Nano Crystalline Lanthanum Ferrite: Synthesis and Characterization
ISBN: 9783659376153 / Angielski / Miękka / 2013 / 92 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Nano crystalline orthoferrite powders were synthesized at low temperatures by solution combustion synthesis using glycine as a fuel at different fuel to oxidizer ratios. During this process of combustion synthesis, more and less flames were observed at more fuel to oxidizer ratios. From X-ray diffraction, for instance the formation of a single phase of LaFeO3 with the perovskite structure was observed at lower calcination temperatures of 300 C. The lanthanum ferrite crystalline size is formed with orthorhombic structural and space group of the tolerance factor was observed. Excellent thermal...

Structure and Properties of 3D Transition Metal Doped Zno
ISBN: 9783659588426 / Angielski / Miękka / 2014 / 196 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. ZnO based semiconductors as transparent electrodes have given wide range of applications in optoelectronic devices due to their wide band gap replacing the conventional GaN semiconductors. This book is the compilation of the work of Venkaiah Malapati which deals with the synthesis and characterization of an interesting room temperature undoped and 3d transition metal doped ZnO thin films by rf magnetron sputtering. this work addresses the following three major questions... (1) what is the effect of working gas pressure on the properties of undoped and Mn, Fe and Mn-Fe co-doped ZnO thin films....

Ethnomedicine of Vizianagaram District
ISBN: 9783659409554 / Angielski / Miękka / 2013 / 284 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Ethnomedicine is an area of research that deals with medicines derived from plants, animals and minerals. Its knowledge endowed with the aborigines is the resultant of millennia of experience, transmitted from generation to generation by oral tradition. Since the beginning of civilization, people have used plants as medicine and out of thousand of plants used by the tribals to cure ailments hundreds only found their way in all the systems of medicine in vogue today. The investigation is an attempt to explore the ethnomedicinal system of the aboriginals of Vizianagaram district of Andhra...
