.2016 | Oksana Toma, Maxime Leroux, Nicolas Mercier, Magali Allain, Abdel Hadi Kassiba, Shashi Kumar Kumara Swamy, Jens Dittmer, European Journal of Inorganic Chemistry, 2016

Abstract The zwitterionic 1,1′‐bis(4‐carboxyphenyl)‐4,4′‐bipyridinium (bp4pc) has been synthesized and crystals of its hydrated form bp4pc·2H2O and of its protonated reduced form H‐bp4pc have been obtained. Upon heating, bp4pc·2H2O undergoes partial dehydration, leading to bp4pc·H2O at 160 °C, ...

[Report] Activation of Cu(111) surface by decomposition into nanoclusters driven by CO adsorption

29.01.2016 | Baran Eren; Danylo Zherebetskyy; Laerte L. Patera; Cheng Hao Wu; Hendrik Bluhm; Cristina Africh; Lin-Wang Wang; Gabo ..., Science , 2016

The (111) surface of copper (Cu), its most compact and lowest energy surface, became unstable when exposed to carbon monoxide (CO) gas. Scanning tunneling microscopy revealed that at room temperature in the pressure range 0.1 to 100 Torr, the surface decomposed into clusters decorated by CO ...
