چکیده مقدمه: استفاده از زیرکونیوم به عنوان کور در ساخت روکش های دندانی با توجه به استحکام بالا، تطابق بافتی و در عین حال زیبایی آن موجب ارتقای پروتز های ثابت شده است. با این حال یکی از مشکلات اساسی در استفاده از روکش های بر پایه زیرکونیوم، تمایل کم زیرکونیا برای واکنش شیمیایی با پرسلن و سمان و در نتیجه باند ضعیف آن می باشد که موجب مشکلاتی از قبیل پریدگی و جداشدگی پرسلن می شود. هدف از مطالعه ح...
As an attractive alternative to organic and silica monoliths, hybrid organic-inorganic monolith somewhat combines the advantages of them, such as high surface area, excellent mechanical strength, and thermal stability. We have reviewed the preparation and application of hybrid monoliths in 2011 and 2013. The preparation approaches have been mainly summarized into three categories: (1) common so...
This review is devoted to non-hydrolytic sol-gel chemistry. During the last 25 years, non-hydrolytic sol-gel (NHSG) techniques were found to be attractive and versatile methods for the preparation of oxide materials. Compared to conventional hydrolytic approaches, the NHSG route allows reaction control at the atomic scale resulting in homogeneous and well defined products. Due to these features...
The release of nitric oxide (NO) from polymers has proven to be highly effective at inhibiting platelet adhesion and thus enhancing the blood compatibility of medical implants. Micropatterning techniques were used to design surfaces that release NO while preserving the underlying substrate for other applications (e.g., sensors). Micropatterned NO-releasing substrates based on aminosilane-contai...
