ISBN: 9786206166122 / Niemiecki / Miękka / 2024 / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Die Verwendung von Pflanzenextrakten zur Synthese von Metalloxid-Nanopartikeln (grüne Synthese) stellt aufgrund ihrer ökologischen Nachhaltigkeit, der niedrigen Kosten, des geringen Energieverbrauchs, der einfachen Herstellung und der Umweltfreundlichkeit eine vielversprechende Alternative zu herkömmlichen physikalischen oder chemischen Synthesemethoden dar. In der vorliegenden Arbeit haben wir Silberoxid- und Nickeloxid-Nanopartikel synthetisiert, indem wir den Pflanzenextrakt der Pflanze H. hirsuta als Reduktionsmittel und Stabilisator für Silber- und Nickelionen zur Erzeugung der...

ISBN: 9786206725060 / Francuski / Miękka / 2024 / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. L'utilisation d'extraits de plantes pour la synthèse de nanoparticules d'oxyde métallique (synthèse verte) représente une alternative prometteuse aux méthodes de synthèse conventionnelles, qu'elles soient physiques ou chimiques, en raison de leur durabilité environnementale, de leur faible coût, de leur faible consommation d'énergie, de leur facilité de production et de leur respect de l'environnement. Dans le présent travail, nous avons synthétisé des nanoparticules d'oxyde d'argent et d'oxyde de nickel en exploitant l'extrait végétal de la plante H. hirsuta comme agent...

Biosynthesis, characterization and application of nanoparticles
ISBN: 9786206166139 / Angielski / Miękka / 2024 / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The use of plant extracts for the synthesis of metal oxide nanoparticles (green synthesis) represents a promising alternative to conventional synthesis methods, whether physical or chemical, due to their environmental sustainability, low cost, low energy consumption, ease of production and environmental friendliness. In the present work, we have synthesized silver oxide and nickel oxide nanoparticles by exploiting the plant extract of the H. hirsuta plant as a reducing agent and stabilizer of silver and nickel ions for the creation of said nanoparticles.

Two-Dimensional Systems: From Introduction to State of the Art
ISBN: 9783319201153 / Angielski / Twarda / 2015 / 295 str. Termin realizacji zamówienia: ok. 20 dni roboczych. A solution permitting the stabilization of 2-dimensional (2-D) continuous-time saturated system under state feedback control is presented in this book. The problems of delay and saturation are treated at the same time. The authors obtain novel results on continuous 2-D systems using the unidirectional Lyapunov function. The control synthesis and the saturation and delay conditions are presented as linear matrix inequalities. Illustrative examples are worked through to show the effectiveness of the approach and many comparisons are made with existing results. The second half of the...

Heterocyclic Corrosion Inhibitors
ISBN: 9786206160618 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This study investigates the use of new heterocyclic compounds, specifically Imidazole derivatives, as corrosion inhibitors for steel in acidic media. The objective is to establish correlations between molecular structure and corrosion inhibition based on the substituent effect in each series of molecules. The study employs various techniques, including gravimetry, electrochemical impedance spectroscopy, polarization measurements, scanning electron microscopy, and molecular dynamics simulation. Results show a direct link between the parameters obtained and the changing substituent in the basic...

Saturated Switching Systems
ISBN: 9781447128991 / Angielski / Miękka / 2012 / 288 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Saturated Switching Systems treats the problem of actuator saturation, inherent in all dynamical systems by using two approaches: positive invariance in which the controller is designed to work within a region of non-saturating linear behaviour; and saturation technique which allows saturation but guarantees asymptotic stability. The results obtained are extended from the linear systems in which they were first developed to switching systems with uncertainties, 2D switching systems, switching systems with Markovian jumping and switching systems of the Takagi-Sugeno type. The text represents a...

Pluralism and Secularism In Cunningham Graham's Mogreb-El-Acksa
ISBN: 9783639862201 / Angielski / Miękka / 2015 / 140 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Not all the travellers who had trodden the orient during the heightened era of imperialism comply with the defining precepts of what Edward Said has labelled Orientalism. The worldviews of some travel writers were not unilaterally levelled by the juggernaut of imperialism. From within the hustle and bustle of colonial rhetoric, some voices retain a poignant independence that interrogates the unicity, generalization, stability, and homogeneity with which Said has sealed up his seminal thesis Orientalism. Following a multidisciplinary cultural studies approach, the present thesis interprets...
