"Il titolo dell'opera, Graecalis, implica un viatico romantico, simbolico ed evocativo: il nome di un vento che trasporti questi componimenti in fuga, verso altri territori, altre culture, lettori, autori. All'interno di Graecalis (Vento che soffia da nord-est a sud-ovest sul Mediterraneo centrale e meridionale nelle stagioni fredde) si susseguono, in ordine alfabetico: Simona Castellani con Un viaggio lungo la strada della vita, Cecilia Minisci con Pensando con l'Anima, Duilio Papi con Passeggiando sul palco, Massimo Pierozzi con Emozioni e Rime in Vernacolo Romano e Lingua, Laura Pingiori con Cerco un senso, Francesca Tornatore con I Pensieri di TO.SCA." (tratto dalla prefazione di Giuseppe Aletti)
Rumori, suoni di vita… speranze, tracce di umanità: con stile visionario, Cecilia scava dentro l’animo, per sondare i recessi del nostro passato… presente e futuro. Un viaggio nella storia senza tempo che si chiama vita, eppure, nonostante molti castelli di sabbia che l’uomo costruisce spinto da mozioni interiori, c’è un angolo di pace e tregua in questo Mondo, nel quale fermarsi, contemplare, ascoltare il rumore dei nostri cuori. Siamo ciò che diciamo, ma ancor di più siamo ciò che facciamo; ma il peso della nostra coscienza segnerà poi il destino dell’intera umanità. La domanda viatico per il lettore - nonostante tutto…è possibile restare umani? - . Una poesia che fa ...
La scritta parola cerca sempre nuovi percorsi e traiettorie da principiare, e questa raccolta, che si colloca in un più ampio progetto che ospiterà poeti e versi, raffigura un ossimoro: è un’antologia di tre autori, tuttavia si può esaminare come una monografia, sia per numero di testi presentati dai singoli autori, sia per impostazione e veste grafica. Il silenzio è il linguaggio di tutte le forti passioni, inserendosi nella tradizione letteraria e artistica dei grandi centri urbani (Parigi, Londra, Berlino, Venezia, Napoli, Palermo, Atene etc), che hanno realizzato stagioni indimenticabili della storia della cultura mondiale, ci indica che la poesia è dialogo, confronto e conoscenz...
In recent years silicon-centered radicals have played an important role in organic synthesis, polymer chemistry and material sciences. The aim of this book is to offer for the first time a description of silyl radicals within an interdisciplinary context, connecting structural characteristics and chemical properties to their application in different areas of chemistry. The first time different aspects of silyl radicals have been brought together Excellent reference tool for experienced practitioners of radical and/or silicon chemistry Presents various aspects of these intermediates in an original, comprehensive fashion This book is essential for anyone working in free radical and/or silicon chemistry as well as for those who want to approach these fields for the first time.
Provides, in one handbook, comprehensive coverage of one of the hottest topics in stereoselective chemistry Written by leading international authors in the field, this book introduces readers to C-H activation in asymmetric synthesis along with all of its facets. It presents stereoselective C-H functionalization with a broad coverage, from outer-sphere to inner-sphere C-H bond activation, and from the control of olefin geometry to the induction of point, planar and axial chirality. Moreover, methods wherein asymmetry is introduced either during the C-H activation or in a different elementary step are discussed. Presented in two parts?asymmetric activation of C(sp3)-H bonds and stereoselectiv...
From environmental remediation to alternative fuels, this book explores the numerous important applications of photocatalysis. The book covers topics such as the photocatalytic processes in the treatment of water and air; the fundamentals of solar photocatalysis; the challenges involved in developing self-cleaning photocatalytic materials; photocatalytic hydrogen generation; photocatalysts in the synthesis of chemicals; and photocatalysis in food packaging and biomedical and medical applications. The book also critically discusses concepts for the future of photocatalysis, providing a fascinating insight for researchers. Together with Photocatalysis: Fundamentals and Perspectives, these volumes provide a complete overview to photocatalysis.
Continuous-flow photochemistry is an expanding field within chemistry. It unites the mass transfer enhancement of flow chemistry with the high energy field density of microscale geometries. Moreover, it provides means to scale photochemical reactions efficiently.This book gives an overview of both technological and chemical aspects associated with photochemical processes in microreactors. It provides analysis, the first of its kind, of these new technologies developed within the field of photochemical processes, with a description and case studies of practical implementation. It specifically looks at:By providing a deeper understanding of underlying concepts, coupled with numerous examples, this book is an essential reference for chemistry students, researchers and professionals working on photochemistry, photoredox catalysis, flow chemistry, process chemistry and reactor engineering.
Praise for the Fourth Edition"Outstanding praise for previous editions.the single best general reference for the organic chemist."-Journal of the Electrochemical Society"The cast of editors and authors is excellent, the text is, in general, easily readable and understandable, well documented, and well indexed those who purchase the book will be sa
This volume reviews the recent advances in formation of C-F bonds and X-F bonds (X = heteroatom) to produce useful fluorinated molecules for pharmaceuticals, materials and more. Reactions and methods associated with fluorination, including monofluorination, difluorination, trifluorination and other polyfluorination that have emerged within the past few years are systematically discussed. With contributions from front-line researchers in this field from both academia and industry, this book provides a valuable resource for scholars, graduate students as well as professionals.
