سنتز و مطالعه ساختار شیشه سرامیک طبی آپاتیت - ولاستونیت
سرامیکهای مدرن در تمام زاویای زندگی امروزی بشر وارد شده اند و کاربرد گسترده آنها علوم مختلف ، تکنولوژی و حتی پزشکی را تحت الشعاع خود قرار داده است . دسته ای از سرامیکهای مدرن، شیشه سرامیکها هستند. شیشه سرامیکهای ترکیبات آمورفی هستند که ذرات کریستالی در آنها امکان رشدئ می یابد و در حقیقت ساختار آمورف و کریستال بصورت یک مجموعه قابل ساخت است . کاربردهای طبی این ترکیبات بدلیل سازگاری بسیار خوب آنها...
15 صفحه اولکاربرد لجن کنورتور اسیدی شده (ضایعات کارخانه فولاد) به عنوان کود آهن در خاک‌های آهکی
The possibility of using a steel plant by-product (converter sludge) as an iron fertilizer was investigated. This compound consists of 64% Fe oxides. Considerable amounts of elements such as Ca, Si, Mn, P, and K are also present in the sludge. To study the converter sludge, an incubation experiment was carried out on three calcareous soils. Treatments were 0, 4, and 8 percent of converter sludg...

The objective of this study was to evaluate the possibility of using treated industrial by-products as a zinc (Zn) source and compare their Zn availability and efficiency to ZnSO4. A greenhouse factorial experiment in a completely randomized block design was conducted with corn (Zea mays L.) in triplicates. Treatments included three Zn sources (ZnSO4, IUT-UT in size of < 1 mm and IUT-UT in size...

There are no appreciable amounts of nickel resources in Iran; therefore, secondary resources of this element are to be more considered in future. Spent nickel catalysts that are used in various industrial processes are one of them. For example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...
