A Textbook of "Metal Casting Process"
ISBN: 9786203024531 / Angielski / Miękka / 2024 / 64 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Metal casting is a modern process with ancient roots. In the metal casting process, metal shapes are formed by pouring molten metal into a mold cavity, where it is cooled and later extracted from the mold. Metal casting is arguably the earliest and most influential industrial process in history. It's used to make many of the metal objects used in our daily lives: automotive parts, train wheels, lamp posts, school bus pedals, and much more. Plus, metal casting foundries rely on metal recycling as a cost-efficient source of raw material, significantly reducing wasted scrap metal that might end...

Synthese und biologische Aktivität von Alkali-Erdmetallkomplexen
ISBN: 9786209001857 / Niemiecki / Miękka / 2025 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Um die Formeln und Strukturen der komplexen Verbindungen oder Komplexe zu erklären, die durch Übergangsmetallsalze mit molekularen Spezies wie Ammoniak gebildet werden, prägte Werner die Begriffe Primärvalenz und Sekundärvalenz. Diese Konzepte sind bis heute gültig, mit der Ausnahme, dass der Begriff "Oxidationszustand" den Begriff "primäre Valenz" ersetzt hat und der Begriff "Koordinationszahl" den Begriff "sekundäre Valenz". Werner hatte erkannt, dass ein Übergangsmetallsalz eine komplexe Verbindung bilden kann, in der das Metallion an eine Reihe von Gruppen gebunden ist, die nicht...

Synthèse et activité biologique des complexes de métaux alcalino-terreux
ISBN: 9786209001871 / Francuski / Miękka / 2025 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Afin d'expliquer les formules et les structures des composés complexes ou complexes formés par des sels de métaux de transition avec des espèces moléculaires telles que l'ammoniac, Werner a inventé les termes « valence primaire » et « valence secondaire ». Ces concepts restent valables aujourd'hui, à l'exception du terme « état d'oxydation » qui a remplacé « valence primaire » et du terme « nombre de coordination » qui a remplacé « valence secondaire ». Werner avait reconnu qu'un sel de métal de transition pouvait former un composé complexe dans lequel l'ion...

Newly synthesized Sr(II) complex and study of it's catalytic activity
ISBN: 9783659809736 / Angielski / Miękka / 2015 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. A coordination complex or metal complex is a structure consisting of a central atom or ion, bonded to a surrounding array of molecules or anions (ligands, complexing agents). The atom within a ligand that is directly bonded to the central atom or ion is called the donor atom. Polydentate (multiple bonded) ligands can form a chelate complex. A ligand donates at least one pair of electrons to the central atom/ion. Compounds that contain a coordination complex are called coordination compounds. The central atom or ion, together with all ligands forms the coordination sphere. Coordination refers...

Synthesis, Characterization And Catalytic Activity Of Ba(II) complexes
ISBN: 9783659785597 / Angielski / Miękka / 2015 / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In order to explain the formulae and structures of the complex compounds or complexes, formed by transition metal salts with molecular species such as ammonia, Werner coined the terms primary valence and secondary valence.. These concepts remain valid today except that the term oxidation state has replaced 'primary valence' and the term coordination number has replaced 'secondary valence' Werner had recognized that a transition metal salt could form a complex compound in which the metal ion became bonded to a number of groups which need not necessarily be the counter anions originally present...
