We are standing at the beginning of the industrialization of flexible thin-film transistor (TFT) backplanes. The two important research directions for the TFTs are (i) processability on flexible substrates and (ii) sufficient field-effect mobilities of electrons and holes to support complementary metal insulator semiconductor operation. The most important group of TFT capable semiconductors are...
فرایند ریخته گری تک غلتکه تسمه از روش های موجود در فن آوری نوین ریخته گری تسمه است که در تکامل فرایندهای ریخته گری مداوم نزدیک به شکل نهایی در دهه اخیر مقیاس صنعیتی به خود گرفته و کاهش قابل توجهی را در مصرف هزینه و انرژی در مقایسه با روش های سابق ریخته گری مداوم و نورد گرم ورقهای فلزی به دنبال داشته است. اگرچه در دهه های اخیر تلاش های پراکنده ای برای پیش بینی کارایی این فرایند به کمک مدل های عد...

The extent to which Chinese is represented phonologically or orthographically in verbal short-term memory was investigated using a short-term cued recall task (Tehan & Humphreys, 1998). In all conditions, proactive interference was induced by providing a retrieval cue (e.g. wild animal) that subsumed a to-be-recalled target word (e.g. leopard) and a to-beforgotten foil word (e.g. tiger), so tha...
Abstract This paper presents a novel technique to fabricate metallic nanowires in selective areas on Si substrate. Thermoplastic drawing of viscous glass from cavities etched can produce nanowires. The length and diameter be controlled by adjusting the conditions without changing mold. A thin metal shadow mask is stacked above mold during thermoplastic only specific locations. restricts flow pr...
A simple method is proposed to calibrate the energy of an electron beam. An electrical floating metal foil irradiated by incident electrons. The deduced from magnitude surface potential developed on conductor surface. measurement made outside vacuum chamber a metallic slab connected through coaxial feedthrough sample. calibration obtained this compared conventional based measuring position back...
The fracture toughness of a polymer-metal laminate composite is obtained by mechanical testing of a specimen containing a pre-crack. The laminate is a material used for packaging. It consists of a thin aluminium foil and a polymer coating. A centre cracked panel test geometry is used. Each of the layers forming the laminate is also tested separately. The result is compared with the measured fra...
