There have been growing interests in direct patterning of metallic contents on the surface of the substrate without including complex steps of the micro fabrication lithography process. The direct fabrication process using ink-jet printing can be expected to be a powerful tool for both nanotechnology research and applications such as micro electronics. Inkjet printers operate by propelling vari...
The objective of this study was to develop a supported tri-metallic catalyst (nano-Ni-La-Fe/γ-Al2O3) for tar removal in biomass steam gasification, to significantly enhance the quality of the produced gas. For this purpose, the supported tri-metallic catalysts were prepared by a deposition-precipitation (DP) method. Different analytical approaches were used to characterize the synthesized catal...
In this paper, the possibility of mechanical coating of aluminum with either Ni or SiC using planetary ball mill was studied. The Al substrate was fixed inside of the vial lid of a planetary ball mill filled with milling balls and starting powder. The phase analysis and crystallite size measurement of the coatings were carried out using X-ray diffraction (XRD) method. Scanning electron micro...
The design of novel functional biomaterials that possess similar mechanical attributes as human bones, accompanied with admirable osteogenesis to replace conventional metallic implants would be an intriguing accomplishment, especially in the orthopedic, craniomaxillofacial and dental fields where biointerfaces with outstanding osseointegration are in high demand. Guided by this purpose, in the ...
Given the many applications of half-metals in the spintronics devices, we investigated the half-metallic properties of the KP compound in rock-salt (RS) and cesium chloride (CsCl) structural phases by using density functional theory. The results indicated that the KP compound as the half-metal in the RS structure, in contrast to the CsCl structure, due to the small lattice constant and failure ...
Metallic glasses with nanostructures have gained broad interests in recent years as described the article, number 2200659 by Jiang Ma and co-worker. The functional applications of nano-engineered surface include green energy harvesting storage, medicine, neuroscience catalysis.
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...
