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...

New Stabilizers for PVC Based on Benzothiazole Complexes
ISBN: 9783844323580 / Angielski / Miękka / 2011 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The work described in this thesis, potasium-2-amino acetate benzothiazole chelate complexes were prepared. Infrared, ultraviolet-visible, spectrophotometric techniques, magnetic susceptibility, atomic absorption conductivity measurement and other physical properties were used to characterize the free ligand and the above chelate complexes. All these compounds were act as stabilizer in PVC films. The rate of photodegradation and photostabilization of PVC film were monitored by measuring the carbonyl, polyene and hydroxyl indices (Ico, Ipo and IoH) values as afunction with irradiation time...

General description of heterocyclic derivatives
ISBN: 9783847337416 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Heterocycles play an important role in biochemical processes because the side groups of the most typical and essential constituents of living cells are based on aromatic heterocycles. The presence of heterocycles in biology, pharmacology, optics, electronics, etc. is very well known. Between them, sulfur and nitrogen-containing heterocyclic compounds have maintained the interest of researchers through the development of organic synthesis. Furthermore, azole antifungal agents are the largest class of antimycotics available today. Fused and pendent heterocyclic rings are a ubiquitous feature of...
