هدف از این تحقیق ساخت کامپوزیت های al/al?o?/sicبه روش متالورژی پودر می باشد. ابتدا زمان مناسب برای آسیاکاری و دمای مناسب برای تف جوشی در نمونه های al/20%sic تعیین شد. زمان آسیاکاری و دمای تف جوشی بهینه که به ترتیب 8 ساعت و ?c600 تعیین شد، جهت ساخت کامپوزیت های تقویت شده با ذرات sicو al?o? به کار گرفته شد. پودرهای مورد نظر ابتدا با درصد های حجمی al/20%sic، al/20%al?o?، al/5%al?o?/15%sic، al/10%a...
Tyack et al. cite three specific concerns in their commentary regarding Schorr et al. [1], and we respond briefly to them here. Quotes around normal font designate text from their commentary; italicized text in quotes is from the original paper [1]. Tyack et al. state that readers may misinterpret findings in Schorr et al. [1] because they aren’t “. . .adequately appreciating that that some of ...
Deoxyribonucleic acid or DNA based sensors, especially as humidity and alpha particle sensors have become quite popular in recent times due to flexible and highly optimizable nature of this fundamental biomaterial. Application of DNA electronics allow for more sensitive, accurate and effective sensors to be developed and fabricated. In this work, we examined the effect of different humidity con...
Unprecedented Al supersaturation in single-phase rock salt structure VAlN films by Al+ subplantation
Modern applications of refractory ceramic thin films, predominantly as wear-protective coatings on cutting tools and on components utilized in automotive engines, require a combination of excellent mechanical properties, thermal stability and oxidation resistance. Conventional design approaches for transition metal nitride coatings with improved thermal and chemical stability are based on alloy...
In this paper, the study of efficient bonding characteristics of AA6014 and AA1050 metal strips is carried out for Accumulative Roll Bonding (ARB) process. Among various Severe Plastic Deformation (SPD) techniques, ARB process is widely used due to its ability to produce ultra-fine grained ( UFG) or nanostructured bulk material. It has been observed that, if the experimental pressure and corres...

Obesity is an established risk factor for atrial fibrillation (AF).1 In fact, it has been reported that the increasing prevalence of obesity in the United States could account for up to 60 % of the increasing incidence of age and sex adjusted AF.2 Adipose tissue has been shown to be highly metabolically active and secretes several proinflammatory mediators; however, different fat depots differ ...
