The Esfordi phosphate concentrate mainly contains fluorapatite, monazite, and xenotime as rare earth element (REE) minerals, accounting for 1.5% of rare earth metals. The monazite and xenotime minerals are refractory and their decomposition is only possible at high temperatures. Thus mechanical activation was used in the present work for this purpose. After 90 minutes of mechanical activation, ...
Mapping atomic displacement at the nanoscale is crucial for developing and optimizing strain-engineered devices. In today’s transistors, a slight deformation of the silicon lattice in the source-drain regions enhances their performance. And in the future, strain-induced electro-optic effects may potentially form the basis of an all-silicon electronic and photonic device. Transmission electron m...
The authors report the influence of CrN nanoisland inserted on growth of baseball-bat InN nanorods by plasma-assisted molecular beam epitaxy under In-rich conditions. By inserting CrN nanoislands between AlN nucleation layer and the Si (111) substrate, it was found that we could reduce strain form Si by inserting CrN nanoisland, FWHM of the x-ray rocking curve measured from InN nanorods from 3,...
Strain engineering technology is now routinely integrated in the wafer fabrication process to increase the carrier mobility and improve the device performance. Measuring and controlling the strain in nanoscaled materials is a critical for developing the state-of-art semiconductor devices [1-2]. High-performance strain-engineered ETSOI devices have been reported, such as strained SOI (SSDOI) for...
به منظور مطالعه اثر باکتریهای محرک رشد گیاه بر عملکرد کمی و کیفی دو رقم برنج، آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در 4 تکرار در سال زراعی 1388 در مزرعه تحقیقاتی موسسه ی تحقیقات برنج کشور در استان گیلان به اجرا در آمد. در این تحقیق، عامل رقم در 2 سطح (هاشمی و خزر) و تلقیح بذر با باکتری محرک رشد در 8 سطح (p. fluorescents strain 93 , p. fluorescents strain 103, p.fluorescents ...
