Hydroxyapatite (HAp) crystals were prepared via an in situ biomimetic process in the presence of poly(vinyl alcohol) (PVA). The effect of

polymer amount and its molecular weight on the physical properties of the HAp ...

Hydroxyapatite/poly(vinyl alcohol) (HAp/PVA) nanocomposite samples were prepared by two

different methods of direct mixing and anin situ biomimetic HAp crystallisation in the presence of

polymer. Polymer ...

As the following reaction shows, in exothermic solution combustion synthesis (SCS) process, a high amount of gaseous by-products liberated in an extremely short period of time which could expel the oxygen from the reaction ...

با توجه به اهمیت روزافزون زیبایی در دندانپزشکی تقاضا برای جایگزینی ترمیم های آمالگام و ونیرهای فلزی با ترمیم های هم رنگ دندان بسیار افزایش یافته است. سرامیک های تجاری کنونی موجود زیبایی بسیار خوبی فراهم می کنند ولی معمولا ...

Apatite- mullite glass-ceramics have been developed recently as dental materials. The

effect of L1OZ and B2O3 content on the sintering and devitrification behaviour ol glasses in

the ...

The purpose of this study was to evaluate the effect of the amount of 3-Met[acryloxypropyl- trimethoxysilane (T-MPS)

coupling agent on some properties of an

experimental resin composite ...

Ceramic-metal composites (Cermets), which are a well-known category of advance materials, attract so much interest during decades due to their excellent abrasion and corrosion resistance. Powder metallurgy is a favorite ...

Ceramic metal composite (cermet)

هدف از مطالعه اخیر بررسی تاثیر حضور و یا عدم حضور بسترهای پلیمری بر مورفولوژی، اندازه ذرات و مقدار بار سطحی ذرات هیدروکسی آپاتیت بوده است. بدین منظور از یک روش رسوب شیمیایی اصلاح شده برای سنتز فاز مورد نظر استفاده گردید. ...
