ISBN: 9786203269260 / Niemiecki / Miękka / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Die Koordinationschemie von Hydrazonen ist ein intensives Studiengebiet und zahlreiche Übergangsmetallkomplexe dieser Liganden wurden untersucht, was aus dem Interesse an den biologischen und pharmakologischen Eigenschaften dieser Hydrazone resultierte. Es ist auch bekannt, dass Mono- und Bis-Hydrazone aufgrund ihrer antibakteriellen, tuberkulostatischen und fungiziden Eigenschaften sowie ihrer Aktivitäten gegen bestimmte Arten von Krebs und Mikroorganismen breite Anwendung in der Medizin finden. Darüber hinaus bilden Benzothiazol und seine Derivate eine wichtige Verbindungsklasse mit...

Photostabilization of PVC: Principles and Applications
ISBN: 9783659302077 / Angielski / Miękka / 2012 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The low cost and excellent performance of poly(vinyl chloride) (PVC) make it a very attractive and suitable plastic for a wide variety of applications. With respect to the production and consumption of synthetic materials, it stands third in the world after polyethylene and polypropylene. However, PVC suffers from poor thermal and light stability. It undergoes rapid autocatalytic dehydrochlorination upon exposure to heat and light during its molding and use, respectively. As a result, conjugated polyene sequences are formed from the beginning of the reaction, and they give rise to...

Synthèse d'ions métalliques avec des complexes de benzothiazole
ISBN: 9786203269338 / Francuski / Miękka / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. La chimie de coordination des hydrazones est un domaine d'étude intensif et de nombreux complexes de métaux de transition de ces ligands ont été étudiés, ce qui découle de l'intérêt porté aux propriétés biologiques et pharmacologiques de ces hydrazones. On sait également que les mono et bis-hydrazones trouvent de larges applications en médecine en tant que préparations physiologiques actives, en raison de leurs propriétés antibactériennes, tuberculostatiques, fongicides ainsi que de leurs activités contre certains types de cancers et de micro-organismes. En outre, le...

Development of Hazardness Index at Urban Uncontrolled Intersections
ISBN: 9783639263800 / Angielski / Miękka / 2010 / 176 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Historically, highway safety agencies in developed countries have relied heavily on reported traffic accidents to identify problem locations. Most highway safety professionals, however, recognize the shortcomings of relying on accidents as the sole criterion. The most important shortcoming occurs when there is no reliable accident data, which are identified by accurate accident locations. Thus the primary objective of this book is to develop a model when hazardous urban uncontrolled intersections can be identified by use of an indicator, which depends on the geometric and traffic feature of...

New Trends in the Photochemistry of Polymers
ISBN: 9783639861709 / Angielski / Miękka / 2015 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Polymer science is, of course, driven by the desire to produce new materials for new applications. The success of materials suchas polyethylene, polypropylene, poly(vinyl chloride) and polystyrene is such that these materials are manufactured on a huge scaleand are indeed ubiquitous.It is widely recognized that ultraviolet rays in sunlight (wavelengths between 280 nm and 400 nm) is an important factorcausing photodegradation to some organic substances such as polymers.UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and...

Photolysis of Tris(ethylxanthato) Chromium (III) complex in DMSO
ISBN: 9783844331714 / Angielski / Miękka / 2011 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In the present work we prepared tris(alkylxanthato)chromium(III) and intended to study the photochemistry of these complexes in dimethyl sulfoxide. These complexes might be useful in many applications. Moreover, metal chelate with metals at high oxidation state is active in the enhancement of photodegradation of plastic and therefore, might serve as photocatalyst to treat the plastic waste pollution problem. The effect of number of methyl group in these complexes has been also studied. This work also deals with the photochemical reaction and determination of quantum yields and reactivity...
