Taschenbuch. Condizione: Neu. Neuware -Recently, nanotechnology is a burning field of science and popular among the researchers. It deals the formation and the activity of nanoparticles. Nanoparticles are used immensely due to its small size, orientation, physical properties, which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. Biological method (Bacteria, fungi, viruses, algae, and plants) in which plants or plants extract are used which is most suitable among physical and chemical method of synthesis of Silver nanoparticles. Plants extract have several biologically active compounds like phenols alkaloids, terpenes, which played important role in the formation of silver nanoparticles. The aim of present work was to synthesis of silver nanoparticles by green methods and its antibacterial activity in which we found that these nanoparticles have strong antibacterial activity due to presence of capping agent on silver nanoparticles.Books on Demand GmbH, Überseering 33, 22297 Hamburg 104 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -En los últimos tiempos, la nanotecnología es un campo científico candente y popular entre los investigadores. Trata de la formación y la actividad de las nanopartículas. Las nanopartículas se utilizan enormemente debido a su pequeño tamaño, orientación y propiedades físicas, que, según se ha demostrado, cambian el rendimiento de cualquier otro material que esté en contacto con estas diminutas partículas. El método biológico (bacterias, hongos, virus, algas y plantas), en el que se utilizan plantas o extractos de plantas, es el más adecuado entre los métodos físicos y químicos de síntesis de nanopartículas de plata. El extracto de plantas contiene varios compuestos biológicamente activos, como fenoles, alcaloides y terpenos, que desempeñan un papel importante en la formación de nanopartículas de plata. El objetivo del presente trabajo era la síntesis de nanopartículas de plata por métodos ecológicos y su actividad antibacteriana en la que se encontró que estas nanopartículas tienen una fuerte actividad antibacteriana debido a la presencia de agente de recubrimiento en nanopartículas de plata.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Spanisch.

Elle traite de la formation et de l'activité des nanoparticules. Les nanoparticules sont immensément utilisées en raison de leur petite taille, de leur orientation et de leurs propriétés physiques qui, selon les rapports, modifient les performances de tout autre matériau en contact avec ces minuscules particules. La méthode biologique (bactéries, champignons, virus, algues et plantes), dans laquelle des plantes ou des extraits de plantes sont utilisés, est la plus appropriée parmi les méthodes physiques et chimiques de synthèse des nanoparticules d'argent. Les extraits de plantes contiennent plusieurs composés biologiquement actifs comme les phénols, les alcaloïdes et les terpènes, qui jouent un rôle important dans la formation des nanoparticules d'argent. L'objectif de ce travail était de synthétiser des nanoparticules d'argent par des méthodes vertes et de déterminer leur activité antibactérienne. Nous avons constaté que ces nanoparticules ont une forte activité antibactérienne en raison de la présence d'un agent de fermeture sur les nanoparticules d'argent.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Französisch.

Trata-se da formação e da atividade das nanopartículas. As nanopartículas são muito utilizadas devido ao seu pequeno tamanho, orientação e propriedades físicas, que, segundo consta, alteram o desempenho de qualquer outro material que esteja em contacto com estas partículas minúsculas. O método biológico (bactérias, fungos, vírus, algas e plantas), no qual são utilizadas plantas ou extractos de plantas, é o mais adequado entre os métodos físicos e químicos de síntese de nanopartículas de prata. O extrato de plantas tem vários compostos biologicamente activos, como fenóis, alcalóides e terpenos, que desempenham um papel importante na formação de nanopartículas de prata. O objetivo do presente trabalho foi a síntese de nanopartículas de prata por métodos ecológicos e a sua atividade antibacteriana, tendo-se verificado que estas nanopartículas têm uma forte atividade antibacteriana devido à presença de um agente de cobertura nas nanopartículas de prata.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Portugiesisch.

Si occupa della formazione e dell'attività delle nanoparticelle. Le nanoparticelle vengono utilizzate immensamente grazie alle loro piccole dimensioni, all'orientamento e alle proprietà fisiche, che, secondo quanto riferito, sono in grado di modificare le prestazioni di qualsiasi altro materiale a contatto con queste minuscole particelle. Il metodo biologico (batteri, funghi, virus, alghe e piante), in cui si utilizzano piante o estratti di piante, è il più adatto tra i metodi fisici e chimici di sintesi delle nanoparticelle d'argento. Gli estratti di piante hanno diversi composti biologicamente attivi come fenoli, alcaloidi e terpeni, che hanno svolto un ruolo importante nella formazione delle nanoparticelle d'argento. Lo scopo del presente lavoro è stato quello di sintetizzare nanoparticelle d'argento con metodi ecologici e la sua attività antibatterica; abbiamo scoperto che queste nanoparticelle hanno una forte attività antibatterica grazie alla presenza di un agente di capping sulle nanoparticelle d'argento.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Italienisch.

Taschenbuch. Condizione: Neu. Neuware -In letzter Zeit ist die Nanotechnologie ein brennendes Feld der Wissenschaft und bei den Forschern sehr beliebt. Sie befasst sich mit der Bildung und der Aktivität von Nanopartikeln. Nanopartikel werden aufgrund ihrer geringen Größe, Ausrichtung und physikalischen Eigenschaften, die Berichten zufolge die Leistung jedes anderen Materials, das mit diesen winzigen Partikeln in Berührung kommt, verändern, in großem Umfang eingesetzt. Die biologische Methode (Bakterien, Pilze, Viren, Algen und Pflanzen), bei der Pflanzen oder Pflanzenextrakte verwendet werden, ist unter den physikalischen und chemischen Methoden zur Synthese von Silber-Nanopartikeln am besten geeignet. Pflanzenextrakte enthalten mehrere biologisch aktive Verbindungen wie Phenole, Alkaloide und Terpene, die eine wichtige Rolle bei der Bildung von Silbernanopartikeln spielen. Das Ziel der vorliegenden Arbeit war die Synthese von Silber-Nanopartikeln durch grüne Methoden und ihre antibakterielle Aktivität, wobei wir feststellten, dass diese Nanopartikel aufgrund des Vorhandenseins eines Kappungsmittels auf Silber-Nanopartikeln eine starke antibakterielle Aktivität haben.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Deutsch.
