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...

Introduction: Despite the fact that the clinical implementation of polymer gel dosimetry has been facilitated after the introduction of normoxic gels, there are still complications in its clinical routine use that are under investigation. In the current work, the feasibility of using a normoxic polymer gel dosimeter named MAGICA has been investigated for use in our clinical brachytherapy applic...

Abstract Oxidised nanocelluloses have previously shown promise for the production of extruded filaments with high tensile strength properties. However, they also exhibit poor wet due to swelling upon immersion in water. This has resulted use chemical cross-linkers, or co-extrusion multivalent cations, cationic polymers, inhibit this. Here, we report on effect incorporating sugar alcohols (glyce...

In this study, the interactions of wheat starch (WS) and tannic acid (TA) were investigated for their gelatinization, pasting, structural, rheological properties digestibility starch. TA was either complexed with (WS-TA complexes) or mixed mixtures) right before characterization its properties. The increase melting enthalpy temperature range (Tpeak - Tonset) associated amylose-lipid complex in ...
