This concise book delves into the innovative use of carrageenan in the green synthesis of metal oxide nanoparticle synthesis. It explores this emerging approach’s mechanisms, highlighting its benefits over traditional syntheses. The unique properties imparted by carrageenan to metal oxide nanoparticles and how these enhance the material for various applications are also discussed. Furthermore, concerns regarding the scalability of this green synthesis are explored, particularly the challenges faced in large-scale production, reproducibility, economics, and environmental sustainability.Uniquely focuses on the carrageenan-mediated approach to metal oxide nanoparticle synthesisDetails the mechanisms specific to metal oxide nanoparticle synthesis and the relevance of carrageenan in nanoparticle enhancement (through doping)Covers the scalability and reproducibility of this emerging approach to bridge research and industrial productionThis book serves as a primer for researchers and advanced students in materials science, chemistry, and chemical engineering to aid them in connecting their existing knowledge with the related peer-reviewed literature.
This fully illustrated study details Germany and Italy’s failed development of World War II aircraft carriers, and the naval aviation ships that the two Axis powers sent into action in their place.The quest for a modern aircraft carrier was the ultimate symbol of the Axis powers’ challenge to Allied naval might, but fully-fledged carriers proved either too difficult, expensive or politically unpopular for either to make operational. After the Anglo-German Naval Agreement of 1935, Hitler publicly stated his intention to build an aircraft carrier, the Graf Zeppelin, which was launched in 1938. A year later, the ambitious fleet-expansion Z-Plan, was unveiled with two additional aircraft carriers earmarked for production . However, by the beginning of World War II, Graf Zeppelin was not yet completed and work was halted. Further aircraft carrier designs and conversion projects such as the ocean liner Europa and heavy cruiser Seydlitz were considered but, in January 1943, all construction work on surface vessels ceased and naval resources were diverted to the U-boat Campaign.This book explains not only the history of Germany’s famous Graf Zeppelin fleet carrier and German carrier conversion projects but also Italy’s belated attempt to convert two of her ocean liners into carriers. It considers the role of naval aviation in the two countries’ rearmament programmes and describes how ultimately it was only Italian seaplane carriers and German ocean-going, catapult-equipped flying boat carriers that both Axis powers did eventually send into combat.
Questo libro descrive un progetto sul controllo della sedia a rotelle utilizzando i MEMS. I MEMS sono fissati sulla mano. Ogni volta che la mano si muove in una particolare direzione, il movimento meccanico della mano viene riconosciuto dai MEMS. I MEMS convertono il movimento meccanico della mano in segnali elettrici equivalenti (coordinate X, Y, Z) e li inviano al microcontrollore. La sedia a rotelle dotata di due motoriduttori a corrente continua. Questi motori si muovono in direzione 2D con l'aiuto del ponte H. Con l'aiuto dei LED possibile visualizzare lo stato della sedia a rotelle: avanti, indietro, sinistra, destra.I sistemi microelettromeccanici (MEMS) sono la tecnologia dei dispositivi meccanici molto piccoli azionati dall'elettricit e si fondono su scala nanometrica nei sistemi nanoelettromeccanici (NEMS) e nella nanotecnologia. I MEMS sono costituiti da componenti di dimensioni comprese tra 1 e 100 micrometri (cio tra 0,001 e 0,1 mm) e i dispositivi MEMS hanno generalmente dimensioni comprese tra 20 micrometri (20 milionesimi di metro) e un millimetro. Di solito sono costituiti da un'unit centrale che elabora i dati, il microprocessore, e da diversi componenti che interagiscono con l'esterno, come i microsensori.
