Book Description
Fe-ZnO catalysts were synthesized by impregnation technique and used to test the photocatalytic degradation of 2,4-DCP under visible light. Catalyst characteristic mainly presented wurtzite structure of ZnO, with crystalline size of 35-40 nm and 5-10 m2g−1 of specific surface area. Visible absorption of Fe-ZnO catalyst increased proportionally with Fe content. Oxidation state of Fe on ZnO surface was +3 and zero point charge was found at pH 9.5. Degradation experimental following Box-Behnken analysis provided an optimal condition of 2,4-DCP (initial concentration: 5.0 mg L−1) degradation under visible light at 5.0 mol% Fe-ZnO calcined at 700, and catalyst loading of 1.5 g L−1 (volume of synthetic waste water). Besides, the addition of 2 mM potassium persulfate (K2S2O8) could increase the degradation efficiency and the reaction could be completed within 90 min. The degradation performance on Fe-ZnO combined with K2S2O8 was 5 times higher than that using ZnO combined with K2S2O8. Reaction kinetics was fitted very well with the Langmuir-Hinshelwood model.

Book Description
Nuclear magnetic resonance has proved a uniquely versatile and powerful spectroscopic technique, with applications across chemistry, physics and medicine. The success of NMR and its constant redevelopment means that the literature is vast and wide-ranging. Each chapter in this volume is a distillation of the key recent literature in different areas covering the spectrum of NMR theory and practice, and including solution-state, solid-state and in-vivo NMR. These reports will be invaluable both for new researchers wishing to engage with literature for the first time, and for seasoned practitioners, particularly service managers, wishing to keep in touch with the ever-expanding ways in which NMR is used.

Book Description
In this book, original papers have been collected to demonstrate the efficient use of computer molecular dynamics simulation methods for the studying of nanoscale phenomena in the materials and life sciences. This book discusses modern molecular simulation methods for the study of molecular shape and properties in protein and polymer engineering, drugs and materials design, structure-function relationships, and related issues. This book contains the Proceedings of the MSSMBS-2014 and DSCMBS-2014 International Workshops which have been organised by the Joint Institute for Nuclear Research, the Institute of Bioorganic Chemistry of the Russian Academy of Sciences and S.U. Umarov Physical-Technical Institute of the Academy of Sciences of the Republic of Tajikistan. The research topics discussed in the MSSMBS'14 & DSCMBS'14 International Workshops are as follows: computer molecular simulation methods and approaches; molecular dynamics and Monte-Carlo techniques; modelling of biological molecules; physical and biochemical systems; material fabrication and design; drug design in medicine; computational and computing physics, chemistry, biology and medicine; GPU accelerated molecular dynamics and related techniques.
