Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | This book, entitled "Plasma-Based Synthesis and Modification of Nanomaterials" is a collection of nine original research articles devoted to the application of different atmospheric pressure (APPs) and low-pressure (LPPs) plasmas for the synthesis or modification of various nanomaterials (NMs) of exceptional properties. These articles also show the structural and morphological characterization of the synthesized NMs and their further interesting and unique applications in different areas of science and technology. The readers interested in the capabilities of plasma-based treatments will quickly be convinced that APPs and LPPs enable one to efficiently synthesize or modify differentiated NMs using a minimal number of operations. Indeed, the presented procedures are eco-friendly and usually involve single-step processes, thus considerably lowering labor investment and costs. As a result, the production of new NMs and their functionalization is more straightforward and can be carried out on a much larger scale compared to other methods and procedures involving complex chemical treatments and processes. The size and morphology, as well as the structural and optical properties of the resulting NMs are tunable and tailorable. In addition to the desirable and reproducible physical dimensions, crystallinity, functionality, and spectral properties of the resultant NMs, the NMs fabricated and/or modified with the aid of APPs are commonly ready-to-use prior to their specific applications, without any initial pre-treatments.…

Taschenbuch. Zustand: Neu. Neuware - The volume unites conversations with four masters of Medieval Studies from east-central Europe: János Bak from Hungary, Jerzy K¿oczowski from Poland, Franti¿ek ¿mahel from the Czech Republic, and Herwig Wolfram from Austria. The interviews, made by younger colleagues, reveal engaging life stories, with numerous observations, anecdotes and experiences. The four scholars grew up before and during the war, under Nazi occupation, emerged as young scholars in the difficult post-war period, and, for most of their careers worked in the shadow of the Iron Curtain, two of them spending most of their lifetimes under communist regimes.The conversations focus on ways in which open-minded young intellectuals became medieval historians under difficult circumstances, how they experienced the long shadows of totalitarian regimes with their acute sensitivity for historical change, and how their perceptions of the world around them reflected back on their approach to medieval history. The histories of their nations were broken, most of them ceased to exist and then were re-established during their lifetimes, came under foreign domination, were split up, or had their territories shifted. These changes affected these scholars' identities and patriotic feelings, and their present was reflected in the distant mirror of the medieval past.…
